I also wanted to give you another perspective from an individual that I highly respect in the fitness world her name is @christinekambo she is a Specialist Musculoskeletal Physiotherapist. I asked for her thoughts and her comments are as follows:

“Some schools of thought are that if someone has eaten before exercise, they will access their immediate blood sugar stores before accessing their muscle and liver glycogen (glucagon) for immediate energy. After they have exhausted their energy supplies required for their ATP-CP energy system, then their lactic acid system, finally their aerobic system accesses their liver stores before burning fat. So if someone is trying to lose weight, why delay access to what’s already there by allowing the body to take the path of least resistance and go for the instant source: the bloodstream.

However, as we know, the actual PROCESS of eating boosts the metabolism. If this gets the whole metabolic cycle (Krebs cycle obviously delivering nutrients to where they are needed) moving, this will give the athlete more energy to perform better, stronger, faster etc (including carbs for the brain to increase agility, dexterity and concentration)… therefore making the workout more intense and boosting metabolism higher and for longer, which is what burns more body fat after all. Of course, timing and portion sizes need to be mentioned.”

Hope this helps?

Great question McMommy!
