2. Plant-based diets

Another popular weight loss diet plan is taking a plant-based diet. Veganism and vegetarianism are the two most popular versions of plant-based diets that limit animal products for ethical, health and environmental reasons.

According to several research, it is clear that plant-based diets are helpful in weight loss. An analysis of almost 12 studies that included 1151 individuals inferred that people getting on to plant-based diet lost around 4.4 pounds of weight on an average. This data was in comparison to the people who consumed animal products.

Plus, the ones who followed veganism lost around 5.5 pounds on average, which is more than people not on a plant-based diet.

This diet aids weight loss because the foods included are rich in fiber, which keeps you fuller for a long period of time and is low in calorie.

4. The Paleo Diet

5. Low-fat diets

Low-fat diets have also been popular over decades. To explain in easy words, low-fat diets is a type of weight loss diet that restricts fat intake to almost 30% of your every day calories. Some ultra-low fat diets encourage limiting fat consumption to less that 10% of your daily calorie intake.

How the diet works

Low-fat diets limit your fat intake as fat gives you twice the number of calories every one gram in comparison to the other two macronutrients – carbs and protein.

Despite being effective for weight loss in controlled situations, people opt for low-carb diets over low-fat diets.

Ultra-low fat diets are also successful, mainly in people having the problem of obesity. In an 8-week study that included 56 people, health experts concluded that following a diet with 7-14% fat result in a weight loss of 14.8 pounds on an average.

Additional benefits

Low-fat diets help in reducing the risk of stroke and heart disease. They can also help improving the markers of diabetes and reducing inflammation.


Restricting too much fat can result in various health problems in the long run. The reason is that fat is essential for nutrient absorption, hormone production and cell health. Additionally, going into very-low fat diets can lead to an increased risk of metabolic syndrome.
