Kim Kardashian needs a rumor-vanishing version of “Ghostbusters.” The woman known primarily for her body (and her skills in spending money) had to go on the attack after rumors that she had turned to plastic surgery rather than the Atkins diet to shed her post-baby weight. Now she’s fed up with rumors that her famous derriere is actually the result of butt implants, reported On the Red Carpet Feb. 21.

“I’m seeing all these nonsense tabloids claiming I have butt implants-injections. Get a life! Using pics of me 15lbs skinnier (before I had my baby) comparing to me now,” scolded Kim.

“Anyone who has had a baby knows how hard it is to lose weight (especially the last bit of weight) & your body totally changes!” she added.

And to prove that her distinctive derriere has not changed, Kim posted a photo of herself on Feb. 21 with labeled “#FlashBACKFriday.”

Kim is so famed for her booty that she even stars in a series of fitness derriere DVDs, such as “Kim Kardashian: Fit In Your Jeans by Friday: Ultimate Butt Body Sculpt.”

Attacking tabloids who also reported that she had liposuction, Kim noted:

Making fun of me pregnant & making fun of me trying to lose weight now shame on you.

I’m not perfect but I will never conform to your skinny standards sorry! Not me. And BTW I’ve lost a lot so far & I’m proud of that! Don’t give young girls a complex!

Kim has repeatedly emphasized that she’s worked hard for her weight loss and inimitable derriere. Her high fat low carb diet follows the Atkins guidelines: It’s a ketogenic approach designed to boost fat-burning.

How much has she lost? In contrast to Jessica Simpson, who repeatedly has declined to state precisely how much weight she’s shed in her second voyage using Weight Watchers, Kim told Jay Leno that she was “50 pounds down.”

Since that appearance, she’s lost more weight and reportedly wants to lose more prior to her wedding.

Kim’s low carb diet includes “proteins like fish, poultry, and lean meats; healthy fats like avocado, nuts, and olive oil; lots of colorful vegetables filled with antioxidants and fiber; and low glycemic fruits like berries—essential foods for maintaining energy,” said Atkins diet expert Colette Heimowitz in an E News interview.

So you want to lose weight. What could be better than a diet plan created by one of the well-known physicians on the popular health talk show “The Doctors,” two of whom have created their own weight loss programs? The challenge in choosing one of those plans: Dr. Ian Smith provides very different diet tactics in his “Super Shred” diet when compared to Dr. Travis Stork’s “The Doctor’s Diet,” reported USA Today on Feb. 23.

Dr. Ian says he believes that the key to rapid weight loss is “calorie disruption,” and contends that his diet can help dieters lose 20 pounds in four weeks: “Super Shred: The Big Results Diet: 4 Weeks 20 Pounds Lose It Faster!”

The “Super Shred” weight loss program alternates calorie counts, up to 1,600 calories on some days and down to 900 calories on other days. Included are grocery lists, meal plans and recipes. Dieters are advised to perform 40 minutes or more of high-intensity interval aerobic exercise a day.

In addition to calorie disruption, Dr. Ian tells dieters to snack frequently, including specifics on timing. He also emphasizes what he calls “sliding nutrient density,” which means that you eat plant-based foods in the second part of your day.

In contrast, Dr. Travis focuses on food prescriptions so that your meals and snacks become your medicine: “The Doctor’s Diet: Dr. Travis Stork’s STAT Program to Help You Lose Weight & Restore Your Health”.

Although the “Doctor’s Diet” emphasizes health and weight loss equally, Dr. Travis does provide a four-week jump-start to accelerate weight loss, followed by diet to continue the weight loss and concluding with a maintenance plan. That four-week plan emphasizes healthy fats, moderately high protein and low-carb diet meals and snacks.

As for Dr. Ian’s emphasis on high-intensity exercise for 40 minutes, Dr. Travis prescribes only 30 minutes of an activity such as walking. In addition, Dr. Travis feels strongly about the dangers of sugar, telling dieters to surrender the sweet stuff while boosting their protein intake. While not eliminating carbohydrates, he says that those who engage in only minimal activity can benefit from low carb diets.

“We don’t know exactly why protein helps with weight loss. One reason is that it has an impact on the action of ghrelin, known as the hunger hormone, and leptin, the satiety hormone, which is why people who eat protein at each meal find they are fuller and less hungry after they eat than do people who skimp on protein,” he explains.
