For tens of year doctors stated that eating less is very beneficial for the body, as it increases the lifespan and it prevents certain diseases from occurring. It is unknown if eating fewer calories increases one’s life, but it is certain that it has its benefits.
Only Overweight People Should Attempt It
Scientists are interested in this subject, and they are trying to see if reducing the number of calories can have certain benefits on different conditions, such as strokes, diabetes, asthma, and others.
According to Mark Mattson, a neuroscientist at the National Institute on Aging in Baltimore, reducing the number of calories could prevent the development of Alzheimer’s disease. He stated that only obese or overweight people should reduce practice caloric restriction, as it is unknown if the benefits can be seen in the case of the thin people.
Mattson and his colleagues discovered last year that caloric restriction has the possibility of reducing cancer risk amongst overweight women.
Women who ate 25 percent less calories than they needed, reduced the inflammation and levels of hormones which cause breast cancer.
In 2007, Mattson conducted a study on 10 overweight people who suffered of asthma. They were asked to consume a calorie-restricted diet of 500 to 600 once every two days. In the days when they didn’t diet, they could eat whatever they wanted, and as much as they desired. After 8 weeks, they stated that their asthma symptoms improved.
Caloric Restriction Might Reduce Neurological Damage
The scientists also discovered that a caloric restriction in animals reduces the neurological damage which occurs after a stroke. However, only the young and the middle aged animals benefited from the diet. It seems that a restricted calorie diet can also help people with spinal cord injuries.
Caloric restriction could also be good for the people who are in the risk of developing Alzheimer’s disease. Mattson said that exercising the nerve cells prevents the development of the disease, and one of the best ways of putting the brain cells to work is by reducing the amount of calories you consume.
When you consume fewer calories than you need, the brain cells will be put under stress, which will exercise them.
When they tested the mice, the ones that consumed fewer calories than they required, they were able to perform much better at the memory tests. On top of that, they also had less amyloid beta aggregates in the brain.
Amyloid is considered to be the main factor which causes the development of Alzheimer’s disease. Mattson said that not all diseases or illnesses benefit from caloric restriction. There are some who accelerate when one does not consume the amount of calories he/she should consume.
For example, people who have Lou Gehrig’s disease or amyotrophic lateral sclerosis should consume the proper amount of calories. It is unknown if the theory is true, as they will need to perform more tests.
