New Fat Burner Found in Remote West African Village

Suppose you could drop all of your unwanted fat... without going to the gym or forcing yourself to eat rice cakes and tofu burgers? I have a new clinical study on my desk that says it’s possible.

It may be the most successful weight loss compound ever tested.

The people in this study -- which was published in the medical journal Lipids in Health and Disease -- lost an average of 28 pounds and 6 inches off their belly. And they didn’t change their diet or exercise habits.

Keep reading to find out how they did it ... ...




How Full Fat Helps Diabetes

After all these years reading and writing about health, I can’t help but notice that certain basic nutritional truths keep reasserting themselves. For instance, it seems blatantly obvious to me that we could save lots of money researching the root causes of chronic illness by saying simply this -- always eat in moderation, and choose foods that are as close to their natural states as possible.

As the latest example, let me tell you about some research I have just reviewed that says people who consume whole-fat dairy products -- as opposed to their processed, lower-fat versions -- have a 60% lower incidence of diabetes! This flies in the face of what experts have been advising for decades -- that everyone but babies and toddlers should choose milk, cheese, yogurt and other dairy products with the lowest possible fat content, because the saturated fat that’s prominent in dairy products is bad for your health.

Fat Is Beautiful?

Now, in a study from Harvard published in Annals of Internal Medicine, a team of researchers has found that people with the highest circulating levels of a type of fatty acid that is found only in whole-fat dairy are one-third as likely to get diabetes as those with the lowest circulating levels. Higher levels of the fatty acid -- called trans-palmitoleic acid -- were also associated with lower body mass index (BMI)... smaller waist circumference... lower triglycerides (potentially harmful blood fats)... higher levels of HDL "good" cholesterol... less insulin resistance... and lower levels of C-reactive protein, a marker for general inflammation.

How the study was done: At the study’s start, researchers began with baseline measurements of glucose, insulin, inflammatory markers, circulating fatty acids and blood lipids (such as triglycerides and cholesterol) from stored 1992 blood samples of 3,736 participants in the National Heart, Lung, and Blood Institute-funded Cardiovascular Health Study. Those data were compared with the same participants’ dietary records and recorded health outcomes (including the incidence of diabetes) over the following 10 years. During this period, 304 new cases of diabetes were recorded. When the participants were grouped according to their circulating levels of trans-palmitoleic acid, the researchers discovered that those with higher levels had the lowest rates of diabetes.

how much dairy?

I spoke with the study’s lead researcher, Dariush Mozaffarian, MD, DrPH, associate professor of epidemiology at Harvard School of Public Health, who told me that other studies have suggested a similar phenomenon with dairy consumption, but that his is the first to have used objective chemical markers in the blood to determine the relationship between this specific fatty acid and the onset of diabetes. The participants with the highest levels averaged about two servings of whole-fat dairy foods a day.

This is not a license to indulge yourself in a daily serving of strawberry shortcake with extra whipped cream or a giant ice cream from Cold Stone Creamery... but you might want to consider switching from skim milk to whole milk with your morning cereal and selecting full-fat yogurt over low-fat or nonfat. The difference in calories isn’t great -- and you may be getting some real metabolic and cardiovascular benefits.

False Claims in Moisturizer Ads

What a smart business move it was for cosmetic and skin-care companies to formulate facial moisturizers that also contain broad-spectrum sunscreen (meaning that they provide UV-A and UV-B protection) to save our vulnerable faces from the sun’s damaging UV rays -- the ones that not only cause premature aging of the skin, leaving you with brown spots, lines and wrinkles, but also melanoma, the deadly skin cancer.

Trusting that these products actually will protect you turns out not to be such a smart move, however! A new study tested 29 facial moisturizers that promised to offer broad-spectrum UV protection, ranging in sun protection factor (SPF) from 15 to 50, and found that only a few of these products really did the trick. Shame on the marketers! I talked to Steven Q. Wang, MD, a dermatologist with Memorial Sloan Kettering Cancer Center and one of the study’s authors, about how this could be so, and he explained the problem: Most of the moisturizers protect you from UV-B waves -- in fact, the SPF number on the label refers only to UV-B -- but they don’t protect you from UV-A waves.

UV-A Rays -- Dangerous and Inescapable

This distinction is important because UV-A rays are the ones that penetrate deep into your skin and can damage cells that grow well below the surface. Additionally, those rays are ever present -- whether it’s winter or summer, raining or cloudy, because UV-A rays can pass through clouds and even get into your home. "In day-to-day living, exposure to UV-B is relatively small," Dr. Wang told me. "But UV-A rays get through glass -- so if you’re sitting in your car or your office or near a window at home, you need more UV-A protection."

The US Food and Drug Administration does not regulate the claims of such products, and there is no other regulation of UV-A claims in particular, nor any official definition of "broad-spectrum" -- so there is no government watchdog looking at what a consumer gets, which is what led Dr. Wang and his colleagues to undertake this study, published in the January 20, 2011, issue of The Archives of Dermatology.

Dr. Wang won’t reveal the brands he studied or those that passed the test, pointing out that manufacturers often change ingredients. Instead, he suggests that as consumers, we all need to look out for ourselves by examining the ingredients of any facial moisturizer with sunscreen we are considering using. And paying more doesn’t necessarily buy more protection, Dr. Wang said -- for example, the most expensive product he looked at, at $64 per ounce, offered absolutely no protection from UV-A rays.

What To Buy

So what should you look for? Examine the list of "active ingredients" on the package, and buy products that have the following:
  • A combination of avobenzone and octocrylene. Dr. Wang explained that the octocrylene makes the avobenzone more stable.
  • If avobenzone is not present, ecamsule is shown to be protective against UV-A rays. In this case, it is stable on its own.
  • Zinc oxide also offers good protection against UV-A rays.
If ever there were a case of caveat emptor, this is it. If you plan to buy a facial moisturizer with sunscreen, make sure you allot yourself a bit of extra time so you can read those labels carefully!

Digging in the Dirt

While spring officially started well over a month ago, I feel like it started today. It was my first day of digging in the dirt. I've been eyeing my garden for weeks, aching to get out there to prepare the beds for planting. After much anticipation... today was the day.
