Duh!

Low-Cal Diets May Make You Gain Weight - MSN




..."For the first time in humans, we are finding out that cutting your calories increases cortisol," said lead researcher A. Janet Tomiyama, a Robert Wood Johnson Foundation Health & Society Scholar at the University of California, San Francisco.

..."The term 'dieting' brings to mind deprivation, starvation, being miserable and uncomfortable and ultimately failing in weight-loss efforts," said Samantha Heller, a dietitian, nutritionist and exercise physiologist who is familiar with the study.

...Burning more calories than you consume is how your body loses weight, she said. "However, severe calorie restriction, diet fads, pills and potions, detox cleanses and other quacky approaches to weight loss only contribute to people's diet failures and, in fact, may increase the likelihood of regaining even more weight than what was lost—if any," Heller added.

..."By eating foods of higher overall nutritional quality, fullness can generally be achieved on fewer calories, eliminating the need for deprivation," Katz said. "In addition, physical activity can accelerate weight loss, promote health and alleviate stress in the bargain."

That's because your body isn't interested in calories - it's interested in nutrients! It's not interested in carbs, fats, or proteins so much as what's contained in them - magnesium, potassium and all the other essential vitamins and minerals that exist. Less calories=less nutrients. Anyone surprised that would be a recipe for failure? Part of the reason processed food is so harmful is because the nutrients are stripped away - the other part being the franken-gredients that replace said nutrients.

How do you know if you are eating processed, nutrient-naked food? Well, if it has a food label on it - chances are you've been had. Think about it. I don't see any labels in the produce section. Hmmm, don't see any in the meat dept. either. Or the farmers market - or farm in my case. Kinda makes all the confusion and emphasis on understanding and policing food labels kinda silly eh? There are a few exceptions of course - store bought eggs come to mind - so another clue could be if your ingredient list is longer than say, 2 items - or contains any ingredients that would get you a triple word score in Scrabble.

While processed and refined carbohydrates have been getting their just villification as of late, care must be taken to not ignore processed fats and proteins as well. The increased consumption of vegetable/canola oils and nitrate laced meats role in our ever declining health cannot be understated.

On the other end of the spectrum are those that are somehow under the impression that nutrients operate in a vacuum. You know, all those nutjob RD's out there telling you to gulp up all that FAT-FREE dairy to get your vitamin D & K. Problem is, those are fat soluble vitamins. No fat=no absorption. Oops.

Speaking of fat-free dairy... Full-fat Dairy for Cardiovascular Health. Double Oops.

Another Headline...

Science Daily: Bacon or Bagels? Higher Fat at Breakfast May Be Healthier Than You Think

"The UAB research revealed that mice fed a meal higher in fat after waking had normal metabolic profiles. In contrast, mice that ate a more carbohydrate-rich diet in the morning and consumed a high-fat meal at the end of the day saw increased weight gain, adiposity, glucose intolerance and other markers of the metabolic syndrome.

"Studies have looked at the type and quantity of food intake, but nobody has undertaken the question of whether the timing of what you eat and when you eat it influences body weight, even though we know sleep and altered circadian rhythms influence body weight," said the study's lead author Molly Bray, Ph.D., professor of epidemiology in the UAB School of Public Health."

"Conventional wisdom has dictated that fat from red meat is a risk factor for heart disease, but ..."

...So starts an article I came across this morning - "Processed Meat May Harm the Heart" - Healthday. The sentence finishes as follows:

"...a new analysis from Harvard researchers finds it's eating processed meat -- not unprocessed red meat -- that increases the risk for heart disease and even diabetes."

Other notable passages:

..."The researchers found that people who ate unprocessed red meat did not significantly increase their chances of developing heart disease or diabetes. However, eating processed meat was linked to an increased risk for the two conditions.

In fact, for every 50-gram (1.8-ounce) serving, the risk for heart disease jumped 42 percent and the risk for diabetes increased 19 percent."

and..

"When we looked at average nutrients in unprocessed meats and processed meats eaten in the U.S., we found that they contained similar amounts of saturated fat and cholesterol," Micha said. "In contrast, processed meats contained, on average, four times higher amounts of sodium and two times higher amounts of nitrate preservatives."

This suggests that salt and other preservatives, rather than fats, probably explain the higher risk for heart attacks and diabetes seen with processed meats, Micha said.

Going well so far. Then...

...Both red and processed meat and other foods, such as butter and cheese, that are high in saturated fat have been linked to chronic disease, Heller said, adding that people should limit consumption of them as well.

"Going low- or no-fat with dairy products helps lower our intake of saturated fat," she said. "Choosing healthy protein sources -- such as white-meat poultry, low-mercury fish, soy, nuts and beans -- and focusing on moving in the direction of a more plant-based diet will help us all live longer, healthier lives."

Gotta take the good with the bad as the saying goes.
