Eating for weight loss


Q: I am exercising regulary, and I am not sure what or how much I should be eating to lose weight? How many calories, and what types of food can I eat?

A: Simply put, eat less calories than you burn per day.The more complex question, what IS that number? There is a fairly simple formula you can use to calculate how many calories a day you should eat to maintain your current weight. The secret is to eat aproximately 500 LESS calories than you need to lose weight.

Here is an excellent online calculator for BMI, BMR, and RMR

 BMI = Body Mass index
Keep in mind that BMI doesn't take into account differential weight for fat or muscle mass, it's possible you could have high percentage of muscle mass, a high BMI, but not be at increased risk for disease. Therefore, if you are an athlete, you may want to also use your body fat percentage measurement for a better idea of your fitness.
BMR = Base Metabolic Rate
RMR = Resting Metabolic Rate
As BMR and RMR only represent resting energy expenditure or calories burned during a day of rest, an adjustment must be made to reflect activity level. This can be done by multiplying by an activity factor.
These base numbers are then multiplied by an activity level ( ranging from sedentary to extremely active) to produce an estimate of  calories needed for maintenance of weight.

For example, if your BMR multiplied by your activity level (e.g. 1.5) is 1675 calories a/day, your target caloric intake should be around 1100 calories a/day for weight loss.
Good food choices include whole foods and grains, non-processed foods, and low fat options.
A great breakfast example is 4 egg whites, 1//2 cup steel cut oats and 2 tbs of salsa for flavor. Low calorie, low fat - high energy!!
