I did not mean the rest of the week I sit around eating KFC. I eat clean, go to the gym several times a week, walk 2/3 hours daily. I could happily run a marathon tomorrow.
Being on a diet like Jake described is great, if you can stick to it, and afford to do it.
Eating like this, you will always be engaging willpower. Unless you are training to be a body builder and it's subconscious, eventually you will stop.
Like you say, eating a decent diet, exercising a lot is fine. People who eat like Jake is describing constantly are looking to get their body fat down to below 6% ish. You can still look amazing at about 10-12%, which is about where I'm at. Yes it would be nice to be less - but honestly, it's really not worth it, in my opinion.
Eat clean. Exercise a lot. You'll be amazed at the results. Eating clean is only half the battle.
What's you training schedule Jake?
