I've been struggling with the same challenges as yourself. My daughter is 3 and will be 4 at the end of May and I have about 40-50 lbs that I need to lose.
I just started the Nutrisystem diet. I'm on Day 14 and have already lost 7.6 lbs. You lose more at first, because you lose water weight as you begin to eat healthier and drink more water....your body then releases the water it has been retaining. But, you also begin to lose fat too. I'm already squeezing into a pair of pants that I hadn't been able to wear in a while (one size smaller).
The first week of my Nutrisystem was very hard, but now I'm on a roll and seeing the progress keeps me motivated. Eventually, the weight loss will slow down to probably 4-5 lbs. a month. Most importantly, this diet IS training me to think about what I eat and to eat more veggies, fruit & salads while dramatically lowering my carb intake. I use to eat so much bread, really at every meal. I love bread and I do miss it. But, eventually I will have it back and in a smaller portion size and only whole wheat/grain breads.
Also, it is important to know that I began walking the day I started my diet. I consistently walk everyday now and have gone from 20-30 minutes walking to 45 minutes to an hour already in my daily walk. This exercise/cardio is just as important as the better eating. I'm not concerned about going off the diet in 4 - 5 months and regaining, as I will have completely changed any bad habits I had and will have replaced them with good habits. I never was one to eat real poorly before or even overeat or binge at all...but I ate too much bread and my portions while appearing normal at restaurants or home for my meals were actually much bigger than we need or should have, I also did not eat enough veggies, fruit & salads...and didn't drink my 8-8 oz. glasses of water/day and snacked a bit too much. Plus, I was not consistent with exercise and got very little focused exercise. So, it all adds up.
The Nutrisystem diet/system/routine, will give my metabolism a boost.
If you decide to explore the Nutrisystem diet, the most cost effective way to do it is to buy it on the Auto-ship, unless you only have 10 lbs to lose. And, there are some promotions going on right now for 1-week free when you sign-up for the Auto-ship. I actually got 2-weeks free, plus free shipping, plus 10% off. So, if you go this route, let me know and I can try to send you all the important codes.
Hope this helps. Let us all know what you decided to do on the update. Take care. Many Blessings - L.
