To lose weight on a vegan diet, you’ll first want to calculate your calorie needs. It may also help to track your food intake for a few days to ensure that you’re on the right track with your daily calorie intake (1).
Assuming you find the right calorie level, a vegan diet can be a great choice for weight loss.
In one small study of 50 overweight adults, participants following a vegan diet lost significantly more weight at six months than those on an omnivorous, semi-vegetarian or pesco-vegetarian diets (2).
This finding is consistent with other randomized controlled trials that have found vegan diets to be more effective for weight loss than other diets low-fat omnivorous diets. Researchers in at least one study have associated this difference in fat loss with higher intakes of plant protein and lower intakes of animal protein (3, 4).
What’s more, you may not even need to give up animal products entirely to see weight loss benefits.
In another small study, participants on a vegan diet lost more weight than those on an omnivorous one after six months, even when they weren’t 100% compliant. While veganism is often perceived as a restrictive diet, adherence rates were just as high for vegans in this study as they were for omnivores (5).
In other words, a mostly vegan approach can still help you lose weight if you’re concerned that you won’t be able to stick with a vegan diet.
Summary: A vegan diet is one that excludes all animal products, including meat, dairy, fish and eggs. Like any successful weight loss plan, you’ll need to eat fewer calories than you burn if you want to shed pounds on a vegan diet. However, studies suggest that vegan diets may be superior to omnivorous ones for weight loss, even when you’re not always 100% compliant.
Protein on a Vegan Diet
Though total calorie intake is the best predictor of weight loss, it’s important to eat enough protein on a vegan diet weight loss plan.
The benefits of high protein intake have been seen in omnivorous diets, but studies suggest that plant-based proteins may be especially helpful for fat loss.
In one 16-week study, 38 participants were randomized to a vegan diet and 37 participants were instructed to continue eating normally. Vegans in the study lost an average of 4.3 kilograms (9.5 pounds) of fat mass.
Researchers credited the exchange of plant proteins for animal proteins with more than half of this fat loss. Specifically, participants in the vegan group:
- lost an average of 0.04 kilograms (0.09 pounds) of body fat for every 1-gram reduction in animal protein intake
- lost an average of 0.046 kilograms (0.1 pound) of body fat for every 1-gram increase in plant protein.
All told, the vegan group lost a total of 2.33 kilograms (5.1 pounds) of body fat in 16 weeks, just by changing their protein sources (8).
The dietary reference intake for protein is 10-35% of calories, or 38 to 131 grams per day on a 1500-calorie diet. Critics of vegan diets argue that it’s difficult to obtain adequate protein for weight loss and health, and that’s simply not true. Vegans do, however, need to be more thoughtful about including a quality protein source at each meal.
Unlike animal proteins, most plant proteins are not considered to be complete sources of protein. This means that the food is deficient in one or more of the 9 essential amino acids.
Vegans can compensate for this deficiency by including foods that are high in the amino acid that’s lacking. For example, beans are low in an amino acid called methionine and grains are lacking in an amino acid called lysine. These foods are called complementary proteins. Eating them together, such as spreading beans on toast, will provide a balance of essential amino acids.
Fortunately, you don’t always need to pair complementary amino acids at each meal. Eating a variety of vegan protein sources will help ensure that you get the amino acids that you need to be healthy. Beans, legumes, grains, seeds, and nuts are all good plant-based sources of protein.
And though there are very few of them, vegans should also be sure to include plant-based complete proteins in the diet. These include soy, quinoa, mycoprotein and seitan.
Summary: Higher protein intake may promote weight loss by curbing the appetite. Vegans have fewer options for protein than omnivores but can obtain plenty of protein with some planning. Foods like quinoa, mycoprotein, seitan, and soy contain all 9 essential amino acids in adequate amounts and are great options for vegans. Vegans should also eat a variety of protein sources to ensure that they are getting all 9 amino acids.
7-Day Vegan Diet Weight Loss Plan

You’ll also need to check ingredient labels on packaged foods to check for any hidden animal products.

Is a Vegan Diet for Weight Loss Right for You?
A vegan diet has been shown to be effective for weight loss, even if you don’t follow it perfectly all the time.
Studies indicate that it may even be superior to omnivorous diets or other plant-based diets for weight loss.
Like any weight loss plan, though, total calorie intake and diet quality are the best predictors of weight loss.
It’s very possible to gain weight on a vegan diet if you’re eating too many calories overall, or if you’re eating a lot of junk foods.
It’s also important to obtain enough protein on a vegan diet weight loss plan.
Doing so will help preserve muscle mass, and it may also help naturally curb appetite.
Veganism is a natural fit for people who prefer to avoid animal products for ethical, religious or environmental reasons.
However, you might be more interested in a flexitarian diet if your main goal is weight loss and you’re worried that veganism might be too extreme for you.
After all, the most effective diet for you is the one that you can stick with for the long run.
