155 | Why You’re Gaining Weight After 40 (The 3 Stages Perimenopause No One Explains)

Weight gain in perimenopause doesn’t happen randomly — it usually follows predictable stages. In this episode, Lara breaks down the 3 stages of perimenopause weight gain, why metabolism changes after 40, and how shifting hormones, stress, and insulin resistance can make fat loss much harder even if you’re eating the same and exercising like you always have. Many women in their late 30s, 40s, and early 50s feel like their body suddenly stopped responding. Sleep gets worse, belly fat appears, energy drops, and the strategies that worked for years no longer work. This isn’t because you lost discipline. It’s because your metabolism and hormones are changing. You’ll learn how progesterone decline, estrogen fluctuations, rising cortisol, and increasing insulin resistance affect fat storage, muscle loss, and energy levels during perimenopause and menopause. Understanding which stage you’re in can help you stop guessing what your body needs and start supporting your metabolism in a way that actually works after 40. In this episode you’ll learn: The early signs of perimenopause most women miss Why weight gain often starts in your late 30s or early 40s How hormone changes affect metabolism and fat storage Why belly fat becomes more common in late perimenopause How cortisol, insulin, and nutrient depletion contribute to weight gain What actually helps balance hormones and support fat loss after 40 If you’ve been struggling with weight gain, fatigue, bloating, poor sleep, or stubborn belly fat in perimenopause, this episode will help you understand what your body is doing and what to do next.
