Well fasting is not all bad if you do it right...i fast for religious reasons and i find that ive lost about 5lb's in like a week and a half...it all depends on how you eat...like me when were fasting were supposed to eat like in the morning like at 5am like a light meal..full of fiber and stuff thatll sustain u for the rest of the day and we break our fast like at 5pm and ur not supposed to over eat...i usually eat a small meal with alot veggies...and around 7 i usually exercise and i dont eat after that...im never usually hungry...but i dont do this everyday...its just a month that we do it...after that i come back to my normal eating habits..so fasting is not bad as long as u do it RIGHT...but its not something that u shuld do all the time
