They unpack one of the biggest debates in women's health right now: is menopause-related weight loss resistance real, or are women simply underreporting calories? Dr. Campbell explains why the answer may be more nuanced than social media suggests, and why he is now dedicating much of his research career to studying resistance-trained peri- and postmenopausal women.

Vanessa and Dr. Campbell discuss:

• New research on menopause and "weight loss resistance"
• Why longitudinal menopause studies matter
• Rapid fat loss protocols without lean mass loss
• Protein-sparing modified fasting approaches
• Sleep deprivation and fat loss resistance
• GLP-1 medications, lean mass loss, and weight regain
• Why exercise is critical for maintaining weight loss
• Protein timing and body recomposition
• Reverse dieting and post-diet strategies
• Overfeeding carbs vs. fats
• Why high protein remains essential for body composition

This episode is packed with practical insights and cutting-edge science for anyone interested in fat loss, muscle preservation, menopause, and metabolic health.
