She was in her thirties when she was diagnosed with colorectal cancer.


Surgery came first. A temporary ostomy was placed. She made it through.


And then, like so many survivors, she was handed a single photocopied sheet of dietary guidelines and sent home to figure out the rest.


She wanted to do everything right. She was motivated — deeply so. A diagnosis like this changes how you see your body and your health, and she was determined to use food to support her recovery and reduce her risk of recurrence.


But the hospital handout conflicted with what she was reading online. Different sources pointed to different foods, different approaches, different fears. She started cutting things out — whole food groups, one by one — trying to eat more safely, more carefully, more correctly.


She spent hours scanning the internet. What came back was a steady stream of bowel cleanses, detox programs, juicing fasts, elimination protocols. Each one promised clarity. Each one added more confusion.


She was losing weight. She felt weak most of the time. She had every intention of making a big lifestyle change and no energy to follow through. She was paralyzed — not by laziness or lack of willpower, but by fear. Fear of eating the wrong thing. Fear of making things worse. Fear that without a perfect plan, she shouldn't eat much at all.


This is one of the quieter crises of cancer recovery. Not dramatic enough to land you back in hospital. Significant enough to quietly derail everything.


What changed for her was not a new diet. It was understanding what her body actually needed — and why.


When she learned that her exhaustion and weakness were not a character flaw but a predictable consequence of muscle loss during treatment, and that eating enough of the right foods was not a risk but a requirement for recovery, something shifted. The fear didn't disappear overnight. But it had somewhere to go. She had a framework she could trust.


She started eating more consistently. Her energy returned — gradually, then noticeably.


She went back to work part time. She found enjoyment in food again. And when her digestion was unpredictable — which it sometimes still was — she had the knowledge to adapt, rather than retreat.


That is what nutrition support in survivorship can do.


Why Colorectal Cancer Recovery Is Nutritionally Complex


Colorectal cancer and its treatment create a specific and layered set of nutritional challenges that are rarely addressed in full by the healthcare system at discharge.


Surgery can change how the gut works. Depending on the location and extent of the surgery, the digestive system may function very differently after treatment. Bowel habits — frequency, urgency, consistency — can be unpredictable for months. For someone with a temporary ostomy, managing output, hydration, and nutrition requires guidance that a single handout simply cannot provide.


The gut-brain connection becomes hyperactive. After colorectal cancer treatment, many survivors become acutely aware of every digestive sensation. Every cramp, every change in bowel habit, every new food tried becomes a source of anxiety. This heightened vigilance — completely understandable after a serious diagnosis — can spiral into food avoidance that does far more harm than the foods being avoided.


Food fear drives under-eating. When everything feels potentially dangerous, the natural response is to eat less and stick to a narrow range of "safe" foods. But a severely restricted diet after colorectal cancer treatment means the body is not getting what it needs to rebuild. Calories are too low. Protein is too low. And the body — already depleted from surgery and treatment — begins to break down muscle to meet its energy needs.


The internet makes it worse. Search "colorectal cancer diet" and you will find an overwhelming volume of conflicting, fear-based content. Detox programs. Cleanses. Strict elimination protocols. Very little of it is grounded in the evidence base for cancer survivorship nutrition, and almost none of it accounts for the practical reality of recovery — fatigue, gut sensitivity, limited energy to cook, the need to actually enjoy eating again.


Muscle loss is happening quietly in the background. This is the piece most survivors don't hear about. Regardless of cancer type, treatment — chemotherapy, surgery, reduced food intake, decreased activity — leads to significant loss of lean muscle mass. In colorectal cancer survivors, this loss is often compounded by prolonged dietary restriction during and after treatment. And muscle loss has real consequences: persistent fatigue, physical weakness, metabolic disruption, and slower recovery.


The Surprising Similarity Between Colorectal and Breast Cancer Recovery


At first glance, colorectal cancer and breast cancer seem like very different diagnoses with very different treatment journeys.


And in many ways, they are.


But in survivorship — particularly when it comes to nutrition and recovery — the underlying physiology has more in common than most people realize.


Both groups experience significant treatment-related muscle loss. Both face fatigue that persists long after treatment ends. Both deal with metabolic disruption — changes in how the body regulates energy, processes nutrients, and responds to food. And both groups are often left without adequate, personalized nutrition support once active treatment is complete.


The primary difference is in how that muscle loss and depletion shows up day to day. For breast cancer survivors, it often presents as crushing afternoon fatigue, weight gain around the midsection, and cognitive fog. For colorectal cancer survivors, it is more likely to show up as physical weakness, weight loss, and an increasingly restricted relationship with food driven by digestive fear.


The starting point looks different. The destination is the same: rebuilding a body that has been through something significant, with food as one of the most powerful tools available.


What Nutrition After Colorectal Cancer Treatment Actually Looks Like


Effective nutrition support in colorectal cancer recovery is not about finding the perfect diet. It is about building a safe, sustainable approach to eating that the body can actually use.


Rebuilding food confidence before rebuilding the diet. For survivors who have developed significant food fear, the first priority is not hitting a protein target. It is understanding which foods are genuinely problematic for their individual gut — and which fears are based on anxiety rather than physiology. Many foods that survivors have cut out can be reintroduced, gradually and thoughtfully, with real benefit.


Adequate protein to reverse muscle loss. Protein is the foundation of recovery — it is what the body uses to rebuild lean muscle mass, support immune function, and repair tissue after surgery. After colorectal cancer treatment, protein needs are often higher than standard guidelines suggest, and meeting those needs requires a personalized approach that accounts for gut tolerance, appetite, and individual food preferences.


Enough total calories to stop the breakdown. When the body is not getting enough energy from food, it takes it from muscle. Many colorectal cancer survivors in the early months of recovery are not eating enough — not out of choice, but out of fear, fatigue, reduced appetite, and uncertainty. Restoring adequate caloric intake is one of the most important things a structured nutrition plan can do.


A gut-sensitive framework that is also nourishing. There is a real tension in colorectal cancer recovery between eating for gut comfort and eating for nutritional adequacy. Managing this tension — finding foods and meal patterns that are both tolerable and genuinely nourishing — is one of the most valuable things a specialized survivorship dietitian can help with.


Flexibility for unpredictable days. Recovery from colorectal cancer is not linear. Bowel habits fluctuate. Energy comes and goes. Knowing how to adapt your nutrition on difficult days — without retreating into restriction — is a skill that makes an enormous difference to quality of life.


You Don't Have to Figure This Out Alone


We are seeing more and more young adults — people in their thirties and forties — being diagnosed with colorectal cancer. Many of them are at an active life stage: working, raising families, managing careers and responsibilities. Recovery happens alongside real life, not instead of it.


And many of them are doing what the woman in this story did: searching desperately for answers in places that can't provide them, restricting more and more, feeling weaker and more depleted, and wondering why all their effort isn't working.


The answer is almost never that they need a stricter protocol. It is almost always that they need more — more food, more protein, more structure, and more personalized guidance than a post-surgical handout can offer.


Nutrition after colorectal cancer treatment is not about eating perfectly. It is about eating enough of the right things to give your body what it needs to rebuild.


That is entirely possible. And it does not require eliminating everything that brings you comfort or pleasure.


If you are recovering from colorectal cancer — or supporting someone who is — and you recognize the food fear, the fatigue, or the paralysis of conflicting information, I'd love to connect.

Frequently Asked Questions About Nutrition After Colorectal Cancer Treatment


What should I eat after colorectal cancer surgery?

Nutrition after colorectal cancer surgery needs to be individualized based on the extent of your surgery, whether you have a temporary or permanent ostomy, chemotherapy, immunotherapy or radiation treatment, your current bowel function, and your overall nutritional status. In general, the priority is eating enough total food and protein to support healing and prevent further muscle loss — while gradually expanding your diet as your gut tolerates it. A registered dietitian specializing in cancer survivorship can help you build a plan that is both gut-sensitive and nutritionally adequate.


Is it normal to lose weight after colorectal cancer treatment?

Weight loss during and after colorectal cancer treatment is very common, but it is not something to simply accept as part of recovery. Significant weight loss — particularly loss of muscle mass — slows healing, increases fatigue, and can delay return to normal activity. If you are losing weight or struggling to maintain your weight after treatment, nutrition support can make a meaningful difference.


Why am I so weak and tired after colorectal cancer treatment?

Persistent fatigue and weakness after colorectal cancer treatment are often related to muscle loss, inadequate nutrition during the recovery period, and the metabolic demands of healing from surgery and chemotherapy. If you are restricting your diet significantly, eating a very limited range of foods, or not meeting your protein needs, this is likely contributing to how you feel.


Can I eat normally again after colorectal cancer surgery?

For most colorectal cancer survivors a gradual return to a varied, nourishing diet is not only possible but important for recovery. The timeline and approach will depend on your individual situation, but the goal is always to expand what you are eating safely over time, not to remain on a restricted diet indefinitely. Working with a cancer survivorship dietitian can help you do this with confidence rather than fear.


Do you work with colorectal cancer survivors in Alberta?

Yes. I work with colorectal cancer survivors at all stages — during active treatment and throughout survivorship. All sessions are delivered virtually by secure phone or video, so I can support survivors anywhere in Alberta. Book a free Discovery Call to talk about where you are in your recovery.

She is nine months out from breast cancer treatment.

Treatment was long and hard. At one point it almost had to be delayed because of weight loss and weakness. She pushed through. She focused on protein, kept eating even when nothing appealed to her, and made it to the finish line.


She expected to feel better by now.


Instead, mornings are a struggle. Breakfast holds no appeal, but she forces down some oatmeal because she knows she should eat. Then the day begins — appointments, laundry, groceries, family care, all the tasks that used to feel ordinary. She tries to walk five kilometres most days, trying to go to the gym, trying to get her body back.


By the afternoon, she is exhausted.


She forgets things — where she parked, what was on the list she wrote this morning. Small moments that leave her in tears. She has gained weight around her midsection and feels uncomfortable in a body she doesn't recognize. In the evenings, all she can manage is the couch and something sweet that feels like a reward for getting through another day.


This is not what she thought breast cancer survivorship would look like.

Woman napping on the couch next to a greyhound

If this sounds familiar, I want you to know something important: this is not a motivation problem. It is not a willpower problem. And it is not all in your head.


What you are experiencing is what happens when the body goes through cancer treatment — and then doesn't receive the specific nutrition support it needs to rebuild.


Why Is Recovery After Breast Cancer Treatment So Hard?


My previous post explored why fatigue persists after treatment and what muscle has to do with it. The short version: chemotherapy, radiation, and hormonal therapy deplete lean muscle mass, disrupt metabolism, and shift how your body produces and uses energy. These changes don't reverse automatically when treatment ends.


But here's what I want to talk about today: why standard advice — eat a balanced diet, stay active, maintain a healthy weight — often isn't enough to address what actually changed in your body after breast cancer treatment. And what a more targeted nutrition approach can look like instead.


Why Nutrition After Breast Cancer Treatment Is Different


The woman I described above is doing many things right. She is eating. She is moving. She is trying.

But her body after treatment has different needs than her body before treatment — and those needs are specific.


Taste and Appetite Changes Are Real and Persistent


Chemotherapy and radiation can alter the way food tastes and smells for months after treatment ends. Foods that were once appealing may taste metallic, bland, or wrong. This makes it genuinely difficult to eat enough — especially protein-rich foods, which are often the most affected. Not being able to eat what you think you should eat is not a character flaw. It's what happens when appetite and taste have been disrupted by treatment.


Food Confusion After Cancer Is Exhausting


After a breast cancer diagnosis, many women are flooded with conflicting information — eliminate sugar, go plant-based, try intermittent fasting, take this supplement. Much of it is fear-based, and almost none of it is tailored to someone nine months out of treatment. Sorting through it while fatigued and foggy is an enormous and unnecessary burden.


Chemo Brain Affects Meal Planning Too


Treatment-related cognitive changes — often called chemo brain — affect concentration, memory, and executive function. Planning and preparing meals requires mental energy that is often in very short supply after breast cancer treatment. This is not laziness. The brain genuinely works harder for less output during this phase of recovery.


Metabolism Shifts After Breast Cancer Treatment


Hormonal changes from treatment — particularly for women managing menopause, estrogen suppression, or steroid use — affect how the body processes carbohydrates, stores fat, and regulates energy. Weight gain around the midsection despite eating carefully and staying active is a common and deeply frustrating outcome of breast cancer treatment.


It is also a metabolic signal worth paying attention to.


These are not generic nutrition challenges. They require nutrition support that is specifically designed around them.


How Nutrition Supports Recovery After Breast Cancer Treatment


Nutrition in cancer survivorship is not about dieting. It is not about restriction. It is not about achieving a certain look or number on the scale.


It is about giving the body what it needs to rebuild.


A structured approach to nutrition after breast cancer treatment can help with:


Rebuilding muscle mass after treatment. Muscle is the foundation of energy, metabolism, and physical strength. Rebuilding it after breast cancer treatment requires adequate protein — not a vague recommendation to "eat more protein," but specific targets, distribution across the day, and strategies that work even when appetite is poor or food aversions are present.


Stabilizing energy throughout the day. The cycle of exhaustion many breast cancer survivors describe — wiped out by afternoon, restless but depleted at night — is often connected to blood sugar regulation and meal timing. Small, strategic shifts in when and what you eat can create more stable energy without overhauling everything at once.


Working with the post-treatment metabolic shift. Changes to insulin sensitivity, cortisol, and hormone levels after breast cancer treatment affect how the body handles food. Understanding this — and working with it rather than against it — reduces frustration and supports the body in finding more stable ground.


Reducing food confusion and anxiety. A clear, personalized nutrition framework — grounded in evidence and built around where you actually are in recovery — removes the noise. You stop wondering whether every food choice is helping or hurting. That mental freedom matters enormously.


Building sustainable habits for long-term survivorship. Not a rigid meal plan you follow perfectly for two weeks before life intervenes. A way of eating that accommodates low-energy days, taste changes, busy weeks, hormone therapy fluctuations, and the unpredictable realities of life after breast cancer.


Why a Structured Approach to Cancer Survivorship Nutrition Makes a Difference


Information alone rarely closes the gap.


Knowing that protein matters after breast cancer treatment is not the same as knowing how much you specifically need, what sources work when appetite is low, how to distribute it across the day, or what to do when nothing sounds good.


Knowing that blood sugar regulation is important is not the same as knowing how to apply that practically to your meals and schedule.


The woman in this story is not missing information. She is missing a structure built around her — her history, her side effects, her current capacity, her goals.


That is what specialized survivorship nutrition care looks like. Not a generic handout. Not a list of foods to eat or avoid. A personalized, guided approach that starts from exactly where you are right now and builds forward from there — one that accounts for the real challenges of life after breast cancer treatment.


When Is the Right Time to Get Nutrition Support After Cancer Treatment?


I often hear from women who waited — who assumed things would improve on their own, or who didn't feel their struggles were "bad enough" to warrant support.


Here's what I know after working in oncology nutrition for over fifteen years: the earlier in survivorship you begin rebuilding muscle and metabolic stability, the more responsive the body is. Habits are easier to build before fatigue and weight changes become deeply entrenched.


Whether you are six months out of breast cancer treatment or two years out, you don't have to be in crisis to deserve support.


Feeling tired, frustrated, confused, and unlike yourself is reason enough.

Frequently Asked Questions About Working With Savour Nutrition


Getting Started

Who do you work with?

I work with people affected by cancer at any stage — during active treatment and beyond. Most of my clients are cancer survivors navigating recovery after treatment ends, when the support structure of the healthcare system often steps back but the body is still very much in the process of healing. While I have a particular focus on breast cancer survivorship, I have over 15 years of experience working across virtually all cancer types, from common diagnoses like breast, colorectal, and lung cancer to rarer cancers. If you are living with or beyond cancer, I'd love to connect.


What is the best first step if I want to work with you?

The best place to start is a free Discovery Call. It's a 15-minute conversation where we talk about where you are in your cancer journey, what you're struggling with, and whether working together is a good fit. There is no pressure and no obligation — just a chance to get clear on whether this is right for you. Book your free Discovery Call here.

Do I need a referral from my doctor or oncologist?

No referral is needed. You can book directly through the website. That said, I always work collaboratively with your healthcare team and can coordinate with your oncologist, GP, or other providers as needed.


What to Expect

What does a session actually look like?

All sessions are delivered virtually — by secure video or phone, whichever you prefer. We meet one-on-one, and the conversation is always built around you: your history, your current symptoms and challenges, your goals, and your real life. There are no rigid meal plans handed over at the end. Instead, we work together to build a personalized nutrition approach that is practical, sustainable, and grounded in the reality of recovery.


How is working with you different from the nutrition advice I got during treatment?

Nutrition guidance during active treatment is focused on getting you through — managing side effects, maintaining weight, staying strong enough for the next round. Survivorship nutrition is a different phase entirely. The focus shifts to rebuilding: restoring muscle mass, stabilizing metabolism, addressing the hormonal and metabolic changes treatment leaves behind, and building long-term habits that support your health for years to come. This specialized focus is what I do, and it is not something most oncology teams have the time or scope to provide in detail once treatment ends.


How is this different from seeing a general dietitian?

Cancer survivorship involves specific physiological changes — muscle loss, metabolic shifts from hormonal therapy, treatment-related cognitive changes, altered appetite and taste — that require specialized knowledge. A general dietitian may not have in-depth training in oncology nutrition. With over 15 years working in cancer care, including nearly a decade at Cancer Care Calgary, I bring a depth of specialization that allows me to address the nuances of your recovery in a way that general nutrition advice simply cannot.


Do you provide meal plans?

Sometimes, depending on what is most useful for you. For many clients, a rigid meal plan is not the most helpful tool — especially when fatigue, appetite changes, and cognitive load make following a structured plan feel like one more thing to manage. Instead, my focus is on building flexible, personalized nutrition frameworks that work in real life. For clients who genuinely benefit from more structure, meal planning support is available as an add-on service.


How many sessions will I need?

Most clients work with me for somewhere between 5 and 10 sessions, though this varies depending on where you are in recovery, the complexity of your situation, and your goals. Some people come in with a specific question and find one or two sessions give them the clarity they need. Others benefit from more sustained guidance as they rebuild over time. We will talk through what makes sense for you during your Discovery Call and reassess as we go — there is no pressure to commit to a set number upfront.


Practical Details

Where are you located, and can I work with you if I'm not in Calgary?

I am based in Calgary, Alberta, and all of my services are delivered virtually. This means I can work with cancer survivors anywhere in Alberta — whether you are in Edmonton, Lethbridge, Red Deer, a rural community, or anywhere in between. Virtual sessions by phone or video are just as effective as in-person appointments, and for many clients the convenience of not having to travel is a real benefit, especially during recovery when energy is limited.

Is virtual nutrition counselling as effective as in-person?

Yes. Research consistently supports the effectiveness of virtual dietitian services, and many clients find virtual appointments easier to fit into their lives — no driving, no parking, no waiting rooms. You can join a session from your home, your office, or anywhere that is comfortable and private. Sessions are conducted through a secure platform to protect your privacy.

Is your fee covered by insurance?

Alberta Health Care does not cover registered dietitian services in most outpatient settings. However, many extended health benefit plans — through employers or private insurance — do include coverage for registered dietitian services. I encourage you to check your plan details before booking. I am happy to provide receipts for insurance purposes. If cost is a barrier, please reach out — I want to make sure finances don't stand between you and the support you need.


About the Approach

Will this involve a restrictive diet or a lot of foods I have to give up?

Absolutely not. My approach is the opposite of restrictive. After cancer treatment, the body needs nourishment — not less food, but the right fuel, at the right times, in amounts that actually support recovery. I work from a weight-neutral, non-diet framework. We focus on what to add and how to support your body, not on what to eliminate or avoid. If you have spent time fearing food or feeling overwhelmed by conflicting advice about what cancer survivors should eat, part of our work together is clearing that confusion and rebuilding confidence.


What if I'm not sure nutrition is what I need right now?

That's exactly what the Discovery Call is for. Many people come to me uncertain — they know something isn't right, but they're not sure whether nutrition is the missing piece or whether they're "struggling enough" to warrant support. My answer is always the same: you don't have to be in crisis to deserve help. If you are fatigued, frustrated, confused about what to eat, uncomfortable in your body, or simply not feeling like yourself after cancer treatment, that is enough. Let's talk.

Fatigue is one of the most common and persistent side effects after cancer treatment, and one of the most distressing symptoms reported by cancer survivors in Alberta.


It’s expected that once chemotherapy or radiation ends, energy will gradually return. Instead, months even years later survivors still feel depleted, weaker than before, and unsure why their body doesn’t feel the same.


I’ve worked with many women who feel like they are doing everything they were told to stay healthy after treatment, but they still don’t feel like themselves.


You may have been told to:

  • Eat a balanced diet 

  • Maintain a healthy weight 

  • Stay active


All reasonable advice but has it worked for you?


For many survivors, it isn’t specific enough to address what actually changed in the body during treatment.


How Cancer Treatment Affects Muscle and Strength


Cancer treatment can significantly reduce lean muscle mass and strength.


This loss can occur due to:

  • Inflammation

  • Reduced food intake 

  • Hormonal shifts 

  • Decreased activity during treatment 

  • The body prioritizing immune repair and healing


Even when body weight stays stable, muscle mass can decline.


Research on cancer-related body composition changes shows that low muscle mass is associated with:

  • Reduced physical function, ability and resilience 

  • Increased treatment-related complications and mood disorders 

  • Persistent fatigue and overwhelm 

  • Lower quality of life and wellbeing


Muscle is not just about strength or appearance.

It plays a central role in how the body regulates energy, metabolism, and physical capacity.


Why General Nutrition Advice Isn’t Always Enough To Improve Fatigue After Cancer Treatment


General nutrition advice is important for overall health.

But recovery after cancer treatment is more complex.


Rebuilding muscle and restoring steady energy often requires a more intentional and personalized nutrition approach.


This may include:

  • Adjusted protein intake to support muscle repair 

  • Sustainable meal frameworks that provide consistent energy 

  • Gradual nutrition goals based on individual recovery needs 

  • Symptom-smart strategies to support appetite and digestion


Without this focus, recovery can stall.


It’s not a willpower problem.

It’s a physiology problem.


A Different Way to Think About Recovery After Cancer


A diet won't help you improve fatigue after cancer treatment. Instead of focusing on shrinking the body after treatment, recovery requires rebuilding it.


Rebuilding strength. Restoring steady energy. Supporting resilience and stability.


This is not about dieting.

It’s about restoring capacity.


Many women are never offered structured support in this phase of recovery. They expected to move on after treatment, without a clear plan for rebuilding strength or energy.


That gap is where specialized survivorship nutrition care can make a meaningful difference.


What Structured Survivorship Nutrition Support Can Look Like


A guided, evidence-informed approach to muscle and energy recovery may include:

  • Individualized protein targets 

  • Practical meal systems to reduce overwhelm and food anxiety 

  • Monitoring symptom and lifestyle changes during recovery 

  • Coordinated exercise referrals when appropriate 

  • Ongoing guidance and adjustment


Recovery deserves more than general advice.


If you are still struggling to recover your strength and energy, book your Recovery Call now.



Frequently Asked Questions About Fatigue After Cancer Treatment


Why am I still tired months after cancer treatment?

Fatigue after cancer treatment can persist due to a combination of factors including muscle loss, metabolic changes, inflammation, and reduced physical activity during treatment.


Can cancer treatment cause muscle loss?

Yes. Chemotherapy, radiation, reduced activity, and changes in appetite can lead to a loss of skeletal muscle mass during treatment, even when body weight stays the same.


Can nutrition help rebuild strength after cancer?

Nutrition plays an important role in recovery after treatment. Adequate protein intake, consistent meals, and strategies that support muscle rebuilding can help improve strength and energy over time.
