Proponents of low-carb high-healthy-fat moderate-protein (LCHF) claim that diabetes can be reversed and blood glucose will be in the normal non-diabetic range as long as the patient maintains a low-carb high-fat lifestyle. It should be noted that this is not a low-carb high-protein approach. This dietary approach accommodates vegetarians/vegans as well as non-vegetarians. A typical LCHF diet consists of a protein source (meat, eggs, cheeses, nuts and seeds) and a foundation of green leafy and cruciferous vegetables and other low-carb vegetables. It omits all grains, legumes, starchy vegetables, and most fruit except for a few berries.

Approach Low-carb, High-fat (Ketogenic)
Major Proponents Eric Westman, Richard Bernstein, Jimmy Moore, Jason Fung, Ron Rosedale; earlier proponent Dr. Robert Atkins
Lifestyle Required LCHF may be carnivore, “clean-meat” non-vegetarian, pescetarian, lacto-ovo vegetarian, or vegan
Description The diet is high in fat, supplies adequate protein, and is low in carbohydrates. A true low-carb, ketogenic diet is one in which the percentage of calories from carbohydrates is closer to 5-10%, protein is 15-20%, and fat is 70-80% of total calories.
Rationale The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fuelling brain function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source.
Calories Calories determined from macronutrient percentages
Macronutrient Percentages 75% fat, 10% carbs, 15% protein
Carbohydrates 20-30 grams per day
<5 grams per serving
Fats Allowed: Saturated fats for cooking (cream, butter, ghee, lard, tallow, eggs, coconut oil or palm oil (use organic from sustainable agriculture), medium-chain triglycerides (MCTs), monounsaturated fatty acids (MUFA, omega 9, oleic acid), polyunsaturated fatty acids (PUFA), omega-3 and omega-6 fatty acids (ideally, this ratio should be balanced at 1:1)
Not allowed: Processed vegetable oils, margarine, hydrogenated oils, partially hydrogenated oils and other trans fats, interesterified fats (sunflower, safflower, cottonseed, canola, soybean, rapeseed, and corn oil)
Protein (meat, eggs, dairy)
  • All meat (preferably grass-fed), fish/seafood (not farmed), and poultry (preferably pastured-raised free-range)
  • Soy, natural (edamame, tofu, tempeh, miso)
  • Eggs (preferably from pastured-raised free-range poultry)
  • Cheeses (preferably from grass-fed animals)
Fiber No minimum recommendations that I could find, except 5-10 grams/day for children, but some low-carbers say at least 20 grams daily, with 1/3 or more from soluble fiber
Fruits Avocados, olives, small amounts of berries
Grains No grains or flours from grains. No bread, cereals, noodles, or pasta.
Legumes No beans, except for small amount of black soy beans
Vegetables Non-starchy vegetables, mostly leafy green
