4 Weight-Loss Myths
Believe the myths, and despair?

The hypothesis: a slow carb diet with intermittent fasting, along with continuing to work for greater integration of exercise into my daily life, will help me lose weight and improve my still-too-high blood sugar. This is the third experiment of a 13 weeks duration, in an ongoing series. Follow my daily updates at Facebook and join me on Fitocracy to follow my progress there, of which there will be some. Honest.
13 Weeks: Season 3, Week 3
I’ve been personally interested in weight loss and associated things pretty much my entire life. Long-time readers will remember me mentioning being insulted about my weight — told I was repulsive, in fact — when I was seven or eight. I first started actively dieting, hoping to lose weight and not be repulsive, when I was about 12, and immediately ran into trouble with it. After a certain length of time, even strictly following a 1200 kcal a day diet, I’d stop losing weight.
Since this was well-known to be impossible, it must have been that I was cheating on the diet. I knew I wasn’t, but who’s going to believe a 12 year old?
Fast forward to when I was working on my PhD at Duke Medical School. By this time I was considerably more sophisticated — well, except emotionally, I still felt basically that I was repulsive — and I had started reading seriously about weight regulation. I discovered that a whole lot of things I’d been told were absolutely certain, weren’t. Many of those things are still generally believed, and I think they keep people from doing what is useful, get them to do a lot of things that aren’t particularly useful, and frankly cause many people to despair.
Myth #1: The “Ideal” Weight Is Healthiest.
This one has made recent news. Our idea of what is an ideal weight comes originally from studies done by life insurance companies. The insurance company actuaries spend their time trying to decide how much to charge for an insurance policy, which is essentially a bet: you are betting the insurance company that you will die young, and the insurance company bets you will live to a ripe old age. (I’ve explained the basic math of insurance on PJM before.) So insurance companies, primarily MetLife, did studies in the ’50s and computed ideal weights from them.
