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

Weight-Loss Strategies
In general – eat foods high in nutrients & low in calories
(such as vegetables, fruits, grains) & exercise
Eat 1,700 – 1, 800 calories per day of a balance of the
food groups. No less than 1,400 (talk to a doctor)
MODERATION!!! Eat sweets & “junk food” in small
portions and less often
Drink plenty of water – ditch soda & juices
EXERCISE 60 minutes per day
Weight-Gain Strategies
Increase calorie intake
Eat often & take second helpings
Eat nutritious snacks (such as an apple, celery & peanut
butter
Build muscle – go to the gym & “pump some iron” (lift
weights)
Physical Activity
Aerobic exercise (ex: running) –
burns calories helps lose fat
Weight lifting – increases muscle
mass & produces a firm lean body
shape
Muscle burns more calories than fat,
so the more lean muscle you have
the more calories you burn, even at
rest
