Kim Kardashian Had a ‘Last Supper’ Binge Before Starting a Diet. Here’s What Nutritionists Think

[brightcove:4639738292001 default]

But first, pizza.

That was Kim Kardashian’s plan before overhauling her diet, as she revealed on Sunday’s episode of Keeping Up With the Kardashians. On the show, Kim, Khloé, and Kim’s BFF Jonathan Cheban ventured around New York City for a couple of slices of pizza, followed by chocolate ice cream cones with rainbow sprinkles. It was all part of a final food indulgence before Kim would embark on a “lifestyle change” that she hopes will give her a “good body.” (As if she wasn't already #bodygoals!)

We don’t have the details on what exactly Kim’s lifestyle change will entail, but Cheban’s already betting she’ll fall off the wagon. “I’ve heard about ‘lifestyle changes’ before,” he said. “I’ll see her at Cipriani—she cannot resist that pasta.”

“I’m really going to be dedicated and committed,” Kim fired back. “You’ll see.”

Sorry Kim, we've got disappointing news for you: Feasting on your favorite foods before banning them from your diet sets you up for failure, as Cheban predicted. “If you’re starting a diet on this notion that you have to restrict foods you love, that means the diet is unsustainable and you’re going to fail,” says Julie Upton, RD, co-founder of Appetite for Health.

That's because a binge-then-restrict plan requires a heck of a lot of willpower, especially if you’re denying yourself foods you really crave, explains Claudia T. Felty, PhD, RD. “Over time, you’re going to be around those foods and you’re going to be tempted by them,” she says. “When you set them up as foods you binge on now and then never eat again, that binge mentality comes back.”

Plenty of dieters believe that a Kim-style “last supper” will jumpstart lasting eating-habit changes, Upton says, but what it really does is “jumpstart the desire to get off the diet and [eat] the foods they’ve been restricting!”

When you decide a food you love is entirely off limits, you're more likely to fixate on that no-no. “We want what we can’t have,” Felty says, and this longing can actually trigger more intense cravings. Plus, telling yourself you simply "can't" have certain foods turns eating into a moral issue. “It sets up this 'good food' versus 'bad food' mentality that, for a lot of people, feeds an unhealthy relationship with foods that they love,” Upton adds.

A smarter approach is identifying an eating plan that meshes with your lifestyle and food preferences and then taking small, sustainable steps to keep at it. “For someone who loves pasta or bread, a ketogenic diet is never going to work, because they’re going to constantly crave those foods,” Upton says. Instead, following a Mediterranean-style diet that allows for some grains can lead to slow and steady weight loss, she says.

Felty and Upton both recommend the 80-20 rule. For 80% of the time, stick to a healthy eating plan; 20% of the time, enjoy the treats you love that don’t necessarily fit that plan on a daily basis, like pizza and ice cream. As long as you're also exercising regularly and you consume them in reasonable quantities, incorporating those treat foods 20% of the time won't derail your weight loss goals, Felty says.

Here’s How the ‘Biggest Loser’ Contestants Have Kept the Weight Off

[brightcove:5599232558001 default]

Your diet may help you lose weight, but exercise appears to be the key to keeping it off.

A new study, published in the journal Obesity, tracked 14 former Biggest Loser contestants to determine how some of them kept weight off after the show. Physical activity, the researchers determined, was the clear answer — even though diet, not exercise, was shown to help the contestants lose weight in the first place.

Half of the study participants maintained their weight loss after the Biggest Loser ended, while the other half gained the pounds back. Over six years of follow-up, the maintainers tended to be far more active than the other group, increasing physical activity by up to 160% since they started losing weight. Those who regained weight, by contrast, only increased physical activity by 25% to 34%. Overall, maintainers completed an average of 80 minutes of moderate exercise or 35 minutes of vigorous exercise each day — well exceeding the national physical activity guidelines of 150 minutes of moderate exercise or 75 minutes of vigorous exercise per week. 

The findings tie into another study published by the same researchers last year. Back then, they found that contestants' metabolisms slowed drastically after their dramatic weight losses, significantly cutting into the number of calories they were able to burn each day. As a result, many contestants saw the pounds creep back on, sometimes even exceeding their pre-show weights. 

Exercise, the new study suggests, may counteract that effect, helping people burn enough calories to stay thin. But the time commitment of a robust fitness regimen can make weight maintenance an uphill battle, according to former Biggest Loser contestant and study author Dr. Jennifer Kerns, who is now an obesity specialist at Washington's Veterans Affairs Medical Center.

“The amount of time and dedication it takes to manage one’s food intake and prioritize exercise every day can be an untenable burden for many people," Kerns told the New York Times. "It's totally unfair to judge those who can't do it."
