If you want to nosh on something with whipped cream, put it on fresh strawberries, not jello! Any of the "berries" are packed full of nutrients and antioxidants (blueberries, raspberries, blackberries, strawberries--just stay away from dried cranberries, b/c most of those have tons of added sugar).
For snacks:
Nuts (almonds or walnuts especially rock! But peanuts are good, too)
Pumpkin seeds
Greek yogurt (add in a few berries if you like)
Peanut butter (a couple of TB on some celery or apple slices, or toasted light wheat bread, sprinkled with cinnamon-not cinnamon sugar--just plain cinnamon)
cheese
eggs (deviled, boiled)
For meals, anything on a salad works... Make a nice green salad with romaine and some bell pepper, cucumber, olives (black or green), tomato, onion and an appropriate cheese as your basic salad. For chef, you add sliced boiled egg and ham/turkey diced or cut into pinwheels and diced monteray jack cheese or jalapeno havarti, or colby. For taco salad, you add taco meat (make your own with spices, not a "packet"), sour cream, salsa and shredded cheddar cheese. Or just add sliced grilled chicken breast meat for a grilled chicken salad. Deli rotisserie chickens work great for this!
I used to keep a container of egg salad made up in the fridge (to eat spread on single slices of toasted light wheat bread). Or make a double grilled cheese sandwich out of light bread. (Pepperidge farms light breads only have around 7 grams of carbs per slice--check the labels). Or a fried egg sandwich with 2 eggs (again, using light bread).
Munchies are fresh crunchy veg. Red bell pepper, celery, radishes, cucumber, broccoli. For side dishes, try to stick with green beans or asparagus or broccoli, or a side salad.
Main course: grilled _______ (chicken, steak, pork chops, chicken wings).
Breakfast is the easiest meal of the day: Scrambled eggs or an omelette or wrap with peppers/onions and cheese, bacon/ham, and coffee with cream only.
Oh... and for taste, Zone bars are the only "protein" bar out there that is any good. Kashi's are fantastic, but they have too many carbs if you are restricting very heavily.
