Case in point: Jessica Simpson and Lauren Conrad are grapefruit fans. To prevent their thighs from developing a curd-like texture, Samantha Harris and Bachelorette star Ashley Hebert crack open the cottage cheese. And Jennifer Hudson, the poster girl for successful dieting, snacks on popcorn.
This shift is not lost on experts, who say there's not only a trend toward retro weight-loss methods, but new research to back up the slimming benefits of many of these foods.
What's old is new again
Interestingly, millennialswho were born in the 1980s and '90s and thus were not even alive when these foods dominated the diet world in the '60s and '70sare driving this movement back to the basics. "They yearn for authenticity and are distrustful of gimmicks," says Phil Lempert, food trend expert and founder of supermarketguru.com. So retro foodswhich are often minimally processed, easy to eat, and so low in calories and fat they're almost guaranteed to workappeal to them, Lempert adds.
And no matter your age, flashback foods can provide comfort. During uncertain timeslike nowwe revert to things that we remember from childhood and trust will work. "Nostalgic feelings often make people gravitate towards classic diet items," says Susan Albers, PsyD, a psychologist at the Cleveland Clinic Family Health Center and author of Eating Mindfully. "My clients tell me that they eat cabbage soup or low-fat cheese because those are things their mothers used to eat while dieting." (That may also be why we're reverting to all those gym-class classics like push-ups, jumping rope, and hula-hooping that are popping up everywhere from The Dr. Oz Show and Late Night with Jimmy Fallon to your fitness club's class schedule.)
This resurgence is also part of the natural cycle of food trends. For years, a steady stream of highly publicizedand celebrity-endorsedweight-loss books flooded the market. "But we're in a period of diet burnout," explains Brian Wansink, PhD, director of the Food and Brand Lab at Cornell University and author of Mindless Eating: Why We Eat More Than We Think. "Whenever a diet trend begins to die down because it doesn't deliver, there's renewed interest in these types of foods."
That's what is likely happening now, as waistline-watchers discover that gluten-free diets and exotic health foods like quinoa aren't automatically slimming. "I'm seeing people gain weight on gluten-free diets left and right," says Rachel Beller, RD, author of Eat to Lose, Eat to Win. "And things like quinoa and farro, while healthy, can be calorie bombs if you don't mind your portions."
