- Justin Gelband has trained Victoria's Secret models including Candice Swanepoel, Karlie Kloss, and Martha Hunt.
- Business Insider spoke with him following a trip to London.
- According to Gelband, "85% of what you do is what you eat."
- Gelband is a fan of the paleo or "caveman" diet.
- He said the one regime that once made his models actually gain weight in the lead up to a show was a juice cleanse.
Justin Gelband, also known as "the model whisperer," has trained a number of Victoria's Secret models such as Candice Swanepoel and Karlie Kloss, as well as some rising stars like Alexina Graham.
In the lead up to this year's VS Fashion Show, he flew to Shanghai for last minute training sessions with the angels.
When we caught up with Gelband in London this summer he told Business Insider that while exercise is central to his brand, body maintenance is not just about working out. "85% of what you do is what you eat," he said.
Many nutrition experts have stressed the importance of healthy eating habits as a faster way to achieve your fitness goal than simply focusing on exercise.
"In order to lose a kilo of fat you would probably have to run two marathons," Michael Mosley, author of the "5:2 diet" and the "Clever Guts Diet," told Business Insider in a video interview. "In many ways it is obviously much easier simply to reduce the amount of calories you eat rather than trying to run them off because you have to do so much exercise to burn calories."
There is no one-size-fits-all diet, Gelband admits, though he's a fan of the paleo diet, also known as the "caveman diet." The regime is mainly based on foods that were around in the stone-age, such as fruit, vegetables, roots, and nuts.
On the other hand, the Victoria's Secret model trainer is cautious about juice-only diets, especially if people are using juicing as a method to shed pounds.
"At Fashion Week some models went on a juice diet and didn't tell me," Gelband said. "Not one lost weight, some actually gained weight. That got me in big trouble."
In a typical juice cleanse or diet, you dramatically reduce your calorie intake, which can lead the body to hold onto to extra calories.
Registered dietitian Ilyse Schapiro told Eat This: "Once you stop eating enough food to meet your basic energy requirements, your metabolism will slow. For most people, that threshold of calorie intake is around 1,200 calories per day.
She explained that at this point your body goes into conservation mode — or starvation mode — because it doesn’t know when its next meal is going to be. Going too low for too long, like more than a couple of days, can have the opposite effect, Schapirophe told the website. In this mode your body can start clinging on to every calorie it can get.
For this year's show Gelband helped prep the bodies of Swanepoel, Sara Sampaio, Grace Elizabeth, Megan Williams, Sanne Vloet, and Alexina Graham.
Here he is training Victoria's Secret newbie Graham, who made her debut in this year's show on Monday November 20.
"There's a time and place for juice fasting — just not for weight loss," Gelband said. "If you're on a yoga retreat in Bali, you're meditating and doing yoga and you want to drink juices because you don't want any heavy foods in your body, that's fine," he added.
Gelband said he has "a gift" for whipping Victoria's Secret models into shape, but that he "makes them eat. "Food is key to energy," he said. "They're not bean poles."
