How much weight could I lose on a 500 calorie a day diet?

I am 5'7 and weigh about 160 something and I want to lose 30-35lbs. I am thinking doing it for about 3 weeks. Do you think I could lose that much in 3 or 4 weeks with that diet and some exercise? I don't need anyone to lecture me about the side affects and how unhealthy it is.

How to Lose Weight Fast Without Buying Anything

Recommended Answer:

1. You have to estimate how many calories you burn daily (your BMI). There are thousands of special calculators online. You only need to know: your exact height and weight, how active you are.2. After calculating that you have to keep in mind that burning 7000 calories equals 2.2 lbs (1 kg) lost. 3. Say you burn 1600 calories a day (even though that is what a teenage girl burns, so you would burn much more). Subtract 500, the amount you eat, and you'll get 1100. So, in a week you'd be losing about 3 pounds.

Other Answers:

• 500 calorie diet is like starving yourself. I wouldn't recommend it. You aren't going to get proper amount of vitamins/nutrients from that.
• tht is not unhealthy at all but 30-35 does not take 3-4 weeks bro, its more like 10-15 pounds, but it depends on your eating too, need fruits and veggies. I hope this helps, but if you do gain 30-35 no offence i know your saying dont lecture me abt how unhealthy tht is but it kinda is but its impossible to lose 30-35 pounds in a month ): I hope this helps.
