On a fast day I try to hold off on my breakfast of a boiled egg and oatcake until about 11am. On a non-fast day my breakfast is the same, but I also wait as long as possible because I find when I start eating I don't stop! Until my first bit of food for the day I have lemon and ginger water or tea with milk. I don't struggle to work out on an empty stomach.
But am I not burning as much fat as I would if I had my egg and oatcake pre-workout?! Should I have a bit of protein straight after? All the sources online say different things.
