Weight regulation 4: Low carbohydrate vs. low fat lifestyles for weight loss and maintenance

After my digression into the 2010 Dietary Guidelines I am resuming my series on weight regulation with a comparison of the two major methods of achieving weight loss. I was tempted to call these weight loss diets but to regulate weight in the long term it is necessary to make a lifestyle change.  One can’t […]

The 2010 Dietary Guidelines: Are they really about our health?

This post includes my testimony to the Dietary Guidelines Advisory Committee (DGAC), established by the U. S. Department of Agriculture (USDA) and U. S. Department of Health and Human Services (HHS) to update the previous (2005) Guidelines. The 2010 Guidelines make four broad recommendations: Consume fewer calories and engage in more physical activity. Switch to […]

Weight regulation part 3: What about carbohydrates?

Since the 1970s we have been told by a majority of nutrition and medical professionals that fat, especially saturated fat, is the culprit in all of our ills from obesity and cardiovascular disease to diabetes and cancer.  We have been urged to cut our fat intake down to abnormally low levels.  Since protein intake remains […]

Weight regulation part 2: Does dietary fat make us fat?

The calorie theory of weight regulation holds that in order to maintain a stable weight we must eat the same number of calories as we expend over time.  If we want to lose weight then we must eat fewer calories than we expend.  Since fat contains 9 calories per gram and carbohydrate and protein each […]

Weight regulation part 1: Why have we gotten so fat?

Americans have seen a rapid increase in weight gain and subsequent overweight and obesity over the last 30 years, and the rest of the world is catching up fast. Most of the medical and nutrition establishment maintains that it is because we eat too much and exercise too little, and most programs to fix the […]

The meat controversy—biology, ecology and ethics

First lets look at meat eating from a biological point of view. Humans are omnivores.  From the length and architecture of our digestive tracts to our nutritional requirements we maintain the best health on a diet that includes both animal and plant foods.  In fact our hunter-gatherer ancestors ate far more meat and fat as […]

Healthcare in Cuba: an interesting comparison

This post is taken from a recent article1 in Science magazine. The US trade embargo with Cuba reaches 50 years this year.  During this time food, drugs and medical supplies flowing from the US to Cuba have been severely restricted.  After the collapse of the Soviet Union in 1989, foreign aid to Cuba faltered and […]

Weston A. Price, DDS: a pioneer

Dr. Weston A. Price had a successful conventional dental career from about 1890 to the early 1900s, and devoted much of his time to the study of root canals.  This led him to the hypothesis that susceptibility to tooth decay came from a ‘disease’ or dysfunction inside the body, not from bacteria on the teeth.  […]

Lets start at the beginning…

Of course much nutritional damage begins generations before we are born, but we will leave that for another post.  As a practical starting point, what and how we feed our babies is crucially important to their future health.  In a recent analysis1, Bartick and Reinhold (2010), publishing in Pediatircs, concluded that “If 90% of US […]

How did we get here?

Important changes to our food supply have taken place over the last 150 years that have had profound effects on our health.  In this first post I will briefly cite some examples of these changes and then explore them and their health effects in more depth in subsequent blogs. Bread:  Prior to the widespread adoption […]
