This is caused by an imbalance between two of the main sex hormones – testosterone and oestrogen. More specifically it is the conversion, via the enzyme aromatase, of the male hormone testosterone into the female hormone oestrogen. Basically with a poor diet, ill health and a lack of exercise a lot of men convert testosterone to oestrogen and this is what causes “moobs”.
Zinc and DIM supplements will help you lose unwanted fat from your pec. Zinc helps to turn off the aromatize process and DIM clears oestrogen from the body.
