Question, for all you guys that have lost weight?

Lol. Maybe. When people say "you're full of ****"... well they could be talking about not only everyone but also themselves.
Pipes.. plumbing.. with just water going through look what they look like..lol
Were nothing but bags of turd sausage ready for linking. Once the navel swells...ta da.. full of ****. Lol
I guess I could have just said we humans are probably about 6 to 9 lb% ****/crud.
A good starvation, dehydration n rehydration challenge'll clean ya out..lol
10 lbs. per week might be too much too fast. You have probably lost muscle mass instead of stored fat. Slow down to 2 or 3 pounds per month by cutting out sugary treats and replace with protein to maintain muscle mass. You need to eat lots..but lo calorie nutritious foods. I went down 34 lbs in 10 months and lost my huge belly....i too am 70.
Good Luck.
