We have quite a few CFB members signed up for the June nutrition challenge and a great way to approach the challenge is to commit to sustainability. Change eating habits towards something you can sustain and adapt to after this month, be realistic and experiment with Paleo, Zone or any others. Make basic good decisions like no sweets, more vegetables and the challenge helps add in a component of encouraging others to avoid temptations.
One thing that I think you see with any high level athlete or even the day-to-day fitness buff is they have some pretty serious rituals. These rituals help them to sustain a low body fat percentage and a high level of performance in the gym, no matter if they are a bodybuilder, crossfitter or powerlifter. I tend to see that many of us just have the wrong rituals, without thinking we eat sweets after dinner, maybe just one. Or at the ball park a Dr. Pepper sounds good or grab a few bites of your kids nachos. These are all rituals that we participate in without thinking about it.
Its taken me about 10 years to form some rituals that I don't even notice anymore. Like taking fish oil before bed or my pre-work out ritual of eating a Lara bar or an apple exactly 45-60 minutes before my workout. A more recent ritual of mine includes taking about 20 minutes of my evening to prepare my breakfast, snacks and lunch for work the next day. Cook 3-4 eggs, salsa, sausage, 1/4 cup oats with some whey, apple, snack bar, almonds, dinner leftovers for lunch and done. I like to turn on the radio and get in my own zone for a little bit while I get everything together, wrap it in a Wal-mart sack and I'm ready to go!
After some time those "bad" rituals get replaced with some good ones. A ritual is a day-to-day or week-to-week thing you can do to keep going at a nice, steady and sustainable pace. In the video below Christmas Abbott does an interview with CBS News, a key point she makes is she has the exact same breakfast every morning. It may sound boring, but its not a chore to her - its a ritual and the structure helps her attain an end goal of being an extremely fit and athletic person!
