Hey hon. Its like I said in the other thread... there must be something making you gain. Are you drinking enough water? If you exercise quite a bit & you dont drink enough, your body is gonna retain that water. You'll also build muscle if you exercise a lot. And another thing is making sure you eat enough (of the right foods lol) to feed your body if you're exercising. Do you use weeklies? Do you eat a lot of bread? Too many bananas perhaps (this makes me gain)? Take a look at your food diary over the last 3 weeks and try comparing to your food diary on weeks you've lost weight & see if you can spot something abnormal.
All in all its only 2.5lb you've gained which isnt the biggest gain I've seen on here. Your body might need time to catch up and you might end up dropping 2lb outta nowhere (seemingly) next week or week after. Don't give up hon, everybody is gonna have a glitch like this at some stage... keep on going through... there's nothing to be gained by giving up now & it wont make you feel better. Give it another week anyway. Do you go to meetings? Did you ask your leader about the gains, they might notice something in your food diary?? xxx
