The weight management subject will require a series of missives to address. This, the first is when to recognize you have something that should weigh on you.
This subject may not be popular in the USA, especially in those more senior, but like taxes, it must be dealt with properly or the consequences can be catastrophic. Most people are in denial believing that weight gain just is inevitable in their senior years. NOT SO. My Grandparents and Mom were in rest homes and there were almost no residents that were obese.
