Men vs. Women
Sorry ladies, but you have to eat fewer calories than men to lose weight. It isn't fair, but that's a fact!
As you get older, you burn fewer calories. Thus, the older you get, the harder it is to lose weight or even maintain your current weight.
As you age, you may need to increase exercise and/or eat fewer calories in order to maintain your current weight or to lose weight.
Interestingly, the more you weigh, the more calories you burn. Therefore, the more you weigh, the easier it is to lose weight. As you lose weight, you would need to keep
reducing the daily calorie intake in order to keep losing weight.
The taller you are, the more calories you burn. It would be easier for you to lose weight compared to someone shorter than you, but with the same weight as you.
How do we determine how many calories you should consume to lose weight?
We use Harris Benedict BMR equations revised by Roza and Shizgal to determine how many calories you burn per day.
It takes 3500 calories to lose one pound, and a realistic goal would be to lose 1 pound per week.
3500 calories divided by seven days in a week equals 500 calories.
Therefore, if you consume 500 calories less than you burn per day, then you will lose 1 pound per week.
Thus, we deducted 500 calories from how many calories you burn per day to find out how many calories you should eat per day to lose weight.
