Why should fasts lasting longer than 24 hours and particularly for three or more days only be done under the supervision of a health professional and preferably in a live-in clinic?    Fasting for a week or two can actually interfere with the loss of body fat, as shown at the start of my videoContinue reading “The Safety of Fasting to Lose Weight “

Like the keto diet, fasting for one or two weeks can actually slow the loss of body fat rather than accelerate it.  Fasting obviously causes consistent, dramatic weight loss, as shown in the graph below and at 0:09 in my video Is Fasting Beneficial for Weight Loss?, but how do fasted individuals do long-term? SomeContinue reading “Does Fasting Benefit Weight Loss? “

For more than a century, fasting has been used as a weight-loss treatment.  I’ve talked about the benefits of caloric restriction. Well, the greatest caloric restriction is getting no calories at all. Fasting has been branded “the next big weight loss fad,” but it has a long history throughout various spiritual traditions, practiced by Moses,Continue reading “Putting the Benefits of Fasting for Weight Loss to the Test “

Peeled apples are pitted head-to-head against unpeeled apples (and spinach) in a test of artery function.  Regularly eating apples may contribute to a lower risk of dying prematurely. “Moderate apple consumption,” meaning one or two apples a week, “was associated with a 20% lower risk of all-cause mortality”—that is, dying from all causes put together—“whereasContinue reading “Flavonoid Benefits from Apple Peels “

How may we preserve bone and mass on a low-calorie diet?    One of the most consistent benefits of calorie restriction is that blood pressure improves in as little as one or two weeks. Blood pressure may even be normalized in a matter of weeks and blood pressure pills discontinued. Unfortunately, this can work aContinue reading “Any Pitfalls with Restricting Calories? “

Though a bane for dieters, a slower metabolism may actually be a good thing. We’ve known for more than a century that calorie restriction can increase the lifespan of animals, and metabolic slowdown may be the mechanism. That could be why the tortoise lives ten times longer than the hare. Rabbits can live for 10Continue reading “Restricting Calories for Longevity? “

We create more than a hundred new videos every year. They are the culmination of thousands of hours of researching, writing, editing, animating, and producing. We comb through thousands of scientific papers from the peer-reviewed medical literature so that busy people like you don’t have to! In 2023, I covered a wide variety of hotContinue reading “Top 10 NutritionFacts.org Videos of 2023”

The sugar industry responds to evidence implicating sweeteners in the obesity epidemic.    In terms of excess body fat, the “well-documented obesity epidemic may merely be the tip of the overfat iceberg.” It’s been estimated that 91 percent of adults—nine out of ten of us—and 69 percent of children in the United States are overfat,Continue reading “Sugar and Gaining Weight “

You may lose a pound of fat by skipping just 10 calories a day or as many as 55, depending on whether you’re improving food quality or restricting food quantity.    If the 3,500 calories per pound of weight loss rule is bunk, what’s the alternative? To lose a pound of fat, how many fewerContinue reading “The New Rule for Calories per Pound of Weight Loss “

What are the metabolic and behavioral adaptations that slow weight loss?    Thanks to millions of years of evolution hard-wiring us to survive scarcity, our body has compensatory survival mechanisms to defend against weight loss. When we start losing weight, we may unconsciously begin to move less as a “behavioral adaptation” to conserve energy. ThereContinue reading “Why Weight Loss Plateaus on Diets “
