To be fair, there are significant and many research papers that support and argue against low carb revolution, as yet wider medical community has not fully made itís mind up as to whether diets are something that is favourable in long term.
Recent research by Layman et. al., and Saris have found that low carb and high protein diets provide little benefit to dieters. Researchers found that when protein was moderately increased and carbohydrates proportionately decreased, insulin levels stabilised but no significant weight was lost. Saris in his review concluded that it is probable that a low carb, high fat diet will increase likelihood of weight gain.
While there is a lot of evidence against low carb philosophy, there is also a lot of evidence to support it. Research published in May, 2004, found that when patients on a low carb diet were compared with patients on a low fat diet, those patients who had consumed a low carb diet had a greater weight loss, decreased triglyceride levels and increased levels of HDL's - in other words their cholesterol levels had improved. To put icing on cake research has just been published to support long term efficacy of eating a low carb diet.
Despite evidence to support low carb diet plans, mainstream medicine still does not recommend them. The main points of contention with low carb, high protein diets is that they donít offer balance and variety and could prove dangerous for people at risk of heart disease. Particularly with low carb diet plans such as scarsdale diet, they are not realistic and cannot be maintained in long term causing yo-yo dieting and no one wants that !
