Does Mounjaro cause muscle loss?
A SURMOUNT-1 substudy observed reductions in fat and lean mass during tirzepatide treatment. Lean mass is not a measure of muscle alone. These group results do not tell you how much muscle an individual has lost, and a change on the scale cannot answer that question. Read the body composition study.
What role do protein and exercise play?
The joint advisory from nutrition and obesity organisations includes adequate protein and strength training in caring for lean mass during GLP-1 treatment. Increasing protein alone does not guarantee muscle preservation. Nutrition and physical activity need to be tailored to the individual. See the joint advisory’s priorities.
If you have a protein target, ask your dietitian for examples of how it fits into your usual meals. This guide does not set a daily amount in grams.
What a food diary can show.
In BoraFit, each saved meal contributes to your daily summary. You can check estimated protein for the foods you logged and see whether you missed a meal.
For example, you logged eggs at breakfast and chicken at lunch but have not entered dinner yet. The app’s total reflects the entries made so far. Check ingredients and portions before drawing conclusions about the whole day.
A photo may also produce a different portion estimate from what you ate. Correct it with information you have, such as the food’s weight or label.
A diary does not measure muscle mass, strength or body composition. It also cannot confirm whether your diet meets your treatment needs. BoraFit offers its own adaptive targets; these do not replace targets agreed with your dietitian.
Questions to take to your care team.
- What protein target makes sense for me, and how can I spread it across my meals?
- How should we assess my strength and body composition over time?
- What changes should we discuss if I’m struggling to follow my eating plan?
Refer to your diary during the conversation and explain which values were estimated. To start organising your entries, see the guide to eating while taking Mounjaro.
Track the protein you’ve logged.
Photograph or describe meals, review the estimates and see your macros in BoraFit.
