Hang in there! When I started, it took me 2 weeks to lose one pound! It was so frustrating! After that I started losing regularly. For me those first few weeks were the hardest. Most times I've tried to lose weight I've given up in those first few weeks when the results are slowest.. but when I hung in there it was soooo worth it! It does get easier, and if you stick with it, the weight will come off! For me it's all about getting over the hurdle of those first few weeks and gaining momentum. You should be proud of yourself for deciding to make a change and working hard toward your goals! The fact that you say you've been eating healthy and exercising for 45 minutes at a level that is appropriate to you is a big accomplishment.. so many people want to lose weight but don't act on it, or give up after a day or two. You should give yourself a big pat on the back!. Stick with it! You will see results
