Losing 8 pounds in 3 weeks is doable even without following an exercise routine. It is generally said that fitness is achieved with 80% diet and 20% workouts. Though the fitness market is filled with lots of weight loss supplements and solutions, the only proven solution that can offer you weight loss is creating a calorie deficit. The body needs some amount of calories to function and if it does not receive the required calories it tends to steal from its fat storage. Likewise, if you consume too many calories than what is required it will store the excess as fat. To lose weight one must not go on starvation diet. Men should consume minimum of 1500 calories per day and women should consume 1200 calories per day.
Choosing programs like Nutrisystem and Medifast helps you lose up to 2lbs per week at a steady rate. When you include workouts in your routine along with dieting, you will be able to lose 8 pounds in three weeks. However, Nutrisystem claims that dieters following its Turbo 13 plan will be able to lose up to 13 lbs and 7 inches in the first month of following the diet plan. This is possible because of the Turbo Takeoff kit delivered in the first week which includes specialized weight loss foods to accelerate your weight loss process.
