Hi, Im not fat, i can see some of my upper abs, i workout - bodyweight workouts at home - and workouts at the gym, i found this diet, i never tried diets, and this will be my first and last one but can it get me a six pack or let me lose body fat?

Vegetables to choose from: artichoke, asparagus, beets, bok choy, broccoli, brussel sprouts, cabbage, carrots, cauliflower, celery, green beans, kale, mushrooms, okra, onions, peppers, spinach, squash, tomato. These can be eaten raw, steamed, or in a big salad drizzled with a little olive oil and/or balsamic vinegar.

DAY 1: At 8am, noon, 4pm, and 8pm eat as much of any vegetable as you want, in any combination. You don’t have to eat at those exact times, but spread out the four meals as evenly as possible. Drink 100 ounces of water.

DAYS 2-4: Eat vegetables at the same four times each day but add in 20 grams of protein from fish, chicken, lean beef, turkey, eggs or seafood at 8am and 4pm meals. This equates to 3-4 ounces of fish, chicken, lean beef, turkey, or seafood or 3-4 whole eggs at those two meals. Drink 100 ounces of water.

DAYS 5-7: At 8am, noon, 4pm, and 8pm eat vegetables in any combination and quantity and have 20 grams of protein (3-4 ounces) from fish, chicken, lean beef, turkey, seafood or 3-4 eggs at each meal. Drink 100 ounces of water.
