One of the world's most famous babies, North West, celebrated her first birthday with parents Kim Kardashian and Kanye West, reported People magazine on Monday. And Kim has another reason to celebrate: She lost 56 pounds and restored her pre-baby body with a high fat low carb ketogenic diet.
Sharing her joy in being a mom, Kim posted an Instagram photo and wrote: "This is what life is about! Our baby girl turned 1 today!"
But shedding her baby weight wasn't so joyful. Kim tweeted that she had gone on the high fat low carb ketogenic Atkins diet to lose her post-pregnancy pounds.
In a fan Q&A in March, however, Kim confessed that she had gained some weight back when she strayed from the low-carb plan. "I actually saw I gained some weight back when I saw pics of myself and started [Atkins] again," she confessed.
In an exclusive interview on Monday, we asked Colette Heimowitz, VP of Nutrition at Atkins Nutritionals, Inc., to discuss what's involved in the Atkins diet. She is the author of "The New Atkins Made Easy: A Faster, Simpler Way to Shed Weight and Feel Great -- Starting Today."
"The key to losing weight is lowering carbohydrate intake and replacing high sugar carbs with healthy fats," said Colette. "That includes monounsaturated fat like nuts, avocado, salmon, and olive oil."
A recent debate in the news over the pros and cons of saturated fats has caused some confusion. The butter brouhaha began with the publication of "The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet," which proclaims the virtues of high fat foods.
Although Colette notes that saturated fats such as eggs, cheese, butter and coconut oil are part of the Atkins diet, she recommends avoiding trans fats. The reason: They cause inflammation.
The key to high fat low carb ketogenic diets is shifting to fat-burning mode. "When carbs are low enough, the body will burn fat for fuel so you lose the extra fat you have stored on your body and you burn the fat you are eating for energy," Colette told us.
Colette also revealed that the Atkins diet recently has been improved to emphasize fiber intake. "Fiber makes us feel full sooner and stays in our stomach longer than other substances we eat, slowing down our rate of digestion and keeping us feeling full longer."
As a result, it's important to choose carbohydrate sources high in fiber. "To increase your intake of fiber, eat lots of vegetables, some berries, and some nuts/seeds," added Colette.
In addition to her diet, Kim works out regularly with her personal trainer Gunnar Peterson, according to New York Daily News. Gunnar, author of "The Workout: Core Secrets from Hollywood's #1 Trainer," emphasizes the use of weights for achieving derriere's like Kim's famous booty.
"If you want to enhance the shape of your butt, as well as tone and tighten, the most important exercises are squats and lunges," Gunnar told Shape magazine. "Be sure to use weights, weights, weights, and weights… and then some weights!"
