I'll write a primer if anyone is interested.
Paleo is essentially a lifestyle approach to diet that eliminates foods that arrived at the onset of the agricultural revolution. So, any sort of grain, most starches, pasteurized dairy, legumes, and processed foods. It revolves primarily on vegetables, lean meat (grass-fed, not low fat bs), fruits, and nuts. Also, lots of fat such as butter, olive/coconut oil.
Ketogenic diet is strictly carb-restriction to induce ketosis, which occurs through glucose fasting when ketones (derived from fat) are synthesized in the liver to be used for metabolic purposes inside of the body. Primarily a weight-loss diet.
*Read through some threads that mentioned either primal or keto and thought I'd chime in.
I've been on a paleo/primal diet for over two months, and am down 25 pounds. I spend $50/week on food, give or take a few bucks. Macro profile is about 55%F/25%P/20%C. I usually hold-out on carb intake (majority through fruit) until after workouts to replenish glycogen storages and as snacks to silence sugar cravings.
Average daily meal plan looks something like this:
Breakfast:
Black coffee
3-4eggs, scrambled with onions/mushrooms topped off with avocado and hot sauce. Sometimes I'll throw a few pieces of bacon ends on the plate, or cook up a few chicken livers.
Mid-morning snack: 1 cup of berry of my choice
Lunch:
Green salad (Spinach, Romaine Lettuce, Kale) w/ olive oil, fresh garlic, dill, and a can of tuna stirred in. Sometimes I'll roll up a ground beef patty and fry that instead and have broccoli or cauliflower instead of a salad
Post-workout or shoot around:
1 banana
Dinner:
8oz chuck eye steak w/ sauteed mushrooms on top
Vegetable blend (usually fresh broccoli/cauliflower/carrots or asparagus)
For days I'm extra hungry I have a handful of nuts at various times of the days, but they are too expensive and I'm on a budget so I keep that at a minimum.
Also, for the record, I plan on getting a lipid panel done to accurately gauge how well the diet is working internally. I'm holding off for a while longer so my cholesterol levels can stabilize, since transitionary periods in diet can produce skewed data in a lipid panel.
