A Nutritionist Says You Should Eat These Foods to Get Lara Croft–Level Abs

We've heard the saying, "Abs are made in the kitchen, not the gym." This means that no matter how many crunches you do, planks you hold, or weights you lift, it's crazy difficult to tone and define your abs without following a healthy diet. It's one of those pervasive fitness sayings, kind of like Gigi Hadid's famous one: "Eat clean to stay fit; have a burger to stay sane." Does anyone remember that one? Well, according to Amy Shapiro, MS, RD, CDN, founder and director of Real Nutrition NYC, there is definitely truth to the saying (the former one, at least). What many people might not know is that diet actually trumps fitness when it comes to building and maintaining the appearance of abdominal muscles. "You can build up your ab muscles as much as you want, but they will not be revealed unless the fat on top of them is reduced. This comes from cardio exercise and from a clean diet. I would say about an 80/20 split should be the focus: 80% what you eat and 20% what you do."
