It is totally dependent on your goals!
If you are someone training for a specific sport or utilizing a training program that is super glycolytic, consuming carbohydrates pre-workout will likely benefit you.
For the majority of the population who is looking for fat-loss, “fuelling up” or eating carbohydrates before you exercise is actually something I recommend avoiding.
Your body already has “fuel” and can create it’s own energy sources if you give it the chance to.
If fat loss is your goal, the goal should be to have your body utilize stored fat and amino acids as fuel, rather than carbohydrates – aka a process called gluconeogenesis.
Basically having carbohydrates pre-workout means your body will use those free circulating carbohydrates for energy and not stored body fat.
Of course, it is important to know that if you are used to consuming high amounts of carbohydrates pre-workout, you will need to give your body time to adjust to exercising with a lower carbohydrate intake.
I personally train in the morning after having a coffee, and if I feel like I need an extra something something – I’ll add MCT oil.
