I am reading Thrive – The Vegan Nutrition Guide to optimal performance in sports and life by Brendan Brazier (link). The book is very interesting but I found the section about nutrition before exercise, really interesting so I thought I would share the details.
There seems to be a new school of thought that protein loading before intense exercise instead of the carbohydrate loading, which used to be the pre-exercise preparation of choice.
“Eating too much protein before intense exercise will likely result in muscle cramping, since protein requires more fluid to be metabolized than carbohydrate or fat, and cramping occurs when the body is not properly hydrated. Also, protein is not what you want to have your body burning as fuel. Protein is for building muscle, not fuelling it.
When protein is consumed in place of carbohydrate immediately before exercise, and therefore burned as fuel, it burns “dirty”, meaning that toxins are created from its combustion. The production and elimination of toxins are a stress on the body and can cause a stress response, ultimately leading to a decline in endurance.” – Chapter 4 – Exercise for lifelong health (P108)
Too much protein is very bad for your kidney and liver and when I refer to healthy options of protein, it is always plant-based.
