Your metabolism burns calories for weight reduction. Higher metabolism means more calories burned and faster weight reduction. Eating well, exercising, and living a healthy lifestyle can speed up your metabolism, but aging is uncontrollable. Older folks find it tougher to lose weight since their metabolism slows.
Teenagers can eat everything they want without gaining weight, thus their metabolism is at its best. By midlife, in their 30s and 40s, it starts to drop, making weight loss harder. Despite this prevalent belief, a new study reveals that metabolism declines later in age. So it's not responsible for midlife waistline growth.
Herman Pontzer, PhD, Duke University assistant professor of evolutionary anthropology, and an international team evaluated over 6,600 people's average calorie burn. It was given to 95-year-olds in 29 nations in one week. The purpose of this study was to investigate aging bodily changes. Their findings suggest...
The study showed that newborns and toddlers burn the most calories daily. They have the fastest metabolisms. The researchers observed that newborns burn 50% more calories for their body size after their first birthday.
Overall metabolism slows by 3% throughout puberty. It stabilizes until 20, when it accelerates again. No significant increases in daily calorie consumption occurred throughout this era, surprising the researchers. Puberty and menopause were expected to increase metabolic rate, but they didn't.
The study found that middle-aged adults gain weight and lose it harder, but sluggish metabolism is not the cause. Energy expenditure was most steady throughout the 20s–50s. Even throughout pregnancy, daily calorie burn remains constant.
After 60, your metabolism slows. It decreases 1% year till 90. A 90-year-old burns 25% less calories than in midlife. Muscle loss may be at blame, say researchers.
Your metabolism does not affect weight reduction or midlife weight gain. Lifestyle and underlying condition may contribute.
