Insufficient Sleep and Obesity:

Lack of sleep disrupts hormones that regulate hunger, such as leptin and ghrelin, leading to increased appetite and potential weight gain.

Studies have shown a clear link between insufficient sleep and higher body mass index (BMI).

Other Statements:

Depression and Weight:Depression can affect weight, often leading to weight gain or loss.

Work Stress and Diabetes:Stress is linked to type 2 diabetes, not type 1.

Activity Levels:While obesity can reduce activity levels, it is not universally true that all obese individuals are less active than those of normal weight.
