A perfect body is an important aspect in everyone's life. In the quest to lose weight, people tend to practice various weight loss diets and all sorts of weight loss methods to lose weight quickly. One such crash weight loss diet is the Slim-Fast diet. According to the maker of the diet, you may lose about 10% of your total body weight in the first six months of the diet plan'. What is Slim-Fast? Slim-Fast is a brand of weight loss meal replacement shakes and other dietary supplements like bars and powders. It is popularly sold in the US, Canada, UK, Germany, France, Iceland, Ireland, and South America. It is one of the popular weight loss diet products in use since the last two decades. It promotes healthy weight loss through reduction in the calorie count. The meal replacement products that are available for this brand bear lesser calories than our regular diets. There are only 200 calories in the Slim-Fast meal instead of approximate 500 calories that are present in one meal that we consume. It also means that if you replace two meals with Slim-Fast, then you are cutting back on 600 calories a day. It fills out 1/3 of the daily nutritional needs of a person and keeps you feeling full for four hours. This is the reason why this diet has gained so much popularity. How Does it Work? Slim Fast is a four-step diet plan that works on the formula - Replace, Combine, Diet, and Snack. This plan is also called 3-2-1 diet plan, since it includes three 100-calorie healthy snacks, 2 Slim Fast meals, and one 500-calorie healthy meal a day. You need to consume healthy low-carb snacks and they need to be combined with a 500 calorie meal which includes - ¼ plate of lean protein + ¼ plate of starch + ½ plate of vegetables. The best thing about this diet is that no foods are forbidden in it. However, you may need to limit the amount of foods that you consume. There are a few positive points of this weight loss diet. For instance, there is a realistic weight loss target for you, which is to lose 10% body weight in the first 6 months of the diet. Along with this diet, you are advised a workout session of about 30 minutes everyday. According to this plan, you consume only 1,200 calories a day plus the 30 minutes of exercise. Does Slim Fast Really Work? According to some studies, Slim-Fast is not a quick weight loss diet and one needs to follow it patiently to experience its positive results. Many dieters claim that they successfully lost a significant amount of weight, but as soon as they returned to a regular diet, they began to put on weight. It may be the case with people who binge on fatty foods and calorie-loaded meals, as soon as they quit the diet. But, if you continue having a balanced diet of low-fat foods and exercise regularly, then you may still maintain your weight loss target. According to many dieters, this diet is one of the most effortless weight loss diets and hence, you can easily maintain it. However, according to some people, the meal replacements are very low on calories and that may put you at the risk of unhealthiness. Also, its low-calorie, high-fiber nature may fluctuate the blood sugar levels to a great deal. As aforementioned, Slim-Fast controls the food intake and makes you feel full for a longer period of time. But, if the daily calorie consumption of a person is higher, then this diet might prove to be useless for him. So, the answer may be given in both an affirmation and a negation. However, rather than relying on such crash diets, a well planned routine that includes a healthy diet and regular weight loss exercise may prove more beneficial.
