Are you trying to lose 10 pounds for an upcoming family event? People who are overweight can certainly try to lose 10 pounds in 3 weeks time but this is not recommended for people who are in their ideal body weight. As you will have to lose 10 pounds in a very short period, you can introduce minimal changes in your daily diet like choosing low calorie foods or whole foods and avoiding junk foods. If you have been snacking or consuming alcohol, all these have to be set aside for some time to experience the weight loss happening. When you go light on foods you will feel lighter as the days go by.

If you are not sure about losing weight on your own, you can go for weight loss programs like Nutrisystem and Medifast that claim to offer weight loss from 1lb to 2lbs per week. As you will have to lose 10 pounds within a short period of time following Nutrisystem will be very convenient as it does not demand counting calories or checking portion size on a daily basis. It delivers microwavable ready to go foods which can be carried anywhere you go. The program offers more than 150 meal choices to choose from so you will not face any dearth of meal options. Both programs have pros and cons which you can analyze and decide.

Ensure that you consume fewer calories than what you can burn in a day. To lose one pound of fat you will have to create a calorie deficit of 3500 calories per week. So, in order to shed ten pounds you will have to consume 35000 calories lesser than what you can burn. To shed this amount in three weeks, you will have to create a calorie deficit of 1666 per day. By combining diet and workout effectively you can arrive at this deficit easily.
