Obesity is multi-factorial, spectra and other stuff.

This post is a hotch-potch of thoughts that are currently whizzing around in my brain.

1) Obesity: Like just about everything in life, obesity is multi-factorial. Each factor may have only a small impact on obesity. Tackling one factor alone won't solve the problem. Every factor has to be tackled, one at a time.

So, New York City Mayor Michael Bloomberg announcing a ban on sales of sugary drinks larger than 16 ounces in restaurants, delis, sports arenas, and movie theaters won't solve the obesity problem, but it will help.

EDIT: In shops and supermarkets in the UK, tobacco products now have to be kept out of sight. I'd like to see the same thing happen to Crap-In-A-Bag/Box/Bottle (CIAB).

2) Spectra: As also mentioned in my first link, there is a spectrum of fatness in the general population which probably follows a bell distribution curve. From skinniest to fattest, there are people who are:-
Extremely skinny. Very skinny. Skinny. A bit skinny. Average. A bit fat. Fat. Very fat. Extremely fat.

If you take somebody in a category who isn't currently consuming CIAB and introduce CIAB to their diet, what happens? They move to a category to the right. Therefore, it's possible for there to be very skinny people who consume CIAB. Therefore, anybody who (or should that be Wooo?) states that the existence of very skinny people who consume CIAB is proof that Food Reward doesn't exist is wrong.

3) Other stuff: I am concerned with people overlooking postprandial (a.k.a. nonfasting) triglycerides (a.k.a. triacylglycerols a.k.a. TAGs a.k.a. TGs) after eating large amounts of fat. According to Fasting Compared With Nonfasting Triglycerides and Risk of Cardiovascular Events in Women, serum TGs 2-4 hours post-meal are very significantly associated with Cardiovascular Events (fully adjusted hazard ratio [95% confidence interval] for highest vs lowest tertiles of levels, 4.48 [1.98-10.15] [P < 0.001 for trend]).

After 4 hours post-meal, serum TGs are cleared from circulation by being burned by muscles and/or by being stored in fat cells. See Figure 3B in Extended effects of evening meal carbohydrate-to-fat ratio on fasting and postprandial substrate metabolism.
