Commonly, when we want to lose weight we go on a “diet”. We often define diet as a reduction in food intake however, the definition of diet, according to the “Concise English Dictionary”, is “Mode of living, now only with especial reference to food.” So, diet is really lifestyle. When we say we are going to go on a “diet”, that carries a negative connotation that one must starve one self in order to lose weight. In fact, what one really needs to do is to make a lifestyle change. A lifestyle change which promotes healthier eating while improving our physical and, subsequently, our mental well being. Let’s face it, nothing improves our mental and emotional well being as seeing our reflection of our ten pound lighter selves.
Before you start your new diet you need to have a general understanding how our bodies convert food into energy and how it stores unused energy for future use. Glucose, or sugar, converted from ingested carbohydrates, is your bodies preferred source of energy, (or fuel), during daily activity. The average adults cardiovascular system has the capacity to maintain approximately 80 calories of blood glucose. When blood glucose rises beyond this level, insulin is released carrying excess glucose back to the liver where blood glucose is converted into it’s storage form, glycogen. Our liver is capable of storing 300-400 calories of glycogen. Once the liver stores are full, insulin carried glycogen is carried to muscles which require glycogen for repair from previous, strenuous activity. The final destination for excess, unused glycogen beyond this point is adipose fat tissue. So, in short, carbohydrates consumed in excess ultimately get stored INSIDE your adipose, or fat tissues as triglycerides.
Now, before you stop ingesting carbohydrates all together and throw on a pair of running shoes to burn off all that excess adipose fat tissue, let’s slow down and talk about this a little more.
We now know ingested carbohydrates are converted into energy. We also know our cardiovascular system stores approximately 80 calories for immediate energy needs. So, instead of ingesting large amounts of carbohydrates three times daily, we should ingest smaller amounts more often so we can slowly replace our depleting blood glucose levels due to daily activity while preventing excess fuel storage in the form of triglycerides which reside in our adipose fat tissues.
So, don’t go on a “diet” and starve yourself. A prolonged, low calorie diet will lead to a slower metabolism and most likely will contribute to weight gain.
In my next blog I will follow up and explain why resistance training is critical to a successful weight loss program which will improve your overall body composition and increased weight loss.
Until then remember, “If you want it, you have to go get it.”
