Calorie restriction tied to reduced blood pressure, cholesterol and insulin resistance, among other health factors – To live longer, you may want to eat less.
A new study found that patients who reduced their total calorie intake had reduced blood pressure, cholesterol and insulin resistance — all factors tied to life span.
“It is encouraging to find positive effects when we test interventions that might affect diseases and declines associated with advancing age,” said Richard J. Hodes, MD, director of the National Institute on Aging (NIA), in a press release.
“However, we need to learn much more about the health consequences of this type of intervention in healthy people before considering dietary recommendations. In the meantime, we do know that exercise and maintaining a healthy weight and diet can contribute to healthy aging.”
Calorie restriction is all about reducing daily calorie intake without depriving the body of essential nutrients. In other words, reach for the fruits, veggies and healthy proteins — not sugar-laden empty calories.
And plenty of past animal studies have found positive effects of calorie restriction, but this is among the first randomized, controlled trials to test the effects in humans, according to the National Institutes of Health.
To do so, study author Evan C. Hadley, MD, director of the NIA Division of Geriatrics and Clinical Gerontology, and colleagues asked some of the study patients to restrict their calorie intake for two years. The other patients — the control group — did not change their diets.
On average, the calorie-restriction patients lost 10 percent of their body weight over the course of this study, Dr. Hadley and team found. They were also able to reduce their calorie intake by around 12 percent. Control group patients saw little to no change in these measures.
In addition to their reduced weight, patients who restricted their calorie intake also saw improvements in health measures tied to longevity. Those included a 4 percent drop in blood pressure, a 6 percent drop in cholesterol and a 47 percent drop in C-reactive protein.
High cholesterol and blood pressure have long been tied to an increased risk of heart disease. The same goes for C-reactive protein, which is a blood marker that signals inflammation.
Calorie-restriction patients also saw declines in insulin resistance. Resistance to insulin, the hormone that regulates blood sugar, is a risk factor for type 2 diabetes.
This study was published in the September issue of the Journal of Gerontology: Medical Science.

Calorie restriction is useless unless you do it the healthy way. A Calorie is not just a calorie, because you do get “good” calories and “bad” calories. Try to follow the Manna Diet, restrict or eliminate soft drinks, fruit juices, all white starches and potatoes (“bad calories”).
You will crave for sugar when switching from high carbohydrate diet to low carbohydrate and therefore we recommend that you take the Manna Blood Sugar Support Supplement with each meal to control food and sugar cravings, and suppress appetite.
Calorie Restriction Testimonial
Jeremy Davis is 28, is 185cm, and weighs 93kg. But in 2010, he was double his current weight, at 186 kg. This is the story of his weight-loss journey.
The Turning Point
My first memory of knowing that I was overweight was in first grade. The teacher would ask us to put our heads down on the desk, and me being so heavy, I was unable to do it. I knew I was well beyond what I should weigh throughout my childhood and adolescence — I weighed over 91 kg in the fifth grade and 136 kg by the time I got to high school. But it wasn’t until years later, in July 2010 when I went on a mission trip, that I truly knew that something had to change. I was at my breaking point. It was just too hard to keep up with everything and everyone. So, the day we returned, my weight-loss journey began.
At first, my goal was to make small changes. I cut out fast foods and fried foods, and began walking for an hour a day, four to five days a week. As I started dropping more and more weight, though, I would hit plateaus where the losing slowed or stopped, and then I had to become stricter about the foods I ate. This is what led me to calorie counting, which helped tremendously.
Slowly, I came to realize that it was important to choose not only light foods that helped me lose weight, but ones that were healthy and good for me, too — like choosing a grilled chicken salad instead of a processed frozen dinner, even if both had the same amount of calories. Eating well made me feel better.
After the first 45 kg were gone, running and weight training became staples in my life. My goals were no longer about weight loss, but performance. I started setting goals to run 5Ks and mud runs, or to do a set number of pull-ups — those motivated me more than any number on the scale.
Today, I’m very mindful of how many calories I consume. I like to eat, and I can eat a lot, so I try to fill my diet with lower-calorie, higher-volume options. For instance, an 80-calorie apple is a much more filling snack than the handful of potato chips that clocks in at 180 calories. In general, I eat lots of fresh fruits and vegetables, homemade salads (restaurant ones can pack in the calories!), skinless chicken, lean steaks, fish, and whole grains.
