References and Explanations

  1. There is a lot of food preparation required for this diet. Food must be generally created from scratch and there can be a lot of preparation required for meals and some people will simply not have the time
  2. The Zone diet can be a little difficult to follow and understand, especially with the number of “blocks” that are allowed each day of each nutrient (carbohydrates, fat, protein). There is a great deal of detail to understand in order to get the right balance of nutrients each day. This diet requires commitment to be able to get any results.
  3. All ingredient should be as fresh as possible, which may cost a little more than the cheaper, but definitely unhealthier alternative, take-away, processed, junk food. In addition, there are some companies who do prepare Zone diet foods, but this can also be expensive

Accessed on 10 January 2008. The author of the PCRM report notes that while low carbohydrate diets do show “modest short-term weight loss”, there have been no studies on the long term health effects of these diets. The report goes on to discuss the negative health impacts of high fat (especially high saturated fat) diets

The Cleveland Clinic’s review of the Atkins diet is to suggest that it does not contain enough nutrients and may be difficult to sustain long term, which encourages yo-yo dieting. The Cleveland Clinic is one of the major hospitals in the USA and is well-respected for their health advice and research
