GLP-1 users lose 15-60% lean mass (meta ~25%). Prevention strategies: protein 1.2-2 g/kg, resistance training, creatine, HMB. New nuance: HMB shows age-dependent benefits — 2025 meta confirms modest gains in over-50s for lean mass, grip strength, function (3g/day, 12+ weeks). Baseline protein moderates responsiveness; ketosis may spare muscle; HRT combination shows promise. Whey protein price surge 250%. Weighted vests emerging as practical tool for menopause bone and muscle loss. New: fasting plasma amino acid profiles post-resistance exercise in older adults may inform protein timing strategies. Post-workout eating myth debunked – flexible timing within a few hours, focus on balanced meals with protein and carbs. New: inflammation may impair protein effectiveness (anabolic resistance) – relevant for midlife with chronic low-grade inflammation. New: butyrate (gut health) linked to improved balance, grip strength, gait speed in older men – actionable via fermented foods and resistant starches. New this session: age-related muscle gain difficulty article reinforces that strength training works at any age, even 90+. A well-structured guide on preventing muscle loss on GLP-1s provides consolidated advice. New nuance: DEXA scans are crude – lean mass loss may be overestimated; function often preserved; future muscle-building adjuncts (e.g., Lac-Phe pill) are in development. New practical guidance: GLP-1 users should shift focus from calorie ceiling to protein floor and calorie floor to preserve muscle. New this session: evidence-based diet plan for body recomposition (300-500 cal deficit, 1.6-2.2 g/kg protein) aligns with these strategies. New this session: protein guide for senior women (1.0-1.2 g/kg) adds demographic specificity. Also: rapid weight loss can cause acute sarcopenia and gaunt appearance; protein deficiency risk on GLP-1s even if proportional intake maintained; practical guide on losing fat without losing muscle (moderate deficit, protein floor, RT). New: protein guide includes GLP-1 and body contouring angles. New this session: strength training replacing weight loss as top gym goal reinforces muscle preservation priority. Also: bone density loss on GLP-1s added as related concern; prevention strategies include weight-bearing exercise, slow weight loss, protein/calcium. New this session: protein quality nuance added; midlife plateau article addresses anabolic resistance; strength vs cardio reinforces muscle preservation. New: Genentech pays $190M for muscle-sparing obesity drug targeting CRHR2 (orthogonal to GLP-1) – could change combo therapy landscape. New this session: creatine for midlife women – 70-80% lower stores, 2025 meta confirms lean mass/strength gains with RT, brain fog benefits. Body recomposition mindset shift from weight loss to strength, identity-based approach. DEXA vs MRI error caveat from recomposition deep-dive. New: maintenance and body recomposition playbook provides practical guidance for transitioning from weight loss to maintenance, including adaptive TDEE measurement and reverse dieting – critical for preventing regain and building muscle. Also: early-stage TOFA research shows potential to burn fat without losing muscle (mouse studies). A new full body workout plan for fat loss and muscle building reinforces these principles.
