20 Best Foods for the Keto Diet

Hopping on the ketogenic bandwagon? Here’s what you need to stock up on when you hit the supermarket.
20 Best Foods for the Keto Diet

There’s no denying that the ketogenic diet (keto for short) is the hottest new nutrition trend. And although it’s still controversial among dietitians, doctors, and other nutrition experts, there is some scientific research to back it up. In fact, a study published in the International Journal of Environmental Research and Public Health found that following a ketogenic diet can help control hunger levels and improve metabolic rate. If you want in on these weight-loss benefits, you need to make sure you are adhering to the diet’s key principles, which begins by stocking up on the right keto diet foods.

First and foremost, the keto diet is all about ratios: you want to make sure that carbohydrates make up 10 percent or less of your total caloric intake, with 15-25 percent from protein, and the remainder from healthy fat. Eating in this manner will help your body achieve ketosis, a metabolic process that occurs when the body resorts to burning fat for fuel, which only happens when glucose reserves are depleted. In basic terms, successfully following the keto diet means cutting out all sources of sugar and most carbohydrates and loading up on foods with high fat contents.

The key to sticking to keto guidelines is focusing on what you can eat, not what you’re cutting out. If you’re unsure about what’s safe to snack on, you are in luck. We have picked out our favorite, keto-friendly foods that will make eating a fat-centric diet easy and, dare we say it, enjoyable. Keep reading to learn what grocery store items you’ll need to successfully take the ketogenic plunge—as always, consult with your doctor before embarking on a new diet plan.
