There are endless ways to do interval training. One simple example: First, warm up for 10 to 15 minutes. Then, pick up your effort so you’re working hard (a nine on a scale of one to 10—you should be breathing hard, but not gasping) for 30 to 60 seconds. Go easy for one minute. Repeat for a total of 5 times, and the cool down for two to three minutes.
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.
