Despite “energy” being a fundamental physical concept like space and time, it’s not easy to measure directly in the human body. Yet every day we all have a subjective sense of our energy levels, and that impacts every aspect of life, from mood to alertness to productivity.
Our food choices obviously play a primary role in our energy, and unlike air, we have choices. Assuming enough calories, a plant-based diet can easily lead to a sense of increased energy, in all timeframes:
After a meal, during digestion, we all know the sluggish feeling from high-fat meals. But a low/moderate-fat plant-based meal is high in complex carbohydrates with a low glycemic index that keeps blood sugar levels, i.e. energy levels, more stable, while mitochondria (chemical power centers in our cells) activity can directly increase. Without excess saturated fat being dumped into your blood, circulation works efficiently; without endotoxins from meat and dairy taxing your gut and immune system, digestion proceeds efficiently.
In the longer run, on a WFPB diet you have plenty of glycogen stored in your muscles and liver to keep you going; your blood is less sticky/thick so circulates better through cleaner arteries; abundant plant antioxidants clean up the inevitable free radicals throughout your body (especially in your brain); and there’s little or no chronic inflammation that taxes your system.
When a clean, pure, whole food plant-based diet fuels the body so well, is it any wonder you feel good and energized?
