Because they help keep your blood sugar levels on an even keel. Maintaining moderate blood sugar levels can greatly reduce the risk of diabetes complications.
Research has shown that people with diabetes experience long-term improvements in blood sugar levels while eating a low carb diet.
That’s because people with diabetes are deficient in insulin or resistant to its effects. When they eat carbs, their blood sugar can rise to potentially dangerous levels unless they take medication.
Low carb diets help minimize these harmful effects if you have diabetes.
With type 2 diabetes, the ultimate goal is to keep your blood sugar levels within a moderate range. It’s carbs that influence your blood sugar level, not necessarily calories.
Eat a portion of sugar or refined carbs, even if it doesn’t take you past your daily calorie limit, and your blood sugar might spike.
Portion control is a very big part of carb counting because you may not always have a nutrition label available.
People who count carbohydrates will often memorize certain portions to make their food choices easier. This is sometimes called a consistent or controlled carbohydrate diet (CCHO). For example, a small apple or half a cup of cooked corn each has about 15 grams of carbs.
That said, counting calories can still be useful if your goal is to lose weight because it can help you stay under a daily calorie limit you set for yourself.
Yes! Low carb eating, including ketogenic diets, has health benefits that go way beyond helping manage your blood sugar.
Research shows that eating low carb:
Aim to eat a number of carbs per day that you can realistically maintain over the long term, and will help you meet your blood sugar goals and feel your best.
Practically speaking, when you have type 2 diabetes, choosing your daily carb limit also involves testing your blood sugar and making adjustments as needed based on your response, including how you feel.
A severely restricted carb intake of less than 10% of your daily calories appears to produce the most dramatic results and may reduce or even eliminate the need for insulin or diabetes medication. That’s a max of 50 grams of carbs per day on a 2,000-calorie diet.
But less severe carb restriction can help, too. Many people experience benefits from keeping their carb consumption under 26% of their daily calories.
On a 2,000-calorie diet, that’s a max of 130 grams per day.
The low carb options are endless (and delicious!). Here are a few swaps:
You don’t necessarily need to avoid certain foods completely to manage your blood sugar. Instead, you can reduce your portion size and combine refined-carb foods with foods that slow digestion, like fiber and protein.
For example, eating a smaller portion of white rice combined with lentil dahl or bean-packed chili will help prevent your blood sugar from spiking as much as it would from eating white rice alone.
Ketosis is a metabolic state in which your blood has a high concentration of ketones.
It’s typically caused by fasting or following a very low carb or keto diet. During ketosis, your body starts using fat instead of glucose (blood sugar) as its main fuel source.
But it can be hard to tell when you’re in ketosis.
Signs and symptoms that you’re in ketosis include:
To know for sure, you can also measure for increased ketones in your blood, breath, or urine with a special meter or strips.
Ketosis is a natural metabolic state that may have benefits for weight loss. It may also have therapeutic effects for people with epilepsy, type 2 diabetes, and other chronic conditions.
Ketosis is likely safe for most people, especially if they follow it with a doctor’s supervision.
However, it can have some negative effects, especially at the start. It’s also unclear how a ketogenic diet may affect the body in the long term.
Experts don’t know for sure. Staying in ketosis for a long time, like when you’re following a keto diet, is usually fine for healthy people. When used as a treatment for epilepsy, people have stayed on a keto diet for many years. More research is being done to determine the overall safety of the keto diet in the long term.
Some negative effects may include the risk of:
Talk with your doctor before making any drastic changes to your diet.
A type of medication called sodium-glucose cotransporter 2 (SGLT2) inhibitors for type 2 diabetes can increase the risk for diabetic ketoacidosis, a dangerous condition that increases blood acidity. Avoid keto diets if you’re taking this medication.
It may take you 2–4 days to enter ketosis, whether you’re fasting or on a keto or very low carb diet. However, some people may find it takes a week or longer to reach this state.
It may take longer if you consumed a high carb diet before starting a keto diet. This is because your body needs to deplete the glucose it’s stored before entering ketosis.
Other factors that affect how long it’ll take to get into ketosis include your physical activity level, age, metabolism, and intake of fat and protein.
Testing your body’s ketone levels is the best way to know whether you’re in ketosis, and you may also experience the typical signs and symptoms of being in this metabolic state.
