One of the secrets to a healthy mind and body: Eat less
Researchers worldwide are pursuing various ideas to enhance the length and quality of our lives, and for a growing number of scientists, the answer is a simple change in diet.
Decades of research has shown that the key to age healthier is to reduce the amount of food on our plates, via an approach called “calorie restriction”.
This diet goes further than cutting back on fatty foods from time-to-time; it’s about making gradual and careful reductions in portion size permanently.
Studies conducted since the 1930s have shown that a 30% reduction in the amount of food consumed per day has been linked to longer, more active lives in worms, flies, rats, mice, and monkeys.
Across the animal kingdom, in other words, calorie restriction has proven the best remedy for the ravages of life. And humans have just as much to gain.
A study published in 2015 found very positive results. In the blood of calorie-restricted people, the ratio of “good” cholesterol to “bad” cholesterol had increased, molecules associated with tumour formation – called tumour necrosis factors (TNFs) – were reduced by around 25%, and levels of insulin resistance, a sure sign of diabetes, fell by nearly 40% compared to people who ate their normal diets. Overall, the blood’s pressure was lower.
In Islamic literature, many ailments have been associated with overeating.
There are many hadiths in Islam about the physical, mental and spiritual benefits of eating less, alongside sleeping and talking less.
Eating less means moderation, so that nutrition is based on the body's needs. By observing moderation in eating, we will be safe from the harms of overeating and various diseases, and we will enjoy the health of body and soul, God willing.
