The only app built for GLP-1 muscle protection
GLP-1 medications like Ozempic, Wegovy, and Mounjaro suppress your appetite, but eating too little protein can cost you the lean muscle you have worked to build. MuscleGuard is designed to support you in hitting your dose-adjusted protein targets every day.

Thousands of posts across Reddit, TikTok, and GLP-1 communities share the same story: dramatic weight loss followed by unexpected muscle loss, weakness, and metabolic slowdown. The pattern is consistent, and most users say the same thing: nobody warned them about protein.
What the research shows: In the STEP 1 trial, approximately 39% of total weight lost on semaglutide 2.4 mg was lean mass, not fat (Wilding et al., NEJM 2021; DOI: 10.1056/NEJMoa2032183). Similar findings were reported in the SURMOUNT-1 trial for tirzepatide (Jastreboff et al., NEJM 2022; DOI: 10.1056/NEJMoa2206038). Research suggests that adequate protein intake and resistance training may help attenuate lean mass loss during weight loss (Lundgren et al., NEJM 2021; DOI: 10.1056/NEJMoa2028198). MuscleGuard is not affiliated with these studies.
The concept
This illustrative chart shows two possible outcomes during GLP-1 weight loss. Research suggests that without adequate protein and resistance training, a significant portion of weight loss may come from lean muscle (Wilding et al., NEJM 2021; Heymsfield et al., Obesity Reviews 2014). Not based on MuscleGuard clinical data.
Why this matters
GLP-1 medications are transformative for weight loss, but the muscle loss side of the equation is often overlooked.
Many prescribing physicians focus primarily on weight and metabolic markers. Detailed protein guidance adjusted to your specific GLP-1 dose may not always be part of the conversation.
Generic calorie trackers do not account for GLP-1 appetite suppression, dose-specific protein multipliers, or the unique training considerations that come with these medications.
When you eat in a caloric deficit, your body may break down muscle for energy. Research suggests that adequate protein plus resistance training can help support lean mass preservation during weight loss (Villareal et al., NEJM 2011).
