Once A Week
On a low carb diet you want to be in ketosis. Cheat only once a week. For example my cheat day is on my rest day which is Sunday. Then I start training and dieting again on Monday. When you cheat, it's okay cheat all day. Wait....let me define. I don't mean sit and pig out while in front of the TV. Eat 3-4 meals instead of your 5-6 meals. Here's my example of a cheat day.
Meal 1: Scramble Eggs with cheese, meat (usually chicken breast or spicy sausage), Orange Juice, Toast with yogurt spread or hashbrowns.....Good breakfast (not the best for you though)
Meal 2: Sandwich (Egg Salad, Chicken, roast beef...etc) Low Fat Mayo, Dijon Mustard, 1 slice of cheese, on wheat, sour dough or dutch crunch, 1 small bag of potatoe chips (Kettle Chips...yum) Juice
Meal 3: Top Sirloin Steak (trimmed of fat), seasoned and BBQed, Salad, Rice or a potatoe, Coke (I can't go without my coke)
Meal 4: Desert of some kind, slice of pie, or a scoop of ice cream. Don't go overboard here.
This won't hurt you if you eat like this once a week. Just be sure you're exercising and dieting throughout the six days.
