Kenzie,
Core works if you truly follow the program. I lost almost 50 pounds a few years ago on Core, and got my Lifetime. I like Core because it really encourages healthy eating, as well as weight loss. I felt more energy and I felt really great about how I looked. Unfortunately, some stressful events and general laziness on my part has resulted in me gaining back about half what I lost.
But, it's not the program's fault.
I think what I failed to realize was that this is indeed a lifestyle change, and you can't go back to eating how you were before, ever. I know that now, so I think that's what is stopping me from re-comitting to Core completely.
Anyway, long answer to a short question. I think you've made a good choice to follow the Core plan. Make sure to follow it to the letter, give it a good month to get used to it, and drink plenty of water. Some of our members have noticed that water is even more important on this plan than others.
Good luck,and keep us informed! We love newcomers.
