Keto diets have amassed a large following; however, keto diets also have their share of skeptics. Many people vow that Keto has changed their life, while some believe it has increased their weight.

So, who should you believe?

When opinions are so polarizing, trusting science is the best option.

Hence, let us help you understand the pros and cons of a keto diet as revealed by science and let you decide if a keto-based diet is the right choice for you.

Pros of Keto Diet


Helps Lose Weight Fast


A keto diet is significantly better, or might we dare say superior to a regular diet, in helping you lose weight. So, if you are trying to lose weight, you should not shun fat. Instead, it would be best to devise a plan with a high portion of fats and proteins.

A keto-based diet with high fats is more sustainable and healthier than a diet with high carbs and low fat.

If you are like us and care about numbers on the weight scale, here's a fun fact: on average, a keto-based diet helps you to lose 3kgs more than a regular diet!

Improves Blood Glucose Control

Insulin sensitivity is an issue that affects millions of people each day, putting them at risk of obesity and diabetes. Insulin sensitivity problems arise when a person consumes unhealthy amounts of sugar.

Many experts believe irregular blood glucose control could be one of the reasons why some people struggle to lose weight!

Keto-based diets have shown promising results for people with irregular insulin sensitivity since a keto diet relies on fat and reduces carbs intake leading to balanced blood glucose and regular insulin activity.

A study conducted by Westman and colleagues in 2008 revealed truly remarkable results where people with type 2 diabetes were reported to show a reduction in HbA1c levels by as much as 1.5%.

While a high-fat keto diet benefits people with blood glucose issues, it is even more beneficial for those trying to lose weight. A regulated blood glucose level helps to torch fat faster.

Enhances Heart Health

 Rapid weight increase, as well as weight loss, leads to a variety of health issues that can potentially harm the heart.

A keto-based diet – quite paradoxically – does the opposite. A high-fat diet has tremendous benefits for one’s heart. For example:

  • High-Blood Pressure: a ketogenic diet can improve cholesterol levels among people suffering from high blood pressure.
  • Cholesterol Levels: People who adopt a ketogenic diet experience an improvement in their cholesterol health. Most fitness enthusiasts and health-conscious participants reveal that after only six weeks of a keto diet, their low-density lipoproteins went down, and high-density lipoproteins increased, which is healthy.

Boosts Brain Function

 Fat-rich diets offer high amounts of Omega-3 in oily fish such as salmon and mackerel. Omega-3 increases the production of a fatty acid called DHA, which makes up 15 to 30% of our brain.

Therefore, your brain functions, including memory and retention, improve as you consume more healthy fats for a keto diet.

Detoxifies Body

 A keto diet combined with a detoxifying supplement like Beta-hydroxybutyrate (BHB)  helps eliminate toxins and harmful chemicals from the body.


Reduces Appetite


Do you find yourself craving food even after finishing an entire meal?

Or do you munch on snacks at frequent intervals?

If you experience regular hunger pangs impacting your overall health and weight, you could suffer from an irregular appetite.

Dieting is one way to regulate hunger, but it's not easy.

Hence, following a keto diet can be the easy solution you are looking for.

Once the body gets used to ketosis, our reliance on sugary foods and carbs reduces. Moreover, our body uses more fat than stored sugar to satisfy energy requirements.

Ultimately, you feel less hungry, your appetite becomes regulated, and you can stay away from food for as long as you want without munching on unhealthy snacks or junk food.

Cons of Keto Diet

 We have established that keto diets are effective and nothing short of a miracle diet for those struggling to lose weight. But so many great things come at a price. So, let's see what some cons of a keto diet are.

Keto Fever

 Anyone who has heard of the keto diet must have heard of the dreadful keto fever.

Keto fever is a significant drawback. While the fever only lasts a few days, it can be too much to handle for some people.

Fatigue, headache, dizziness, and irregular bowel movements in the first few days are some side effects that a person experiences when they are in an initial ketosis state.

An easy way out of a keto fever is to consider Keto Cleanse, which combines four natural herbs to reduce the side effects of a keto fever and help with an upset stomach.

Nutrients’ Deficiency


Cutting out carbs means cutting out whole grains, vegetables, and fruits. Consequently, your body can experience nutrient deficiency and an upset stomach.

Moreover, there are no long-term studies done on the effects of a keto-based diet. Therefore, you must practice caution when following a keto diet for longer.

Might Be Difficult To Stick To


A keto diet produces visible results much faster than any other diet. Despite its effectiveness, a keto diet is challenging to stick to.

Keto fever alone can deter a person and cause a relapse. Additionally, food choices become limited, pushing a person to switch to another diet. Luckily, there are a few food options like Keto Custard that satisfy cravings and help you stick to a keto diet.

Parting Thoughts


Every diet has pros and cons since dieting inherently requires cutting off food. Keto diets, however, have proven to be the most effective in losing weight.
