The Claim
Following discontinuation of tirzepatide, 42% of the initial weight loss and 42% of the improvement in insulin sensitivity are reversed within four months in humans.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When people stop taking tirzepatide, they lose half of the weight they lost and half of the improvement in how their body handles insulin, within four months.
See the scientific wording
After discontinuation of tirzepatide, 42% of the weight loss and 42% of the improvement in insulin sensitivity are reversed within 4 months, indicating that metabolic benefits are not sustained without continued treatment.
When tirzepatide is stopped, the brain no longer receives signals to reduce hunger, so food intake increases. At the same time, the liver starts producing more glucose again, and fat tissue stops releasing stored energy as efficiently, causing weight and blood sugar control to return to previous levels.

1 studyStudy: 1676-P: Changes in Body Composition During and After Weight Loss with Tirzepatide
When people stopped taking tirzepatide, about half the weight they lost and half their improved blood sugar control came back within four months — just like the claim says.
