If you look into different strategies to lose weight, you’ll come across various diets and lifestyle changes that may transform your body into a fat-burning powerhouse.
Increasing the intensity and regularity of your workout program is one method for losing body fat and slimming your difficulty zones, but it is not the only one. You may also burn more fat by entering a metabolic state known as ketosis, the mechanism underlying several low-carb diets such as ketogenic and Atkins.
Understanding ketosis and how to attain it will help you get your body in shape.
But, before you try to attain ketosis, you should be aware of some of the process’s possible health dangers.
What Exactly Is Ketosis, and How Does It Influence Weight Loss?
Food is your body’s principal energy source, and three significant nutrients in meals provide this energy to your body. Carbohydrates, fat, and protein are the three types. Typically, your body will break down carbs from meals first, followed by fat and protein. Ketosis is a normal metabolic condition that happens when your body lacks carbohydrates (or glucose) for energy and instead burns fat.
When your carbohydrate intake is minimal, you enter ketosis. As your body breaks down fat, it generates an acid known as ketones or ketone bodies, the primary energy source for your body and brain.
Because ketosis changes your metabolism and depends on fat for energy, your body may burn fat more quickly. Translation? You may be able to attain your weight reduction target sooner than if you didn’t limit carbohydrates at all.
How Do You Successfully Achieve Ketosis?
It’s not simple to get your body into — and then stay in — ketosis. To get there and remain there, you’ll need to drastically limit your carbohydrate consumption, consuming no more than 20 to 50 grams (g) of carbs daily. A single medium pear, for example, has 26 g of carbs, and even items that aren’t often thought to be rich in carbs — such as nuts and nonstarchy vegetables — have a tiny amount of carbs and must be restricted or avoided on this diet.
You will need protein if you are on the keto diet, but you should restrict your consumption to roughly 20% of your total daily calories. (1) This is significant because when you take more protein than you need, your body turns the extra protein into carbohydrates through a process known as gluconeogenesis. This procedure causes your body to exit ketosis.
Another method for achieving ketosis is intermittent fasting. This does not imply fasting for days on end but somewhat intermittent fasting. You may either eat for eight hours and then fast for 16 hours, or you can follow a low-calorie diet for a few days (approximately 1,200 daily calories for women and 1,500 daily for men). When you eat less, your body burns more of its fat reserves for fuel.
According to research published in Frontiers in Physiology in October 2017, you may also speak to your doctor about adding supplements, such as exogenous ketones, to assist in placing and maintaining your body in ketosis.
What Are the Signs and Symptoms of a Ketosis Diet?
One technique to tell whether you’re in ketosis is to check your ketone level. This metabolic state generally manifests after three or four days of carbohydrate restriction or intermittent fasting. You do not need to see a doctor to determine your status. Purchase a ketone urine test from a local pharmacy shop, or use a blood sugar meter that can detect ketones.
A healthy blood ketone level is less than 0.6 millimoles per liter (mmol/L). (2) Any level more significant than this may suggest ketosis.
The following are the physical indications and symptoms of ketosis:
- Weight loss
- Appetite loss
- Increased energy may be reduced during the first few weeks of the diet.
- breath with a fruity aroma (halitosis)
- Diarrhea or constipation
Many of these symptoms are linked to what is known as the “keto flu.” According to experts, symptoms should go away after two weeks.
The Ketogenic Diet and Its Relationship with Ketosis
A keto diet, a very low-carb, high-fat diet, focuses on replacing carbs with healthy fats and purposefully puts the body into ketosis for weight reduction. Keep in mind that this diet isn’t just about eating fewer carbohydrates. It also emphasizes eating more whole foods and less processed meals.
This diet provides around 75% of your daily calories from fat, 20% from protein, and 5% from carbs. Following a standard keto diet food list, you may consume some things freely while limiting or altogether avoiding others!
On the keto diet, you may consume the following foods:
- Beef, lamb, pig, poultry, fish, and seafood are all examples of meat (preferably wild-caught)
- Eggs
- Cheese
- Healthy oils like olive oil, avocado oil, or coconut oil (but bear in mind that although coconut oil is allowed on the keto diet, it has been related to boosting LDL, or “bad,” cholesterol levels)
- Avocados
- Celery, asparagus, leafy greens, cucumber, and zucchini are nonstarchy vegetables.
- Seeds and nuts
The following foods should be avoided when on the keto diet:
- Grains such as rice, quinoa, white potatoes, pasta, bread, and pizza are examples of grains.
- Processed foods
- Artificial sweeteners
- Milk
- Fruits high in carbohydrates, such as bananas, pineapples, tangerines, and grapes
- Refined oils
One claimed advantage of the ketogenic diet is that it may help you lose more weight than other diets. A four-week high-protein, low-carbohydrate ketogenic diet helped decrease hunger, resulting in lower food consumption and higher weight reduction than a high-protein, medium-carbohydrate nonketogenic diet, according to one research of 17 obese males. (3)
Another study backs up this diet’s potential advantages. Preliminary research, for example, has linked the keto diet to reduce Alzheimer’s disease symptoms. (4) Previous research shows it may also help cure metabolic syndrome, manage Parkinson’s illness, regulate seizures in children with epilepsy, and, according to a tiny pilot trial’s findings, may even relieve polycystic ovarian syndrome symptoms (PCOS). (5, 6, and 7)
However, some studies have shown the keto diet’s possible health hazards. A low-carbohydrate, high-protein diet, for example, may be harmful owing to the possibility of raising bad cholesterol and triglycerides. (8) One research shows that a low-carbohydrate diet may cause insulin resistance, raising the risk of type 2 diabetes. (9)
It’s also worth noting that there have been no long-term studies on the ketogenic diet, nor has there been a study into what happens to the body if it’s always in a state of ketosis. However, since the body needs carbohydrates to operate correctly, fat-burning diets may result in nutritional shortages, and supplements and multivitamins are necessary because you’re cutting out whole food categories, advises Alyssa Rothschild, RDN, a private practice nutritionist in New York City.
Rothschild explains how adopting a ketogenic diet for a lengthy period may lead to osteopenia, a precursor to osteoporosis, a bone-loss condition.
“When the body is in ketosis, the blood pH drops, leading it to become acidic.” “To counteract this, the body removes calcium from the bones,” she explains. “Increased acidity in the body raises uric acid, which may contribute to kidney stone production.” As a result, persons with kidney impairment should avoid attempting to attain ketosis or the ketogenic diet owing to the stress that a very low-carb diet may have on the body. (10)
Women who are pregnant or breastfeeding, persons on specific diabetic medications and insulin, people with a low body mass index (BMI), children, people with gallstones, and people who have had their gallbladder removed should not attempt the ketogenic diet.
Is Ketosis Safe and Beneficial for Everyone?
The long-term implications of continuous ketosis have not been adequately studied. However, it seems safe for most individuals as a short-term weight-loss option.
Again, it’s vital to remember that this state might result in a high quantity of ketones in the circulation, which can cause the blood to become acidic, a severe medical condition.
Each person’s body reacts differently to ketosis. While some individuals can manufacture insulin during ketosis to reduce ketone synthesis and prevent dangerous levels, others cannot. When the blood gets acidic, ketosis becomes harmful. Before making any dietary changes, always consult with your healthcare professional.
What You Should Know About Diabetes and Ketosis (Type 1 and Type 2)
If you have type 2 diabetes and need to control your symptoms, following the ketogenic diet and reaching ketosis may be helpful. Limiting carbohydrate consumption is critical for people with type 2 diabetes since eating too many carbohydrates raises blood glucose levels, damaging blood vessels and leading to eye, kidney, and nerve issues.
Because you may achieve ketosis by limiting your carb consumption, this diet may naturally reduce your blood glucose levels. Furthermore, if you are overweight and have diabetes, consuming fewer carbohydrates may help you shed extra pounds, which is another strategy to get control of your blood glucose.
Many individuals with type 2 diabetes may go into ketosis because they still make insulin, which helps their bodies maintain a healthy amount of ketones in their blood. If you have type 2 diabetes and want to try ketosis or the ketogenic diet, talk to your doctor first to be sure it’s healthy. This meal plan may conflict with certain diabetic medications or be incorrect if you have diabetes complications such as renal damage.
In addition, attaining ketosis with type 1 diabetes may result in dangerously high levels of ketones in the bloodstream, leading to diabetic ketoacidosis. As a result, if you have type 1 diabetes, you should avoid sending your body into ketosis to avert this possibly fatal health catastrophe.
What Is the Difference Between Diabetic Ketoacidosis and Ketosis?
Although the terms seem similar, there is a distinction between ketosis and diabetic ketoacidosis. Whereas ketosis is a metabolic reaction, ketoacidosis is a potentially fatal diabetic consequence.
Diabetic ketoacidosis happens when ketone levels become too high due to a lack of insulin, poisoning the body. This illness may affect anybody with diabetes, although it is more frequent in those with type 1 diabetes because of their bodies’ inability to produce insulin. If their ketone levels grow, their bodies cannot generate insulin to reduce this production. This illness, if left untreated, might result in a diabetic coma or death.
A high blood glucose level, a high ketone level, dehydration, frequent urination, nausea, trouble breathing, and dry skin are all symptoms of diabetic ketoacidosis. If you have poorly controlled type 1 or type 2 diabetes, frequently test your blood glucose before and after meals, and monitor your ketone level if your blood sugar is more than 240 milligrams per deciliter (mg/dL).
A ketone level of 1.6 to 3.0 mmol/L is considered high and raises the risk of diabetic ketoacidosis. (11) Taking insulin and drinking water might lower your ketone level. If your level does not reduce or continues to climb, go to the hospital. A ketone level of more than 3.0 mmol/L is considered a medical emergency.
How Can You Help Prevent or Treat Ketosis?
Some individuals purposely enter ketosis to reduce weight by following a low-carb, high-fat diet. If you don’t want to enter ketosis, you may avoid or cure it by eating a well-balanced diet that contains carbohydrates, fat, and protein and not missing meals.
Maintain a carbohydrate consumption of 45 to 65 percent of total daily calories, a 20 to 35 percent fat intake, and a protein intake of 10 to 35 percent. (12) In other words, if you consume a 2,000-calorie diet, you should get no more than 1,300 calories from carbohydrates.
Bottom line: is ketosis safe for weight loss and overall health?
Weight reduction may be accelerated by shifting your metabolism and attaining ketosis, as well as other health advantages such as increased energy and decreased blood pressure. However, although ketosis is a desired nutritional condition for some individuals, it isn’t for everyone — and it’s not a wise long-term dietary plan owing to its restricted nature, which may lead to potentially hazardous nutritional shortages.
Before attempting to attain ketosis, consult your doctor to ensure your medication or other underlying health concerns will not put you at risk for further health difficulties or a health emergency.
