Hello, my diet-conscious community! Are you looking for a perfect guide on fat on keto diet? You are at the right place. In this growing world, we all are getting modern, and our diet is trendy too. We think it’s stylish to eat junk food and to eat unhealthily. Today we are far away from a healthy diet. And this unhealthy diet leads to overweight which is the leading cause of chronic diseases, including diabetes, CVD, and many more diseases. Obesity is the main cause of every illness. So after eating unhealthy, and becoming obese, we people feel laziness, and because of overweight, we are unable to do work properly.

Overweight leads to laziness, sleeplessness, and discomfort. Because some people are foody and they love to eat spicy food. They prefer junk food instead of healthy. They become unable to follow a proper diet plan. So the keto diet is for those people who love to eat junk food. It is a low-carb, high-fat diet. In this, the diet forces the body to burn fat rather than carbohydrates. In this diet, protein is an inadequate amount. We are living in this growing world where nothing is impossible to do. One thing that is important to achieve your goal is ‘Consistency.’ You must have a passion for doing something.

Without any aim, no one can achieve a goal. Motivation is also important. If you are motivated, you can quickly achieve your goal. So as far as we talk about diet, no matter which type of diet it is, you can fast lose weight. Whether it is keto, or zero carbs, or any diet, you can easily lose weight. One most important thing is that you must be punctual. In diet, timings matter a lot. Like, take every meal on time, whether it is a substantial meal or a snack. Take every meal on time.

This will help you make good habits as well as your diet will benefit you more and more. Don’t lose hope; keep going, and you will get results. As hard work never pays off. It’s our mindset that we have to cut off fat from our diet while we are on a weight loss journey. But that’s not compulsory. We can eat fat too in our weight loss journey like in keto, we consume more fat, and we lose weight. In the keto diet, we have to consume more fat and fewer carbohydrates. So the question is that what happened if we do not eat enough fat on keto?

If you do not eat enough fat on a keto diet, you may face some medical issues like your immune system gets weaker, you may have dry rashes, hair fall, and many other disorders related to vitamin deficiencies. As we all know, fat consumption increases satiety (the feeling of fullness). And when the levels of satiety are high, we will eat and snack less. Snacking less will help us regulate food intake as well as appetite. So, if we take too much fat on keto, that fat will be stored in the body and will be used whenever the body needs it. 

This stored fat will helps in decreasing hunger and appetite. On the other hand, if we do not take enough fat on keto, our hunger and appetite will be increased. When appetite and hunger increase, we will automatically eat more to satisfy hunger, resulting in increased calorie intake. And consequently, our body will miss out on the nutritional benefits of healthy fats. If you are on a keto diet and your protein and carbohydrate intake are not in balance, then your body will not go on ketosis, and you will feel hungry all the time.

In the keto diet, managing protein and Carbohydrate intake is so important. Problems can arise if you do not eat enough fat on keto and your fat consumption is too low. For example, suppose you are not consuming fat according to your daily needs. In that case, you will be putting yourself in a large calorie deficit, and your body will adapt a way in which your energy expenditure will be decreased, and hunger and cravings will be reduced.

Consequently, this will cause you to lose weight, and at some point, it will become difficult for you to stay on a keto diet. To overcome these issues, you must keep your calorie deficit below 30%. This will not slow down your metabolism and will allow you to lose weight so that it will not decrease your calorie-burning capacity, and in the long term, it will impair your weight loss results.

If you want to eat enough fat to maintain a 30% calorie deficit and have trouble managing it. Here is a guide for you. You can add high-fat cheeses like cream cheese, cheddar cheese, etc.; etc. you can also add olive oil, butter, avocado oil, high-fat nuts, etc., to your meals to make your diet a 30% calorie deficit. When you know you need to fit some extra fat in your meals, you can add a couple of additional tablespoons of oil to soups, curries, dressings, sauces, etc.

Being a nutritionist, my suggestion to you people is that ‘Have a balanced diet’. Do not eat too less that you feel weak and you suffer from diseases. On the other hand, do not overeat as overeating leads to many chronic diseases. As I have already discussed, overweight leads to obesity, and obesity is the primary cause of many chronic diseases such as CVD (Cardiovascular disease), diabetes, hypertension, etc.

Try to eat in moderation. As in the keto diet, it is recommended to eat more fat and fewer carbohydrates. So do not over-consume fat and do not completely skip carbohydrates. If you are advised to consume a significant portion of fat in your meals, keep the calorie intake into consideration. Follow all the instruction as given by you Dietician or Nutritionist.

Exercise is a must if you want to have a toned body. To lose weight and keep it off, you must follow the rule of 80% nutrition and 20% diet. By following this rule, you may able to achieve your target soon. I will again say, ‘consistency is the key.’ Stay consistent and stay motivated. Motivation is the other most important thing in the weight loss journey. If you have started the diet and are not getting results in days or weeks, do not lose hope.

The body needs time to convert itself to any other diet. If we are consuming typical food for the year, and now we have started keto, it will take time to adjust. Nothing is possible if you want results in just the blink of an eye. Everything takes time. You need to have the patience to get results. Some people think diet not beneficial for them to lose weight as they are not getting results in days or weeks. You will get results; just be patient.
