When you are eating more than what is normal practice, there would be no surprise in seeing your weight go up. However, if you are gaining weight in spite of keeping the calorie intake under control, you have to look elsewhere.
Sleep loss is one of the major reasons. Sleep loss can produce weight gain in two ways. One of the reasons for lack of sleep is that you may be staying up late and during this process, you are more than likely to indulge in some snacking. Also sleep loss leads to an increase in the circulating hormones including the hunger hormone ghrelin. Thus, sleep loss promotes more eating without you realizing it.
Another reason for weight gain may be an underactive thyroid gland. Thyroid hormones promote overall metabolism. Thus, when the thyroid gland produces lower amount of hormones, metabolism slows down and this promotes weight gain.
Stress is another reason for weight gain. Stress increases the secretion of the stress hormone cortisol. This hormone promotes weight gain. This weight gain would also be experienced in a condition called Cushing’s syndrome where also there is increased secretion of cortisol.
Intake of some drugs can also lead to weight gain. Medications like the antidepressents, antipsychotic drugs, steroids, drugs for diabetes and hypertension can lead to weight gain.
Thus, when you put on weight, it is important to diagnose the problem correctly.
