Eating dinner at 10 p.m. instead of 6 p.m. may affect your blood glucose and the ability to burn fat.

Conventional wisdom is that a calorie is a calorie, no matter when you eat it, and that weight gain is caused by eating more calories than you use. Nutritionists call this the calories in, calories out theory of weight control.

But it might not be as simple as that. New research discovers that what time you eat may play a significant role in gaining weight.

A recent study finds eating a late dinner can cause weight gain and high blood sugar levels regardless of calories.

Researchers found that not everyone reacts the same way, and people who were accustomed to earlier bedtimes had the most weight gain from a late dinner. Night owls were the least affected by a change in mealtime.

According to researchers, this is strong evidence that eating a late meal causes weight gain even if you don’t increase the calories consumed.

Experts say, when working long days it’s a good idea to eat a healthy snack in the afternoon to curb your appetite for a late dinner.
