First off there is absolutely nothing wrong with lifting on an empty stomache. I do it and I grow like a weed. I do it 1 hour after waking in the morning after drinking 1/2 pot coffee.

She is not doing to much cardio. This is my shedule for a keto diet.

Sun-Upper body workout. 30 min cardio after.
Mon-Lower body workout. 30 min cardio after.
Tues-thur cardio 1 hour after waking up for 45 min.
Friday-whole body depletion workout followed by 36 hour carbup.

I actually put on muscle mass durring this diet. I am in ketosis by tues morning. I am very knowlegable about putting on muscle mass. This is also the best way for me to lose fat.

I would also point out that eating fruit is a big NO NO when carbing up. YOu will most likely store it as fat. Fructose is used by liver and then when it is full it will store as fat. The carbup is just as important as the diet itself. I would stay away from any junk. I know this as I have done keto diets for over 9 years now.
