This celebrity trainer doesn't mess around when it comes to her diet and exercise routine. Read on for the best advice that Jillian Michaels has to offer. 

1. Cut out processed foods.
"I eat a very balanced ratio of protein, fats and carbs and most importantly I have removed chemicals from my diet," says Jillian Michaels, personal trainer on The Biggest Loser and creator of Goodlife Fitness's Bodyshred class. Michaels aims for minimally processed foods in her diet. Some of her current favourite treats include beef jerky (a special brand made without artificial ingredients) and frozen broccoli for quick and easy meals.

2. Give up booze.
"I don't drink much, so for me a glass of wine or a shot of tequila is a pretty big indulgence and one of the worst things you can do for your metabolism," says Michaels. "That's a flat out cheat. I love an IPA but I drink one maybe twice a month." Calories in alcohol not only add up fast, drinking alters your blood sugar, making you crave more unhealthy snacks and while your body is processing the toxins, it's not focusing on processing fat.

3. Rethink your post-workout treats.
"You can eat your way through any amount of exercise," says Michaels. "Make sure you're using common sense and counting your calories with your food or you can easily wipe out your fitness efforts." Her ultimate advice? "Don't eat more calories than you burn in a day." Use a food diary app to track your caloric intake and stock up on some healthy snacks.

4. Push yourself harder at the gym.
"My number one fitness tip would be to work out at 85 percent of your maximum heart rate," says Michaels. "Most people don't work out as intensely as they are capable of. This is unique to the individual because what will get you to 85 percent is what different that will get me there," she says. Use a heart rate monitor to make sure you're getting in the zone during your workout.

5. Use the 80/20 rule and go organic when possible.
"Use common sense for your food choices 80 percent of the time," says Michaels. "Everybody knows that scrambled egg whites are better than a donut in the morning. Everybody knows Greek yogurt is better than a bagel. We're not dumb. So 80 percent of the time, make the intelligent food choice and 20 percent of the time allow yourself the treat foods. If you do that you're golden. If you have the resources financially go organic whenever possible to put the cherry on top of the sundae."

6. Find healthy motivators.
When asked how she stays motivated, Micahels makes it clear that her family is ultimately the reason she works so hard to stay healthy. "I have two little kids and I think about being around for them when they are my age," she says. "I have to walk the walk and talk the talk. That always keeps me in line. Last but not least, the feeling of being strong allows me to be more confident and empowered in every other facet of my life. I ask myself, how do I feel when I haven't been to the gym for two weeks and how do I feel when I have?" she says.
