Hi again, as a rather obese 48 year old sedentary woman (back issues, hypermobile joints, and a lifetime of RH which contributed massively (pun!) to the obesity), I am not the best person to advise on exercise.
BUT
I can tell you that the last 2 years on a ketogenic diet (much less than 50g carbs a day and fuelled by fat) I am fitter, slimmer and more active than I have been in 20 years. The ketosis gives me more energy, more stamina and better mental clarity than I ever had on carb-as-fuel.
If you are interested, have a look for a book by Volleck and Phinney 'The art and science of low carb'. There is one on general low carb living, and one on being an athlete. That should give you everything you need to know, including managing electrolytes and endurance stuff.
The general rule is that low carb is good for endurance and carbs are good for short term bursts. But having said that, my body does so much better on low carb, that I am better on BOTH than I was on carbs.
