Ep. 209: Crash Dieting, Undereating, Metabolism, and Your Thyroid

Have you ever slashed your calories, skipped meals, or jumped on the latest crash diet—only to feel more exhausted, gain weight, or see your thyroid numbers worsen? You’re not alone. In this eye-opening episode, we dive deep into the long-term effects of crash dieting, undereating, and yo-yo dieting on your thyroid and metabolism.

We’ll unpack how extreme calorie restriction can trigger hormonal imbalances, slow down your metabolism, and even contribute to hypothyroidism -- making it worse! You’ll learn how the body adapts to chronic undernourishment, why water fasting and “metabolic confusion” might do more harm than good, and what strategies actually help restore metabolic health after years of dieting.

In this episode, you’ll learn:

• How crash dieting can suppress thyroid function and lower your metabolic rate

• Why undereating—even "clean eating"—can trigger weight gain and fatigue

• The hidden risks of water fasting and extreme carb cycling for people with hypothyroidism

• What metabolic adaptation is, and how to repair it

• How to safely rebuild your metabolism and support thyroid recovery

• Sustainable strategies for long-term weight and energy balance

If you’re struggling with weight management, energy crashes, or thyroid symptoms that won’t improve—despite eating “healthy”—this conversation is a must-listen. Tune in to discover practical, sustainable steps to rebuild your metabolism, support your thyroid, and ditch the diet cycle for good.
