Since my grocery week starts on Tuesday, I began my generic meal plan on that day. Notice that I did TV dinners (I use the lower calorie ones with the highest protein). One of the reasons I like doing this type of weekly menu is it gives me an outline of main dishes to go by and I can add in whatever else I need according to the meal.
Let's look at Wednesday.
Breakfast. Cereal that day can involve a high fiber cereal or a hot cereal with fruit on the side. There needs to be some kind of protein, so you can do that with real meat or even have a hard boiled egg with it.
Lunch is Sandwich day. Do I want meat? Maybe a turkey burger; how about shredded chicken BBQ sandwich? Again a small piece of fruit, some celery or carrot chips and humus or dairy dip.
Dinner is beef night so make sure you didn't eat beef for lunch! You could make a spaghetti sauce and have it over a low carb pasta. and salad on the side. But keep it lean! You could also do tacos, or burritos if using low carb wraps or even just a small steak. But along with the salad, make sure you have a hot veggie (not starchy).
Your one and only snack of the day is whatever time you prefer. You'll want to check the carb and caloric count but go whole grain and a smear of protein like peanut or almond butter or chees.
