Obesity Decreases Heart Rate Reactions Leading To…More Weight Gain

THE BLOGMEISTER GIVETH UPLIFTING POSTS…AND HE REPLACETH THEM RIGHT AWAY…OBESITY IS ASSOCIATED WITH SEDENTARY HABITS WHICH WOULD THEN CREATE A VISCIOUS CIRCLE OF LOW HEART RATE RESPONSE TO STIMULI AND THUS LOWER OVERALL METABOLISM….DIET + EXERCISE IS SUPPORTED YET AGAIN…READ EXCERPTS BELOW:

“Contrary to their expectations, British researchers have found that when exposed to psychological stress, obese people show smaller changes in their heart rate compared with normal-weight individuals.

Dr Douglas Carroll at the University of Birmingham, and colleagues there and at the University of Glasgow, examined the association between obesity and the magnitude of heart reactions to stress in 1 647 adults living in the community.

Blood pressure and heart rate were measured at rest and in response to psychological stress – performing mental math problems under a time deadline. Measurements were taken when the study began and five years later.

Contrary to expectations, heavier individuals and “those categorised as obese displayed smaller heart rate reactions to stress,” Carroll and colleagues report in the journal Psychosomatic Medicine.

Less nervous system activity ups food intake?
Moreover, “high heart rate reactivity was associated with a reduced likelihood of becoming obese in the subsequent five years,” they write.

Low nervous system activity, which leads to smaller heart rate changes, may be associated with weight gain and the findings of this study “are certainly in line with that notion,” the investigators say.

Carroll’s team notes that other researchers have suggested that reduced nervous system activity may increase food intake.

Be that as it may, they conclude that low heart rate reactivity may be a risk factor for developing obesity. “– (Reuters Health, September 2008)
