In reply to Francine.

Some people do choose to eat a higher carb day throughout their week or month, that they call a carb-up or carb-load. During this time, they only eat "healthy" carbs, as in, starchier vegetables like sweet potatoes or sometimes quinoa or rice. They don't load up on sugary sweets or nutritionally empty pastas. We can't vouch for this method for health or weight loss as we've never tried it, but this website www.fitlivingfoodies.com has a lot of information on the subject :)

As for intense workouts, many people report having higher stamina while fully keto so that should work in your favor. Try it!
