F--- low carbs diets!
I'm not an expert on nutrition, but I play one on TV (err, I mean, I studied biochem at one point in the last millennium).
Here's a pretty non-controversial hypothesis: if you have high triglycerides in your blood stream, your carb intake is probably responsible for much of your rotundity. A simple blood test will tell you whether it's worth checking into. Mine were outrageously high for years. I cut out sugar and starch (including pasta, starchy veggies, etc) for a few weeks, and my triglycerides fell to a normal level, and I dropped about 10 lbs.
It's all about liver function and insulin. Your body cranks out insulin in response to high blood sugar. This works fine when you're a youngster, but if you have continuously high blood sugar (i.e., consume lots of carbs), eventually your cells are awash in insulin, and they become resistent (you start losing insulin receptor sites).
Eventually, this can lead to diabetes, but before you get there, you just start converting the carbs to triglycerides all day, which eventually get stored as fat after they're done blocking your arteries.
Aren't you glad the concept of "off-topic" doesn't exist here?
