All The Foods You Can’t Eat Once You Start the Keto Diet

The keto diet is a very low-carb, high-fat, moderate-protein diet. When you start it, you cut out many foods that you used to eat, and your body takes some time to adjust to this new way. However, since the diet is very strict, there are a lot of foods that you can no longer eat. Here’s a rundown of what to avoid.

You’ve always been told fruit is healthy. And while that still holds true, it isn’t healthy for someone on a keto diet. Fruit is very high in sugar, and the keto diet is very strict about sugar intake. Dried fruits and fruit smoothies should also be avoided. But if you’re a fruit lover and need to splurge once in a while, aim for fruits lower in sugar, such as blueberries and blackberries. But don’t indulge too often.


Pasta is definitely a food you’ll want to avoid. It’s loaded with carbs, so gone are the days of macaroni and cheese and penne alla vodka. Even whole wheat pasta is still extremely high in carbs, so for keto purposes, it’s no better than refined pasta. Carbs are essentially refined or unrefined sugars, and the keto diet leaves very little room for either one.


Bread is another food high in carbs. It might be delicious, but it’s a no-go if you’re on a keto diet. In terms of refined sugars, white bread is the worst of the worst — even more so than pasta. Your body needs to adjust to finding energy through other outlets, so indulging in a piece of white bread every once in a while will only confuse it. Stick to the low-carb rules and avoid the bread.


Alcohol in general tends to be high in carbs, but beer is definitely a drink you’ll want to avoid. Even light beers still pack more carbs than the keto diet allows. Depending on the type of alcohol, you can still drink, but definitely skip over the beer aisle if you’re going keto.


The keto diet also leaves no room for starchy veggies, so sadly, potatoes are out of the question. They’re just about the starchiest vegetable you can find. Mashed, baked, or fried, they’re off the table. Try to incorporate more green vegetables into your diet; those are keto-approved.


Juice tends to have a ton of sugar in it. And even if it has zero added sugar, it likely still has sugar from fruit. It’s one of those drinks that tastes delicious but definitely isn’t good for anyone on a keto diet (sort of like the beer). Unsweetened tea is a good alternative to juice, since it has antioxidants and is sugar free.


Rice is another starchy food you’ll want to avoid. This means no sushi, either, since brown rice is no better than white rice for those on a keto diet. Try subbing a quarter-cup of quinoa in for rice. It has a similar texture but a much lower net-carb amount.


Beans are good for your heart, but you’ll have to ditch them if you go keto. They have a high carb content, and other legumes fall into the “avoid at all costs” category, too. Lentils, chickpeas, lima beans, and pretty much anything else with “beans” in the name should be avoided.
