Research presented by Dr McCarty explains how creatine may lower the risk of heart disease. During creatine synthesis in the liver there is a large amount of "methyl group transfers", and this chemical reaction is thought to impair the efficiency of homocysteine disposal within the body. Build up of homocysteine is thought to contribute directly to heart disease.

Exogenous creatine would inhibit the bodies need to produce homocysteine, lowering the risk of heart disease.

Blame your genetics for your poor body weight? Research suggests that you genetic makeup can be altered through changes in activity. No more reason for blaming the parents for those extra inches round the waist
