Hormonal
Tirzepatide administration significantly reduces body weight in overweight and obese individuals (BMI ≥28 kg/m²) compared to control, with the magnitude of weight loss being dose-dependent.
If you have a BMI of 28 or higher, Tirzepatide is a clinically proven option for significant weight loss. It works by mimicking hormones that regulate blood sugar and appetite. You take it as a once-weekly injection, starting at a low dose (2.5mg) and increasing to 5mg, 10mg, or 15mg depending on your response. Expect some gastrointestinal side effects like nausea or diarrhea, especially at higher doses, but most people tolerate it well. The higher the dose, the more weight you tend to lose.
The pooled findings showed that Tirzepatide vs control significantly reduced body weight (mean difference (MD): -7.38, 95% confidence interval (CI): -13.66 to -1.09)... The results of subgroup analysis showed that the trend of weight loss is dose-dependent (5mg: MD: -6.87... 10 mg: MD: -9.62... 15mg: MD: -11.00).
