A good healthy low carb diet/exercise plan would be:
Breakfast: Cook 9-grain cereal (from health food store) in water with rolled oats and wheat bran. Make a big pot of it on weekends and nuke 1/2 cup each morning. Add low fat milk or yogurt, banana, walnuts and berries. Drink hot Ovaltine. Breakfast should be your largest meal of the day to raise blood sugar level which falls during the night.
Lunch: Egg, tuna or turkey ½ sandwich on whole grain bread with bean or alfalfa sprouts and yogurt w/fruit. If you had meat loaf for dinner, bring a meat loaf sandwich on whole grain bread (NO mayo). On cold days, a squatty thermos of hot chili, split peas with ham, or beef stew.
Snacks: Fresh (not canned) fruit: banana, orange, apple, kiwi, grapes, peach, nectarine, cherries, pineapple. No chips and nothing ever from a vending machine.
Dinner: salad with white meat chicken and fresh (not canned) veggies: tomatoes, 2 kinds of lettuce, 2 kinds of shredded cabbage, shredded or sliced carrots, alfalfa or bean sprouts, zucchini, green or red peppers, hard boiled eggs, brussels sprouts, broccoli, cauliflower, tofu, cottage cheese...Instead of dressing, squeeze 1/4 tomato over it.
Or homemade bean/vegetable soups; great way to recycle leftovers.
Or grilled fish with steamed veggies.
Or omelet: In blender, whip together eggs, tofu, cottage cheese, onions, garlic powder. Cook with mushrooms, chopped tomatoes and green or red peppers.
Foods to avoid: junk food, fast foods, pastries, desserts, sugar, salty foods, syrup (even canned fruit in syrup), peanut butter, fat/grease (pork, wieners, chops, bacon, salami, pizza, chips, fries), pasta, potatoes, white bread, rice, canned veggies, ice cream, soda, chips. And of course no tobacco or alcohol in any form. Both of those add wrinkles and destroy your brain. No oil except olive and mac nut. Coffee also rots your brain.
To keep your skin clear, drink water. Veg. juice is good too. But not canned juice (too much sugar.)
Join a gym; they have all the equipment and staff to show you how to use it to get the look you want to achieve. Much cheaper than buying your own equipment. Go hiking, biking, jogging, bowling, swimming, rowing, jump rope, play tennis, badminton, volleyball, soccer, jumping jacks, lift weights, trampoline? To tone your tummy, do sit ups, push ups, pull ups, leg lifts, butt raises and crunches.
If you lack energy, take Super B complex. Try appetite suppressants.
