5 Ways Intermittent Fasting Backfires for Women Over 40 | Ep 458


Listen Later

Intermittent fasting is still the most popular nutrition advice on the internet. 

Skip breakfast, shrink your eating window, lose weight. But if you're over 40, this may not give you the results you want. It could even backfire.

Learn about the 5 specific ways intermittent fasting can backfire when your goal is losing fat and building muscle after 40. Philip examines a 2025 meta-analyses comparing IF to standard dieting, the challenge of getting enough protein in a compressed eating window, recent findings on cortisol and hormonal effects that especially affect women in perimenopause, and a surprising 2025 review that challenges one of fasting's biggest marketing claims (hint: it's about inflammation).

Plus, learn a structured meal timing alternative and 3 diagnostic questions to test whether your current eating window is causing issues for you.
