Weight loss/weight gain
Dietitian Nutritionist in India Article Page.

If enough weight is gained by way of increased body fat deposits, one may become overweight or fat, generally defined as having more body fat (adipose tissue) than is optimally healthy.

Weight gain has a latency period. The effect that eating has on weight gain can vary greatly depending on the following factors:

energy (calorie) density of foods, exercise regimen, amount of water intake, amount of salt contained in the food, time of day eaten, age of individual, individual's country of origin, individual's overall stress level, and amount of water retention in ankles/feet. Typical latency periods vary from three days to two weeks after ingestion.

Having excess fat is a common condition, especially where food supplies are plentiful and lifestyles are sedentary. 

As much as 64% of the India adult population is considered either overweight or obese, and this percentage has increased over the last four decades.
