Struggling to lose weight despite your best efforts? Poor sleep could be quietly undermining your progress.
This video in my Science of Sustainable Weight Loss series explains the science behind sleep and fat loss and shares practical, evidence-based tips to improve your sleep routine, balance your hormones and support long-term weight management.
Summary
Research shows that getting fewer than seven hours of sleep for just two weeks can reduce fat loss by up to 50%. Lack of sleep pushes your body into fat-storage mode, disrupts hunger hormones and increases cravings for high-sugar, highly processed foods.
Sleep deprivation affects weight loss in four key ways:
- Reduces self-control: Tiredness weakens decision-making and increases stress, making healthy choices harder.
- Disrupts hunger hormones: Poor sleep raises ghrelin (the hunger hormone) and lowers leptin (the fullness hormone), increasing appetite and overeating.
- Impairs blood sugar control: Even a few nights of poor sleep can increase insulin resistance, making fat storage more likely.
- Slows fat loss: Studies show significantly reduced fat loss when sleep is restricted.
Quality sleep can really assist you on your weight loss journey. Watch the video for practical tips to improve your sleep.
