Recently, I made an interesting observation during a conversation on the universal topic of eating habits. Most of the working population made a common comment on their diet. They all had bigger appetites and worried a lot less about what they put into their systems when they were younger.
While I am sure that most people would agree to this notion, it also happens to be scientifically true. Several research studies have found that there is a 1-2% decline in metabolism
(process of breaking nutrients for creating and using energy) every decade after the age of 20.
This decline rate becomes more rapid past 40 years for males and 50 years for females. Simply put, all our biological systems are naturally on the decline as we grow older.
Cold hands and feet, a tendency to feel the chill and patchy skin can all be signs of slow metabolism
. When many people hear that their metabolism may be slowing down, their first step is often to diet harder, and train harder, which is more likely to aggravate the problem. There are many sources of more detailed information on age related metabolic decline available online. A good article on it can be found here
In order for the powerhouse in each of our body’s cells (the mitochondria
is responsible for energy production) to function optimally, it wants plenty of all three macronutrients in the diet: protein, fat, and the infamous carbohydrates
A diet or exercise routine that significantly depletes carbohydrates or severely restricts one of these macronutrients can be very metabolically damaging. In fact, a research study by the American college of Nutrition in 2000 showed evidence that a diet low in saturated fat and high in carbohydrates and fiber gave the greatest health benefits in the long term.
A sluggish metabolism can also be represented by weight gain, dull skin and hair, fatigue, mood swings, low libido, poor digestion, and reduced fertility. Without the energy to perform every function optimally, your body will begin to make sacrifices on energy usage, and that is when these symptoms will begin to emerge.
