How Sleep and Stress Affect Weight
Weight management is not only about food and exercise. Sleep and stress can strongly influence appetite, cravings, metabolism, energy, and motivation.
CDC guidance recognizes sleep and stress reduction as important parts of healthy weight management.
How poor sleep affects weight
Poor sleep can affect weight by:
Increasing hunger
Increasing cravings
Reducing energy for activity
Making meal planning harder
Increasing late-night snacking
Affecting blood sugar regulation
Making stress harder to manage
Research has linked disturbed sleep patterns with increased energy intake, including more snacking and higher-fat, higher-carbohydrate foods.
How stress affects weight
Stress can affect weight in several ways:
Increased cravings
Emotional eating
Higher intake of comfort foods
Skipped meals followed by overeating
Poor sleep
Less motivation to exercise
More alcohol or sweet drinks
Increased cortisol response
Stress can affect food cravings and that lack of sleep may increase appetite or cravings for high-fat foods.
The sleep-stress cycle
Stress can make sleep worse. Poor sleep can make stress feel worse. Together, they can create a cycle of fatigue, cravings, low motivation, and weight frustration.
What can help

Keep a consistent wake time
