A little bit of both. I've cut back a bit on carbohydrate intake, especially at night. I used to eat a giant meal for dinner but now it's a lowered carb and slightly higher protein diet with more salad greens. I think it's the lower carbs which does it. It means eating fewer calories also.
Congratulations. It's not an easy thing to do, but it doesn't have to be difficult either.
I have been in a program for the last 9 weeks or so and was going to unveil the before and after pictures in Mid October!
I will do it again starting Oct. 7th for another 12 weeks and hope to have even more impressive before and after shots. (I hope anyway!)
