Level of Effort: Medium

Following McCullough’s recipes and suggestions will make it easier to stick to a low-carb way of eating, but you will still need to count carbs and protein.

Limitations: If you don't want to give up every slice of white toast or baked potato, you’ll struggle with this approach. McCullough admits it's not for everyone. Anyone with kidney damage shouldn't do this diet, since eating too much protein can overwork the kidneys.

Cooking and shopping: Living Low-Carb has tips to help you navigate the supermarket, and 175 recipes for meal planning.

Packaged foods or meals: No.

In-person meetings: No.

Exercise: Recommended.

Does It Allow for Dietary Restrictions or Preferences?

Vegetarians and vegans: The diet is already restrictive, so vegetarians, and especially vegans, will need to make an effort to find enough foods to eat.

Gluten-free: Going low-carb isn't necessarily the same as going gluten-free. You would need to read food labels to look for possible sources of gluten.

What Else You Should Know

Cost: None apart from your food.

Support: You do this diet on your own.
