Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.
Yes whey: the American Journal of Clinical Nutrition found that high-protein shakes are a vital part of a weight loss plan, so don’t hold back – especially at breakfast. According to research from the University of Bath, eat 700 calories before 11am and you’ll have better blood sugar levels than those who skipped the most important meal of the day. It’s the best excuse you’ll have of sticking with a morning fry-up and avoiding a costly Starbucks lunch.
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.
