40/40/20 works somewhat when eating an omnivorous diet. Meat-heads still gain fat.
80%+ from cabs, max 10% from protein and max 10% from fat. Try it. You'll be able to eat all the fruit you want without worrying about the myth that too much potassium from natural sources causes heart attacks. Potassium isn't toxic at the doses found in fruit, its impossible to overdose unless the vains are full of fat. I would advise to clean up your vains from all that animal fat with natural antioxidants like vegetables, lettuce, and carrot juice before going crazy with the lovely fruits.
The change will take awhile until your body gets cleaned up, so don't give up.
Mothers milk has 6% protein. Tell that to your meat-eating boyfriend.
