After reading a great email from the lads over at @triagemethod
i thought i woild share the information a little further.
Basically, if you eat excess energy, it needs to be stored;
If we have an excess of dietary fat, that can be very easily stored right away with little effort.
whether we worry about sugar, or carbohydrates in general, we should be concerned with our total energy intake as the predictor of energy substrate use/storage. Fat is only synthesised from glucose, or stored (for good, leading to net fat gain) in an environment where we have a calorie surplus.
A calorie surplus means that we eat more energy/calories than we require, therefore the excess energy is stored within the fuel stores of the body.
What we must remember is that it’s not just as simple as saying “this is protein”, “this is a carbohydrate”, “this is fat” when predicting what actually happens in the body. There is an extensive “metabolic map” that looks a bit like the London underground, with hundreds of different pathways overlapping, all of which offer different fates for substrate “x”. The ingested pro/carb/fat do not simply remain as they were when ingested, but rather meet their fate in response to the contextual environment to which they enter.
It’s the energy content (calories) that determines whether or not excess energy is stored (chronically), which occurs regardless of where the excess calories come from.
Sugar isn't great for you but it's the calories that are the issue.
