The proportion of severely obese Americans -- those with a body mass index of 40 or more -- increased by 50 percent from 2000 to 2005, twice as fast as the increase in moderate obesity, a new study finds.
During that same period, the proportion of overweight people (BMI of 30 or more) increased by 24 percent, and the proportion of those with a BMI of 50 or more increased by 75 percent.
In the past 20 years, the largest percentage increases have occurred in the heaviest weight groups, the RAND Corporation study said.
"The proportion of people at the high end of the weight scale continues to increase at a brisk rate despite increased public attention on the risks of obesity and the increased use of drastic weight loss strategies, such as bariatric surgery," report author Roland Sturm, a RAND economist, said in a prepared statement.
The study concluded that three percent of Americans are severely obese.
Health costs for severely obese people are expected to be double that of normal weight people, while health costs for moderately obese people are expected to be 25 percent more.

I never went on a diet. I changed how I ate. No more fried foods. Sweet-
N-Low, instead of sugar. Smaller portions, and never again ate everything
on my plate.

How much you eat is the real problem.
I'm sure you already know that tortilla and potato chips aren't health foods, right? They're made with fried fats, they almost always harbor hidden toxic chemicals (acrylamides), and if they're flavored, they usually contain monosodium glutamate (MSG). This is basically a recipe for obesity.
But how does MSG cause obesity? Like aspartame, MSG is an excitotoxin, a substance that overexcites neurons to the point of cell damage and, eventually, cell death. Humans lack a blood-brain barrier in the hypothalamus, which allows excitotoxins to enter the brain and cause damage, according to Dr. Russell L. Blaylock in his book Excitotoxins. According to animal studies, MSG creates a lesion in the hypothalamus that correlates with abnormal development, including obesity, short stature and sexual reproduction problems.
