what it claims

To lose weight sustainably, one should aim for a gradual loss of 5% of their body weight over 6 months, prioritize an overall improvement in diet (fiber, fermented foods) rather than restrictive diets, and sleep enough to regulate appetite hormones.

The recommended gradual approach is solidly supported by science. A meta-analysis published in the journal Circulation confirms that a weight loss of 3 to 5% already provides major benefits to overall energy and vitality, while being much more sustainable than rapid reduction. Regarding the failure of restrictive diets, long-term observational studies confirm that deprivation disrupts the body's natural balance, thereby promoting the yo-yo effect. Furthermore, randomized clinical trials support that the integration of fiber and fermented foods improves digestion and naturally supports satiety. Finally, the link between rest and weight is robust: review studies in the journal Sleep demonstrate that less than 6 hours of sleep disrupts biological hunger messengers (leptin and ghrelin), which stimulates the appeal for rich and sugary foods.

What the graded evidence says

Evidence
B
Effect
leptin/ghrelin and hunger after sleep restriction (RCT); net next-day energy balance after partial sleep deprivation (meta-analysis of RCTs) — sleep restriction decreased leptin, raised ghrelin, and increased hunger; meta-analysis found a net positive energy balance of roughly +385 kcal/day with partial sleep loss
Measured on
healthy adults in short-term controlled trials

What’s uncertain

Trials are short-term and use fairly severe sleep restriction; the exact calorie figure varies between studies. The direction — less sleep, more intake — is consistent, but long-term weight effects depend on many factors.
