Your Preferences, Your Metabolism; How to Customize the Fast Metabolism Diet

If you have dietary restrictions, the Fast Metabolism Diet can look challenging. What if you are a vegetarian, or vegan, or you must eat gluten-free? No problem! There are so many options on this diet that you can easily adapt to your dietary deal-breakers. Let’s talk about each one individually.


Any of the phases can easily be adapted to a vegetarian diet, especially if you are willing to eat eggs and fish while you are on the Fast Metabolism Diet. (I know that fish isn’t technically vegetarian, but there are those who will make exceptions and maybe you are one of them) If not, though, for any Phase 1 and Phase 3 recipes that include meat, you can substitute ½ cup cooked legumes, like lentils, black beans, white beans or any other phase-specific bean.

Phase 2 can be the most challenging for vegetarians because it is the low-carb phase, and we aren’t eating soy or soy-based products on this diet; but as long as you are willing to eat eggs and fish, you should be fine for those two Phase 2 days.


It’s easy to be vegan during Phases 1 and 3 because you can always substitute legumes for meat in any recipe. However, Phase 2 is more challenging. Protein-rich legumes and grains are just too high in carbohydrates for Phase 2. That’s why, as vegans, you get to break one rule. Just one. The soy rule.

Normally, I forbid soy on the Fast Metabolism Diet because of its plant estrogens and also because of how processed and genetically modified it tends to be. However, if you are vegan, I don’t want you to feel like you can’t do this diet. Therefore, during Phase 2, you may replace any meat with any of the following (but no other soy products)

  • Organic, non-GMO tofu
  • Organic, non-GMO soy tempeh
  • Organic, non-GMO edamame


Gluten-free is easy on the Fast Metabolism Diet because wheat, the primary source of gluten in most people’s diets, is already off the menu. However, there are a few gluten-containing products in the recipes and on the shopping lists. Don’t eat them. Sprouted-grain bread and products containing spelt, barley, Kamut, farro, and rye all contain gluten, so avoid those too. Conventional oatmeal also contains gluten.  

Instead, use gluten-free oatmeal and any of these gluten-free grains:

  • Amaranth
  • Brown rice
  • Buckwheat
  • Millet
  • Quinoa
  • Wild Rice
