How fast can you realistically Lose Weight in Three Weeks?

Answer 1:

Just saying that you’ll more than likely just gain the weight right back since you’re rushing weight loss (it never ends up well) you’ll end up losing a shit ton of muscle and start rebounding immediately

The goal for a healthy weight loss is 1lb per week (you’ll lose more at the start since you’re losing water) to do this, you have to be at a 500 calorie deficit

Answer 2:

It depends on your starting weight and BMI, but if you fast for most of that time then it’ll be a significant percentage of your body weight. Say you start off with a 72hr fast, then go into a couple of days of clean eating OMAD, then back to a 72hr fast then rinse repeat. You’d lose a LOT and so long as you’re not already underweight, the health benefits would also be significant. r/fastingscience

Answer 3

There are many weights to lose weight quickly but few are healthy. If you want to lose weight OP please be cautious of the dangers of losing weight quickly, it's a much greater risk than gaining weight and most people don't realize this.

Answer 4:

Well, the average person can lose 1000 extra calories a day without negative side effects, and 3500 is about 1 pound. So if you can count your food and burn it properly, you can lose about 6.

Answer 5:

Try to shoot for 1% per week. So if you are 240 lbs. that will be under 7. If you are 160, more like 4. Slow is safe and sustainable.
