I was on my forum with other military spouses and came across this awesome site. I gained a lot of weight when i got pregnant with my daughter. 3 years later i was having a hard time losing the weight. Just recently I started having back pain and problems eating foods. so i have found that i had to go on a gluten free diet! it sucks because i dont know what to cook but i have to do it or i will never feel better. I have also been watching my calorie intake. My goal is to lose another 50 lbs.
