Zepbound (tirzepatide) reduces appetite and hunger, helping you eat fewer calories; this effect is almost immediate.
However, you might notice the impact of lower hunger wearing off after 4-5 days post-injection in the first month of taking Zepbound.
It can take around four weeks for Zepbound to reach a level in the body we call a steady state. A steady state is when the drug’s levels in the body remain consistent rather than spiking and falling.
Interestingly, this initial weight loss is no different to other weight loss treatments or the impact of diet interventions on weight loss. The real effect of tirzepatide is seen beyond three months...
