It doesn't have to be that simple. And go easy on the fruit and nuts. "Grok" didn't eat that many of either. And you can eat lots of foods that come in boxes and cellophane. But, no, nothing from clowns.
Start primal when you do not have energy/stamina demands for at least a week or two. You might want to consider the Archevore diet to start, including potatoes and white rice. (But keep coming to MDA for information. And I would recommend more vegetables than Archevore suggests.)
Yes, primal can help with diabetes.
Yes, primal can reduce the jiggles.
Some people throw out all non-primal foods, some don't. I didn't. But you do want to get rid of sugar, junk food, wheat, and all vegetable oils except olive and coconut.
Good luck with primal.
