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…

IS CAKE ADDICTIVE?

The main components of cake, sugar, and flour, might have addictive potential. That could mean a situation where a cake is addictive! Sugar Sugar comes in many forms. More and more evidence is emerging to show that the refined stuff that’s on our tables and in our cakes is bad for our health. A 2007…

UNDERSTANDING MACRONUTRIENTS – PART 1. FAT

There are certain buzz words when it comes to our dietary intake, some of these have become almost dirty words – especially in the media. One such word is “fat”. However, most fat is not at all bad- in fact, it’s good for us, even essential! That makes understanding them necessary. Trans, unsaturated and saturated…

GETTING ENERGY FROM FAT – PART 1. LONG CHAIN FATTY ACIDS

DISCLAIMER – THIS ONE IS MORE SCIENCY-Y. Our body is impressively adaptable and can use a broad array of metabolic pathways to produce energy. If we think of our body as a car, our cells as the engine and food as our fuel, then we’re a bit like a hybrid. We can use multiple different…

METABOLISM PART 3: NUTRITIONAL KETOSIS

So far on this blog, I’ve discussed metabolism of the three primary macronutrients within the body and their metabolism under normal conditions, but sometimes they’re used a little bit differently if circumstances aren’t normal. An example of this would be a Ketogenic diet, which is a type of high fat, very low carbohydrate diet that…
