The authors noted the lack of increased hunger despite extreme restrictions of both diets, which they theorized were due to changes in appetite hormones such as ghrelin and leptin, ketone bodies, and increased fat and protein intakes.

The authors suggested further studies exploring a threshold of ketone levels needed to suppress appetite; in other words, can a higher amount of carbohydrate be eaten with a milder level of ketosis that might still produce a satiating effect? This could allow inclusion of healthful higher carbohydrate foods like whole grains, legumes, and fruit.

Their levels of ghrelin did not increase while they were in ketosis, which contributed to a decreased appetite. However during the 2-week period when they came off the diet, ghrelin levels and urges to eat significantly increased.

Eighty-eight percent of the participants were compliant with the entire regimen. References Paoli A, Rubini A, Volek JS, Grimaldi KA. Beyond weight loss: a review of the therapeutic uses of very-low-carbohydrate ketogenic diets. Eur J Clin Nutr.

That said, although there are several theories as to why keto diets promote weight loss, they have not been consistently demonstrated in the research. In fact, there have been few long-term studies on the keto diet.

Although, a study did suggest that those on a very low-carb diet achieved a greater weight loss over a longer period than those following a low-fat diet. Keto diets appear to lead to weight loss and may improve insulin sensitivity , in those with diabetes.

When compared to a low-fat diet, a keto diet appears to achieve greater reduction in body weight. Weight loss at the start of the diet may be rapid, in some cases as much as 10 pounds 4.

This initial loss is typically due to the diuretic effect of the diet water is lost as stored muscle glucose is used up and is subsequently followed by fat loss. As ketosis continues, you may experience less hunger and because ketosis is a calorie-consuming process there is an increased calorie demand to convert fat and protein to ketones you may experience further fat loss.

How long weight loss is maintained, however, is dependent on your ability to adapt your dietary habits once you start to introduce a more balanced and healthy approach to eating. From an evolutionary perspective, ketosis is a normal adaptive response which enabled humans to withstand periods of famine.

Today, this natural mechanism is being exploited by low-carb weight loss regimes. Following such a diet means you replace carbs with foods rich in fat and protein, and if followed over an extended period of time, this may have unfavourable consequences for some people.

Eating high-fat foods is likely to increase your saturated fat intake, which UK government guidelines recommend we limit to 30g for men and 20g for women.

High levels of dietary protein are thought to be an issue if you have an underlying kidney condition — although most keto diets supply moderate rather than high levels of protein. The symptoms associated with ketosis are often temporary and relate predominantly to dehydration, because of the water loss experienced in the early stages of the diet.

These may include headache, dry mouth, bad breath, fatigue and nausea. Finally, long-term compliance can prove challenging — food choices are limited which can severely restrict eating out with family and friends. Diabetics and anyone with a blood sugar management issue should discuss the potential implications with their GP and healthcare team before embarking on such a regime.

Similarly, anyone who meets one or more of these criteria:. Please note: if you're considering attempting any form of diet, please consult your GP first to ensure you can do so without risk to health.

The ketogenic diet—called the "keto" or just " keto "—is one of many weight-loss eating patterns. Though this way of eating may help you lose weight, some keto diet side effects and complications can include diarrhea, mineral deficiencies, or reduced athletic performance.

A person can experience these effects as the body achieves a state of ketosis by decreasing carbohydrate intake to 50 grams or less daily. In ketosis, the body has to burn fat rather than sugar for energy.

Here's what you need to know. Drastic changes in eating patterns can lead to side effects beyond weight changes. For people following the keto diet, doing it incorrectly or for too long may increase the risk of side effects like kidney stones or nutrient deficiencies.

This type of diet can cause individuals to have water loss before fat loss. As a result, one of the possible early side effects of ketogenic diets is dehydration. Dehydration occurs when your body loses too much fluid. When you're dehydrated, you lose more fluid than you're taking in.

Some symptoms of dehydration can include:. Common side effects of a keto diet are gastrointestinal GI problems like constipation, diarrhea, nausea, or vomiting. Of those problems, diarrhea happens more frequently—potentially due to the body having difficulty absorbing the high-fat content of foods part of the diet.

The keto diet could lead to kidney stones, mineral-formed substances in your kidneys. One review found that kidney stones are more likely to occur in people without kidney disease following keto because of the focus on animal-based and high-fat foods.

For those with kidney disease, keto can lead to further long-term kidney damage, and worsen metabolic acidosis. The review also indicated that ketoacidosis may be responsible for kidney stone formation due to decreased citrate and pH levels and increased calcium levels in the urine.

Ketoacidosis occurs when too many ketones, acids produced as fat-burn byproducts, build up in the blood.

The ketones make the blood acidic and can spill over into your urine. Ketosis can trigger ketoacidosis in individuals with type 1 diabetes due to having a lack of insulin to use glucose.

The condition can be fatal if left untreated, so seek immediate medical attention for signs of ketoacidosis. Athletes may consider the ketogenic diet helpful for weight loss and improved sports performance. However, researchers found that participants performed worse on high-intensity cycling and running tasks after four days on a ketogenic diet than those who'd spent four days on a high-carb diet.

For some people, going on the keto diet can lead to the keto flu. It consists of the following symptoms:. You may minimize the effects of keto flu by drinking plenty of water and increasing electrolyte intake.

Other helpful actions include slowly decreasing your carb intake and easing your way into the diet. Many fruits and vegetables may be limited or eliminated to keep carb intake low on the keto diet.

Doing so may lead to a lower intake of important nutrients such as:. Specifically, a person using the keto diet may also miss out on folate and thiamin as well as vitamins A, B6, B12, C, E, and K. These and other vitamins are essential for body functions and development related to bones, gums, metabolism , red blood cells, and more.

Due to the keto diet's level of restriction for eating, people may regain any lost weight when they return to their initial eating patterns. This is in part because it's difficult to follow long-term and sustain. Recommendations for the length of time to stay on the diet range from two to three weeks up to 12 months.

If the keto diet is something you're interested in, talk with a dietitian for guidance. While the keto diet has many less desirable side effects, you could experience beneficial side effects for your physical and mental health.

The keto diet can be helpful for appetite regulation by affecting ghrelin. Ghrelin is the hormone that tells you you're hungry. There is an increase in ghrelin secretion when a person loses weight from dieting. However, this hormonal response becomes decreased during ketosis.

I can't stress enough the importance of planning for a keto diet. I ate a lot of bacon, cheese, eggs and meat—mostly steak and chicken. For a person whose eating philosophy is typically more plant-based and whole-food-focused , eating processed pork products every morning was definitely a big change.

Keeping your carb count near 20 g reduces your calorie consumption too. Carb-focused foods can contribute a large share of calories mainly because we eat a lot of them. If you cut way down on carbs, you dramatically reduce calorie intake.

You would think with all that fat and protein that it would be easy to overdo it on calories. But some days, I struggled to get over 1, calories. Despite my goal of 1, calories, I fell short almost every day.

That's enough of a calorie deficit to produce weight loss, even without the low-carb count. The "keto flu" is a term you'll see on keto blogs and forums. It was a real event for me, but not everyone will experience it. As your body starts to rely on ketones from the fat you're burning instead of glucose from carbohydrates, you may experience fatigue, mental fogginess and even irritability.

My "keto flu" only lasted a day, and I never experienced the symptoms again once I passed it. Featured Recipe: Soy Sauce Eggs. While I set out to lose 10 pounds, I quickly surpassed my goal. I lost 10 pounds within three weeks and hit 15 pounds two days before the wedding.

It's important to remember that when you are on a low-carb diet of any type, you will lose several pounds in the first few days. That's because your body is dropping water weight. When I returned to typical eating over the wedding weekend, I gained 4 pounds because when I started eating carbs again the water weight returned.

While on the keto diet, I had a lot of energy, and I didn't experience the typical mid-afternoon energy slumps. With that said, gym time was a bit of a challenge. Without carbs, your body has to burn fat for energy, which some days will leave you feeling drained during a workout because your body has to work harder to release the fat so it can be used for energy.

That's OK. Stick with it, and try again tomorrow. Eating at a restaurant and keeping your keto status is almost impossible—and after asking the server to hold the onions from your chicken fajitas for the third time, you'll never want to go into a restaurant again.

Luckily, I consider myself an adventurous cook and love trying new recipes. Of course, with a keto plan, your ingredient list is dramatically shortened. I scoured blogs, Instagram, Pinterest and other sources for reliable recipes, then put my thinking cap on and came up with several dishes I really enjoyed.

Write the recipes down, use a meal-tracking app like MyFitnessPal to record the ingredients and determine if a recipe works for you. It takes a bit more work than an average meal plan, but it's worth it. You can't eat sugar on the keto diet, and most of the no-carb sugar substitutes don't work for me.

This isn't to say that my cravings simply went away. In the first few days, cravings for a peanut butter cup, soda or even just a banana were strong. Here's when having an accountability buddy really helps. When you go back to typical eating, you might find, as I did, that many foods you ate regularly are now just too sweet to finish.

If nothing else, my monthlong experiment helped me eat less sugar and refined carbs. It's important that you check with your health care practitioner before trying this diet, as the keto diet is not for everyone. Certainly, there are plenty of people who should not try this diet, including if you're pregnant or breastfeeding, and those with blood sugar issues, heart disease and liver disease, among other conditions.

With that said, if you're in good health and are looking for a weight loss jump-start, the keto diet might be the opportunity you've been looking for. I just hope you really like bacon. Read More: 7 Things I Wish I Knew Before Starting the Keto Diet. Use limited data to select advertising.

Ketogenic diets consist of foods that fill a person up and may reduce hunger-stimulating hormones. For these reasons, following a keto diet may reduce appetite and promote weight loss.

In a meta-analysis of 13 different randomized controlled trials, researchers found that people following ketogenic diets lost 2 pounds lbs more than those following low fat diets over 1 year.

One study found that the ketogenic diet may be a safe and suitable complementary treatment to use alongside chemotherapy and radiation therapy in people with certain cancers.

This is because it would cause more oxidative stress in cancer cells than in normal cells, causing them to die. A more recent study from suggests that because the ketogenic diet reduces blood sugar, it could also lower the risk of insulin complications.

Insulin is a hormone that controls blood sugar that may have links to some cancers. Although some research indicates that the ketogenic diet may have some benefit in cancer treatment, studies in this area are limited. Researchers need to carry out more studies to fully understand the potential benefits of the ketogenic diet in cancer prevention and treatment.
