Scientists have found that the secret to significantly prolonging life by reducing calorie intake lies in lower metabolic rates. This is the first time humans have found a link between calorie restriction and lower metabolic rates.
Recently, scientists have done a lot of research to limit human calorie intake. In the study, they monitored 53 adults for up to two years.Thirty-four of them were on a strictly controlled diet, with 15 per cent less calories than their recommended daily intake. Since previous studies of calorie restricted diets have been conducted, it is certain that subjects will show positive signs of health, and that their blood cholesterol and glucose levels are indeed at better levels.
Even more striking, another relevant factor was found in the experiment. The subjects’ nocturnal metabolic rate decreased by 10 and their body temperature dropped significantly. After studying these numbers, Redman found that reduced metabolic rates during sleep also reduced cell oxidative stress by 20%. That’s the key, because metabolism is an important activity to keep people alive-it turns food intake into energy. But faster metabolism means more cell depletion, which means more oxidative stress, which is the main cause of aging in the long run. So reducing calorie intake can help our bodies better conserve energy and thus slow down aging. One of the best times to save your energy is to sleep, so it makes sense to adjust your metabolic rate when your body chooses to sleep by taking fewer calories. That’s why some animals hibernate.
Of course, lower metabolic rate can also lead to laziness, decreased libido, often feel cold, this is normal. Calorie restricted diets are not necessarily for everyone, so it is important to determine that any restricted diet does not affect a balanced intake of nutrients. No matter how many calories you consume, a balanced diet is the most important thing.
