After a week or two of vacation, when regular diets and exercise routines are put on hold, weight gain is often an expected side effect. But the real challenge comes when you find it hard to cut back on eating even after returning to normal. Researchers now have an explanation: short-term, high-calorie diets do not just show up on the scale; they affect the brain.
A recent study published in the journal Nature revealed that even short-term overeating of high-sugar and high-fat foods can affect the brain of a healthy person, causing it to function similarly to that of an obese individual. A more alarming finding was that brain changes occur even before a person starts noticing weight gain.
