Weight-Calorie Connection
The Energy Equation –
Lose weight if you burn more calories than you consume
Gain weight if you consume more calories than you burn
1 pound of fat = about 3,500 calories
Eat 500 calories less per day than the amount you need to
lose 1 pound in 1 week. (500 cal/day x 7 days = 3,500
caloires)
Or burn 500 calories more per day through exercise

food groups. No less than 1,400 (talk to a doctor)

weights)
Physical Activity
Aerobic exercise (ex: running) –

rest
