Frontiers In Nutrition in July, 2022, published “Fad Diets: Facts and Fiction.” Thank you, FIN, for making it available at no cost. The authors are based in Pakistan and Romania. They attempted to summarize the literature on popular fad diets. I am shocked that they included the Mediterranean diet as a fad diet. Read the article and 134 references then form your own opinion. Some snippets:

Regarding the Atkins Diet: “AD provides several benefits including weight reduction and cardio-metabolic health improvement, but limited evidence exists as compliance is the major barrier to this dietary regimen. Strict supervision by health professionals is advised as adverse metabolic sequelae can result from this type of diet.”

The Paleolithic Diet: “More randomized trials need to be done to highlight the consequences of such diets that eliminate one or more food groups. PD is powerful at advancing weight reduction for the time being but its efficacy in cardiovascular events is not well established as limited long-term data is available.”

Mediterranean Diet: “No evidence of adverse effects associated with MD is available in the literature. Rather, MD has preventive and therapeutic potential for many chronic diseases. It is highly suitable for the general public for the prevention of micronutrient deficiencies and specifically for those patients who are more health-conscious than just weight loss oriented.”

Vegetarian Diet: “No evidence of adverse effects associated with MD is available in the literature. Rather, MD has preventive and therapeutic potential for many chronic diseases. It is highly suitable for the general public for the prevention of micronutrient deficiencies and specifically for those patients who are more health-conscious than just weight loss oriented.”

Intermittent Fasting: “Despite the effectiveness of IF in weight loss as indicated by several studies, the current evidence is non-conclusive. The prime focus of available literature is weight loss but little is known about its sustainability and long-term health effects. More long-term trials should be conducted to draw a clear conclusion.”

Detox Diets: “Energy-restricted DDs are capable of short-term weight loss. But still, there is a high likelihood of health risks from detox products because of their nutritional inadequacy. As no convincing evidence exists in this domain so such diets and products need to be discouraged by health professionals and must be subjected to regulatory review and monitoring.”

Ketogenic Diet: difficult to summarize.

From CNN:

It’s a winning streak that just won’t quit. For the fifth year in a row, the Mediterranean diet was first across the finish line in the annual race for best diet, according to ratings announced Tuesday by U.S. News & World Report.

Coming in a close second, in a tie: The DASH diet, which stands for dietary approaches to stop hypertension and emphasizes reducing salt intake; and the flexitarian diet, which encourages being a vegetarian most of the time — but is flexible enough to allow a burger once in a while

All three of these diets reduce or eliminate processed foods, and stress packing your plate with fruits, vegetables, beans, lentils, whole grains, nuts and seeds.

I’m surprised they ranked Atkins as the “Best Fast Weight-Loss Diet.” Looks like we’re getting over our collective phobia about saturated fat. “Keto Diet” ranked #4 in that category.

Now that you’ve blown your New Year’s weight-loss resolution, resolve to do better and try one of my diets! February 1 is a good start date.

Semaglutide was originally FDA-approved as a treatment for type 2 diabetes. The drug mimics a natural hormone called glucagon-like peptide-1 (GLP-1). It will be sold under the trade name Wegovy. The dose of this injectable medication must be increased gradually over 16 to 20 weeks to 2.4 mg once weekly to reduce gastrointestinal side effects. I have no idea how much it will cost. From the FDA:

Today, the U.S. Food and Drug Administration approved Wegovy (semaglutide) injection (2.4 mg once weekly) for chronic weight management in adults with obesity or overweight with at least one weight-related condition (such as high blood pressure, type 2 diabetes, or high cholesterol), for use in addition to a reduced calorie diet and increased physical activity. This under-the-skin injection is the first approved drug for chronic weight management in adults with general obesity or overweight since 2014. The drug is indicated for chronic weight management in patients with a body mass index (BMI) of 27 kg/m2 or greater who have at least one weight-related ailment or in patients with a BMI of 30 kg/m2 or greater.

The most common side effects of semaglutide include nausea, diarrhea, vomiting, constipation, abdominal (stomach) pain, headache, fatigue, dyspepsia (indigestion), dizziness, abdominal distension, eructation (belching), hypoglycemia (low blood sugar) in patients with type 2 diabetes, flatulence (gas buildup), gastroenteritis (an intestinal infection) and gastroesophageal reflux disease (a type of digestive disorder).
