This leads to the effect that even a diet high on fats did not result in higher body weight. This fact has immediately led to the embrace of raspberry ketones by the weight loss and body building communities, despite the fact that raspberry fruits would be much healthier, containing ellagic acid, catechins, salicylic acid, and various other polyphenols, besides large quantities of Vitamin C.
