Calories are important, but so is the glycemic index of what one eats and insulin response that drives weight gain/ loss.
There are those people who have genetic problems or take medications due to medical problems that affect the glycemic index that affect one’s weight, which are a very small minority of people. But for most people if you eat less than you burn you’ll lose weight. Eat the same amount of calories you burn and your weight stays the same. Eat more than you burn you,’ll gain weight.
There really aren’t any excuses, except for that small minority, to be overweight. The obesity “epidemic” could be over within a year if people to the time to take the fork out of their mouths by practicing some self-control and burning more calories than they ingest.
You burn 1,000 calories a day x 7 days and you burn 7,000 calories in a week. 3,500 calories is contained within one pound of human fat. This makes 7,000 calories two pounds that people can lose a week.
It’s time for people to stop making excuses about their weight.
