418. Why "Calories In, Calories Out" Is Bullsh*t
Elite Coaching Cast
Understanding Metabolism and Its Impact on Women's Health
This chapter explores common misconceptions about metabolism and their impact on women's health, particularly focusing on the risks of extreme calorie restriction. It emphasizes the need for a holistic approach to metabolic health, taking into account factors like aging, hormonal balance, and the complexities surrounding thyroid treatment.
In this eye-opening episode of the *Grow or Die* podcast, I take a deep dive into the oversimplified concept of "Calories In, Calories Out" (CICO). We explore why this approach to weight loss and metabolism is outdated, ineffective, and, in some cases, even harmful. I break down the science behind metabolism, dispelling common misconceptions and explaining how factors like basal metabolic rate, hormones, and nutrient absorption play critical roles in achieving and maintaining a healthy weight.
You'll hear about real-world examples, like the contestants from The Biggest Loser and their struggles with weight regain, as well as the impact of severe caloric restriction on metabolism. We also cover the importance of understanding metabolic pathways, the role of polyunsaturated fatty acids, and how crash dieting can lead to long-term metabolic damage. Whether you're looking to optimize your health or curious about the science behind metabolism, this episode has the information you need to rethink how you approach weight loss.
