"Anything new is challenging or different," she said. "But it becomes second nature very quickly."
She advises dieters to envision the end result, just like one would envision arriving at a travel destination.
"I think you have to have your mind set in place," she said. "What does the end result look like?"
Once a goal is determined, Reno said individuals must prepare their surroundings to support that goal.
"Clear your cupboards of all junk foods and then start planning healthy meals and shopping for clean food," she said. Reno's books contain meal plans, grocery lists, recipes and motivational tips to help.
Always having clean food available is key, Reno said.
"When you're cooking dinner, double the recipe and pack the extra food for the next day's meals -- I call these 'planned leftovers,' " she said. "This will make it super easy to just grab a healthy meal when you're pressed for time. Also, when you leave the house, make sure you take a cooler filled with your healthy meals for the day."
Reno suggests setting weekly and monthly goals and writing them down. "People who write down their goals are 50% more likely to succeed."
Whether easing into the Eat-Clean Diet or diving head first into it, Reno said it's important for dieters to be committed to the process.
"You're never going to get to your goals unless you're willing to do what you need to do to get there," she said.
The most important way to achieve those goals is to manage time properly, Reno said.
"Plan your meals and training sessions for the week and try to delegate chores whenever possible. Once you get into a routine, you'll realize that the whole process is not as hard as you imagined."
