Our weight gain or our weight loss is a lot more about our metabolic rate rather than consumption of food, our intake of liquids or even the amount we exercise.
Our metabolic rates vary con-siderably between the sexes and individuals; since it is gener-ally accepted that our metabolic rate is the key to managing our weight and all of the health implications that may impact on our longevity and quality of life. Having said that the amount we eat may not be the reason for weight gain, what and how we eat, also our diet may have a significant effect on body function, especially metabolism.
So what is metabolism? We hear much about metabolic rate for different individuals. Metabolism has its origins in the Greek word (metabole) meaning change. Metabolism is the chemical transformation within our body’s system that involve enzyme action that converts cells (food) into a form that can be used by our body’s and converted into energy. Our metabolism oper-ates in two main ways: catabolism for the breaking down of or-ganic matter and anabolism that uses energy to construct cells to form proteins and nucleic acids. Understanding metabolic function is key to managing our weight and enjoying all of the benefits healthy weight adds to our quality of life.
I am sure you are all aware of the myriads of diets including the fads, the extremes and the sensible; so if metabolism is the key and what we eat and how we eat can effect metabolism, the types of foods that help promote healthy metabolism are fibre in the form of leafy green vegetables, celery, whole grains, nuts and basic unprocessed old fashioned fresh foods.
The glycemic index is a good guide; the low GI foods are the ones we need to tend towards. Artificial sweeteners are low in calories but may contribute to weight gain; high fat and high sugar foods can mask the signal that we have eaten enough and release chemicals that make us crave more of these foods.
