Total calories in - BMR (basal/resting metabolic rate) - excess physical activity = total net calories for the day
If your total calories for the day after this equation are positive... you will most certainly gain weight. Because your activity and your intake vary from day to day, you may gain weight at a rapid pace, other times your weight will fluctuate back and forth and the pounds will creep on over time.
It takes approximately 3,500 ADDITIONAL calories burned to lose one pound. You could do this by reducing your calorie intake by 500 calories each day for one week. Your other alternative is to burn an extra 500 calories through physical activity. Ideally, you would want to implement both methods because cardio and strength training can provide other weight loss advantages and health benefits.
The first step is determining your BMR. There are many calculators online that will ask for your sex, age, weight, height and activity level. Here is mine:
Female, 34, 150 pounds, 5' 7":
| Activity Level | Description | Calories Burned Per Day |
|---|---|---|
| Low | You get little to no exercise | 1698 Calories/Day |
| Light | You exercise lightly (1-3 days per week) | 1946 Calories/Day |
| Moderate | You exercise moderately (3-5 days per week) | 2193 Calories/Day |
| High | You exercise heavily (6-7 days per week) | 2441 Calories/Day |
| Very High | You exercise very heavily (i.e. 2x per day, extra heavy workouts) | 2689 Calories/Day |
Seems pretty simple, right? Well, I know that this can be easier said than done. So tomorrow, I'm going to show you some EASY examples of how to reduce your calorie intake by those magic 500 calories a day or get extra physical activity to get you closer to that equal balance of calories in and calories out.
