While I would contend that there is no true secret...I will tell you that I think there are tricks that make eathing healthy easier, thus making it easier to to become a true part of your day-to-day habits. Today, I thought I would share with you my favorite trick:
Make healthy foods as easy to eat as a bag of Cheetos.
I can't tell you how many times I justified by previous eating habits by saying "I'm so busy, I don't have time....I travel for work, it's so hard...blah, blah, blah."
Here's how to make it easy. Every week, I go to the grocery on the weekend and buy my standard batch of fruits and veggies: Grapes, Apples, Baby Carrots, Green Peppers, Clementines (if in season), Berries (if in season), Celery, etc.
When I come home from the grocery I take about 1 hour and I get everything ready for the week. I clean the grapes and put 1 cup in each bag. Clean the peppers and cut into strips. Put 10 baby carrots in each bag, Slice the apples (I do this the night before). Also pictured is my favorite "treat": part skim mozzarella cheese stick.
I put all these "to-go" bags in the bottom of my fridge, so that I can quickly grab them in the morning and throw into my lunch bag.
I also swear by these little 1 cup ziploc containers: Size XS. 
I take the leftovers from dinner and portion out a lunch size portion for the next day:
I also use them for cottage cheese, homemade soup, etc. Also, I throw in a yogurt for good measure....and don't forget a piece for my sweet tooth!
I take these with me during the day. If I'm traveling I take all non-dairy items with me in my purse. I always make sure I don't go longer than a few hours without a snack. I can't promise that this will work for everyone, but for me it made all the difference in the world!
