Myself and my family have had great success after reading and implementing Wheat Belly by Dr. Davis, and also watching Fat Head:The Director's Cut.
Just by changing my diet I was able to lose 35 lbs in about 6 months. That is *WITHOUT* exercise, not bad for being sedentary and 35y/o. There were no gimmicks, no supplements, no workout routines, no gym memberships, no HIITS, no bicycling (just joined the Mustachian Army so I have started).
Going to hop on my soapbox for just a moment here. If you have diabetes, are prediabetic, have heart issues, nephrotic syndrome, skin issues, inflammation, or any other malady that science just can't seem to fix, I highly suggest taking a look.
In true Mustachian fashion, you could get the book from the library for free. For FatHead, the original version is free on youtube.
