For obese elderly people, reducing the intake of 250 calories a day plus moderate exercise can get a greater return than just exercising
.

A new study published a few days ago in "Circulation" shows that in the elderly with obesity, compared with simple exercise or exercise plus a stricter diet, aerobic exercise is combined with a moderate reduction in daily calories.

Modifiable lifestyle factors, such as a healthy diet and regular exercise, may help counteract the increase in age-related aortic stiffness
.

Although aerobic exercise usually has a good effect on the structure and function of the aorta, previous studies have shown that exercise alone may not be enough to improve aortic stiffness in obese elderly people

"This is the first study to evaluate the effect of aerobic exercise on aortic stiffness with and without calorie reduction.
We obtained detailed images of the aorta through cardiovascular magnetic resonance imaging (CMR)
.

This randomized controlled trial included 160 sedentary obese adults, aged 65 to 79 years.
The average age of the participants was 69 years, 74% were women, and 73% were white
.

Participants were randomly assigned to 3 intervention groups for a period of 20 weeks

Under the guidance of a registered dietitian, the two calorie restriction groups received pre-made lunch and dinner, in which the calorie content of fat did not exceed 30%, and the ideal body weight protein was at least 0.
8 grams per kilogram; they were based on the menu approved by the dietitian Make your own breakfast
.

During the 20-week study at the Geriatric Research Center of Wake Forest Medical School, everyone involved in the study performed aerobic exercise training under supervision, 4 days a week

CMR evaluates the structure and function of the aorta to measure the aortic pulse wave velocity (PWV, the speed at which blood passes through the aorta) or the ability of the aorta to expand and contract
.

A higher PWV value and a lower dilation value indicate that the aorta is hardened

It was found that during the 5-month study period, a weight loss of nearly 10% or about 20 pounds was associated with a significant improvement in aortic stiffness, which only appeared in the exercise plus moderate calorie restriction group of participants
.

Other findings include: the expansion rate of the exercise plus moderate calorie restriction group increased by 21%, and the PWV decreased by 8%; no matter in the exercise-only group or the exercise plus stricter calorie restriction group, the aortic stiffness measurement did not change significantly; and Compared with the exercise-only group, the calorie restriction group had greater changes in BMI, total fat mass, body fat percentage, abdominal fat, and waist circumference; although the calorie intake of the strict calorie restriction group was nearly doubled, there were two calories The weight loss was similar between the restricted groups

"These results show that, relative to stricter or no calorie restriction, combining exercise with moderate calorie restriction may maximize the benefits of vascular health, while also optimizing weight loss and improving body fat distribution
.

" Brinkley added, “Stricter calorie restriction may not be necessary.
