Since you've got no stress and no work you have the chance to change your diet completely. You can skip fast food since you have enough time anyways. If you want you can experiment a bit with food and cooking. Before every day, or every week if you want, have your schedule ready, what to eat, when and have it ready in your fridge. Build it around your training schedule and around your plans. Start with a good breakfast, with eggs if you want, fruits and some oats. After 3 hours have some fruit and water. Two hours later have your meal. Remember to drink plenty of water since you will be training a lot. Try to have enough protein as possible, especially before and after workout. Try to have one gram of protein every day per every two pound you weigh (if you weigh 200 lbs, consume 100 gr of protein). Try to include some fruits or vegetables in every meal, the greener the veggies the better. Chicken is always good for protein and creatine consumption. Have some healthy snacks 1-2 hours before you go to sleep. Pick a day during each week where you can eat what you want. Saturday is a good candy day, because usually people dont workout on saturday and its more acceptable. You will feel your body shocked and working through it. Dont worry, it will. On sunday you will be be dying for your veggies and your chicken.
