Summary
On episode 476 of 40+ Fitness, Coach Allan breaks down why the two camps people usually pick between for weight loss, calories in versus calories out and low carb versus keto, are both true and both incomplete on their own.
He lays out nutrition as three layers of increasing complexity: a simple calorie math layer, a macronutrient and insulin layer, and a hormone layer that even researchers haven’t fully solved. Each layer explains a different reason the scale doesn’t move in a straight line.
Allan closes with the four lifestyle levers, in priority order, for managing the hormones that actually control fat storage: nutrition, sleep, stress, and movement.

Key Takeaways
- The calories-in-calories-out versus low-carb debate is a false choice. Both camps are right at some level, but treating either as the whole answer ignores that weight loss runs through three layers: simple calorie math, macronutrients and insulin, and hormones.
- Calorie counts are estimates, not exact numbers, and small errors compound. Cardio machines can disagree by 150 calories an hour for the same effort, and being off by just 16 calories a meal can add up to roughly 10 pounds gained in a year.
- Frequent small meals keep you cycling between a sugar surge and fat storage. Eating six times a day gives insulin repeated small spikes to manage, which keeps shuttling glucose into storage and rarely gives the body a real chance to draw down body fat for energy.
- Cholesterol doesn’t cause the fire, it responds to it. Allan compares cholesterol to firefighters showing up at a fire: elevated cholesterol shows up alongside arterial damage caused by excess sugar and insulin, but that doesn’t mean cholesterol started the problem.
- Hormones are the third, hardest layer, and most can’t just be medicated away. Beyond thyroid, testosterone, and estrogen, hormones like insulin, cortisol, leptin, and ghrelin govern fat storage and hunger, and for most people there’s no pill fix, only lifestyle management.
- Manage hormones in this order: nutrition, sleep, stress, then movement. Whole food eaten in a balanced way signals the body it’s safe to release fat; poor sleep and chronic stress both signal danger through cortisol and push the body toward storing fat and burning muscle instead.
- You can’t out-exercise a bad diet. Movement is a communication tool, heavy lifting signals the body to build more muscle and bone, but it can’t compensate for a diet that’s working against you, and going harder on exercise before nutrition is dialed in usually backfires through poor recovery and elevated cortisol.
- Most people underestimate what they actually eat. Even nutrition-savvy people commonly underreport intake by around 29 percent through forgotten snacks and misjudged portion sizes, which is a big reason the math seems to not add up even when someone believes they’re compliant.
- Aging shifts the hormone layer, which is why the same approach stops working over time. Between roughly 45 and 65, declining thyroid output and falling estrogen and testosterone change both metabolic rate and where the body stores fat, which is why patience and sustainable incremental habits matter more than quick fixes as we get older.
