Sat, 30 December 2006 Exercise, the Mediterranean Diet, Weight Loss, and your Health This week I tried experimenting with the compressor feature on my microprocessor and it didn't workout exactly right. The podcast has an odd background sound when listened to with headphones. Oddly enough, this background sound is unnoticeable when the podcast is listened to over external speakers. The technical aspects of podcasting continue to trip us up - sorry. The show this week takes a look at two studies using lifestyle interventions to prevent heart disease. One study focuses on exercise and the other one on the Mediterranean diet. You will be surprised, and excited, to hear how lifestyle interventions to prevent heart disease stack up against medical interventions. The lessons learned in this podcast can be applied directly to your plans for a healthy weight loss program.

Sat, 23 December 2006 Is it Okay to be Overweight if You are Fit? In this episode of Fitness Rocks we review four studies from the medical literature that examine the relationship between fitness and obesity and the risk of developing heart disease, or dying prematurely from any cause. Do high levels of cardiorespiratory fitness compensate for the known negative health consequences of being overweight or obese? Put another way - is it okay to be obese if you are fit? Medical studies provide different perspectives - much of the difference results from the different ways the various studies were designed. What are the Fitness Rocks' conclusions? Listen to podcast 026 for all the details. This week Fitness Rocks welcomes a new co-host to the show - Dr Jenny. Dr Jenny is board certified in Internal Medicine and board certified in Cardiology. She's a serious expert!

Sat, 16 December 2006 Glycemic Index and Weight Loss - What You Should Know In this episode I try to explain the glycemic index and its implications for health and weight loss. I intentionally ignored the glycemic load, not because it isn't important, but because the discussion was already complicated enough. Glycemic index is a measure of how much, and how fast, a particular carbohydrate containing food raises blood sugar. This rise in blood sugar precipitates a corresponding rise of insulin that that is required for the cells of our body to utilize this absorbed sugar from the food we eat. It turns out that the glycemic index reveals some very interesting aspects about the relationship between the foods we eat and our health as well as our weight. But the glycemic index is not as clear-cut as one would hope, and it is the subject of ongoing debate and controversy within the medical and scientific community. Listen to the program and send me your e-mail questions and comments. It is a complicated topic.

Sat, 2 December 2006 Lifestyle Habits and Your Blood Pressure Twenty-five percent of the adult population in the United States has high blood pressure, and forty-seven percent of these people do not have their blood pressure adequately controlled. The risk of developing high blood pressure increases with age. High blood pressure is a major risk factor for stroke, heart attack, congestive heart failure, blindness, and kidney failure. In this episode of Fitness Rocks we talk with exercise physiologist Paul Sorace about how you can reduce your blood pressure with diet and exercise. We discuss what the medical research has shown regarding the best type of diet to keep blood pressure under control. Paul also shares his insights into the best ways to exercise. Fitness Rocks will be having its first teleseminar sometime in December. The teleseminar is free and will be a discussion on how to make an effective New Year's weight-loss resolution - and how to keep it. The teleseminar will include a dietitian, an exercise physiologist, and two psychologists discussing effective weight-loss strategies and answering your questions. If you want to participate in the teleseminar send us an e-mail through the contact button and we will send you the date/time and telephone number for the conference - it's free!
