You're home with your son, which as nice as it is, can be a lot of stress and "down" time where you are probably bored and eat just for something to do. I stay at home too, with an 11 month old and a 3 year old. I'm about 40 pounds bigger than I want to be and I said enough! Since last week, I have lost 5 pounds. I work out about 40 min. a day (5-6 times a week) on an eliptical that I have at home. I love sweets and I haven't cut them out completely. I eat more in moderation now but I still eat some of the things I shouldn't, hard to break the habit. You're young so it'll be easier to lose the weight when you're ready to eat better. Just remember the food that you're eating will still be there to eat, after you've reached your goal and then you just have to watch how much and when.
You will get your body back!! J.
P.S. I use a product called carb blocker too, when I know I'm having a weak moment and from the results, I'd say it's working. Don't worry, it's a healthy supplement and has been scientifically researched, you won't have any side effects or long term problems. If you're interested in reading more about it, go to (jferguson.qhealthzone.com) and just type in carb blocker. Hope this helps you!!
