The Hormonal Impact of Sleep Deprivation
University of Chicago research shows that just 4 nights of 4.5 hours sleep increases ghrelin (hunger hormone) by 28% and decreases leptin (satiety hormone) by 18%. This hormonal imbalance leads to consuming 300+ extra calories daily, often from high-carb, high-fat foods.
Metabolic Protection Strategies

Aim for 7-8 hours nightly to maintain healthy insulin sensitivity.
Minimum Threshold
Getting <6 hours sleep reduces fat loss by 55% even on same diet.
2. Protein Timing
Consume 20-30g casein protein before bed to stabilize overnight blood sugar.
Best Sources
Cottage cheese, Greek yogurt, or protein shake with fiber.
Exercise Considerations

Morning exercise improves sleep quality more than evening workouts.
Evening Alternative
If evenings only, finish 3 hours before bed and focus on yoga or walking.

Overtraining without adequate sleep increases cortisol and fat storage.
Rest Ratio
For every 2 hours intense exercise, add 30 minutes sleep that night.
