Funny you mention sand - my declaration happened when I came back from vacation and was looking at some photos. Not sure what my approach will be but I know something has to be done.
I tried lots of things before over many years, but ended up on a whole food plant based diet. That has been great! I went from obese to a BMI of 23.1 on that! Just google whole food plant based diet and lots will come up, but the McDougall diet worked best for me. They have their own forum, but they can be a bit intense
