I get asked a lot of questions on a daily basis regarding exercise and diet, all of which I am more than happy to help people with, but there are times when the same 'silly' questions or comments keep getting repeated. Remember the one about eating late at night? Well this is the latest one: "I need eat every 2-3 hours to boost my metabolism" which I've heard from both the general public and 'supposed' fitness professionals.
When you eat, your body needs to metabolise the food you have eaten and whilst it is true that eating boosts your metabolism, it's not the sort of boost you think it is. When you eat your body has to digest the food, which burns a certain number of calories, know as the 'thermic effect'. Now the amount of calories burned through the thermic effect, is directly related to the type and amount of food eaten.
Small Meal = Small Thermic effect (small amount of calories burnt)
Large Meal = Large Thermic effect (larger amount of calories burnt)
It doesn't matter whether you eat six small meals a day, three medium, or one large. If the calories are the same, so is the thermic effect or 'boost to your metabolism'.
So the next time somebody tells you, you must eat breakfast to boost your metabolism, kindly direct them to this blog. If that person is a fitness instructor, personal trainer, doctor or some other health professional, slap them first, then kindly direct them to this blog.
Thanks for listening
