Narrowing your eating window also cuts the number of times you can spread out protein, and muscle building has to be triggered meal by meal; older adults need about 0.4 g of protein per kilogram of body weight at a meal to trigger it. The conflict is sharpest when older people try time-restricted eating.

The effect of time-restricted eating may depend on where the eating window falls in the body clock. In one small crossover trial of men with prediabetes, a 6-hour early window with dinner before 3 p.m. improved insulin sensitivity and blood pressure even with weight held steady. Shift work pulls eating out of step with the light-dark cycle, so results like these do not carry over.

Five common fasting methods

When you stop eating, the body does not shut down; it switches fuel tanks. It draws on the sugar stored in the liver first, and as that runs lower it breaks down more and more body fat. Every fasting method is, in the end, deciding one thing: how many hours a day you spend on the fat-breakdown side. There are five common ones:

16:8 (time-restricted eating, ): fast for 16 hours and fit meals into 8, typically noon to 8 PM or 1 PM to 9 PM, which amounts to skipping breakfast.14:10 or 12:12: looser time restriction; many people already go 12 hours without food.5:2 (also written 5-2): eat normally five days a week and only 500–600 kcal on the other two.Alternate-day fasting (ADF): one day at 0 calories or only 500 kcal, the next day eating normally.One meal a day (OMAD, also called 23:1).
Whichever one, the randomized trials reach a plain conclusion: the weight loss comes mainly from eating less, and it is about the same as eating less every day. If you take glucose-lowering drugs or insulin, do not start on your own: fasting can push blood sugar into a dangerous range. Shaking or cold sweats mean eat something sugary right away; confusion means get emergency care immediately. People who are pregnant or breastfeeding, or who have a history of an eating disorder, should not try it alone either.
