Though out the world, incidences of obesity and diabetes is increasing at an alarming rate.  Obesity levels in the United States remained relatively constant from the early 1960's through 1980, at 12% to 14% of the population; over the next twenty-five years, coincident with the official recommendations to eat less fat and so more carbohydrates, it surged to over 30 percent.  By 2004, one in three Americans was considered clinically obese. 

So why this drastic change?  Here is one anecdotal piece to the puzzle as to why our society believes in a low-fat, high carb diet.

The Eisenhower Paradox
PRESIDENT DWIGHT D. EISENHOWER SUFFERED his first heart attack at the age of sixty-four.
It took place in Denver, Colorado, where he kept a second home. It may have started on Friday, September 23, 1955. Eisenhower had spent that morning playing golf and lunched on a hamburger with onions, which gave him what appeared to be indigestion. He was asleep by nine-thirty at night but awoke five hours later with "increasingly severe low substernal nonradiating pain," as described by Dr. Howard Snyder, his personal physician, who arrived on the scene and injected Eisenhower with two doses of morphine. When it was clear by Saturday afternoon that his condition hadn't improved, he was taken to the hospital. By midday Sunday, Dr. Paul Dudley White, the world-renowned Harvard cardiologist, had been flown in to consult.

For most Americans, Eisenhower's heart attack constituted a learning experience on coronary heart disease. At a press conference that Monday morning, Dr. White gave a lucid and authoritative description of the disease itself. Over the next six weeks, twice-daily press conferences were held on the president's condition. By the time Eisenhower's health had returned, Americans, particularly middle-aged men, had learned to attend to their cholesterol and the fat in their diets. Eisenhower had learned the same lesson, albeit with counterintuitive results.

Eisenhower was assuredly among the best-chronicled heart-attack survivors in history. We know that he had no family history of heart disease, and no obvious risk factors after he quit smoking in 1949. He exercised regularly; his weight remained close to the 172 pounds considered optimal for his height. His blood pressure was only occasionally elevated. His cholesterol was below normal: his last measurement before the attack, according to George Mann, who worked with White at Harvard, was 165 mg/dl (milligrams/deciliter), a level that heart-disease specialists today consider safe.

After his heart attack, Eisenhower dieted religiously and had his cholesterol measured ten times a year. He ate little fat and less cholesterol; his meals were cooked in either soybean oil or a newly developed polyunsaturated margarine, which appeared on the market in 1958 as a nutritional palliative for high cholesterol.

The more Eisenhower dieted, however, the greater his frustration (meticulously documented by Dr. Snyder). In November 1958, when the president's weight had floated upward to 176, he renounced his breakfast of oatmeal and skimmed milk and switched to melba toast and fruit. When his weight remained high, he renounced breakfast altogether. Snyder was mystified how a man could eat so little, exercise regularly, and not lose weight. In March 1959, Eisenhower read about a group of middle-aged New Yorkers attempting to lower their cholesterol by renouncing butter, margarine, lard, and cream and replacing them with corn oil. Eisenhower did the same. His cholesterol continued to rise. Eisenhower managed to stabilize his weight, but not happily. "He eats nothing for breakfast, nothing for lunch, and therefore is irritable during the noon hour," Snyder wrote in February 1960.

By April 1960, Snyder was lying to Eisenhower about his cholesterol. "He was fussing like the devil about cholesterol," Snyder wrote. "I told him it was 217 on yesterday's [test] (actually it was 223). He has eaten only one egg in the last four weeks; only one piece of cheese. For breakfast he has skim milk, fruit and Sanka. Lunch is practically without cholesterol, unless it would be a piece of cold meat occasionally." Eisenhower's last cholesterol test as president came January 19, 1961, his final day in office. "I told him that the cholesterol was 209," Snyder noted, "when it actually was 259," a level that physicians would come to consider dangerously high.

Eisenhower's cholesterol hit 259 just six days after University of Minnesota physiologist Ancel Keys made the cover of Time magazine, championing precisely the kind of supposedly heart-healthy diet on which Eisenhower had been losing his battle with cholesterol for five years. It was two weeks later that the American Heart Association—prompted by Keys's force of will—published its first official endorsement of low-fat, low-cholesterol diets as a means to prevent heart disease. Only on such a diet, Keys insisted, could we lower our cholesterol and our weight and forestall a premature death. "People should know the facts," Keys told Time. "Then if they want to eat themselves to death, let them."

Scientists justifiably dislike anecdotal evidence—the experience of a single individual like Eisenhower. Nonetheless, such cases can raise interesting issues. Eisenhower died of heart disease in 1969, age seventy-eight. By then, he'd had another half-dozen heart attacks or, technically speaking, myocardial infarction's. Whether his diet extended his life will never be known. It certainly didn't lower his cholesterol, and so Eisenhower's experience raises important questions.

Establishing the dangers of cholesterol in our blood and the benefits of low-fat diets has always been portrayed as a struggle between science and corporate interests. And although it's true that corporate interests have been potent forces in the public debates over the definition of a healthy diet, the essence of the diet-heart controversy has always been scientific. It took the AHA ten years to give public support to Keys's hypothesis that heart disease was caused by dietary fat, and closer to thirty years for the rest of the world to follow. There was a time lag because the evidence in support of the hypothesis was ambiguous, and the researchers in the field adamantly disagreed about how to interpret it.

From the inception of the diet-heart hypothesis in the early 1950s, those who argued that dietary fat caused heart disease accumulated the evidential equivalent of a mythology to support their belief. These myths are still passed on faithfully to the present day. Two in particular provided the foundation on which the national policy of low-fat diets was constructed. One was Paul Dudley White's declaration that a "great epidemic" of heart disease had ravaged the country since World War II. The other could be called the story of the changing American diet. Together they told of how a nation turned away from cereals and grains to fat and red meat and paid the price in heart disease. The facts did not support these claims, but the myths served a purpose, and so they remained unquestioned.
