We all want to know how to live longer. In short, our lifespan is dependent on food intake, fat and body weight. Studies in the USA shows that lean people live longer. In those studies, the leanest women were found longest lived and the lightest men have the lowest mortality rate if they don’t have a condition of anorexia. Among them, those persons with 10% less of average body weight tables have the longest lifespan.
Our longevity depends on body fat specially on the waistline. The waistline fat of optimal health and longevity is given below:
Men: Not more than 1/2 inch near umbilicus.
Women: Not more than 1 inch near umbilicus.
If the waist fat is more than the above, they will have health problems. For health problems, read the article Causes and Risks of Overweight and Obesity.
From many studies, we know that mortality rate is higher as our body weight is heavier and heavier. So, it is worth to note the ideal body weight we should have. The approximate ideal weights of men and women are given below:
Men: 105 pounds upto 5 ft of height (5 pounds of every inch of height increase)
Women: 95 pounds upto 5 ft of height (4 pounds of every inch of height increase)
For example, if you are a male with a height of 5’7”, your ideal bodyweight is 105+(5*7)=140 pounds.
But the ideal bodyweight is considered as a rough calculation. In medical fields, BMI (Body Mass Index) is used. BMI calculation is done with the following equation:
BMI = Weight in pounds x 703 divided by Height in inch (squared)
If your BMI is over 24, you are overweight. If it is over 30, you are obese. But the BMI guide is not applicable to athletes and body builders. For athletes with a muscular body, waist measurement is good to consider. The waistline of men and women should not be more than the given below:
Men’s waist = Not more than 40 inches
Women’s waist = Not more than 35 inches
Fat deposits around your waist leads to health issues. If you are too much fat, you need to exercise and build muscles.
Another considerable thing is ‘Too Thin’. In case you are confirmed too thin by medical examinations, don’t eat too much to gain your weight. Eat when you are hungry. Overeating builds only fat but it leads to a shorter lifespan.
Have a healthy eating habit. Most people start losing their weight up to their ideal bodyweight, then it stops to stabilise your weight. Your weight stabilises when you attain a thin, muscular body. The stabilised weight gives you a true hunger for a healthy eating. Such a true hunger maintains muscles, not fat.
How to Increase Your Lifespan?
You need a weight loss plan and a dietary restriction – reduced calorie intake. Your diet plan of high nutrient, low caloric eating habit will increase your lifespan. From different experiments in several species like rodents, monkeys etc including human beings, researches find the reduction of health problems such as:
Resistance to cancers, delay in late life diseases, free of atherosclerosis and diabetes, low cholesterol and triglycerides, increased DHL (good protein), increased insulin sensibility, increased energy conservation, reduced oxidation, reduced ageing, increased cellular repairs, improved immune system, protected genes, slowed metabolic rate, etc.
You need fat and protein reduction. Higher fat and protein intake promotes increased ageing and tumor growth. Studies reveal eating less lengthens our life as long as we have an adequate nutrient intake. But there is no evidence overeating of nutrient rich intake prolongs life.
