Let's look at a concrete example of this: If you take in less than 500 calories of what you require on a daily basis, then your weight loss will be roughly one pound a week. If you increase this to bringing in less than 1,000 calories then you will lose an average of two pounds weekly. Sound good? Why does this work so well? No mater whether you are making a water-based (ice) shake or a dairy-based (2 % milk) diet shake recipe, a little container of yogurt can add a lot. Yogurt adds a nice creamy consistency to your diet shake recipes, and I wholeheartedly recommend that you try it in your favorite smoothie recipe the first chance you get. The thing is, most drinks that contain caffeine are full of calories of their own, too. Coffee, soda, and energy drinks are never going to help you lose weight, because they re filling your body up with fat and calories along with the caffeine content. Again, it s key to remember that green tea is just a little boost, in the neighborhood of an extra 70 to 80 calories burned per day. Here are some things you can do to lose 15 pounds fast. 1) Avoid foods that cause water retention, like salt. Cut back on salt and you'll begin to shed weight. 2) Eat 5-6 small meals throughout the day to keep your body's digestive process working. 3) Add foods that use more energy to digest, including meat, chicken, salmon, asparagus, cheese, carrots, squash and green beans. In addition to vast amounts of vitamin C and insulin regulation, grapefruit may also help control cholesterol, which is a powerful tool in avoiding heart disease. There is even some ongoing research that might suggest that grapefruit helps fight cancer because of its DNA-repairing abilities. Of course, let s not forget the basics. Besides, any weight loss on such programs often comes back for a number of reasons. People go off the diet in time, and dieting is only one aspect of weight loss. 'How to lose weight quickly' fads generally don't work for long. You can't lose weight as well on a fad diet as you can on a proper program that entails appropriate food selection, effective meal times and some form of exercise.
