Journalist Gary Taubes created a stir in 2007 with his impressive but daunting 640-page tome Good Calories, Bad Calories. Now he has written a shorter, more accessible book Why We Get Fat: And What to Do About It to take his message to a wider audience. His basic thesis is that:
– The calories-in/calories-out model is wrong.
– Carbohydrates are the cause of obesity and are also important causes of heart disease, type 2 diabetes, cancer, Alzheimer’s, and most of the so-called diseases of civilization.
– A low-fat diet is not healthy.
– A low-carb diet is essential both for weight loss and for health.
– Dieters can satisfy their hunger pangs and eat as much as they want and still lose weight as long as they restrict carbohydrates.
He supports his thesis with data from the scientific literature and with persuasive theoretical arguments about insulin, blood sugar levels, glycemic index, insulin resistance, fat storage, inflammation, the metabolic syndrome, and other details of metabolism. Many readers will come away convinced that all we need to do to eliminate obesity, heart disease and many other diseases is to get people to limit carbohydrates in their diet. I’m not convinced, because I can see some flaws in his reasoning. Read more »

As part of the new healthcare legislation (Affordable Care Act), the FDA has now published its guidelines for restaurants to inform consumers of the calorie counts of food. It establishes requirements for nutrition labeling of standard menu items for chain restaurants and chain vending machine operators.
This is important because Americans now consume an estimated one-third of their total calories from foods prepared outside the home. Consumers are generally unaware of the number of calories they consume from these foods, and being overweight or obese increases the risk of a number of diseases including heart disease, type 2 diabetes, stroke, and cancer.
Here’s what the guidelines say:
— Restaurants with 20 or more locations must disclose the number of calories in each standard menu item on menus and menu boards (have 19 chain locations? You get a pass. Daily specials also get a pass.)
— Additional written nutrition information must be available to consumers upon request (total fat, saturated fat, cholesterol, sodium sugars, carbs, fiber, protein, etc.)
— The menu must say that the additional nutritional information is available. Read more »

If you believe everything you read on the Internet, then is seems that a chemical found in thousands of products is causing an epidemic of severe neurological and systemic diseases, like multiple sclerosis and lupus. The FDA, the companies that make the product, and the “medical industrial complex” all know about the dangers of this chemical, but are hiding the truth from the public in order to protect corporate profits and avoid the pesky paper work that would accompany the truth being revealed.
The only glimmer of hope is a dedicated band of bloggers and anonymous email chain letter authors who aren’t afraid to speak the truth. Armed with the latest anecdotal evidence, unverified speculation, and scientifically implausible claims, they have been tirelessly ranting about the evils of this chemical for years. Undeterred by the countless published studies manufactured by the food cartel that show this chemical is safe, they continue to protect the public by spreading baseless fear and hysteria.
Hopefully, you don’t believe everything you read on the Internet, and you don’t get your science news from email SPAM, where the above scenario is a common theme. While there are many manifestations of this type of urban legend, I am speaking specifically about aspartame — an artificial sweetener used since the early 1980s. The notion that aspartame is unsafe has been circulating almost since it first appeared, and like rumors and misinformation have a tendency to do, fears surrounding aspartame have taken on a life of their own.

We are a nation stricken with an epidemic of obesity, which contributes to the incidence of diabetes and heart disease. Each of these has been linked to consumption of sugar intake, and in particular, sugar-sweetened beverages.
There’s nothing evil about sugar — it’s just that too much of it in certain forms is bad for you. For the purpose of definition, sugar-sweetened beverages contain added, naturally-derived caloric sweeteners such as sucrose (table sugar), high-fructose corn syrup, or fruit juice concentrates.

I’ve been waiting for this soup for weeks. Eleven weeks, to be exact. That’s how long I was enrolled in a research diet study, and unable to eat anything other than the food they provided me, which was nowhere near as delicious as this soup.
The study is designed to compare the effects of three different diets — the American Diet, the Mediterrnean Diet, and a high-protein diet — on weight loss and cardiovascular disease risk.
I randomized to the American Diet, meaning that Thursday’s lunch was a slice of pizza with potato chips and an afternoon snack of Oreos and chocolate pudding, Saturday’s lunch was hamburger and fries, and the most veggies I ever saw at one sitting was a measly stalk of broccoli.
Despite this, I lost 30 pounds over the 11 weeks of the study, primarily because my caloric intake was only 1,200 calories per day, carefully calculated based on my basal metabolic rate. Read more »
