People of normal weight may be able to extend their life span by restricting calories, according to a new study that attempted to measure the pace of aging in people asked to cut their calorie intake by 25% over two years.
Eating fewer calories appears to slow the pace of aging and increase longevity in healthy adults, according to a study published Thursday in the journal Nature Aging.
Yes, you can do intermittent fasting for longevity every day. Research suggests that daily intermittent-fasting practices and longer-duration periodic fasting are safe strategies to improve your healthspan and lifespan.
Cutting calories by 25% slowed down the pace of aging in young and middle-aged adults by a few percentage points, compared to people who continued eating normally, the new research reveals. This first-of-its-kind study in humans adds to evidence from animal studies that the rate of aging can be changed.
Poor Food Choices
Consuming too much junk food and fast food can lead to lifestyle diseases like obesity and cancer which can reduce your lifespan by more than ten years. Instead of consuming fast food, eat a healthy diet packed with lots of fruits and vegetables, to live a long and healthy life.
No matter what your age, you can improve your fitness.
If it's been a long time since you've exercised and you're feeling less than fit, you might think that it's too late to make a change. But you're wrong. You can improve your fitness at any age.
Changes in total body weight vary for men and women. Men often gain weight until about age 55, and then begin to lose weight later in life. This may be related to a drop in the male sex hormone testosterone. Women usually gain weight until age 65, and then begin to lose weight.
Our study found evidence that calorie restriction slowed the pace of aging in humans” Ryan said. “But calorie restriction is probably not for everyone. Our findings are important because they provide evidence from a randomized trial that slowing human aging may be possible.
Exercise is one of the best ways to delay aging. And with good reason: too much time sitting (sedentary behavior) is associated with an increased risk of heart disease, diabetes, cancer, and an early death. Aerobic activity is any activity that causes you to breathe harder than normal and your heart to beat faster.
Eating Only One Meal a Day May Slow Aging
You might live longer and feel younger. One study found that fasting for 24 hours boosted anti-aging hormones like human growth hormone (HGH) by between 1300 and 2000 percent [19].
Prolonged fasting is scientifically linked to slowing down aging and extending longevity. One 2019 research discovered that time-restricted feeding with an eating window from 8 AM to 2 PM could potentially increase the autophagy and protein mTOR expression in the body.
When you fast, your body has less toxic materials flowing through the blood and lymphatic system, making it easier for you to think. While fasting, the energy you'd normally use to digest food is available to be used by the brain.
These are natural changes that occur while aging. They cannot be stopped but it is possible to slow the rate of these processes. This can be done by changing one's lifestyle (diet, exercise, etc). The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.
Science has shown for years that restricting the number of calories ingested while maintaining overall nutrition is a health-promoting lifestyle habit. It is associated with lower blood pressure and blood lipid levels, for one thing.
"Eat a lot of vegetables, good fats like tahini and avocado, and if you eat carbs, only whole wheat, oats and spelt," said Roseman. "Healthy nutrition generally prevents illnesses and slows aging in both the body and skin."
Moreover, since calorie restriction generally results in weight loss, less energy overall is needed to maintain the reduced body mass. As a result of this reduction of metabolic rate, it is hypothesized that calorie restriction could extend lifespans by decreasing the rate of free radical damage.
Older adults generally have lower calorie needs, but similar or even increased nutrient needs compared to younger adults. This is often due to less physical activity, changes in metabolism, or age-related loss of bone and muscle mass.
“Obesity incidence starts increasing in one's twenties and peaks at 40 to 59, and then decreases slightly after age 60,” says Craig Primack, MD, an obesity medicine physician at the Scottsdale Weight Loss Center in Arizona.
One of the primary reasons losing weight is harder to do as you grow older is due to a slowing metabolism. It is estimated that your metabolism slows down 5% every decade after you turn 40. This can occur because of the loss of muscle (or sarcopenia) which plays a crucial part in maintaining your metabolism.
This longevity is due to better health care and hygiene, healthier lifestyles, diet, and improved medical care. We have access to antibiotics and vaccines, clean water, plentiful and more nutritious food, and we know that exercise and smart lifestyle choices improve our quantity and quality of life.
