Remember that it takes a 3500-calorie deficit to lose one pound of fat. That is, you have to either burn off 3500 calories through exercise or eat 3500 calories less than you burn in a week. Break this up into daily limits. To burn 3500 calories a week, you should aim to have a 500 calorie deficit every day. For example, you can exercise to burn 250 calories and cut 250 calories from your diet.
Experts say "The Ultimate Volumetrics Diet: Smart, Simple, Science-Based Strategies for Losing Weight and Keeping It Off," is your best guide to losing weight, maintaining long-term weight loss, and learning to eat nutritious food. Based upon research showing that low-density food will keep you fuller longer, it mitigates one of the biggest enemies of any diet: Hunger. Volumetrics is the science upon which many other popular weight loss programs are based -- including Weight Watchers and Jenny Craig. However, it requires you to know your way around the kitchen.
Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
"Protein is great for fat loss. It helps build and preserve lean muscle tissue and can increase the amount of calories you burn. It’s also a great source of energy that helps you feel fuller for longer, so you’re less tempted to snack. Good sources include chicken breast, tuna, eggs, milk and chickpeas. And if you’re finding it difficult to avoid snacks that are high in carbohydrates, try substituting them for protein shakes or bars. Remember also to opt for the lean sources of protein because some sources can be high in saturated fat."
