The Fast Diet from the UK — Seriously??

We all want something for nothing. As Mother always use to say — you can’t get something for nothing.  So.. In the UK the their is a book call The Fast Diet.  The jest of the book is you can eat whatever you want, but still lose weight, and even live longer as long as you employ “intermittent fasting.” The book claims that you can eat whatever you want for 5 days and then fast for 2 back to back days having no more than 500 calories for women and 600 calories for men.
In their book, Dr. Michael Mosley and Mimi Spencer do a fine job building a case for intermittent fasting as a method for better weight-control, improved health, and even longer life. For example, they review the research produced by nutritionist Krista Varady of University of Illinois at Chicago, who was the principal investigator for UIC’s study evaluating Isagenix products. They also discuss the findings of Dr. Valter Longo and Mark Mattson in rodents that show that calorie restriction and intermittent fasting can potentially protect the brain and increase lifespan.
However, the weight-loss plan has had critics putting up their warning signals and for good reason:

  • Eating whatever you want (and as much as you want) has its consequences. One of the biggest negatives is the diet-vs-cleansingendorsement to eat without restraint for five days of the week. The book does provide readers with some healthy eating guidelines, but with the main attraction being Eat anything you want!, Let’s get real we know how the average person will take that, they will  grossly overeat greasy hamburgers, French fries, and sugary sodas as much as possible! Even two days of intermittent fasting can’t undo a lifetime of eating like that.
  • Another problem is potential muscle loss. During intermittent fasting your body it may cause your body to go into a catabolic  state.  Catabolism is fine for the breakdown of fat, but if calorie-deficient bouts are not followed up with the right type of muscle-building protein in the right amount, the result can be breakdown of muscle. Studies have found that during weight loss, a diet higher in quality protein preserves muscle mass more than a diet higher in carbohydrate (2). Research has also found that protein from dairy, such as whey, may be the superior protein for increased fat loss and muscle retention during weight loss (3).
  • Not getting enough macro nutrients . Americans already eat too much, yet do not receive adequate amounts of macronutrients (vitamins and minerals) from their foods for optimal health. Mainly, this is because too many people don’t eat enough fruits and vegetables or may not know how to properly choose foods for adequate amounts of macronutrients. Even those who think they know what foods to eat in combination for better health haven’t fared well in achieving weight loss and improved health. One study compared weight loss groups consuming either fresh, healthy foods for the majority of their diet or nutrient-rich meal replacement shakes and found that meal replacement shakes resulted in more weight loss, better improvement to health biomarkers, and better adherence based on the convenience of the shakes (4).

So, how can you take advantage of the benefits of intermittent fasting without the drawbacks of the Fasting Diet approach that include eating too much, losing muscle, and not getting enough vitamins and minerals? Look to Isagenix for the perfect program that takes the guesswork out of intermittent fasting and how to do it right.

What you get with Isagenix is intermittent fasting fully prepped for as Cleanse Days, which are part of a fully guided system that won’t leave you eating everything in sight one day followed by wanting to eat your arm off the next. An Isagenix system means moderate calorie control on Shake Days and appropriate fasting with nutritional support on Cleanse Days.

The Isagenix system, unlike The Fast Diet, is also backed by clinical data showing that it leads to healthy weight loss, fat loss (without the muscle loss, especially if exercise is included), and better cardiovascular health. The end result is curbed food cravings, successful weight loss and maintenance, preservation of muscle mass, and finally, a long-term lifestyle that will get you healthier than ever before.

  1. Caloric restriction may have its evolutionary roots as a survival mechanism, allowing species to survive on scraps when food is scarce in order to continue to reproduce. But that restriction only has lasting positive effects if the overall diet is a balanced one, which may not always be the case in conditions of famine. (That also explains why anorexia is so unhealthy: people who starve themselves become malnourished). It’s possible the strategy developed as a way to protect species from consuming toxic plants or foods, when it wasn’t always obvious which sources were verboten.;’:-
