How long to lose weight by exercise?

Answer 1

A pound of fat contains roughly 3200 calories, so whatever amount of time it takes at a certain intensity to burn 3200 calories is more or less how long it will take to burn a pound of fat. I say more or less because the majority of energy used during exercise comes from glycogen (carbohydrates) instead of fat. Assuming this glycogen were not immediately replaced, your body would have to get that energy from fat after exercise.

Answer 2

Eating calories are so much faster than burning them off, so any serious attempt at weight loss has to start with controlling your intake.

A snack(say a cupcake) that takes 5 minutes to eat can take 45-60 minutes to burn off.

If you're over eating it's pretty much impossible to exercise hard enough to lose weight through exercise alone.

Start with keeping a food diary. List everything you eat and drink during the day.

Figure out how many calories that is.

Figure out how many calories you should be eating.

Figure out how much you can eat to create about a 500 cal deficiency/day.

Start doing it.

Try to add some exercise. One hour daily, at a level that gets you decently sweaty and winded.

That depends on what form (or forms) of exercise you choose and your current degree of physical fitness. Cardioexercise is the best fat burning exercise and there are several choices of cardio.

That depends on your baseline level of exercise. If you are not currently getting any exercise then 3 times a week for 30 minutes is a good start. Couple this with a gradual reduction in caloric intake and you will start losing weight.

about 2500-3000 cal a day if you don't eat.

1 gram of fat = 9 calories

that's 280g of fat per day
