As a kid I had a "sweet tooth" that was so bad my mom had to LOCK UP any candy in the house. Also I had a weight problem for years. I was never obese but I did get a big chunky. At 5' 7" then I blew up to 158! So I dieted and weighed and lost and gained until in my mid 30's that stopped and I stablized effortlessly..
Now as an adult when I have access to as much candy as I want? I don't have a sweet tooth that is worth mentioning. One bite of sweet and I'm good to go.
Weight wise. After you have cancer and survive the threat always occurs that it could come back. Rapid unexplained weight loss is an indicator. So now I weigh myself every day not because I fear gaining weight but because I fear dropping it.
Some percolating isn't it?
