Ketogenic Diet – The Benefits And Risks You Need To Be Aware Of

The concept of a high-fat diet may seem counterintuitive to those trying to lose weight, but research suggests that the Ketogenic Diet, also known as the “fat-busting diet,” can be an effective way to shed pounds and improve overall health. This diet, which was first introduced in 1924 by Dr. Russell Wilder at the Mayo Clinic, involves consuming high amounts of fat, moderate amounts of protein, and low amounts of carbohydrates.

According to HealthifyMe senior nutritionist Neha Jain, the Ketogenic Diet works by changing the way the body uses energy. “This diet works extremely well for those people who have hit a weight loss plateau and are keen to change their metabolic system. As the body ends up using fat reserves for energy, it helps you get leaner faster,” she explains. The diet recommends a meal plan that includes high fat (up to 70-80%), moderate protein (15-30%), and low carbohydrate (5-10%) intake, which forces the body to use fat instead of glucose for energy.

How the Ketogenic Diet Works

The Ketogenic Diet leads to a high level of ketones, which are acids made when the liver breaks down fat for energy, in the bloodstream. Ketones are the preferred source of fuel for the body, particularly the brain, and their presence can change the body’s metabolism, veering it away from glucose burning towards fat burning. However, it’s essential to note that the diet involves consuming high amounts of “good” fat, such as nuts, seeds, avocados, olives, vegetable oils, and fish, rather than saturated fats.

The Benefits of a Ketogenic Diet

1. Accelerated Weight Loss

Research has shown that low-carb diets, such as the Ketogenic Diet, can lead to faster weight loss without feeling hungry or counting calories rigorously. A 2014 study conducted by the National Institutes of Health found that low-carb diets were more effective for weight loss and cardiovascular risk factor reduction than low-fat diets.

2. Improved Cognitive Function

A report published in The Journal of Physiology linked a high-sugar diet coupled with a deficiency of omega-3 fatty acids to lower cognitive scores and insulin resistance. The Ketogenic Diet leads to positive alterations in brain energy metabolism because of the partial replacement of glucose as the primary fuel.

3. Reduced Risk of Metabolic Syndrome and Heart Disease

Research has shown that a ketogenic diet can stave off metabolic syndrome. A 2012 study published in The American Journal of Epidemiology revealed that low-carb diets are more effective at reducing certain metabolic and heart disease risk factors than low-fat diets are.

4. Potential Cancer Treatment

Research has shown that regulating the body’s metabolic functions may be the key to treating cancer. Removing carbohydrates from your diet, the keto way, can deplete cancer cells of their energy supply and stop them from spreading.

5. Lower Risk of Type 2 Diabetes

Cutting carbs helps people with Type 2 diabetes because carbohydrates turn to blood sugar and can, in large quantities, cause blood sugar spikes. The Ketogenic Diet, high in fat and low in carbs, can potentially change the way the body stores and uses energy, easing diabetes symptoms.

6. Reduced Food Cravings

One of the most talked-about benefits of the keto diet is the fact that eating fewer carbs and more healthy fats and proteins satisfies all your cravings – as ghrelin, the “hungry hormone,” is switched off. The diet switches on the body’s satiety hormones and lets you stay longer without needing to snack.

The Risks of a Ketogenic Diet

1. Fatigue and Irritability

Ketogenic diets may lead to carb flu, a side effect that translates into fatigue and irritability. A 2007 study published in The Journal of the American Dietetic Association revealed that blood ketone levels are directly related to feelings of fatigue and higher perceived effort during exercise in overweight adults on low-carb diets.

2. Brain Fog

Staying on a keto diet for long leads to a metabolic shift in the body. This may make you sluggish and moody, and may result in your not being able to focus and think clearly. This is more so if you reduced your carbs drastically, so avoid that at all costs.

3. Changes in Lipid Profile

If you include large amounts of saturated fats in your diet, it may affect your blood lipid profile adversely. Cholesterol levels tend to increase if you opt for unhealthy fats; avoid this pitfall by choosing healthy fats.

4. Micronutrient Deficiencies

A low-carb diet is usually lacking in micronutrients, including thiamin, folate, calcium, iron, potassium, and magnesium – this is because your intake of carbohydrates is limited. Sidestep this problem by taking a high-quality multivitamin.

5. Ketoacidosis

If the level of ketones in your blood gets out of control, it may lead to ketoacidosis. The pH level of the blood drops, creating a high-acidic environment, which can pose a severe health risk for diabetics.

6. Muscle Loss

Like every other reduced-calorie diet, a ketogenic diet is catabolic, meaning it can lead to loss of muscle. This happens as you consume less energy and your body relies on other tissue – such as protein – to serve as an energy source. If accompanied by intense exercise, it can cause further breakdown of muscle.

In conclusion, while the Ketogenic Diet may be an effective way to lose weight and improve overall health, it’s essential to be aware of the potential risks and to consult with a healthcare professional or registered dietitian before starting the diet. As Neha Jain cautions, “Factors like age, gender, level of activity, body weight, and genetic disposition matter, and it’s best to consult an expert for a balanced diet plan.” For more information on the Ketogenic Diet, visit Here.
