Intermittent Fasting
Eating restricted to time windows — a structure some pair with GLP-1 therapy, with caveats worth knowing.
Intermittent fasting compresses eating into windows (16:8 daily being the common pattern) rather than prescribing foods. Trials show it works about as well as ordinary calorie restriction — it is a structure for creating a deficit, not a metabolic cheat code — and some people find the structure dramatically easier to obey.
Pairing it with GLP-1 therapy needs deliberateness: appetite suppression plus a short window can stack into chronic under-eating, protein targets get hard to hit in one or two meals, and oral semaglutide's empty-stomach morning rule must be reconciled with the window's timing. Reasonable with planning and prescriber awareness; counterproductive as an unexamined default. Hydration through the fasting hours is non-negotiable either way.
