How do you lose 147 lbs in two months?
two months - let's call it 60 Days. 147/60=2.5
There's no way to lose 2.5 Pounds each day. that is not a realistic or sustainable loss rate.
Yes, but not always all in fat. If you typically don't drink too much water and all of a sudden start drinking 8-10 cups at least of water a day, you can lose up to 30 lbs in water weight. If you're looking to lose fat though, it is not healthy to lose that much weight in that time period unless you weigh over 300 lbs.
