Zero or Low Sugar Diet


The fitness and glamour industries must be credited for the popularity of zero or low sugar diets. If you have a great deal of body fat and want to loose some, or if you are a diabetic patient, such diets are great strategies. Otherwise, they could be suicidal since you end up cutting off the primary source of energy.

Remember that the brain, the central nervous system and the red blood cells are totally dependent on sugars for energy1. You simply cannot afford to have no sugar in your body.

When it comes to a low sugar diet, the question is: how much sugar is "low sugar". The answer is it depends: if you have a great deal of fat, 0 sugar is fine. But if you have low fat levels, low sugar should be the amount that is required for your physical and psychological activities. These are extremely difficult amounts to calculate since different people have different metabolism. Psychological process are almost immeasurable.

Therefore, it is better to have a slight excess of blood sugar than its deficit in the body. The excess sugar will be stored as fat for future use. This is how humans evolve — your biological functions convert excess sugar to fat and store it for future needs instead of filtering it out as a waste product.

There is a conflict between the perspectives of what human body and fitness is and what evolution has dictated human body and fitness to be. The fitness industry sells you insecurity, disinformation and products that are redundant (or useless). They do this because this is the only way you will pay them for something you could have gotten free by following a lifestyle that humans have been following for thousands of years.
