Decreased brown fat markedly increass the risk to diet-induced obesity, diabetes, and elevated fats in the blood.

Brown fat tissue is present in newborn babies. People with a lot of brown fat have a "furnace" metabolism. They burn body fuels rapidly, and the more they consume, the more they burn, all the while maintaining a stable weight. A furnace metabolism thrives on carbohydrates. The more fuel they throw into the system, the more they burn, just like coals on a fire.

There are ways to change the percentage of brown fat in the body. Although most people normally do not advocate caffeine as a healthful food, research suggests that caffeine stimulates brown fat by increasing the metabolic rate. Caffeine, however, does other things that are not as positive. It can cause heart palpitations (especially in high amounts), and steals some of the vitamins in the body, such as C and B. Increasing multi-vitamins is helpful with any caffeine supplement.

Another way to increase brown fat is to exercise - specifically, to engage in aerobic exercise that uses oxygen. To be effective this exercise must raise the pulse rate from a resting level of about 70 up to 120 or so. A half-hour of vigorous walking four times a week can be very rewarding from a metabolic standpoint.

One last tip: too much sodium in the diet can deactivate the brown fat and promote water retention with consequent weight gain. So slow and steady exercises, pass on the salt, and make mine a Grande sugar-free vanilla latte. Thank you!

The FDA has approved a new over-the-counter weight loss drug called alli (orlistat) that is designed to absorb 25% of the fat from your meal. However, nutrition and fitness expert Dr. Len Lopez, author of "To Burn or Not to Burn, Fat is the Question" shares his reasons why the new approved weight loss drug may not be beneficial to your health.

New research is showing that medications don't make us healthier. Research is showing that losing weight with medications doesn't decrease the rate of heart attacks, strokes or diabetes. Add that to the fact that your body loses nutrients with these medications and you can easily see how these new weight loss drugs can hamper your health. Dr. Lopez discusses practical steps to losing weight which includes diet and exercise, but also covers how stress and adrenal fatigue can disrupt our hormones, such as cortisol and adrenaline. These hormonal imbalances can throw off our metabolism and take us out of our fat burning mode.

Both of Dr.Lopez's books cover a good deal of information to understand how we can correct our imbalances in piecing together the weight loss puzzle. His knowledge explores the roles of insulin and cortisol in weight gain, cravings, fatigue and more. He also explains how stress can take you out of your fat burning zone and helps you regain your blood sugar balance, as well as implementing the "Five and Two" dieting plan.

Say NO to the weight loss drugs and say YES to the empowering knowledge Dr. Lopez has to share.

The journal Diabetes Care reports obese adults who lost a substantial amount of weight through lifestyle modification and dieting regained less weight when they took the diet drug Xenical, This approach was also associated with a reduced occurrence of type 2 diabetes.

Xenical burns fat while you are eating by inhibiting the absorption of dietary fat from your food. Studies have shown that the drug promotes more weight loss than lifestyle modification alone. The study examined the effectst of Xenical in preventing weight regain in 383 obese adults who had lost an average of 31.7 pounds (14.4 kg) on an 8-week protein-rich, very-low-energy diet. The 309 participants who lost 5% or more of their bodyweight then received lifestyle counseling for 3 years while taking either Xenical or a placebo pill daily. Both groups regained some weight. Xenical patients regained an average of 10 pounds, while placebo patients put back an average of 15 pounds.

Most importantly, during the 3-year study period only 8 of 153 in the Xenical group developed type 2 diabetes compared with 17 of 156 in the placebo group. That's remarkable. Twice as many people were diagnosed with type 2 diabetes, in addition to regaining one and a half times the weight. As an aside (and not to be a whistleblower) but one of the warnings on the label says the drug should not be taken for more than 2 years. Just an FYI.

Diabetes Care reports consuming red meat and other foods high in "heme" iron, such as chicken liver, clams and oysters, appears to increase the risk of heart disease in diabetics.

Researchers followed 6,161 women with type 2 diabetes. During follow-up visits, from 1980 through 2000, the team documented 550 new cases of heart disease. After accounting for age and body weight, high intake of both heme iron and red meat appeared to increase the risk of heart disease. Specifically, women who consumed the highest amount of heme iron were 50% more likely to develop heart disease than those with the lowest intake. The risks were greatest in women who were postmenopausal.

The researchers point out that because of the study's design, the findings can't prove that high heme iron intake "causes" heart disease, only that it is "associated" with the disease. The results of this study support the suggestion that cutting back on consumption of heme iron-rich foods might be prudent for diabetics. Those of you in the market for a heart healthy diet - consider curtailing the chicken livers and aphrodisiacs of the sea.
