THE PALEO DIET

Paleo The paleo or “caveman” diet focusses on eating food which was available to our ancient ancestors. This essentially means no processed foods, really no foods that aren’t more than 10,000-ish years old. That means no sweets, no sugar, and no bread. The diet is mostly based on meat, fish, fruit, vegetables, eggs and nuts…

CARBOHYDRATE ENERGY: USAGE, STORAGE AND COMPETION

Glycolysis Glycolysis means the breakdown of glucose. If we break down the word this makes sense; “Glyco” = glucose and “lysis” = splitting. What we split glucose down into is something called pyruvate, which can feed into the Krebs cycle, to make ATP energy. Energy storage If we take in more glucose than we need…

METABOLISM PART 2: THE KREBS CYCLE AND OXIDATIVE PHOSPHORYLATION

In the metabolism part 1 post, I discussed why the body can use any of the three dietary macronutrients we eat to produce energy. Any macronutrient can lead to energy because they are all ultimately broken down into Acetyl-CoA and fed into something called the Krebs cycle. The Krebs cycle then uses Acetyl-CoA to produce…

METABOLISM PART 1: METABOLIC FLEXIBILITY

Our bodies have a significant amount of metabolic flexibility. That means we can utilise any of the different macronutrients, fats, proteins or carbs, to produce energy. There are essential proteins and essential fats, but there is no such thing as an essential carbohydrate, so we could survive without any carbs whatsoever! You can see that…
