YOU DONT nEED MORE LEMONADES!

you dont need to drink more lemonades to do this if you are fatter.
having more calories than you should along with the wrong kind of calories is most likely what made them fat in the first place.

fat holds toxins. so for someone who is really heavy they may have a heavy detox reaction,loose skin. they should first clean up thier diet so there are less detox symptoms to deal with during the fast and post fast. cravings for junk foods is going to be something they are probably going to be fighting.

to tighten up skin you can do dry skin brushing. google it on how to.
the heavy person needs to drink half thier weight in water daily in ounces.
have them start doing that right now. they are probably so toxic they may feel a little ill from that. even when eating healthy. i myself felt a detox from doing that when i first started cleansing. i was a normal weight with a bad diet history.
