The internet is filled with interesting information. Some of it's even true.

Never rust a fat Doctor that smokes!

I dont know if I would trust any of them. If the first solution they offer are meds for something that diet and exercise can fix that tells you all you need to know about trusting their opinion

Doc wanted the wife on a few lifetime meds. We cut carbs and increased exercise. Problems fixed number great within 6 months no meds require. Ther is no money or repeat business withna cure only contined treatments. .
