|Most Westerners would benefit from eating fewer calories, and eating better food.|
What if health experts are as wrong about how many calories we need as they are about our food pyramid and the types of foods that are best for us? I suspect that we have been scammed so that we eat not only the wrong foods, but also eat more food than we need.
How many calories does a person need to be healthy? It depends on the individual, and it depends on who you ask.
"Health authorities around the world find it hard to agree on how many calories their citizens should ideally consume. The US government says the average man requires 2,700 calories per day and the average woman 2,200, while the NHS (National Health Service), UK, says it should be 2,500 and 2,000 respectively.
The FAO (Food and Agriculture Organization) of the United Nations says the average adult should consume no less than 1,800 calories per day."
Below are the caloric values of the three main components of the food we eat:
1 gram of carbohydrates contains 4 calories
1 gram of protein contains 4 calories
1 gram of fat contains 9 calories.
A restricted caloric diet may slow aging and extend lifespan. It improves the health of a variety of species including yeast, earthworms, fish, rodents, dogs and rhesus monkeys. Why not humans too?
Scientists do not yet know if such results are applicable to us, but it is likely that eating fewer, better calories will yield health benefits.
