From the Guidelines
For obesity management in a non-diabetic adult male, the recommended dose of tirzepatide is 15 mg injected subcutaneously once weekly, as it has been shown to provide the greatest weight loss benefits compared to lower doses and other medications, with a mean weight loss of 20.9% at 72-week follow-up 1. The dose escalation for tirzepatide typically starts at a lower dose to minimize gastrointestinal side effects, but the goal is to reach the maximum recommended dose of 15 mg weekly for optimal weight loss benefits.
- The medication works by mimicking incretin hormones (GLP-1 and GIP), which reduce appetite, slow gastric emptying, and increase feelings of fullness.
- Common side effects include nausea, vomiting, diarrhea, and constipation, which often improve with time.
- For best results, tirzepatide should be used alongside a reduced-calorie diet and increased physical activity.
- The medication should be administered on the same day each week, and can be given at any time of day, with or without food.
- A recent meta-analysis of RCTs that included 12,371 adults with overweight or obesity without diabetes reported that 15 mg weekly of tirzepatide was associated with greater weight loss compared with other medications, such as semaglutide and liraglutide 1.

From the Research
Obesity Management with Tirzepatide
- Tirzepatide is a dual-incretin that has shown promise in managing obesity, particularly in adults with type 1 diabetes 2, 3.
- Studies have demonstrated significant weight loss in patients treated with tirzepatide, with one study showing a 21.4% reduction in body weight over 12 months 3.
- Tirzepatide has also been shown to improve glucose control, with reductions in HbA1c levels 2, 3.
- The medication has been found to have a positive effect on cardiovascular biomarkers, including improvements in blood pressure, lipid profiles, and estimated glomerular filtration rate (eGFR) 2, 4.
Dosage and Administration
- The optimal dosage of tirzepatide for obesity management in non-diabetic adult males is not explicitly stated in the available studies.
- However, the studies suggest that tirzepatide is typically administered via subcutaneous injection, with dosages ranging from 2.5 to 10 mg per week 3, 4.
Efficacy and Safety
- Tirzepatide has been shown to be effective in managing obesity, with significant weight loss and improvements in glucose control 2, 3.
- The medication has also been found to have a favorable safety profile, with few reported adverse events 2, 4.
- However, further studies are needed to fully evaluate the efficacy and safety of tirzepatide in non-diabetic adult males with obesity 5, 6.
