Top 7 Most Effective 2021 Diets


One of the best ways to lose weight is by choosing to consistently follow a healthy diet. There are several diet plans available, but not all of them provide the desired results. Some diets help to curb your intake of unhealthy food, while other diets help to restrict the number of calories you consume in a day. So if you are searching for ways to reduce weight, keep on reading this blog. The following is a list of the 7 most effective diet plans for 2021.


1.    Intermittent Fasting

This strategy transitions between fasting and eating. There are different ways you can choose to adjust to this method. For example, you can skip eating for 8 hours during the day and consume food afterward in restricted amounts.

How It Works

Since the fasting method restricts the time that you’re allowed to eat food, it is a quick way to lose weight because your calorie intake is significantly reduced. This results in subsequent weight loss (unless you decide to overeat after the 8-hour restriction).


This method has shown positive results in the past and has caused about 5 to 8% of weight loss over the course of 3 to 6 months. Plus, the overall belly fat is also significantly reduced due to increased metabolism and fat burning.

2.    Vegetarian Diet

Vegetarian diets can also help you lose a substantial amount of weight. This diet plan restricts you from consuming animal products, such as meat, poultry, and fish for environmental and health-related reasons. However, some vegetarian diets provide the flexibility of consuming meat in moderation.

Moreover, another version of this diet is the vegan diet. Vegan diets eliminate meat-based products and dairy products altogether. There are no pre-defined rules regarding the vegetarian diet plan, so you can choose whichever option suits you the most.

How it Works

This diet plan encourages consuming healthy foods like fruits, vegetables, lentils, etc. If you want to go vegan, you’ll have to avoid having eggs and milk in breakfast. You can modify it according to the number of calories you want to consume each day.


The vegetarian diet has provided several benefits, such as preventing the risk of heart disease, certain types of cancers, and diabetes. The only downside of this diet is that your body might become devoid of some important nutrients. Thus, it is recommended to eat meat products in moderation or take supplements to ensure the supply of nutrients.

3.    Low Carb Diets

Low carb diets are very popular among people who want to lose weight. The Keto diet is one of the most famous low carb diets. It aims to eliminate all forms of carbs from the daily food intake. Low carb diets are usually high in protein because it helps to curb cravings that can so often ruin a person’s diet efforts.

How it Works

There are several low carb diet plans available. Most of them have weekly meal plans that tell you what to eat at each meal and between meals. The plan is different for each day and usually includes easy-to-cook homemade dishes.


Low carb diets have proved to be more effective compared to other types of diets for weight loss. These diet plans also help to reduce the risk of heart disease and diabetes because of the reduced intake of carbs and fats.

4.    The Paleo Diet

The idea of the paleo diet dates back to the time of our ancestors. Many advocates of this diet claim that the human body has not completely evolved to process the consumption of grains, dairy, and processed food, so consuming vegetables and unprocessed meat is the way to go.

How it Works

This diet focuses on eating healthy food such as fresh vegetables, unprocessed meat, fruits, nuts, and seeds. It also restricts the consumption of processed sugar, grains, and dairy. However, there are different versions of the paleo diet that allow consumption of some dairy products, including cheese.

The great thing about the paleo diet is that it does not completely starve you because it does not restrict the amount of food you eat (provided that you only eat healthily).

5. Low-Fat Diets

Low-fat diets are also popular among many people. The main purpose of this diet is to restrict or eliminate the intake of fat in a day.

How it Works

Fat provides twice the number of calories compared to other food. Low-fat diets restrict the intake of fat to about 30% on a daily basis. Some advanced versions of this diet aim to restrict the intake of fat to as low as 10% on a daily basis. The remaining calories mainly come from protein intake.


Low-fat diets are a great way to reduce significant weight as it mainly focuses on consuming fat-free food. This diet also helps to reduce the risk of developing diabetes and other harmful fat-related diseases. It also helps people who suffer from extreme obesity and find it difficult to lose weight through other means.

6.    The Mediterranean Diet

The Mediterranean diet was originally designed to reduce the risk of heart disease. It is based on eating foods that people in countries like Greece or Italy used to eat. However, studies have proved that the Mediterranean diet also helps to reduce weight.

How it Works

This diet mainly focuses on consuming fruits, vegetables, nuts, seeds, legumes, whole grains, fish, and other seafood. The amount of red meat is restricted; whereas, poultry and dairy products are taken in moderation.


The Mediterranean diet does not show instant results. It takes several months to see a major difference in the overall body weight. Additional benefits of this diet include a reduction in inflammation and stress levels. It also prevents heart disease and some types of cancers.

7.    Weight Watcher Diet

This diet is becoming increasingly popular among people who are conscious about their weight and those who aspire to lose weight quickly.

How it Works

The weight watcher diet does not restrict the intake of any food groups. Instead, it has a point-based system that allows you to calculate your daily calorie intake according to the points associated with each food group. For instance, there will a certain point limit to the consumption of a sweet beverage. In order to reach your desired goal weight, you must not exceed the point limit.


The weight watcher diet is very effective in losing weight instantly. The only downside of this diet is that it is difficult to maintain consistency as many people find it hard to stay within the point limit.


All of the above diets are great for weight loss; however, the type of diet you choose should be based on your lifestyle, age, current weight, target weight, and gender. There are several other factors involved as well, such as your daily activity level and other health-related conditions.
