How to Eat and Fast around the Menstrual Cycle and Peri-Menopause.

Jason Fung

Summary

Marketers are increasingly addressing the issue of "bullspend" in advertising, where campaigns generate impressive metrics like impressions but fail to translate into actual revenue. This phenomenon highlights the need for businesses to focus on tangible results rather than just reach. LinkedIn is cited as a platform that delivers the highest return on ad spend among major networks, encouraging advertisers to prioritize revenue generation over mere visibility.

Dr. Jason Fung discusses the impact of hormonal changes on women's fasting and dietary practices throughout the menstrual cycle. He explains how estrogen and progesterone influence appetite and metabolism, suggesting that the follicular phase, characterized by increased estrogen, is ideal for fasting due to reduced hunger and a higher propensity for burning carbohydrates. Conversely, during the luteal phase, appetite increases, making it a better time for low-carbohydrate diets.

Fung also explores the effects of menopause on weight gain and metabolism. He notes that declining estrogen levels lead to increased appetite and a shift from fat burning to carbohydrate burning, which can contribute to weight gain during this transitional period. Research from the biometrics company Lumen supports these findings, emphasizing the importance of personalized dietary approaches based on hormonal changes.
