Preventing Muscle Loss Through Diet

Why This Matters

Not all weight loss is the same. Losing muscle along with fat can leave you feeling weaker, slow your metabolism, and make it harder to keep weight off long-term. The good news: what you eat has a big effect on how much muscle you keep.

Diet Habits That Protect Muscle

• Prioritize protein at every meal — it gives your body the building blocks it needs to maintain muscle.
• Avoid going too long without eating; long gaps can encourage your body to break down muscle for energy.
• Don't restrict calories more than your care team recommends — very low intake accelerates muscle loss.
• Pair good nutrition with regular movement, especially strength training (see our Strength Training & Movement handouts).

Key takeaway: Muscle preservation is a team effort between eating enough protein and staying active — neither one alone does the whole job.

Watch for These Warning Signs

• Feeling noticeably weaker when doing everyday tasks (stairs, carrying groceries).
• Rapid weight loss paired with low energy.
• Clothes fitting looser everywhere, including places you'd expect to stay the same (like your upper arms or shoulders).
• If you notice these signs, let your care team know — we may recommend adjustments to your eating plan, activity, or a body composition scan to check your progress more closely.
• team, and message us with any questions.
