While wearables are a pretty good way to measure your heart rate, their ability to track calories is typically inaccurate, according to Stanford University Medicine. Exercising for time, however, is one way you can offset the inaccuracy of most calorie trackers.

Exercise helps burn calories and also maintains lean muscle mass while you're losing weight.

If you reduce calories without exercise, one-quarter of every pound you lose will come from lean muscle mass. Why does this matter? Your muscle mass affects your metabolic rate the rate at which your body burns calories. Increasing your muscle mass can boost your metabolism, which means your body will burn more calories even just performing day-to-day activities, according to Harvard Health Publishing.

Calculate a Caloric Deficit for Weight Loss. Within each age and sex category, the low end of the range is for sedentary individuals; the high end of the range is for active individuals. Due to reductions in basal metabolic rate that occur with aging, calorie needs generally decrease for adults as they age.

Estimated needs for young children range from 1, to 2, calories per day, and the range for older children and adolescents varies substantially from 1, to 3, calories per day, with boys generally having higher calorie needs than girls.
