Yahoo has a brief article with a few more details. For $30 you can read the original scientific report from Journal of the American Medical Association.

Obesity in this context is defined as a body mass index of 30 or higher. Calculate your BMI here.

Is it your fault if you’re obese?

Do Potatoes Make You Fat or Diabetic?

Researchers in Denmark say “no.” French fries, maybe.

“The identified studies do not provide convincing evidence to suggest an association between intake of potatoes and risks of obesity, T2D, or CVD. French fries may be associated with increased risks of obesity and T2D although confounding may be present. In this systematic review, only observational studies were identified. These findings underline the need for long-term randomized controlled trials.”

Obesity Paradox Resolved?

Not familiar with the obesity paradox? Read about it at Wikipedia, which may or may not be accurate.

From a recent article at MPT:

“A massive meta-analysis pooling data from millions of people in several countries reaffirmed that body mass index (BMI) has a J-shaped relationship with mortality, with the lowest death rates among those in the traditional “normal” range of 20-25.

The study of nearly four million people revealed that those in every BMI category above and below the normal range had significantly higher mortality rates.The elevation in risk applied to even mildly overweight people, and was highest for those with overt obesity, according to researchers with the Global BMI Mortality Collaboration, a part of the University of Cambridge.”

“Our results challenge recent suggestions that overweight and moderate obesity are not associated with higher mortality, bypassing speculation about hypothetical protective metabolic effects of increased body fat in apparently healthy individuals,” wrote the authors. Their data showed the J-shaped relationship maintained for every age group, albeit attenuated somewhat among those in the 70-89 age range.”

Dr. Eades Attempts to Explain the U.S. Obesity Epidemic

Dr. Michael Eades of Protein Power fame thinks he knows why we’ve gotten fat starting 35 years ago:

Along with carbohydrates, vegetable oils have increased dramatically in the typical American diet. Over the same time period, we’ve all started eating away from home more and more, so that we’ve lost control of exactly what kinds of fats we’ve been eating.

Click the link for the details of his hypothesis, which involves the effects of various dietary fats and carbohydrates on intracellular energy metabolism and insulin resistance.

Natural Versus Drug Therapy for Metabolic Syndrome

"These are flying off the shelves!"

“But selling drugs is good for the economy!”

Have you heard that 60% of adults in the U.S. are taking prescription drugs? That’s up from 50% a decade ago. UPI has the pertinent details. A snippet:

Many of the most used drugs reflect the effects of metabolic syndrome, a group of conditions tied to obesity and diet.

“Eight of the 10 most commonly used drugs in 2011–2012 are used to treat components of the cardiometabolic syndrome, including hypertension, diabetes, and dyslipidemia,” researchers wrote in the study, published in the Journal of the American Medical Association. “Another is a proton-pump inhibitor used for gastroesophageal reflux, a condition more prevalent among individuals who are overweight or obese. Thus, the increase in use of some agents may reflect the growing need for treatment of complications associated with the increase in overweight and obesity.”

I’m not anti-drug, generally. Lord knows I prescribe my fair share. But in addition to the cost of drugs, we have side effects and drug interactions to worry about. If we in the U.S. would effectively attack overweight and obesity, we’d be much better off.

But it’s a lot easier to just pop a pill, isn’t it?

Especially if someone else is paying for the pill.

Obesity Soon to Affect Average Life Span in U.S.

“The medical community seems to be under a fog that we can constantly and forever reduce death rates, and that’s simply not true,” said Professor Olshansky, who published a study in 2012 showing that life spans for white women without a high school diploma had declined, a rare event in developed countries.

“You need to look at the health status of the living,” not the mortality statistics of the dead, he said, adding that obesity is afflicting younger generations in a way that will eventually make the numbers worse.

Bariatric Surgery Linked To Increased Suicide Attempts

according to an article at MedPageToday.

Band Gastric Bypass Surgery

Self-harm emergencies rose by 50% after gastric bypass surgery in the Canadians in this study.

Folks on my diets lose weight without an increase in suicide risk, as far as I know. Click on my name for the diets.

For God’s sake, if you do nothing else, call the National Suicide Prevention Lifeline if you’re thinking about killing yourself. What have you got to lose? Suicide really is a permanent “solution” for a temporary problem.

Is Food Insecurity Really a Problem in the U.S.?

I’m hearing ads on the radio that many in the U.S., including children, are suffering from hunger. Nutrition science journals in the last few years are covering “food insecurity,” which many would assume means not having enough food or fearing the lack of food.

These concerns seem at odds with the fact that two-thirds of us are overweight or obese. So how many of us at normal or below-average weights suffer from food insecurity or hunger?

James Bovard breaks it down for you in an excellent article. Read the whole thing. Some morsels (heh):

  • seven times as many (low income) children are obese as are underweight
  • 40% of food stamp (SNAP) users are obese, compared to 30% in the overall U.S. adult population
  • if the food stamp program would prohibit purchase of sugary drinks, it would prevent 141,000 children from becoming fat and save a quarter million adults from type 2 diabetes

Fat hungry people would be less hungry if they’d cut way back on refined, nutrient-poor carbohydrates, replacing with protein and healthy fats.

Getting Bariatric Surgery to Improve Your Type 2 Diabetes? RYGB May Beat LAGB

An article at Diabetes Care suggests that insulin-treated T2 diabetics getting bariatric surgery were almost twice as likely to get off insulin if they had roux-en-Y gastric bypass rather than laparoscopic adjustable gastric banding. The former procedure is also generally more effective for weight loss.

If you think bariatric surgery is a sure-fire cure for type 2 diabetes, it’s not. I would go as far as I could with diet and exercise before going under the knife.

Paleolithic Diet May Help Reduce Risk of Obesity

…according to a basic science study published in the British Journal of Nutrition. The mechanism for reducing obesity risk would be increased satiety. We’ve seen that before with the paleo diet as compared to a Mediterranean-style diet. Disappointingly, the researchers didn’t see any paleo diet benefits in these healthy study participants in terms of glucose and insulin metabolism.

I haven’t read the report, don’t have it, don’t know when I’ll read it.

Abstract

There is evidence for health benefits from ‘Palaeolithic’ diets; however, there are a few data on the acute effects of rationally designed Palaeolithic-type meals. In the present study, we used Palaeolithic diet principles to construct meals comprising readily available ingredients: fish and a variety of plants, selected to be rich in fibre and phyto-nutrients. We investigated the acute effects of two Palaeolithic-type meals (PAL 1 and PAL 2) and a reference meal based on WHO guidelines (REF), on blood glucose control, gut hormone responses and appetite regulation. Using a randomised cross-over trial design, healthy subjects were given three meals on separate occasions. PAL2 and REF were matched for energy, protein, fat and carbohydrates; PAL1 contained more protein and energy. Plasma glucose, insulin, glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic peptide (GIP) and peptide YY (PYY) concentrations were measured over a period of 180 min. Satiation was assessed using electronic visual analogue scale (EVAS) scores. GLP-1 and PYY concentrations were significantly increased across 180 min for both PAL1 (P= 0·001 and P< 0·001) and PAL2 (P= 0·011 and P= 0·003) compared with the REF. Concomitant EVAS scores showed increased satiety. By contrast, GIP concentration was significantly suppressed. Positive incremental AUC over 120 min for glucose and insulin did not differ between the meals. Consumption of meals based on Palaeolithic diet principles resulted in significant increases in incretin and anorectic gut hormones and increased perceived satiety. Surprisingly, this was independent of the energy or protein content of the meal and therefore suggests potential benefits for reduced risk of obesity.
