You've reached your goal weight and you are healthier and happier than you have been in a long time.
You've changed your life style, so why change anything?
Play a little with your food intake to see what keeps you balanced.
Don't be afraid to have 4 pieces of Hershey's Dark Chocolate Kisses
instead of 2-3.
Keep up your water intake and weigh once every couple of weeks to see if you are maintaining and adjust your meals and exercise program as necessary.
DO NOT revert to the habits you had pre-Spark!
A bag of potato chips? No. A half gallon of ice cream? No.
You know how to do it!
