Summary
On episode 178 of 40+ Fitness, Coach Allan shares the 11 biggest lessons from his own weight loss journey, the ones he wishes he’d understood from the start instead of learning the hard way.
His core argument is that weight loss isn’t a calories in, calories out problem. It’s a hormonal one. Insulin, ghrelin, leptin, and cortisol all have to be managed before the scale will move in a way that lasts.
He also makes the case that mindset matters as much as biology: a decision to change is not enough on its own, and the scale is a poor stand-in for actual health.

Key Takeaways
- Exercise matters, but it isn’t the weight-loss lever. Allan says trying to exercise your way out of a bad diet backfires. A slight calorie deficit driven by what and how much you eat does far more than burning extra calories in the gym.
- Insulin is what makes you store fat. Too much sugar and simple carbs spike blood sugar, which spikes insulin, and insulin’s job is to store that sugar as fat. As long as insulin is elevated, fat loss simply won’t happen.
- Ghrelin, the hunger hormone, runs on a circadian clock and peaks in the evening. That’s why hunger tends to hit later in the day even when everything else is on track, and why decision fatigue is highest at night.
- Leptin needs time to signal fullness. Eating too fast outruns the satiety signal, so you end up eating more than you needed before your brain catches up. Slowing down lets leptin do its job.
- Cortisol, the stress hormone, drives fat storage in the most dangerous spot: the midsection. Chronic stress keeps the body in a catabolic, fat-storing state, and that visceral fat is tied to heart attack and stroke risk.
- Sleep is the hormone regulator that ties everything else together. Good sleep supports a healthy circadian rhythm, which in turn balances cortisol, ghrelin, and sex hormones. Better sleep makes every other lesson on this list easier.
- A decision is not enough. You need commitment. Allan says he decided to get in shape in his 20s and 30s and still wasn’t there in his mid-40s. Real change required an emotional commitment tied to a clear “why,” not just a resolution.
- The scale does not measure health. Allan argues that focusing only on weight can lead you to unhealthy extremes; what matters is how you look and how you feel, not the number on the scale.
“If you don’t care about your body, you don’t care about your health, you just want to weigh less, then cut off one of your legs.”
