Obesity risk and the impact of sleep on subcutaneous fat. (Part-1)

Genetics, lifestyle, and environment affect obesity, a complicated disorder. Sleep regulates body weight and metabolism, and little or poor-quality sleep may increase obesity risk. Let's examine sleep and subcutaneous fat.

Leptin and Ghrelin: Sleep deprivation disrupts hunger and satiety hormones. Sleep deprivation decreases leptin and raises ghrelin, which stimulates eating. 

Lack of sleep reduces insulin sensitivity, making blood sugar regulation harder. This insulin resistance may cause obesity over time.

Increased Caloric Intake: Sleep-deprived people may eat more calories and carbs to stay awake.

Subcutaneous fat: Fat under the skin. It's essential to the body, but genetics, diet, and exercise can affect its distribution.

Stress Hormone: Poor sleep raises cortisol. Chronically high cortisol levels enhance visceral fat accumulation. 

The effect on subcutaneous fat varies by person. Inflammation:

Inflammation: Poor sleep increases inflammation. Chronic inflammation may cause subcutaneous fat buildup.
