Losing weight without rearranging your gastrointestinal anatomy carries advantages beyond just the lack of surgical risk. The surgical community objects to the characterization of bariatric surgery as internal jaw wiring and cutting into healthy organs just to discipline people’s behavior. They’ve even renamed it “metabolic surgery,” suggesting the anatomical rearrangements cause changes in digestive hormones […]

We create more than a hundred new videos every year. They are the culmination of countless hours of research. We comb through tens of thousands of scientific papers from the peer-reviewed medical literature so busy people like you don’t have to. In 2025, I covered a wide variety of hot topics. I released an extensive

The extent of risk from bariatric weight-loss surgery may depend on the skill of the surgeon. After sleeve gastrectomy and Roux-en-Y gastric bypass, the third most common bariatric procedure is a revision to fix a previous bariatric procedure, as you can see below and at 0:16 in my video The Complications of Bariatric Weight-Loss Surgery.

Today, death rates after weight-loss surgery are considered to be “very low,” occurring in perhaps 1 in 300 to 1 in 500 patients on average. The treatment of obesity has long been stained by the snake-oil swindling of profiteers, hustlers, and quacks. Even the modern field of bariatric medicine (derived from the Greek word baros,

How do barukas, also known as baru almonds, compare with other nuts? There is a new nut on the market called baru almonds, branded as “barukas” or baru nuts. Technically, it isn’t a nut but a seed native to the Brazilian Savannah, known as the Cerrado, which is now among the most threatened ecosystems on

If the microbiome of those eating plant-based diets protects against the toxic effects of TMAO, what about swapping gut flora? “Almost 2,500 years ago, Hippocrates stated that ‘All disease begins in the gut.’” When we feed our gut bacteria right with whole plant foods, they feed us right back with beneficial compounds like butyrate, which

Is “toxic mold syndrome” a real thing? What do we do about toxic mold contamination of food? In recent years, mold has been blamed for all sorts of “vague and subjective” symptoms, but we have little scientific evidence that mold should be implicated. However, this “concept of toxic mold syndrome has permeated the public consciousness,”

The overall cost-benefit ratio for mycotoxins depends on which food is contaminated. Ochratoxin has been described as toxic to the immune system, developing fetus, kidneys, and nervous system, as well as being carcinogenic, but that is in animal studies. Ochratoxin “causes kidney toxicity in certain animal species, but there is little documented evidence of adverse

Most crops are contaminated with fungal mycotoxins, but some foods are worse than others. Oats can be thought of as “uniquely nutritious.” One route by which they improve human health is by providing prebiotics that “increase the growth of beneficial gut microbiota.” There are all manner of oats, ranging from steel-cut oats to, even better,

Ever since the days of Hippocrates, 2,400 years ago, fasting has been offered as a treatment for acute and chronic diseases, based on the observation that when people get sick they frequently lose their appetite. Along with fever, decreased food consumption is one of the most common signs of infection. Often regarded as an undesirable
