What is the most weight you have lost in one week ?

A few years back, I was able to lost a max of 22 lbs in a week. That was pure crash diet and extreme jogging and exercise. It wasn't healthy at all as I've noticed I got weaker after that month and then got really sick. I had to gain back a few just to feel better.

I am not a fitness freak. I don't check my weight so often although i go for regular walks and do yoga. The maximum that i must have lost must be half a Kg. Have a nice day.

I've never lost that much in a week. But once, I did the salad diet, with nothing but fresh fruits, steamed and fresh veggies plus legumes and such. All rolled into a salad. I ate two big salads daily and was never hungry. I got to eat cheese, too! Plus there was oatmeal with fruit for breakfast. And, I lost about twenty pounds in 2 months. I didn't eat any kind of meats for that time. Once I started eating beef and chicken again, all the weight came back. I've always heard that vegetarians are skinner. Maybe it's because they don't have the meat in their diet. My experience proved it to me! Good luck on your weight loss! Be well. BeautyQueen

10 lbs in a week. I didnot do anything special. I just play the dance dance revolution games in PS2 . at that time we had a big competition for dancing DDr in a mall. So I had to practice hard at home each day for hours to enter the competition. When I weigh in, I am kind "Are you kidding me?" Cause I never guess that just playing that games can lose me this much weight without any special diet.

Well,metschica25.I am considering on a diet now because the summer is coming!^^My friends and i run every night this semester.but after May day,we stoped and I still seems the same as before! And It is so great to lose so many weight.Keep going,but don't ignore your health!

I lost just under 12lbs my first week of Herbalife.

u lost a lot!! please give me the secret.. :) the most weight i ever lost in a week is about 1.5kg.. i think its about 3lbs.. i did on high protein n low carbo, but i found that it doesnt work so much..

haha well you done a lot better than me, ive probably lost max of 3 pound in a week :( i think that was water weight anyway, im only 9 stone something but want to get down to 8 n a half (as im only 5 ft 1 or 2 it would be the ideal weight for me) but i even went to the gym at one point .... and what did it do .... NOTHING lol my sister said maybe my body was turning it into muscle but i dont know, i didnt notice any change at all! I think my body struggles now tho to build muscle or lose weight unless im going full speed because that was what i was doing when i was training for the army
