Dr. Lustig explains why we are fat

So…why are we fat?

The incidence of overweight and obese individuals shown in the NHANES surveys has a linear relationship to fructose consumption in the U.S. According to the USDA?s data, total sugar and fructose consumption started to increase sharply in 1985 and reached a peak in 1999, which is congruent with the incidence of obesity. During 2000 through 2005 we see a slight drop in total sugar and fructose consumption, which is consistent with the leveling off of obesity rates during that same period. This drop in sugar, adds up to 10lbs of total sugar with fructose contributing 6 of those lbs.

Even more compelling, the USDA?s data in reveals total sugar consumption from 1970 to 1999 increased 26%, which at first glance doesn?t seem like much. Also note that from 1970 to 1983 total sugar consumption did not increase while obesity rates did. This would lead one to infer that sugar is not a major contributing factor to our expanding waist-lines. However, take another look. While total sugar consumption did not increase from 1970 to 1983, fructose consumption tripled. More-over, between 1970 and 1999 with only a 26% increase in total sugar consumption, fructose consumption increased 425%.

In the below video Dr. Lustig puts the kibosh on the positive reputation fructose has been allowed to hold even in the face of mounds of evidence pointing to the contrary.


Lose fat with coconuts

Unless you’ve been in a vacuum, you’re aware that the U.S. has a little bit of a weight problem. As a matter of fact, if you’re born in this country your chance of being overweight is greater than 60 percent. One of the many great benefits of coconut oil, specifically the medium chain fatty acids (MCFA) it contains, is its ability to increase energy expenditure. In other words, it increases your metabolism.

Unlike long chain fatty acids (LCFA’s), MCFA’s are processed very easily by the body. When they are consumed, MCFA’s are absorbed directly into the blood stream from the small intestines and go right to the liver. Once in the liver, they are easily burned as fuel. Because of their size and the ease in which they are processed, MCFA’s are not readily stored as fat. On the contrary, because of their size, LCFA’s are not as efficiently processed and the body prefers to store them in fat cells.

MCFA’s metabolism boosting effects have been known for decades and are heavily documented through research:

In a study, researchers compared the thermogenic effect between MCFA’s and LCFA’s after single meals. The meals of 400 calories consisted entirely of either MCFA’s or LCFA’s. The thermogenic effect of MCFA’s over six hours was three times greater than that of LCFA’s. Researchers concluded that as long as the calorie level remained constant, substituting MCFA’s for LCFA’s would result in weight loss. [1]

Farmers found that when they fed their livestock feed that contained polyunsaturated oils like soy and corn oil, animals readily gained weight. However, when they used feed that incorporated coconut oil, the animals got leaner. The main reason for this is that polyunsaturated fats suppress thyroid function, which decreases the animal’s metabolic rate. Soy oils are the worst offenders because of the goitrogens (anti thyroid substances) they contain. [2] This is what happens to us. Is it any wonder the obesity epidemic is so bad when our consumption of vegetable fats has increased more than 400%? [3]

Researchers at Vanderbilt University compared the thermogenic effect of liquid diets containing 40 percent of fat as either MCFA’s or LCFA’s. All subjects were studied for one week on each diet in a double blind, cross-over design. Resting metabolic rate did not change during the week. The thermogenic response to MCFA’s was roughly twice that of the LCFA’s. [4]

A study was published last year conducted by researchers at McGill University to evaluate existing data describing the effects of MCFA’s on energy expenditure and to determine their efficacy as agents in the treatment of obesity. They reported that several different studies have shown weight loss equivalent to 12 to 36 pounds a year simply by changing the types of oils used in everyday cooking and food preparation. Animal and human studies have shown greater energy expenditure, less body weight gain, and decreased size of fatty deposits when using MCFA’s as opposed to LCFA’s. [5]

Sources of Coconut oil:
Only use organic virgin coconut oil. I am currently using Tropical Traditions Virgin Coconut Oil. This oil is truly unrefined and made from organic coconuts. It contains a very high lauric acid content between 50 and 57 percent. I use between two and four tablespoons per day, which is what is recommended.

Did you know…

In my latest “Did you know…” column I discuss more sunshine vitamin benefits (below); the link between obesity and bad sex; the relationship of soy foods and low sperm counts; decreasing your risk of infection in the gym, and cardiologist’s admissions.

… there are more than 800 scientific articles showing the effects of vitamin D on cancer? Some researchers point out that increasing vitamin D levels world-wide could prevent numerous diseases that claim nearly 1 million lives per year. Vitamin D, or the ?sunshine vitamin,? is really not a vitamin, but a powerful hormone precursor that has an enormous influence on our bodies. Receptors that respond to the vitamin have been found in almost every human cell. Researchers have found that vitamin D has a direct influence on 3,000 of your 30,000 genes.

The health benefits of optimal vitamin D levels are absolutely extraordinary. The main reason it?s not more widely promoted is there is no money to be made from it by the medical and pharmaceutical industries.
