Jillian Michaels is a fitness expert and a trainer on the television shows, "The Biggest Loser" and "Losing it with Jillian." She is also an author, blogger, life coach and creator of several fitness DVDs and video games. One of her DVDs, "30 Day Shred," claims to help customers lose up to 20 pounds in 30 days. This is achieved by doing one of three 20-minute workouts a day, with each workout increasing in intensity. Of course, sometimes people need to lose weight faster. If you have 10 pounds to lose in two weeks, you can do it using this video and following a healthy diet.
Workout with Jillian's video twice a day. People on the 30 day program are told to do the level one workout for ten days, then the level two workout for ten days and then finally, the level three workout for ten days. By doing two workouts a day---one in the morning and one at night---for two weeks, you can get through 28 of the 30 workouts, thereby maximizing your weight loss benefits.
Seize any opportunity to get in an extra few minutes of physical activity. For example, if you have the option to take the stairs or the elevator, take the stairs. If you usually walk your dog, run instead.
Eat fewer calories. This is crucial. If you eat more calories than you burn, you will gain weight. Over the course of the next two weeks, cut out white breads and pastas, potato chips and sugary snacks, soda, creams, and fried food. To determine how many calories you should eat to lose weight, visit a website that calculates your daily calorie needs, such as "Freedieting," "ExRx" or "Straight Health." These websites will tell you how many calories you need---based on your height, weight, sex, age and activity level---to maintain your weight. From there, try to eat 100 calories less per day.
Eat small meals every four hours instead of eating three large meals a day. According to Jillian, after four hours without food, your body goes into starvation mode and your metabolism shuts down. By eating every four hours, you can keep your metabolism burning calories all day.
