Fatigue may drive weight gain more than lack of exercise

Times Now News reports that fatigue and poor sleep could be a bigger factor in weight gain than simply not exercising enough. Constant exhaustion affects appetite-regulating hormones, increases cravings for calorie-dense foods, and reduces daily physical activity. An NIH-funded trial found that adults who slept more consumed fewer calories.

The outlet explains that sleep deficiency raises ghrelin, the hunger hormone, and lowers leptin, which signals fullness. Fatigue also makes exercise feel harder, leading to less movement and lower energy expenditure over time. Stress often worsens the cycle, promoting emotional eating and further disrupting sleep.

However, persistent fatigue may signal underlying health issues such as anaemia, thyroid problems, diabetes, or sleep apnea. Times Now News advises consulting a doctor if fatigue lasts weeks or is paired with unexplained weight gain, rather than simply pushing through with more exercise.
