I didn't even know that Bob Harper had a new book, I'll have to take a look. I completely agree with you about nutritionist or health people trying to promote protein or not eating white potatoes. I tried to follow the principles in Clean Eating in Tosca Reno's books, but she promoted combining a protein with a complex carb like many weight trainers do. And when I did this, I gained 5 pounds in two weeks!
i don't think that people have to concentrate on protein and I agree that when you focus on protein, you really just feel hungry all the time. I think that when people concentrate on filling up with vegetables and high fiber fruit like potatoes, beans, or brown rice, they are much more full and energized. I actually feel tired when I eat a lot of protein!
I am curious about you seeing your family and going to your dad's wedding. I have my brother-in-laws wedding coming up this Sunday and my husband's family coming into town today! They'll be here for a week and I know it's going to be hard, hard, hard. All they tend to eat is ham sandwiches. Even when I was a carnivore, you couldn't force feed me to eat ham sandwiches on fluffy white bread. But his family eats them like they're going out of style. Oh, well, I will have to get creative at the dinner reception and ask the caterers for something unique for me, while everyone else eats their greasy food.
I hope that you have a wonderful weekend and keep up the good work. I'm so excited that you'd like to become a personal trainer. That's great, and I think you should go for it!
