If you're getting energy crashes with fruits and veggies throughout the day... then don't do it.
Try a more 'traditional' approach, like maybe Leangains and be sure to eat enough. I remember another thread where it looked like you were taking in ~1200 cals or something if I remember. That won't do the trick.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
