I am all about losing weight quick BUT one of my main concerns with losing that weight so quickly would be sagging skin.
I am 70 lbs overweight and have some feedback from others....have a look at one of my previous posts...I was encourgaged to do 10 days on Master-Cleanse then 10 days fruit and veggies then 10 days on Master-Cleanse and so on....I plan on doing this for the next two months after I finish this cleanse....I am only on day 5 and would love to go for 14-21 days but I am not sure if I can do that so I would be happy to reach 10 again, then switch to fruit and veggies for 10 days...
I am sure you could do anything you put your mind too...I really think that 100 lbs of weight loss in 4 months would be hard on the body..I am not expert though....
Good luck and I look forward to reading your success on here.
