Weight regain: why it happens & how to prevent it

Reviewed by Aion Medical Director name to follow Updated June 2026 5 min read
Short answer

Weight regain after injections is common but not inevitable. It usually happens when appetite returns and the medication stops before new habits are established. A gradual, supported off-ramp - with monitoring and protected muscle - gives results the best chance of lasting.

Being honest about regain is the first step to preventing it. The difference between people who keep results and those who don't is rarely willpower — it's usually structure. This is general educational information, not medical advice.
