Kim and Khloe Kardashian's Diet and Fitness Secrets Khloe Kardashian says she’s super happy with her new body and big sister Kim Kardashian says that she is in the best shape of her life.

The Keeping Up With The Kardashians star, Khloe says she started emotionally eating when her parents, Robert and Kris Kardashian, were going through a divorce and her weight has been a roller coaster ever since then.  According to Khloe,

“I was anorexic when I was 15  I’d be obsessed with working out, and I’d never eat.

That was the worst I’ve ever been. I’ve been very underweight and then overweight by about 30 pounds.”

Big sister Kim has too dealt with struggles, with her own weight, fluctuating up and down over the years.

Kim says she has always been happy with her curves but is now even happier living a healthy and fit lifestyle.

To shed the weight, Khloe enlisted the help of sister Kim and worked out about 45 minutes a day, five days a week, and maintained a balanced, practical diet.  As a result, she shed 20 pounds from her 5-foot-9 frame over four weeks!  Kim has since released her own workout video line, "Fit in Your Jeans by Friday", which is a fitness top seller.

Train with a friend- Like Khloe, she admits that she could not have lost the weight without the help of big sister Kim.  Saying ” “We both have a sweet tooth and keep each other’s snacking habits in check. Just having someone’s encouragement makes it so much easier.”  Having the support of a family member, friend, or co-worker will make staying focused and on track so much easier.

Keep a food journal- Over the next week, write down everything that you take in and you will probably be surprised how many extra calories that you are consuming.  Hold yourself accountable by writing down your goals and sticking to a balanced, practical diet that you can keep track of in your food journal.

Prepare your schedule and food in advance- If you want to find time to go to the gym than you have to make time.  Plan out your days and weeks in advance and always schedule in time for you to work-out.  Same goes with food preparation, prepare your food in advance for packing and on the go meals.  It is much easier to stick to a nutrition program when you have food with you and prepared.

If you mess up, don’t blow the rest of the day- We are all human and make mistakes or give in to tempting cheats every now and then.  It is what you do after the cheat that will determine your success.  Never have two bad meals in a row, if you mess up, get back on track during the next meal.
