I did it kinda half-cheeked for a little last year and saw some pretty encouraging results. Now I'm going whole hog (ha, ha) this January.
A week and I've already taken my belt down a notch and my mood has elevated considerably. I guess we really are supposed to eat this way.
Breakfast: 3 hard boiled eggs, 1 sausage
Lunch: I 6oz can of salmon w/dab-o-may, 1 avocado, 4 or 5 string cheese sticks wrapped in turkey slices. 1 small apple
Dinner: I mix it up here. Either a rib-eye steak or groundbeef with veggies or half a chicken or a bunch of ribs plus a whole mess of veggies with whatever meat entree I choose. Tonight I'm going to grab a mess of oysters.
Before bed I have a glass of blueberry/coconut smoothie or tea with butter, yes butter.
Hunt, gather, repeat. Works for me.
