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.
Patients were 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 »

This article (full reference below) on the additional benefits an individual gains from having a reduction mammoplasty (RM) has been published online ahead of print. The authors performed a systemic review of the literature focusing on functional outcomes after RM with regard to physical and psychological symptom improvement.
The authors performed a systematic review of the English literature using PUBMED for the period between 1977 to 2010. Studies were chosen that addressed the physical and psychological benefits of RM using a validated questionnaire.
The authors note that nearly eighty thousand breast reductions were performed in 2009. For insurance coverage in the United States a woman seeking breast reduction must have complaints of physical symptoms (i.e., Read more »

Fear of the “freshman 15″ weight gain is overrated, says one researcher who found that the average college student packs on only between about 2.5 and 3.5 pounds.
And it might not even be the college lifestyle that causes one’s backpack to become a little more snug. Rather, it’s part of the natural transition into adulthood. The typical freshman only gains about a half-pound more than a same-age person who didn’t go to college.
“Not only is there not a ‘freshman 15,’ there doesn’t appear to be even a ‘college 15′ for most students,” researchers said in a press release.
The researchers concluded that the myth of the freshman 15 may contribute to Read more »

Tummy Tuck surgery is almost invariably greatly appreciated by the proper patient. These top ten facts might help you figure if you are such a person. 
(1) Tummy Tuck surgery is one of the largest scale operations a plastic surgeon can offer a patient.
(2) Patients who have lost a good deal of weight or completed child bearing involving large weight gain and loss are the most common candidates. Patients do not lose much weight from the operation itself in most cases….maybe a few pounds on average.
(3) Post-operative pain used to make it necessary to admit the patient to a hospital for narcotics.
(4) Pain pumps when properly utilized can Read more »
