      Calorie restriction or carb depletion to increase lifespan

      May 1, 2010 /

      Since the discovery that calorie restriction increased lifespan, many studies have been performed including studies with non-human primates; all with overwhelming evidence. However, the mechanism by which lifespan increases through calorie restriction, has eluded researchers.

      Data on the physiologic effects of caloric restriction in rhesus monkeys resembles rodent studies demonstrating reduced body and fat mass, lower blood glucose, insulin, leptin, free T3 (decreased body temperature), and serum triglycerides. Interestingly, centenarians have lower blood glucose, insulin, leptin, free T3 and serum triglycerides than those who do not live to be over one hundred years old. One can conclude, the fundamental mechanism by which calorie restriction improves lifespan appears to alter these metabolic factors.

      A new study analyzed the data from patients attending a private practice. These patients were referred for the treatment of diabetes, cardiovascular disease, overweight, fatigue, and other chronic diseases of aging.

      The diet:
      ? Calories were not explicitly restricted; patients were told to eat when they were hungry.
      ? Recommended sources of fat included; raw nuts, seeds, avocados, olives, olive oil, flax oil, and cod liver oil.
      ? Protein intake was limited to 1.0g/kg of lean body mass. If the subjects exercised it was increased to 1.25g/kg.
      ? Recommended sources of protein included sardines, fish, eggs, tofu, chicken, turkey, wild meats, low fat cheeses, seafood, and vege burgers.
      ? Carbohydrate sources included only non-starchy fibrous veges; lettuce, greens, broccoli, cauliflower, cucumbers, mushrooms, onions, peppers, etc.
      The average daily macronutrient intake ended up being 20% carbs (most of which was fiber), 20% protein, and 60% fats.

      The results: Serum insulin decreased by 48 percent, leptin decreased by 8 percent, fasting glucose by 40 percent, triglyceride by nearly 8 percent, and free T3 by almost 6 percent.

      The key factor in this study is the participants were not limited in the amount of food they could consume. The researchers wanted to focus on the types of foods or macronutrients that would result in improved health and a longer life.

      Cholesterol no longer a risk factor for heart disease. Look to CRP?

      April 29, 2010 /

      Dr. James Stein, MD from the University of Wisconsin Medical School in Madison, praised the JUPITER study for exposing the fact that current therapeutic LDL-cholesterol levels are not only arbitrary, but are in fact a poor indicator of cardiovascular disease (CVD) risk. ?Most patients with heart attacks have normal cholesterol values,? he stated. With the cholesterol theory crumbling the industry is under intense pressure to come up with a new risk factor, and one that can be treated with the same statin drugs they have invested so much money in. Enter Dr. Ridker and C-reactive protein (CRP). Ridker has been pushing treating CRP with statins for years. But is CRP a risk factor? A National Panel on CRP found no evidence treating CRP levels will improve survival rates (www.urmc.rochester.edu/pr/News/story.cfm?id=182). Elevated CRP levels are associated with many things including; anger, stress, arthritis, cancer, lupus, pneumonia, TB, oral contraceptive use, pregnancy, heart attacks, surgery, trauma, intense exercise, etc. It?s a marker for disease, not the cause. But since statins lower CRP levels slightly, you can count on CRP becoming the new cholesterol. The public will be made to fear CRP, be tested for it, and be put on dangerous statins to lower it. What a racket.

      Golf: Improve your game and prevent injuries

      April 17, 2010 /

      In an article I wrote 10 years ago, I addressed the importance of strength training for golfers. In this article, “Golf: Reducing your risk of injury and improving your game.” I wanted to focus on preventing injuries and targeting the specific muscles used while playing golf.

      The mechanics of a golf swing can cause a variety of injuries or aggravate previous injuries. The most common area golfers experience injuries is the lower back. Other areas golfers complain about are the shoulder, or more specifically the rotator cuff, the left elbow, and the left wrist (for right handers). Unfortunately, there is little data available about the seriousness of injuries as a result of playing golf or how to reduce them. However, if we apply what we know from other sports through research and empirical data, I have seen many golfers not only decrease their risk of injury but improve their game.

      A golfers edge, strength training

      April 15, 2010 /

      You would think as fanatical as golfers are, seemingly willing to do just about anything to improve their game, they would be more than interested in strength training. The fact is however, the vast majority of golfers are still not taking advantage of this inexpensive tool that would not only improve their game, but improve their health.

      Golfing is not an inexpensive sport. And golfers spend hundreds to thousands of dollars on equipment alone in an effort to gain an edge on the course. The fact of the matter is, given the choice between expensive equipment and hard work coupled with strength training, I’ll take hard work coupled with strength training every time.

      I you’re going to spend the money on equipment and lessons, why not make sure your physically at your best so you not only can truly take advantage of your expense, but help ensure a long career. The following is an article, “Strength training: Is it the newest edge for golf“I wrote over a decade ago and is as pertinent today.

      If a women wants to attract a man, ditch the Chanel No. 5

      April 14, 2010 /

      In a large percentage of animals, females are only fertile during a brief period of time surrounding ovulation. For the males of these species, this period promotes mating behavior. There is evidence that shows that males can actually smell when a female is ovulating. Recent studies indicate that the olfactory sense may play a large role in human attraction and mating also.

      The researchers performed two separate but related experiments. In the first scenario, the scientists gave four women plain, white T-shirts. The women wore the shirts when they slept over three days during ovulation or late follicular phase. Five days later, the women again wore T-shirts for three days when they slept during the luteal phase, which is far from ovulation. At the end of every night sleep the shirts were collected and put in bags separately then frozen.

      In the second experiment, the scientists added an extra variable: fresh T-shirts that hadn’t been worn by anyone, which were also placed in bags.

      The researchers asked dozens of men to stick their noses into the bags. As the men sniffed the shirts, scientists sampled the participants’ saliva, which was used to measure testosterone. Men who smelled the shirts of ovulating women in the first experiment had, on average, testosterone levels that were 37 percent higher than the men who smelled the shirts of non-ovulating women. For the second experiment, the testosterone levels of the men who smelled the T-shirts of ovulating women were, on average, 15 percent higher than men who sniffed the two other T-shirt samples.
