Consuming excess calories increases body fat, regardless of how many calories come from protein. High-protein diets do affect energy expenditure and storage of lean body mass, just not body fat storage.
To evaluate the effects of overconsumption of low-, normal-, and high-protein diets on weight gain, researchers conducted a single-blind, randomized controlled trial of 25 healthy, weight-stable adults in an inpatient metabolic unit in Baton Rouge, La. Patients were ages 18 to 35 with a body mass index between 19 and 30. The study was headed by George A. Bray, MD, MACP.
After consuming a weight-stabilizing diet for 13 to 25 days, participants were randomized to diets containing 5% of energy from protein (low protein), 15% (normal protein) or 25% (high protein). Only the kitchen staff who supervised participants while they were eating knew the assignments. There was no prescribed exercise, and alcohol and caffeine were restricted.

I came across this article the other day regarding use of the daVinci robot to perform base of tongue surgery for obstructive sleep apnea.
For those who don’t know, the daVinci robot system made by Intuitive Surgical is a robotic system whereby the surgeon directs the arms of the robot to perform surgery in difficult-to-access areas of the body.
My feeling is that using a robot to perform sleep apnea surgery is way overkill akin to using a $50,000 sniper rifle to kill an ant on the wall.
Everything the daVinci robot can do can also be done without the robot with equivalent patient outcomes. In fact, Read more »

It is risky.
Stay fresh. Avoid repeating yourself. Don’t rant. Never preach. These would be the ‘rules’ of supposedly good blogs.
And, of course, doctors that dare to take a stance on health issues risk being perceived as pretentious. I get this.
So it is with trepidation that I write a follow-up to last week’s CW post about right ventricular damage immediately after an extreme race effort. Notwithstanding the pompousness concern, I also wish to avoid being labeled anti-exercise. Few believe more strongly in the healing powers of exercise.
But last Wednesday’s comments (both on the blog, Facebook and here on Dr. Val Jones’ BetterHealth blog) were just too good to let rest.
On the assessment of studies: Read more »

Vitamins, herbs and other dietary supplements are sold as natural alternatives to pharmaceuticals and many people turn to them in an attempt to improve their health. Others seek supplements to lose weight or after hearing that they can help with serious medical conditions. These products are now used at least monthly by more than half of all Americans—and their production, marketing and sales have become a $23.7 billion industry, according to the Nutrition Business Journal.
What Are Dietary Supplements and How Are They Regulated?
98-year-old Bob Stewart, a retired podiatrist and senior Olympian, credits his use of supplements for his healthy aging. Writer Betsy McMillan, a mother of two now adult children, however, nearly suffered permanent liver damage due to a supplement that contained potentially fatal levels of niacin.
Unlike pharmaceuticals—which must be FDA-approved as safe and effective before they can be marketed—supplements are considered as foods by regulators and assumed to be safe until proven otherwise. Although pharmaceutical manufacturers face inspections to ensure that the right dose is in the right pill without dangerous contaminants, supplements do not undergo such intense government scrutiny.
Despite many reports of health problems, Read more »

When you sit quietly, your heart slips into the slower, steady pace known as your resting heart rate. A new study suggests that an increase in this rate over time may be a signal of heart trouble ahead.
Your heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.
Many factors influence resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow it down. (In his prime, champion cyclist Lance Armstrong had a resting heart rate of just 32 beats per minute.) Stress, medications, and medical conditions also influence the heart rate.
In today’s Journal of the American Medical Association, researchers from Norway report Read more »
