With so many diets out there it very difficult for aspiring slimmers to make a decision as to which one will work best of all.  There has been a lot of anecdotal evidence around to suggest that diets high in proteins and low in carbohydrates worked best.  Until now there has been no scientific data or even rationale to back any of this up.  We have just seen a report which appeared in the Journal of Clinical Endocrinology and Metabolism which provides some scientific evidence that might help to substantiate the anecdotal evidence.

The only known appetite stimulating hormone is something called ghrelin, which is secreted by the stomach. Levels of ghrelin increase before a meal and then subside after the ingestion of food.  The longer that ghrelin levels can be suppressed, the longer someone will go without feeling hunger pangs.  When diets containing a mixture of macronutrients of fats, proteins and carbohydrates were compared, it was revealed that the diet rich in proteins appeared to keep the ghrelin levels low for the longest period of time. Meals high in carbohydrates had the effect of suppressing ghrelin levels substantially but for a short period of time only. Fatty meals had the least impact of all on ghrelin levels which could help to explain why those on high fat diets are able to pack away so much food!
