Ketogenic diet: what are low-carb keto fruits?

The ketogenic diet is based on eating a diet that is high in fat, moderate in protein, and very low in carbohydrates. In recent years, we are talking about it more and more because its health benefits are not negligible. According to studies, the keto diet contributes to the treatment of certain diseases such as epilepsy, diabetes, or cancer.

Do not forget about weight loss without cravings! The principle of the diet is to enter a state of ketosis – the moment when the body uses fat as its main source of energy (the stores of sugar or rather glucose become insufficient). This explains why carbohydrate intake is limited to the strict minimum.

As a rule, fruits are among the foods that we deprive ourselves of first. But not all fruits have high sugar content, so there is no point in removing all of them from your diet. In this article, we reveal the keto fruits to consume to stay under the carb limit.

The Keto Diet and Carbohydrate Levels Needed to Stay in Ketosis

To enter a state of ketosis, the recommended daily macronutrient breakdown is 70-75% fat, 20-25% protein, and 5-10% carbohydrate. For example, for an 18,000 calorie diet, one should consume 140 to 150 grams of fat, 90 to 113 grams of protein, and 23 to 45 grams of carbohydrates per day.

The carbohydrate levels needed to stay in ketosis vary from person to person. It is believed that for the majority of the population a daily intake of 50 grams or less is sufficient. For athletes, the limit can be between 80 and 100 grams. When it comes to diabetics, it is necessary to aim for a limit of 20 to 30 grams per day.

But we talk more and more often about total carbohydrates and net carbs. It is explained for newcomers on the ketogenic diet. The total carbohydrates the total number of carbohydrates consumed in a day. As to net carbs, these represent the total number of carbohydrates in a given food, minus the grams of fiber and sugar alcohols (the latter are not digested by the body). So, if you are on the keto diet for medical reasons, it is necessary to limit your total carbohydrate count to 20 grams total per day. On the other hand, if it’s weight loss that is your goal, prefer to stay at less than 20 grams of net carbs per day.

Raspberries also contain several phytochemicals, including anthocyanins and quercetin.

A whole avocado provides 322 calories, 17.1 grams of carbohydrate, 13.5 grams of dietary fiber (or 3.6 grams of net carbs).

Avocado is an excellent source of vitamins C, E, K, and B6; folic acid, pantothenic acid, and potassium. The fruit is also prized for its content of riboflavin, niacin, magnesium, phosphorus, copper, and manganese. Vitamin B6 helps the body produce a variety of hormones such as serotonin, norepinephrine, and melatonin. Copper plays a role in the formation of red blood cells, the maintenance of nerve cells and the immune system. The trace element also contributes to the production of collagen and normal energy metabolism.

This ketogenic fruit also contains lutein, an antioxidant that helps keep eyes healthy, and β-sitosterol that studies have linked to lowering blood cholesterol.
