Short, plain-language guides on GLP-1 therapy and metabolic health, written and reviewed by ZIVOLABS doctors. No clickbait. No miracle promises.

Caught early, prediabetes can often be reversed — and weight loss is the single most effective lever. GLP-1, alongside diet and movement, can pull blood sugar back into the normal range.

GLP-1 medicines were first developed for type 2 diabetes, and they remain among the best tools for it — lowering HbA1c, supporting weight loss, and in some cases protecting the heart and kidneys.

Mostly it changes intake, not metabolism. As you lose weight your calorie needs fall, which can slow progress; resistance training helps protect your metabolic rate.
The medicines are engineered to bind to blood proteins and resist breakdown, stretching their action to about a week — unlike the natural hormone, which lasts minutes.
Weekly semaglutide and tirzepatide have a half-life of about 5–7 days, so they take roughly 4–5 weeks to clear fully after the last dose.
Not directly — it works mainly by reducing how much you eat, which puts you in a calorie deficit so your body uses stored fat. Strength training steers that loss toward fat over muscle.
GIP is another gut hormone affecting appetite and fat handling. Mounjaro (tirzepatide) hits both GIP and GLP-1, and the combination appears to boost weight loss and ease nausea.
Your own GLP-1 is broken down within minutes, so the signal is weak. The medicines are modified to last about a week, giving a steady, stronger effect.
Both, in a sense. Your body makes the GLP-1 hormone naturally; the medicines are engineered, longer-lasting versions of it designed to resist rapid breakdown.
