Starchy vegetables contain more digestible carbohydrates than fiber and should be limited when you're on the ketogenic diet. These include corn, potatoes, sweet potatoes and beets. Limit high-sugar fruits too, which spike your blood sugar more quickly than berries and have more carbohydrates.
However, corn and root vegetables like potatoes, yams, and beets have a high starch content and are best avoided. Choose non-starchy vegetables like broccoli, squash, bell peppers, and asparagus to get your fill of fiber and other nutrients while still moderating your intake of carbs.
"Carrots can be eaten on a keto diet, but in smaller quantities because they're higher in sugar than leafy greens," says Abby Langer, R.D., author of Good Food, Bad Diet. Since sugar counts as carbs on the keto diet, your average 1 cup of carrots has 12 grams of carbs, 4 of which are fiber.
The emphasis on non-starchy vegetables on a well-formulated ketogenic diet is for mineral balance as well as a vehicle for both salt and fat. If one finds that vegetables are not regularly part of a daily routine, a multivitamin would help, but there would still be concerns about adequate potassium and magnesium.
Cucumber is another popular salad vegetable. It contains many essential nutrients, including vitamin K. Cucumber is also suitable for the keto diet, as its carb content is just 3.63 g per 100 g. To make the carb content lower, a person can peel the cucumber before eating it.
Refined High-Carb Foods
Perhaps one of the most common things that kicks you out of ketosis is also the most tempting: foods high in refined carbs like bread, pasta, and rice. Most people find that they need to consume fewer than 20 grams of carbs per day to maintain ketosis.
SUMMARY. Tomatoes, unlike most fruits, are low-sugar, low-carb, and have almost no fat which makes them great for keto dieters.
Keto fruits by definition are low in carbohydrates. You still need to exercise portion control with most keto-friendly fruits to be within the limits of a keto diet. Keto-friendly fruits include avocados, watermelon, strawberries, lemons, tomatoes, raspberries, peaches, cantaloupe, star fruit, and blackberries.
Cloud bread
Cloud bread, or oopsie bread, is very popular with low-carb and keto dieters. Cloud bread is a protein-rich alternative to regular bread and makes an excellent sandwich base or English muffin replacement.
THE WORST: Refined or processed carbohydrates. These are carbohydrates like white bread, white sugar, white flour pasta, and white rice that have been stripped of their blood-sugar-buffering fiber, as well as vitamins, minerals, and antioxidants, things both your body and hair are big fans of.
By decreasing carbohydrate consumption such as bread, the body burns stored energy as glycogen (which is the image of stored carbohydrates in the liver and muscles), which leads to water loss and weight loss.
Foods you can eat on the keto diet include fish and seafood, meat and poultry, non-starchy vegetables like bell peppers, broccoli, and zucchini, avocados, berries, nuts and seeds, eggs, high-fat dairy products, olive oil and other oils, and high-cocoa chocolate.
If you follow the ketogenic diet, it's essential that you know how to calculate net carbs: the carbohydrates that your body actually processes and uses for energy. Fiber and certain sugar alcohols don't count toward your total carbs on keto, so you can subtract them from your daily total—with some important exceptions.
Dairy milk is also high in carbs, so it's not keto-friendly. Skip (or at the very least, limit) diet drinks, too, says Jill Gulotta, a registered dietitian nutritionist in private practice in White Plains, New York.
Is Greek Yogurt Keto? Yes! Especially for those of us who struggle to meet protein needs, Greek yogurt is an excellent choice on the keto diet. A 3/4 cup serving of full fat Greek yogurt has 5g of carbs, 9g of fat, and 15g of protein, making it my favorite choice for the keto diet.
Grapes are not considered keto-friendly as they are relatively high in carbs. One cup of grapes contains about 26 grams of net carbs, which is more than the daily carb limit for many people following a ketogenic diet.
For the human body to turn fat into ketones, it needs plenty of water, as this process doesn't just occur in the digestive tract—the body's stores of fat are also converted to ketones, providing an extra energy boost between meals. Water is an essential tool for getting the most out of your keto diet.
What Happens When You Eat Too Many Carbs While on Keto? It's common to reach for the carbs when you decide it's time for your keto cheat day. However, that isn't always the best option. If you eat more than 50 grams of carbs in a day, you'll throw your body out of ketosis.
