Getting enough sleep can help you achieve your weight loss goals. Research shows an association between poor sleep and elevated body mass index (BMI). One possible cause is that sleep deprivation can increase your appetite, leading to weight gain. Individuals suffering from poor sleep have elevated levels of the hormones cortisol and ghrelin, which can both stimulate hunger.
Lack of sleep also changes the way you think, impairing decision making, judgement, and impulse control. When constantly tired, you are less likely to resist temptation and make healthy food choices. Lack of sleep may also lower your resting metabolic rate, decreasing your body’s calorie requirements.
Being tired all the time can really get in the way of meeting your exercise goals. When you lack the energy or motivation to get the exercise you need, sometimes a good night’s rest is in order. Lastly, poor sleep is associated with insulin resistance, which is a major factor in metabolic syndrome. Metabolic syndrome is a cluster of conditions obesity, type 2 diabetes, high blood pressure, and high cholesterol.
