Low-Carb Diet Vs. Vegan Diet: Which Is The Ultimate Weight-Loss Diet

We all want the best. This usually applies for the best job, the best house, and indeed the best health. Our health largely depends on what we eat. Since now more than ever people are eating healthier food and following many diets, people are in search of the best options. The best thing about all of this is that there are too many diets to choose from. This means you won’t be able to find only one diet that fits you. The fact that there are remarkably many diets also means you have to go through various diets in order to find one that works for you. Low-carb diet vs vegan diet, which is the best?


Expert Opinion

During the American Heart Association’s Scientific Sessions annual meeting, different experts tried to define the best diet. The experts agreed on these few characteristics of a good or the best diet. According to them, a diet is only better than another one if it is more sustainable in the long term (4). They also went on ahead to say that an ideal diet is one that promotes an increased consumption of vegetables, non-processed whole foods, and a reduced consumption of processed meat, added sugar and refined carbohydrates (4). The best diet also depends on each individual. So in simple terms, the best diet is one you can stick to while still offering the highest quality of foods. 

Most people adopt new diets in order to lose weight. Both the low carb diet and the vegan diet are known to promote weight loss if followed strictly. The problem with these two diets is that they can be too restricting to the point that it is hard to follow them for a long period of time. While having that similar, do not even think these two diets are anywhere close to each other. These two diets are very distinct as you will see in this well-informed read.

Low-Carb Vs. Vegan Diet: Vegan Diet

Most people usually wonder if the vegetarian diet and the vegan diet are the same thing. They are not the same. All vegans are vegetarians, but all vegetarians are not vegans (11). This is because while the vegetarian diet advocates for plant-based foods, there are some variations of the diet that allow for some animal-source products like dairy, honey and eggs (11). This is not the case when it comes to vegans. Vegans only allow plant-based foods into their diet and prohibit the consumption of any animal flesh and animal-related food including dairy, honey and eggs.

Some people go for a variation of the vegan meal plan where they eat all their food while raw. This is referred to as the raw vegan diet. Vegans eliminate all animal source products from their food. Their food is rich in vegetables, fruits, and whole grains. A vegan diet is usually low in fat, and it can be challenging to eat enough protein on a daily basis. Most foods in this diet are low-calorie foods. 

Vegans are believed to be thinner and healthier compared to omnivores. They are also said to have a lower body mass index (BMI) and also lower cholesterol levels. This is because their food mostly consists of fresh fruits and vegetables. Vegetables and fruits are great sources of vitamins, which are greatly needed by the body. They are also excellent sources of minerals and other nutrients essential for the human body. 

Most people promoting the vegan diet believe replacing animal source proteins with plant-based proteins decreases mortality and cardiovascular risk factors over a period of time.

Vegan Diet And Weight Loss

Is the vegan diet able to promote weight loss? If so, how does it do it? Are there facts to back any of these claims? The answer is yes, the vegan diet could be beneficial for weight loss. Based on the fact that vegan diets mostly support the consumption of foods with low calories, we can say that they promote weight loss. This helps create a calorie deficit leading to weight loss. Most vegetables and fruits contain high amounts of fiber. This makes them have an effect on one’s feelings (9). This makes a person feel satisfied longer, hence reducing their total energy intake per day. People who follow plant-based diets also show reduced risks of cardiovascular disorders. 

A study was conducted on a randomised controlled trial using a whole food plant-based diet in a community affected by obesity, ischaemic heart disease or diabetes (7). The participants of the study had the following characteristics: 

  • Aged between 35 and 70. 
  • Were obese or overweight and at least had either type 2 diabetes, ischaemic heart disease, hypertension or hypercholesterolaemia. 
  • They were 65 participants and 32 of them were put in the control group. The study took 6 months. 


After the six months, it was noticed that the individuals following the whole food plant-based diet had a more reduced BMI compared to the individuals following the normal diet. The individuals also had reduced cholesterol levels. This shows plant-based diets could lead to weight loss and help prevent or reduce some risk makers of cardiovascular diseases.

Low-Carb Vs. Vegan Diet: Low-Carb Diet

Since all there is to highlight on the vegan diet has been discussed. What is the low-carb diet? 

This diet is known to come in different names, some people refer to it as a ketogenic diet or a low carb high fat diet. This food plan emphasizes on rich sources of fat, moderate sources of proteins and a limited consumption of carbs. This particularly goes to mean most starchy vegetables, fruits and grains are largely excluded in this diet. The same cannot be said for the vegan food plan. In this diet you have to minimize your carb intake under all costs but increase your fat intake.

The idea behind most low carb high-fat diets is to force your body into a state of ketosis (3). Ketosis is a state in which your body uses fat for energy instead of carbohydrates. This diet involves removing carbohydrates from your diet until your body and brain are forced to utilise another form of energy as highlighted above. When you eat less than 50 grams of carbohydrates per day, which is what most people following a keto diet eat every day  your body eventually runs out of fuel, which is commonly known as glucose. This takes about three to four days to happen. After this, your body will start to break down fat for energy. This process of using ketones for energy, for fueling your body, is called ketosis. In simple terms, when you are in ketosis, your body will start breaking down and using its stored fats for energy. 

This diet is known to reduce risk factors associated with cardiovascular diseases. Most people use this diet to lose weight.

Low-Carb Diet And Weight Loss

The low-carb diet is able to promote weight loss. The rule for weight loss is to consume less calories than you burn. A low carb, high fat, moderate protein diet promotes weight loss in many ways. The burning of stored fat that is used for energy in such a diet also promotes weight loss as one is burning stored fat and using it for energy. Another way this diet promotes weight loss is by encouraging more intake of protein. Proteins promote muscle growth. Muscles have a higher resting metabolic rate than fat mass. This increased metabolism helps cut off those extra pounds. 

A study to determine if a low-carb diet is effective in reducing body weight was done (2). The study wanted to determine if weight loss would be achieved for healthy people and for people with type II diabetes. The study took 3 months. People were divided into four groups. 

  • Group 1
