A combination of things happens as we age. We tend to lose muscle mass, so our abdominal muscles aren't as tight as they once were, and the loss of elastin and collagen in our skin allows gravity to have its way so skin starts to sag. Both can cause the waistline to expand.
An expanding waistline is sometimes considered the price of getting older. For women, this can be especially true after menopause, when body fat tends to shift to the abdomen. Yet an increase in belly fat does more than make it hard to zip up your jeans. Research shows that belly fat also carries serious health risks.
"We found older people really are wider, almost 8 to 9 percent wider," Dahners said. "An almost 10 percent increase in your circumference if you consider yourself to be a cylinder would be enough to explain a big part of a pound a year gain over the age of 20."
A growing waist may be the result of a poor diet and unhealthy eating habits. If you are consuming more calories than you burn, you will gain weight. Not only does the amount of food you consume affect your waist size, but the kinds of food you consume are equally important.
As you age, your muscle mass decreases and your fat mass increases. Fat is less metabolically active than muscle—you don't need as many calories to maintain fat as you do to maintain muscle. Hormonal changes can also lead to weight gain.
Those extra pounds were packed on in early adulthood: The average American gained about 17.6 pounds from their mid-20s to mid-30s, the study found. Meanwhile, the average person gained about 14.3 pounds between their 30s and 40s, 9.5 pounds between their 40s and 50s, and 4.6 pounds between their 50s and 60s.
Getting older
A person's body composition changes as they age, which can lead to a belly bulge. For females, the decrease in the hormone estrogen during menopause triggers an accumulation of body fat.
Eating a healthy, varied diet that is high in fruits and vegetables — including soluble fiber, vitamin D, and probiotics — is the best plan for losing weight from your waistline. Avoiding refined carbohydrates, sugar, and processed foods whenever possible will help you cut calories and get rid of fat more quickly.
Why We Gain Weight As We Age It starts sometime during our 50s and 60s: that belly bulge, those "extra" pounds we just can't seem to shed. Part of it is simply the biology of our bodies. Our muscles literally shrink as we age, and that means more calories turn into fat — and it's a lot harder to exercise it off.
Most people begin to notice a shift in the appearance of their face around their 40's and 50's, with some also noticing a change in their 30's. But with these physical changes brought on by aging also comes a change in the appearance of our face - Luckily, there is treatment available.
The authors point to estrogen levels, which rise during puberty and decline later in life, as the likely cause of the widening and subsequent narrowing in the female pelvis, in particular because estrogen is known to impact bone growth and development.
As you age, having a more sedentary lifestyle, changes in hormones and a natural loss of muscle mass makes it more likely that your waistband will expand. To lose belly fat, it's key to combine physical activity and a lower calorie diet that's focused on unprocessed foods.
For people under 40, a waist to height ratio of over 0.5 can be critical, while for people between 40 and 50 years of age, the critical value is between 0.5 and 0.6. For people over 50 the critical value begins at 0.6.
One of the most effective ways to reduce belly fat is to regularly take part in aerobic exercise, such as walking ( 19 , 20 ). In one small study, women with obesity who walked for 50–70 minutes three times per week for 12 weeks, on average, reduced their waist circumference and their body fat.
The side plank with hip lifts activates the obliques and helps to build endurance and core strength. This exercise works the deep abdominal muscles and helps to tighten and shrink the waistline.
How quickly will you lose weight? The volunteers reduced their waist sizes by an average of 1 inch for every 4lb (1.81kg) they lost. So if you lose 1lb (0.45kg) a week you could hope to reduce your waistline by an inch after four weeks.
We tend to lose muscle mass, so our abdominal muscles aren't as tight as they once were, and the loss of elastin and collagen in our skin allows gravity to have its way so skin starts to sag. Both can cause the waistline to expand.
There are many reasons why people gain belly fat, including poor diet, lack of exercise, and stress. Improving nutrition, increasing activity, and making other lifestyle changes can all help. Belly fat refers to fat around the abdomen.
The most common causes are trapped gas or eating too much in a short time. The sensation of bloating can cause abdominal distention, which is a visible swelling or extension of your belly.
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. Consequently, as you age you may not be able to maintain the same dietary behaviors without gaining weight.
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.
The speed that your body burns energy for its everyday functions is called your metabolic rate. For most people, this doesn't start to slow down until around the age of 60, but it does change if your weight changes.
