December 19, 2013We are all aware of the serious negative effects of long-term overeating and sedentary life styles, including obesity, diabetes and high blood pressure. Past research has indicated that even a few days of eating more calories than you use has negative health effects. However, researchers from the University of Bath in Great Britain have found that daily exercise may actually counteract the negative affects of short term inactivity and overeating! The week-long study included 26 healthy men, ranging in ages from their late teens to early thirties. All participants gave blood samples and had oral glucose tests; samples of abdominal fat was also taken from all members of both groups. Volunteers were separted into two groups, one group was asked to limit physical activity to below 4,000 steps each day and eat fifty per cent more calories than normal. The other group was told to eat seventy-five percent more calories and run on a treadmill for 45 minutes per day. This was done so the 'net daily surplus' of calories was the same for both groups. The results were amazing! The inactive group demonstrated a marked decline in blood sugar control, fat cells indicated that both nutritional balance and metabolism were disturbed. Meanwhile the results for those in the exercise group were markedly different: blood sugar levels remained stable, and changes in fat cells were significantly lower! In other words, even though the exercise group ate more, and both groups had the same 'net' daily energy intake/output ... the participants in the exercise group were protected from many of the negative effects of overeating! This is an important new information that supports the importance of exercise in our daily lives! Remember, when you're not in a period of overeating and lowered activity, the benefits of exercise will keep you healthy and happy throughout the year!
