Le jeûne fonctionne pour la perte de poids. La question intéressante est pourquoi — et les meilleures études suggèrent que la réponse est moins excitante que le discours.

Le Ramadan est la plus vaste expérience naturelle de jeûne. Ce que les études sur le rythme des repas et le métabolisme disent du poids, de la glycémie, du sommeil, et de qui doit être prudent.

Le petit-déjeuner est-il vraiment le repas le plus important ? Ce que disent les essais sur le rythme circadien et le moment des repas à propos du fait de le sauter, et à qui cela profite ou nuit.
Intermittent fasting produces weight loss. In head-to-head trials against ordinary calorie restriction, it produces roughly the same weight loss. That makes fasting a useful way to eat less rather than a metabolic trick — which is good news if you find it easier than counting, and irrelevant if you do not.
Start here
Yes for weight loss, and no better than calorie restriction when the calories are matched.
Protocol
The most popular protocol, and the one with the most disappointing controlled trials.
Protocol
Larger effects than 16:8 in the comparative data, and much harder to sustain.
Circadian
This is where fasting research is genuinely interesting. Late eating measurably changes energy expenditure.
Mechanism
Real biology, wildly overstated in humans. What has actually been measured, and at what fasting length.
Performance
Performance effects are small and depend heavily on what you are asking your body to do.
Metabolic
Where fasting moves markers, and where the movement disappears once weight loss is accounted for.
Safety
Pregnancy, type 1 diabetes, insulin-treated type 2, eating disorder history, and several medications.
What the trials actually show about semaglutide, tirzepatide and the rest of the GLP-1 class.
Energy expenditure, insulin resistance and metabolic adaptation, without the folklore.
Diets, drugs, behaviour and maintenance — ranked by the strength of the evidence behind them.
Sleep, circadian rhythm and the wearables that claim to measure both.
