Why It's Time to Ditch the Spring Cleanse (and What to Do Instead)
Every spring, the wellness industry floods us with the same message: reset, detox, cleanse. Seven-day juice fasts. Fourteen-day elimination protocols. Expensive powders and programs promising to flush out everything you ate over the winter and leave you feeling like a new person by Easter.
I understand the appeal. After a long, dark winter, the idea of a clean slate is genuinely compelling. And the marketing is good — really good.
But after years of working with women in midlife, I want to offer you a different perspective. Not because I am anti-wellness, or anti-supplements, but because I am deeply pro-evidence. And the evidence on commercial cleanses is not what the wellness industry wants you to believe.
Let me walk you through why — and more importantly, what actually works instead.
Your Body Is Already Running a Sophisticated Detoxification System
Before we talk about what cleanses get wrong, let's start with what your body gets right — because it is quite remarkable.
Your liver, kidneys, gut, lymphatic system, lungs, and skin are collectively running a continuous, highly sophisticated detoxification operation 24 hours a day, seven days a week. No supplemental protocol required.
The liver alone performs over 500 distinct functions, including two-phase detoxification: Phase I, in which cytochrome P450 enzymes convert fat-soluble toxins into intermediate metabolites, and Phase II, in which those metabolites are conjugated with molecules like glutathione, glucuronic acid, and sulphate, rendering them water-soluble and safe for elimination through bile and urine. Phase III occurs in the gallbladder - these compounds are bound to bile, to be excreted in the stool. This is elegant, precise biochemistry — not something a seven-day juice fast is going to meaningfully improve upon.
The kidneys filter approximately 180 litres of blood per day, excreting waste products in urine. Your intestinal lining selectively absorbs nutrients while forming a barrier against pathogens and toxins. Your microbiome produces enzymes that assist in breaking down and neutralizing toxic compounds.
The honest truth? Your body does not need a cleanse. It needs consistent support. And that support looks very different from restriction.
But what if cleanses have worked for you before? Read on to find out why.
What the Research Actually Says About Commercial Cleanses
Despite the billions spent on cleanse and detox products annually, the scientific literature supporting them is remarkably thin.
A 2015 systematic review published in the Journal of Human Nutrition and Dietetics examined the evidence for commercial detox diets and found that while several pilot studies reported short-term improvements in subjective wellbeing, none of these studies were methodologically rigorous, most lacked control groups, and none identified a plausible biological mechanism by which the cleanse itself — rather than simply improved food quality and increased hydration — produced the effects.
The review concluded: "There is currently little convincing evidence to support the use of these diets."
What cleanses do reliably produce is a significant calorie deficit — and this is where the real problems begin.
Why Calorie Restriction in Midlife Backfires
The "eat less to lose more" logic that underpins most cleanses and diets was never a complete model of human metabolism. In midlife women, it is particularly counterproductive — and here is why.
Metabolic adaptation.
Research in the American Journal of Physiology has demonstrated that severe calorie restriction triggers a significant reduction in resting metabolic rate beyond what can be explained by lean tissue loss alone.
Your body, interpreting under-eating as a famine state, becomes measurably more efficient at using less energy. This is the metabolic adaptation mechanism behind the yo-yo cycle that so many women experience after cleanses: weight loss during the restriction phase, followed by rapid regain — and often overshoot — once normal eating resumes.
Cortisol elevation.
Calorie restriction raises cortisol, your primary stress hormone. In midlife women, this is particularly significant because declining estrogen reduces cortisol's natural buffering mechanisms. Elevated cortisol directly promotes visceral fat storage — the abdominal fat that perimenopausal women are already more predisposed to due to hormonal shifts. A cleanse designed to reduce belly fat can, through this cortisol mechanism, actively worsen it.
Muscle breakdown.
When the body is under-fueled, it draws on muscle protein for gluconeogenesis — the production of glucose to maintain blood sugar. Research consistently shows that up to 25–35% of weight lost through calorie restriction without adequate protein and resistance training is lean muscle mass, not fat.
In midlife women, where muscle loss (sarcopenia) is already accelerating due to declining estrogen, this is a particularly serious consequence. Muscle is your primary metabolically active tissue — losing it slows your metabolism, worsens insulin resistance, and makes long-term weight management significantly harder.
Hunger hormone dysregulation.
Restriction elevates ghrelin (the hunger hormone) and suppresses leptin (the fullness hormone). A 2011 study published in the New England Journal of Medicine followed participants for a year after calorie restriction and found that ghrelin remained elevated and leptin remained suppressed well beyond the period of active restriction — meaning that the intense hunger and cravings you feel after a cleanse are not a failure of willpower. They are a documented, measurable physiological response that can persist for months afterward. Yes, that’s why you’re always hungry.
What the Weight Loss on a Cleanse Actually Represents
If you have done a cleanse and lost weight, I am not dismissing your experience. But it is worth understanding what that weight actually was:
Water weight. Glycogen (stored carbohydrate) holds approximately three grams of water per gram. When carbohydrate intake drops sharply during a cleanse, glycogen stores deplete rapidly, releasing this stored water. The scale can drop 2–4 kg within the first few days — none of which is fat loss.
Reduced bowel content. Particularly if the cleanse involved laxative or fibre-heavy protocols, improved regularity and reduced intestinal content can account for 0.5–1.5 kg on the scale.
Calorie deficit-driven fat and muscle loss. The fat loss component is real — but so is the muscle loss, with the caveats described above.
When you return to normal eating, glycogen stores replenish (along with their water), bowel content normalises, and if the cleanse was severe enough to cause metabolic adaptation and muscle loss, weight can return faster than it left.
What Your Body Actually Needs This Spring
The good news is that everything you are hoping a cleanse will do for you — support your liver, improve digestion, lose weight sustainably, feel more energized and less brain fog, is entirely achievable. It just requires a different approach.
1. Support Your Liver Through Addition, Not Restriction
Rather than removing foods, the most evidence-based way to support your liver's detoxification capacity is to add foods that provide the raw materials your detox pathways actually run on.
Cruciferous vegetables — broccoli, cauliflower, Brussels sprouts, cabbage, kale — are among the most liver-supportive foods known to nutritional science. They contain glucosinolates that are converted in the gut to compounds including sulforaphane and indole-3-carbinol (I3C), both of which have been shown in multiple clinical studies to upregulate Phase I and Phase II liver detoxification enzymes, support the safe metabolism of excess estrogen, and reduce hepatic inflammation.
Allium vegetables — garlic, onion, leeks — are rich in organosulphur compounds that support glutathione synthesis. Glutathione is your body's master antioxidant and the primary molecule used in Phase II detoxification. Without adequate glutathione, Phase I detox produces reactive intermediates faster than Phase II can neutralize them, creating more oxidative stress rather than less. Supporting glutathione production is one of the most impactful things you can do for your liver.
Beets stimulate bile production and bile flow, which is essential for the transport and elimination of fat-soluble toxins and excess hormones. This is particularly relevant for midlife women: estrogen decline reduces bile flow efficiency, and sluggish bile is a significant contributor to the bloating, right-sided discomfort, and fatty food intolerance that many perimenopausal women experience.
Leafy greens — spinach, rocket, Swiss chard — provide magnesium (required for over 300 enzymatic reactions including multiple detox pathways), chlorophyll (which has been shown to bind to certain dietary carcinogens and assist with their elimination), and folate, which supports methylation — one of the critical Phase II conjugation pathways.
Green tea is a rich source of antioxidants called catechins, particularly epigallocatechin gallate (EGCG), which has been extensively studied for its hepatoprotective effects, its ability to enhance detox enzyme activity, and its role in reducing liver fat accumulation, helping to prevent fatty liver disease, which is very common among midlife women.
Citrus fruits provide vitamin C, which is required for glutathione synthesis, and d-limonene, found in the zest of oranges and lemons, which has been shown in animal and early human studies to induce Phase II detox enzymes. D-limonene can also help with acid reflux or GERD by helping to tighten the lower esophageal sphincter (LES).
Fresh herbs — particularly parsley and cilantro — provide numerous antioxidants including polyphenols and flavonoids that reduce hepatic oxidative stress, support kidney function, and assist with toxin binding and elimination.
The strategy here is meaningful: eat two to three servings of cruciferous vegetables daily, include alliums in your cooking consistently, start your morning with warm water and lemon, swap your afternoon coffee for green tea several days a week, and finish your meals with a handful of fresh herbs. These are not heroic interventions. They are small, sustainable cumulative habits with genuine physiological impact.
2. Optimize Bowel Regularity — Your Body's Most Direct Detox Pathway
Every bowel movement is a detoxification event. Bile — loaded with processed toxins, excess hormones (particularly estrogen), and metabolic waste — is released from the liver into the small intestine for excretion. If bowel transit time is slow or irregular, this waste sits in the colon longer than it should, and some of it — including estrogen — can be reabsorbed into circulation through a process called enterohepatic recirculation, making you feel “toxic” and sluggish.
This is one of the mechanisms by which constipation contributes to estrogen dominance symptoms in midlife women: bloating, breast tenderness, weight gain, mood changes, and worsening perimenopausal symptoms.
Supporting daily, well-formed bowel movements is therefore not a minor digestive concern — it is a core element of hormonal and metabolic health.
How Constipation Drives Gut Dysbiosis — and Why That Matters Far Beyond Your Digestion
What is less often discussed is what happens to your gut microbiome when bowel transit slows — and the downstream effects of that are significant enough to warrant their own conversation.
Your large intestine is home to approximately 38 trillion microbial organisms representing hundreds of distinct species. This ecosystem - your microbiome - is highly sensitive to its environment — and one of the most important environmental variables is transit time: how long stool, and therefore fermentable substrate, remains in the colon.
When transit time is normal, the balance of bacterial species is maintained in part by the relatively predictable flow of food residue through the colon. When transit slows, several important shifts occur:
Bacterial overgrowth and compositional imbalance.
Prolonged transit time creates conditions in which certain opportunistic bacterial species proliferate at the expense of beneficial ones. Research published in Gut Microbes has demonstrated a clear association between slow colonic transit and reduced populations of Bifidobacterium and Lactobacillus species — your key producers of short-chain fatty acids (SCFAs) — alongside increased populations of potentially pathogenic species including certain strains of Clostridia and sulphate-reducing bacteria.
Increased putrefaction.
As stool remains in the colon longer, bacterial fermentation shifts from saccharolytic (carbohydrate-fermenting, which produces beneficial SCFAs) toward proteolytic (protein-fermenting, which produces ammonia, hydrogen sulphide, phenols, and other cytotoxic compounds). These metabolites are not inert — they are absorbed through the gut wall, creating a systemic toxic load that the liver then has to process on top of its existing workload. This is the physiological basis of the "toxic" or "heavy" feeling that many chronically constipated women describe — it is not imagined.
Increased intestinal permeability. Dysbiosis and the accumulation of proteolytic metabolites compromise the integrity of the intestinal epithelial barrier. When tight junctions between intestinal cells loosen — colloquially referred to as "leaky gut" — bacterial toxins (lipopolysaccharides or LPS), partially digested food particles, and other inflammatory molecules enter systemic blood circulation. This triggers a state of chronic low-grade systemic inflammation that is now well-recognized in the research as a driver of insulin resistance, metabolic dysfunction, fatigue, and neuroinflammation.
The Downstream Effects: Metabolism, Mood, Energy, and Brain Fog
This is where constipation stops being a digestive inconvenience and becomes a whole-body health issue.
Metabolism. The short-chain fatty acids (SCFAs) produced by beneficial gut bacteria — particularly butyrate, propionate, and acetate — play a direct role in metabolic regulation. Butyrate is the primary fuel source for colonocytes (the cells lining your colon), and it also signals the release of GLP-1 and PYY, hormones that improve insulin sensitivity, reduce appetite, and support healthy weight regulation.
When constipation drives dysbiosis and SCFA production falls, this metabolic signaling is impaired.
Research published in Nature has demonstrated measurable differences in gut microbiome composition between lean and overweight individuals, with SCFA-producing species significantly depleted in those with metabolic dysfunction. Dysbiosis driven by constipation can therefore directly worsen insulin resistance and make weight loss more difficult — not through any failure of diet or exercise, but through impaired microbial metabolic .
Mood and anxiety. Your gut produces approximately 90–95% of your body's serotonin — not your brain. This serotonin is synthesised by enterochromaffin cells in the gut lining and is critically dependent on a healthy microbiome: certain Lactobacillus and Bifidobacterium species directly support the tryptophan-to-serotonin conversion pathway. When dysbiosis reduces these bacterial populations, serotonin production is impaired.
Additionally, the systemic inflammation generated by increased intestinal permeability activates the HPA axis, raises cortisol, and promotes a neuroinflammatory state that directly affects mood. A 2019 meta-analysis in the Journal of Psychiatric Research found a significant association between gut dysbiosis and both depressive and anxiety symptoms, with bidirectional causality — dysbiosis contributes to mood disorders, and mood disorders worsen dysbiosis through cortisol's direct effects on the microbiome.
Energy. The relationship between gut health and energy is multifactorial. Dysbiosis impairs the absorption of key energy-supporting nutrients including B vitamins (particularly B12, folate, and B6, several of which are synthesised partly by gut bacteria), iron, and magnesium. The systemic inflammatory state generated by leaky gut activates immune responses that are metabolically expensive — your immune system, when chronically activated, uses significant amounts of energy that would otherwise be available for normal cellular function. This is one of the mechanisms behind the persistent, unrefreshing fatigue that many women with gut dysbiosis experience — fatigue that does not respond to sleep because it is not caused by sleep deprivation but by chronic immune activation and impaired cellular energy metabolism.
Brain fog. The gut-brain axis — the bidirectional communication network connecting your enteric nervous system to your central nervous system via the vagus nerve, immune signalling, and circulating metabolites — means that what happens in your colon directly affects your cognitive function.
Bacterial metabolites including LPS, ammonia, and indole compounds produced during dysbiosis and intestinal permeability cross the blood-brain barrier or activate peripheral immune cells that signal the brain, promoting neuroinflammation. A growing body of research links gut dysbiosis to impaired working memory, slowed processing speed, reduced attention, and the subjective experience of mental cloudiness that patients consistently describe as brain fog.
A 2021 study in Cell demonstrated that microbiome composition influences hippocampal neurogenesis — the formation of new neurons in the brain's memory centre — providing a direct biological mechanism for the gut-to-cognition link.
For midlife women who are already navigating the cognitive effects of fluctuating estrogen, the addition of gut dysbiosis-driven neuroinflammation creates a compounding effect that can make brain fog feel genuinely debilitating. Healing the gut — starting with bowel regularity — is not a peripheral concern for cognitive health. It is central to it.
Supporting daily, well-formed bowel movements is therefore not a minor digestive concern — it is a core element of hormonal and metabolic health.
Dietary fibre is the most critical lever here. The current Canadian recommendation of 25g daily is already a significant underestimate relative to what the research supports for microbiome diversity and bowel health; I routinely encourage clients to aim closer to 30–35g. The shift from the average North American intake of approximately 15g to 30g represents a meaningful microbiome intervention in itself — diverse fibre sources selectively feed beneficial bacterial species that produce short-chain fatty acids, reduce intestinal inflammation, and improve motility.
Practical ways to increase fibre without overhauling your entire diet:
Add half an avocado to breakfast — 5g of fibre, plus monounsaturated fat that slows glucose absorption
Use chia seeds or ground flax in overnight oats or yogourt — 10g of fibre per two tablespoons, plus omega-3 fatty acids
Include one serving of legumes daily: lentils, chickpeas, or black beans added to a salad, soup, or grain bowl provide 8–15g of fibre per serving
Swap white rice or pasta for a whole grain several times per week
Eat the skin of your vegetables and fruit wherever possible
Add a fruit or vegetable based snack such as an apple or hummus and carrots, or add it to your protein snack
Hydration is the often-overlooked partner to fibre. Insoluble fibre absorbs water to create soft, well-formed stool — without adequate hydration, increasing fibre can worsen constipation. Aim for 2–2.5 litres of water daily, and more on days when you exercise.
The gut-brain connection is equally important and frequently underappreciated. Your enteric nervous system — the 500 million neurons embedded in your gut wall — is in constant bidirectional communication with your brain via the vagus nerve.
Chronic stress and unregulated cortisol directly impair gut motility: they reduce peristalsis, alter the gut microbiome, and increase intestinal permeability.
Addressing the nervous system is not a soft wellness add-on; it is physiology. Practices like diaphragmatic breathing before meals, a brief walk after eating, and intentional rest at mealtimes (rather than eating at your desk) directly support motility and digestion.
3. Focus on Sustainable Fat Loss — Not Water Weight and Muscle Depletion
If your goal for this spring is meaningful, lasting changes to your body composition, here is what the evidence actually supports.
Build and preserve muscle.
Skeletal muscle is your metabolically active tissue. Each kilogram of muscle burns approximately 50–100 additional calories at rest per day. In midlife women, where estrogen decline is already driving muscle loss at a rate of 3–8% per decade, resistance training is not optional — it is the single most evidence-based intervention for improving body composition, insulin sensitivity, and metabolic rate.
Two to three sessions per week of compound resistance training (exercises that work multiple muscle groups simultaneously) produces measurable changes in body composition within 8–12 weeks.
Balance blood sugar — consistently.
This is, without question, the most under-addressed driver of weight loss resistance in the midlife women I work with. Chronically fluctuating blood sugar drives elevated insulin, which actively prevents fat mobilization.
The three most impactful strategies:
always pair carbohydrates with protein, fat, or fibre to slow glucose absorption
never eat a significant carbohydrate load in isolation (ie a muffin or bagel on it’s own)
take a 10–15 minute walk after your main meals.
Research published in Diabetologia found that two minutes of light walking every 30 minutes improved post-meal glucose regulation significantly compared to prolonged sitting.
Eat enough to support your metabolism.
This is perhaps the most counterintuitive piece of advice I offer — and the most consistently transformative.
Women who have been under-eating for years are often in a state of metabolic adaptation that makes fat loss feel impossible.
Eating adequately (yes, that may mean eating more) with sufficient protein (1.2–1.6g per kilogram of body weight is well-supported in the perimenopause literature), combined with resistance training and blood sugar management, creates the physiological conditions in which fat loss becomes genuinely achievable — and sustainable.
Investigate root causes if weight is stubbornly unresponsive.
Weight that does not shift despite genuine lifestyle effort warrants investigation, not blame. Key areas to explore with your practitioner include:
fasting insulin and HOMA-IR (insulin resistance markers)
full thyroid panel including TSH, free T3, free T4 and thyroid antibodies
gut microbiome testing
inflammatory markers including hsCRP.
These are not exotic investigations — they are the clinical starting point for understanding why your body is holding onto weight.
A Final Word on Spring Resets
I am not opposed to the impulse behind the spring cleanse. The desire to feel lighter, cleaner, more energetic as winter ends is entirely understandable — and it reflects something genuinely healthy about wanting to take better care of yourself.
What I am opposed to is the exploitation of that impulse by an industry that sells restriction as transformation, and quick fixes as solutions to problems that are rooted in physiology and require consistent, evidence-based support to truly resolve.
Your body is not dirty. It does not need to be purged. It needs to be nourished, consistently, with foods that provide the raw materials for its own extraordinary self-regulation.
The foods listed in this article are not a cleanse. They are the foundation of a way of eating that supports your liver, your gut, your hormones, and your metabolism — not for seven days, but every week of the year.
That is the difference between a quick fix and a transformation.
What If This Spring Was the Last Time You Ever Had to Start Over?
I understand the appeal of done-for-you overly simplified detox plans. They often come with strict food guidelines that take the guesswork out of healthy eating, but it’s just not sustainble, and can actually set you back on your health journey.
I get it - decision fatigue is real. You’re a busy woman, you have enough to worry about and plan. It takes a lot of brain power to figure out what you should or shouldn’t be eating, and then plan meals every week based on that, but that’s where a professional comes in.
I’m a huge believer in not just telling you what to eat, but rather, educating you on why these foods are healthy, and most importantly how to build your own balanced meals, rather than relying on a meal plan. I’m also here to be your inspiration, your coach and your cheerleader when you get stuck, or have a setback. There is never any shame, blame or judgement. Instead, we examine what made those healthy choices hard for you, and build a plan to make it easier for you to succeed going forward.
Are we a good fit?
I work best with motivated, self-aware women who are genuinely ready to step off the quick-fix carousel — women who understand that sustainable results require a different approach, and who are willing to build healthy habits that actually fit their real life, without giving up the foods they love.
If that is you — if you are done with January Whole30s and spring juice fasts and the exhausting cycle of restriction followed by rebound — I would love to talk.
Book a complimentary discovery call with me today. We will look at what is actually going on in your body, identify the root causes of what is not working, and build a plan that is personalized, practical, and — most importantly — something you can sustain well beyond spring.
