Interestingly sports supplement companies have now begun selling a cocoa extract called chocamine that is meant to provide the stimulation and health benefits of chocolate without any calories, sugars, or fats.
According to David Tolson of 1fast400.com:
"Chocamine contains numerous constituents, including methylxanthines (theobromine, caffeine, and theophylline), biogenic amines (phenylethylamine, tyramine, and according to one source, synephrine), amino acids (phenylalanine, tryptophan, tyrosine, others), minerals (with a high content of magnesium), numerous beneficial antioxidants, and possibly some non-psychoactive cannabanoid-related compounds.
The combination of these multiple ingredients produces a unique effect. Promotional literature makes many positive claims about chocamine, including increased energy, appetite suppression, increased lipolysis (fat burning), improved mood, improved concentration, increased alertness, improved physical performance, aphrodisiac properties, and health benefits."
