How does Slim-Fast Diet work?

slim-fast diet

Your more than 1000 calories a day will come from three snacks (half a banana, a pear or a Slim-Fast Snack Bar, for example), two Slim-Fast meal replacements (a bar or a shake) and one 500-calorie meal you prepare. Slim-Fast is best for those people looking for a supplement to lose about 20 pounds, which should take 8 to 10 weeks; most people are likely to have trouble sticking to the regimen longer than that. Still, many dieters use Slim-Fast products as occasional meal replacements even after losing weight to make maintenance easier.

Will you lose weight?

Research withnesses that Slim-Fast is an effective way to lose weight.

  • According to a 2006 study published in the British Medical Journal comparing the effectiveness of four commercial weight loss programs in overweight and obese adults, dieters on the Slim-Fast plan lost an average of about 6 pounds over four weeks. That’s almost the same degree of initial weight loss experienced by dieters in the study who followed Weight Watchers and Eat Yourself Slim, although less than the 10 pounds lost, on average, by those following Atkins.
  • Long-term results are encouraging. In a four-year study published in Obesity Research in 2000, 100 overweight and obese people were split into two groups. One consumed 1,200 to 1,500 calories a day of regular food and the other replaced two meals a day with Slim-Fast products. Over four years, those who followed the Slim-Fast diet lost an average of 8.5 percent of their initial weight compared to 3.3 percent for the other group. If you’re overweight, losing just 5 to 10 percent of your current weight can help stave off some diseases.
  • Researchers spent four years following more than 5,000 people with type 2 diabetes; one group used meal replacement products from either Slim-Fast, Glucerna, OPTIFAST or HMR, and the other group received diabetes support and education. At the end of the study period, those assigned to the meal-replacement group had lost about 8.6 percent of their starting weight, compared to 0.7 percent for the other participants, according to findings published in Diabetes Care in 2007.
  • However, a well-thought-out review of studies (figuring out the worth, amount, or quality of)commercial weight-loss programs published in the Records of Internal Medicine in April 2015 found that results for Slim-Fast weremixed,” (even though there is the existence of) some(event(s) or object(s) that prove something) showing (almost nothing/very little) weight loss differences between those on a Slim-Fast program and others who weren‘t. (people who work to find information) said, in general, that more study is needed to (figure out the worth, amount, or quality of) the effectiveness of Slim-Fast and Internet-based commercial weight loss programs,which are gaining in (quality of being liked a lot or done a lot).
