The Fastest Way to Lose Fat Nobody Tells You This!
Whether fat loss is mostly about insulin or calories may depend on your starting point.
What this episode covers
- Insulin resistance may sit under several chronic conditions, and lowering insulin can support fat burning.
- The carbohydrate-insulin model adds nuance to the calorie-balance view rather than replacing it.
- The strongest practical levers are not exotic: lower-carb whole foods, more protein, strength training, and meal timing.
Why it matters
What changes is what you target. Calories matter; so does the insulin signal. Treating both gives more options when one alone has not worked.
What stands out
- Frequent eating, even of healthy foods, may keep insulin elevated all day; insulin sensitivity often improves more from giving the body time between meals than from changing food quality alone (clinical metabolism research)
- Fat cell size, not just total body fat, is associated with metabolic dysfunction; lean people can be insulin resistant if their fat cells are large and inflamed (adipose biology research)
- Strength training is a powerful way to improve insulin sensitivity, partly because muscle acts as a glucose sink; the effect complements cardio rather than replacing it (multiple RCTs)
Best-supported action
The single highest-leverage move from this episode, anchored in the strongest evidence the speaker presents.
Give insulin time to drop between meals; whether timing, food choice, or training matters most depends on your starting point.
Where to start
Small low-friction starters covering the main moves from this episode.
- Eat fewer refined carbs and ultra-processed foods
- Add strength training to your week, even briefly
- Give yourself longer gaps between meals when comfortable

- Lower the insulin signal across the day through some combination of carb quality, meal timing, and strength training, but how to weight these depends on your starting weight, blood glucose, age, and medications. Someone with prediabetes responds differently to carbs and meal timing than a lean, active person; the right balance shifts. One change alone (only cutting carbs, only fasting, only lifting) often gives partial results compared with combined approaches in trials. If a strict approach feels unsustainable, even one consistent change tends to matter: drop sugary drinks, add a walk after the largest meal, lift twice a week. Skipping the question of which lever fits often means months of effort with limited progress. Multiple RCTs support lower fasting insulin from low-carb eating, fasting protocols, and strength training.Strong evidence
- Add strength training, since muscle acts as a major glucose sink; this complements cardio rather than replacing it.Strong evidence
- If you take medication for blood sugar, blood pressure, or weight, coordinate any major dietary or fasting change with your clinician; effects can stack quickly.Strong evidence

Questions to take to your doctor
- Given my labs (fasting insulin, glucose, triglycerides), what dietary or training change would have the largest effect on my insulin sensitivity?
- If I am considering a low-carb or fasting protocol, are there medications I take that need adjustment first?
- What does my muscle mass and bone density look like, and would adding strength training help my metabolic profile?

Context
BYU metabolic researcher who frames insulin resistance as the connector across multiple cardiometabolic conditions. The insulin-resistance-as-cardiovascular-driver framing is broadly mainstream; the carbohydrate-insulin model as the primary driver of obesity is still actively contested in the energy-balance literature. Bikman has commercial exposure (co-founder of HLTH Code and Insulin IQ, author of Why We Get Sick), which is relevant context when he is the source of a specific protocol or substance recommendation, although it does not itself invalidate the underlying physiology he discusses. Strongest on mechanism; worth pairing with conventional clinical-outcome evidence when the conversation moves from mechanism to recommended daily protocol.
It does not prove that insulin alone explains all chronic disease, or that calories never matter. The carbohydrate-insulin model adds nuance to energy balance, not a replacement; some specific claims (about salt and the microbiome) are stronger than the evidence supports. This does not mean you should change or stop your current treatment on your own.
Where people go wrong
- Counting only calories while eating in a way that keeps insulin elevated all day.Weight may stick or come back, even on a calorie deficit, when insulin signals continue to push fat storage.
- Stopping a GLP-1 drug suddenly without building habits that maintain a calorie deficit.Weight tends to return quickly, often with the muscle and bone loss from the medication still present.
What to expect over time
- First 2 weeksIn some cases, hunger and energy stabilize as insulin spikes ease; visible changes are usually small in this window.
- Weeks 4 to 8Some people see fasting glucose, blood pressure, or fasting insulin shift on labs; subjective changes vary widely.
- Months 3 and beyondLong-term insulin sensitivity tends to track with sustained habits more than any short trial; results often plateau without ongoing strength training.
