Weight Loss Dieting VS Exercise
People in between 50s and 60s who want to lose weight might deem heading to the cardio workout room instead of counting calories, suggests new investigate out this month.
Both those who dieted and those who exercised lost a significant amount of weight, as per findings from an NIH-funded study on whether a calorie-restriction diet can extend lifespan. On the other hand, while exercisers maintained their strength and muscle mass and improved aerobic capacity, those who dieted lost muscle mass, strength and aerobic capacity.
Edward Weiss, Ph.D., said "Exercise-induced weight loss provides the additional benefit of improving physical performance capacity,", lead author and assistant professor of nutrition and dietetics at Saint Louis University's Doisy College of Health Sciences.
"If push comes to shove and somebody wants to know if they should diet or exercise to lose weight, I would suggest exercise, provided they are willing to put in the extra time and effort and not offset the gains they make by eating more".
Of the 34 study participants, 18 dieted and 16 exercised to lose weight.
The ambition of dieters was to reduce their calorie utilization by 16 percent the first three months, and by 20 percent the next nine. similarly, exercisers strove to burn 16 percent more calories the first three months, increasing to 20 percent the next nine months.
Both of groups lost between 9 and 10 percent of their total body weight. Those who exercised occupied in 60 minutes of cardiovascular activity six times a week, such as a brisk three- to four-mile walk. Those exercisers who worked out for 90 minutes a day, loose of more pounds - 15 to 20 percent of their body weight.
Those who dieted lost muscle mass while those who exercised did not. This is because exercisers routinely challenged their muscles, which prevented muscle tissue from degrading. Dieters didn't work their muscles as vigorously as those who exercised.
Weiss says "In addition, once a person loses weight, his or her muscles don't have to work as hard at everyday movements, such as rising from a chair, walking up steps or getting out of a car,".
"Because they're carrying a lighter load, less demand is placed on them".
The muscles dieters use to carry their bodies "detrain," in much the same way that a weight lifter using less weight in the gym doesn't develop as large of muscles as one who uses heavier weights.
Weiss was cautious not to rule out the reimbursement of dieting, though.
