There has been a lot of talk this week about the use of very low calorie diet (VLCD) in order to treat type 2 diabetes.
The main argument is, its not sustainable and what happens after.
In terms of the sustainability question, it is not supposed to be sustainable. It is not offered as a 'lifestyle' way of eating. In this particular study, it was to see if large scale weight loss would get an individual into remission.
In this study over 86% who lost 15kg went into remission after a year and of those who lost between 10-15kg, 54% went into remission.
Surprisingly, of the group who were being treated via the current 'best' approach, only 4% went into remission.
As you can see from the amount of weight being lost, this procedure wasn't given to the 'skinny fat' part of the nation who have type 2 diabetes.
There are some things worth considering regarding a study of this kind:
1 - The individuals were on the VLCD for between 8 & 20 weeks before gradually moving into a calorie maintenance mode. This is normal for any type of calorie deficit plan, sometimes called a 'diet holiday' and heavily advised to do whatever approach you are taking to losing weight.
2 - The individuals are given support throughout the process, especially after in relation to making a long term change to their weight. Any one reading this in the media and thinking of engaging in a very low calorie diet with no support unit around them could be heading for a fall. yet, this could be said for any weight loss plan.
3 - Fast weight loss has shown in some studies to increase motivation and lead to more sustainability long term (usually described as 1 year). Emotional eating or the more extreme, disordered eating can occur with people engaging in fast or 'slow & steady' forms of weight loss. These people were treated for type 2 diabetes & losing a large amount of weight loss helped eradicate it, at least in the short term.
Saying that, if any one uses it as a justification to sell shake based multi level marketing products, they should be ashamed of themselves. Going to a seminar on how to recruit fellow sellers doesn't qualify them to work with these types of individuals
