Two Myths About The 3 Day Diets

We were doing a research about the 3 day diet plan and surprisingly found two myths about the three day diet associated with American Heart Association and the Cleveland Clinic that are not true.
The 3 day diet
The 3 day diet is not recommended by the American Heart Association
Let's see what the AHA has to say about the three day diet.
Phony American Heart Association Diet
AHA Recommendation
The public should be aware that there are diets that purport to be from the American Heart Association that are not. The true American Heart Association eating plan gives recommended daily servings from various food categories, not specific foods. It’s a nutritionally adequate eating plan that’s intended for a lifetime of use. It can help healthy people lose excess weight or maintain a proper body weight, but its goal is not quick weight loss. The menus provided in the American Heart Association No-Fad Diet book are also for healthy, sustainable weight loss over time.
Background
A diet supposedly from our organization has been cited several times across the United States and in Australia.
The phony diet describes a three-day menu, supposedly prescribed by the American Heart Association or by the "Heart Association." It includes vanilla ice cream, hot dogs, eggs and cheddar cheese. The diet promises a 10-pound weight loss in three days.
The bogus diet has also been cited as the Spokane Heart Diet, the Cleveland Clinic Diet and the Miami Heart Institute Diet. The poorly typed and photocopied phony diet has also been offered by mail for $2 per copy.
The phony diet is not from our organization. For years, we have recommended that Americans cut saturated fat and cholesterol by limiting egg yolks, whole-milk dairy products such as ice cream and cheddar cheese, and luncheon meats. From time to time other fad diets emphasizing other foods have been falsely attributed to the American Heart Association.
The Cleveland Clinic Three Day Diet: There is no such thing
Here is the reference from the Cleveland Clinic on the 3 day diet program.
Q: I've heard that Cleveland Clinic has a 3-day diet available for weight loss, cleansing, reducing cholesterol and increasing energy. Is this true?
A: Despite a few sites on the World Wide Web, there is no Cleveland Clinic Diet, nor a Cleveland Clinic grapefruit diet. It truly is folklore--started several years ago. We all wish that weight loss and other health benefits could occur with simply making three days worth of dietary change. But severely restricting your calories and including/excluding specific foods from the diet is not the way to long-term, sustained weight loss and health benefits.
The good news is that weight loss, improved heart health and increased vitality can be realized when proper diet and lifestyle changes occur over the long-term. In fact, the Cleveland Clinic supports a healthy heart-minded Mediterranean diet to achieve both a healthy body weight and healthy heart. The traditional Mediterranean dietary practices that we support include eating minimally processed, plant-based foods like fruits, vegetables, whole grains, legumes, and unsaturated fats like olives, olive oil, nuts, and seeds. In the Mediterranean way of eating, high fatty cuts of meat and dairy are minimized, and omega-3 rich fish is encouraged.
Weight loss success and a healthy heart depend upon a well-balanced diet with a variety of healthy food choices that fits in with your tastes. And don't forget to monitor your portion sizes and include regular physical activity to help you achieve your goals.
For specific interventions that may help you achieve a healthy lifestyle, you may make an appointment with a Heart and Vascular Institute Preventive Cardiology dietitian, as well as obtain a full preventive evaluation by calling 800.223.2273, ext. 49353 or locally 216.445.9353.
Therefore, please from now on when you read about 3 day diet plans being associated with the Cleveland Clinic and the American Heart Association please know that there is no such thing or recommendation from these respected organizations.

Weight Loss Study Compares Black Women From US, Nigeria

Washington Examiner nutrition columnist Mark Sisson on Wednesday examined a recent study looking at the effect of diet and exercise on weight among black women.
For the study, which was published in the journal Obesity, researchers led by the Loyola University Health System compared the weight, activity levels and diets of a group of black women living in Chicago with a group of women living in rural Nigeria. The average weight of women in the Chicago group was 184 pounds and women in the Nigeria group weighed 124 pounds on average.
According to Sisson, the "researchers found no discernable difference in calories burned due to physical activity between the two groups of women," but an analysis of their diets concluded that "diet is a more likely explanation for why women in the Chicago cohort weigh more than their Nigerian counterparts."
The Nigerian women typically followed a diet rich in fiber and carbohydrates; the Chicago women, however, had diets that were high in fat and processed foods, according to Sisson. Researchers suggested that diet might be more important than exercise when it comes to weight loss, according to Sisson. Researchers also said that weight loss might not be as easy without dietary changes.
He writes, "While these findings are certainly interesting," it is "important to remember that exercise has more benefits than a smaller number on the scale," such as lower blood pressure and cholesterol levels, improved mental health and mood, and a reduced risk of several chronic conditions. He concludes that the "key to good health is to follow a nutritious diet and hit the gym on a regular basis" (Sisson, Washington Examiner, 1/14).

Discovering Drug That Cuts Appetite, Boosts Energy

In a major advance in obesity and diabetes research, Yale School of Medicine scientists have found that reducing levels of a key enzyme in the brain decreased appetites and increased energy levels.
Reductions in the levels of the enzyme prolylcarboxypeptidase (PRCP) led to weight loss and a decreased risk of type 2 diabetes in mice, according to research published in the August issue of The Journal of Clinical Investigation. The team found that PRCP is located in the hypothalamus and regulates levels of a peptide known for inhibiting food intake and stimulating energy expenditure — the alpha-melanocyte stimulating hormone (alpha-MSH). Researchers found that blocking the PRCP enzyme keeps the alpha-MSH peptides from being degraded, resulting in higher levels of alpha-MSH and decreased appetite.
"Our research provides the first evidence that breaking down molecules in the brain that regulate metabolism is an important component of weight control," said senior author Sabrina Diano, associate professor in the Departments of Obstetrics, Gynecology and Reproductive Sciences, and Neurobiology. "Our findings provide a possible new target for the development of drugs to control metabolic disorders such as obesity and type 2 diabetes."
Diano and her team conducted the study in congenic mice that were naturally lean and later in mice that had PRCP removed. Animals without the PRCP enzyme were leaner and ate less food. They also had higher levels of alpha-MSH in the hypothalamus compared to control animals. The mice were put on a diet of 45 percent fat—the equivalent of eating fast food everyday—and even with this high fat diet, they did not gain as much weight as control animals on a regular diet.
