Metabolism patches

[Shitwithsugar]

Have just returned from a few days away and I got chatting to a lady who uses the metabolism patches for weight loss. She claims that she has lost a stone since new year. She was saying she is only eating healthy food.
Does anyone have experience of these patches or too good to be true.

They are a con, usually they contain a very small amount of berberine which is not enough to do anything, even if berberine was solidly shown to affect your metabolism.

This woman might have lost a stone since the New Year by eating healthy food but these patches are not responsible, other than as a placebo.
