How To Become A Vegan To Lose Weight

“How do you become a vegan to lose weight and get healthy?” you may ask? Well, there’s no one way to go about it. It all depends on your personal preferences. For example, if you’re not an ovo-vegetarian, or lacto-vegetarian, or etc., then you need to talk to your doctor first before making the switch.

Being vegan is a healthy diet. It’s also good for the environment, as eating less meat and dairy can reduce your carbon footprint and save valuable resources like water and energy. Lastly, it might even help you to lose some pounds. But, I have to warn you, being a vegan is not an easy lifestyle. So, only consider if you feel that you’re up for it!

If you’re trying to lose weight, a vegan diet may be the answer. A variety of studies have shown that vegans generally have lower BMIs than their non-vegan counterparts. From time to time, vegans are stereotyped as munching on twigs and berries — but nothing could be further from the truth. While it’s true that some vegans do eat foods quite high in fat (like avocado,) other types of vegan diets are actually very low in fat. Popular blogger Dreena Burton provides one such example with her vegan “high raw” diet, which involves eating mostly fruits and vegetables with little added fat or sweeteners. If a raw diet is too extreme for you, simply keep your foods whole.

How do vegans lose weight fast?
Vegans can lose weight quickly if eating a whole food plant-based diet. This involves eating foods in their whole, unprocessed forms such as fruits, vegetables, whole grains, beans, nuts and seeds. These foods are high in nutrients but low in calories compared to standard Western diets. This can allow vegans to easily be in a calorie deficit and lose weight rather quickly.

Can you lose weight going vegan?
While many people to see an initial weight loss by switching to a vegan diet, it is not guaranteed. It largely depends on what you were eating previously and what you eat after going vegan. If you started out eating processed junk food and simply switched to vegan junk food, you most likely won’t see weight loss. However, a healthy plant-based vegan diet can be beneficial in weight loss and weight maintenance.

How long does it take to lose weight on a vegan diet?
Some people see weight loss after their first week eating vegan. Eating a healthy plant-based vegan diet can provide fast weight loss results if done properly.

Should you increase protein in a calorie deficit?
Research shows that high-protein intake during weight loss has been found to have negative metabolic effects, which undermines the improvement of insulin sensitivity from weight loss.

If you’re worried about muscle mass, the best way to preserve muscle mass during weight loss is through exercise. Including resistance training, even just a few times a week, can help prevent more than 90% of the loss of lean body mass (muscles) during caloric restriction.

If you do want to add some additional protein to your diet, you can use a plant-based protein powder (such as this homemade pea protein, made from yellow split peas). Just make sure that there’s no added sugar if buying it from the store.

Why you’re not losing weight on a vegan diet
There’s a common misconception that vegan = healthy. In reality, vegans can fall on the broad range of healthy to unhealthy diets just like any omnivore diet.

A lot of that boils down to processed vegan foods. Vegans can eat chips, cake, cookies, soda, mock meats and cheeses. Just because it’s vegan doesn’t mean it is healthy.

The plus side is that a vegan diet can absolutely aid in weight loss if done in a healthy and sustainable way. After all, you want to keep the weight off don’t you?

Now, everyone knows the basics like to cut out processed foods, drink more water, etc. But actually putting advice into action is the hard part.

We’re going to dive into the best tips and strategies for weight loss on a vegan diet so you can lose weight, feel great, and stop yo-yo dieting.

Disclaimer: Make sure to check with your primary care physician before starting a new diet, especially if you are currently taking medications.

How to lose weight on a vegan diet
Weight loss as a concept is really quite simple. If you burn more calories than you consume (food and drinks), you’ll lose weight. Easier said than done.

Let’s start with ways we burn calories: resting metabolic rate (the calories we burn just to stay alive like pumping blood or growing new cells), non-exercise physical activity (standing, walking around the house, doing laundry, cleaning, etc.), exercise, and diet-induced thermogenesis (the energy it takes to digest the food we eat).

Average Calories Out: 60% Resting Metabolic Rate, 25% Non-Exercise Physical Activity, 10% Diet-Induced Thermogenesis, 5% Exercise
Exercise accounts for only 5% of the calories we burn. This is why we can’t outrun a bad diet.

To burn off one donut you’d have to walk for close to an hour or run for 23 minutes. Plus, exercise, especially high intensity ones, rev up our appetite and can actually cause us to eat more and unintentionally move less over the following few days. There’s no need for intense exercise, but a little daily movement is good for health in general.

The good news is you can lose weight without exercise or spending hours in the gym. Move more, but don’t make it your main source of calories out for weight loss.

Take a 30 minute brisk walk a few times a week or do some light weight resistance training.

And the best time to workout? In the morning before a meal if possible, tends to burn the most fat.

If you can’t, the next best time is 6 hours after a meal like before a late lunch or before dinner time if you had an early lunch.

Why? Carbohydrates are the preferred fuel for our bodies which means after a meal they get broken down and converted into blood sugars.

Our muscles then use them for fuel without needing to rely much on our energy stores of fat. However, when exercising fasted, our muscles dip into our energy stores so we burn more fat while exercising.

So how do we maintain a calorie deficit without focusing on exercise? Focus on the calories in side of the equation. Eat less than you burn. Not sure how many calories you need a day? Check out this calorie calculator to get an estimate.

Read on for the best tips to help you maintain a calorie deficit more easily on a vegan diet.

Fiber is zero calories but filling and nutritious. Fiber is indigestible meaning our body can’t absorb it and is often just thought of helping us with regular bowel movements. However, we have billions of little helpers in our colon in the form of bacteria that can digest fiber.

When our good gut bacteria break down fiber, they turn it into short-chain fatty acids (SCFAs) that can be absorbed into our bloodstreams and bodies. These SCFAs play an important role in regulating our appetite, metabolism and body fat.

When we increase our fiber intake it also leads to a decrease in daily caloric intake. Why, you ask? The fiber adds bulk to food, but not calories, so we fill up on less calories per volume.

For example, one study showed that a high-fiber whole wheat pasta with pureed fruits and vegetables left the stomach 45 minutes later than a meal with the same volume and same calories but made with white pasta and fruit and vegetable juices (with fiber removed).

This slower emptying of the stomach leads to a longer feeling of fullness and less calorie consumption at later meals.

Additionally, fiber can act as a natural fat- and starch-blocker. When you eat apple slices with peanut butter, some of the peanut oil calories get trapped in the fiber from the apples and make it all the way through the intestine without getting absorbed.

A Standard American Diet loses about 5% of the calories in waste but a diet higher in fiber can double that. This means you can lose more weight eating a high-fiber diet with the same number of calories.

On a Standard American Diet, people get less than half the recommended daily fiber. If you increase fiber intake to the minimum recommended amount of about 30 grams a day, it could potentially decrease daily calorie absorption by one hundred calories!

Additionally, choosing higher fiber foods also helps to crowd out the less filling, processed foods. It’s a win-win!

Fiber is only found in plants. Here are some high fiber options:

Beans and legumes (kidney beans, chickpeas, black beans, lentils, etc.)
Whole grains (quinoa, oats, whole wheat, etc.)
Nuts and seeds (almonds, walnuts, chia seeds, sunflower seeds, etc.)
Fruits (avocados, pears, apples, etc.)
Greens (kale, broccoli, Brussels sprouts, etc.)
Root vegetables (sweet potatoes, onions, beets, carrots, etc.)
Ditch the white bread and opt for whole grain bread. My favorite is Ezekiel which is a sprouted grain bread. No add oil or sugar and full of high fiber grains!

Same goes for pasta. Choose pastas made from 100% whole wheat or other whole grains.

These easy swaps make increasing fiber intake a breeze!

Avoid liquid calories by drinking more water. Liquid calories like sodas, juices, energy/sports drinks, and alcohol can be high in empty calories and sugars which throws off your metabolism.

Don’t like plain water? Try adding a squeeze of lemon or lime like this Lime Agua Fresca. Add fresh mint or berries to flavor water naturally.

Eating foods high in water content also adds bulk much like fiber does. Apples and oranges, for example, are about 85% water. Since they are low calorie but bulky, you can fill up on them quickly without consuming a lot of calories.

High-water foods also tend to take longer to chew and eat, which sends signals to our body that we’re getting full and in response regulates our appetite.

Oil is essentially pure fat. It’s stripped of fiber (and most of the nutrients that are attached to fiber). One tablespoon of olive oil contains 120 calories of mostly empty calories.

Eliminating oil is an easy way to reduce calorie intake. When cooking, simply replace oil by sautéing with water, vegetable broth, balsamic vinegar, or soy sauce. The latter three also provide great flavoring without as many calories as oil!

All the recipes at Health My Lifestyle are designed oil-free. You’ll be surprised how much you don’t miss oil when you stop cooking with it.

Eliminating added oils also applies toward packaged foods. If you see oil on the label, skip it. Most likely it’s highly processed, low in nutrients, and high in calories anyways. That’s a recipe for disaster if you’re trying to lose weight.

Stick with the source of oil: the whole olive, peanut, avocado, etc. Eating the whole food provides the healthy fat we need along with the fiber and nutrients for a healthy diet.

Refined sugar is much like refined oil, devoid of nutrients and full of empty calories. Most packaged foods will have added sugar in some form.

Check the nutrition label for added sugars. If you see it, skip it.

To be clear, added sugar is not the same as naturally occurring sugar. Sugar found naturally in fruits should not be avoided.

Eat all the fruit you want! It has fiber to help blunt spikes in blood sugar. And as we’ve learned, high fiber foods aid in weight loss!

There’s a saying that you should eat breakfast like a king, lunch like a prince, and dinner like pauper.

What does it mean? Front-load your calories in the morning and have a large breakfast, then a medium-size lunch, and a small dinner.

Research found that eating 70% of your daily calories split between breakfast, morning snack, and lunch, leaving 30% for an afternoon snack and dinner, increases weight loss.


Calories eaten in the morning are more likely to be burned off due to diet-induced thermogenesis (the energy required to digest food). This is because in the morning our bodies are using energy to string together glucose molecules from the food into chains of glycogen to store in our muscles for later use throughout the day.

The extra step of assembling and disassembling glycogen takes energy that our bodies take from the meal, leaving us with fewer net calories. Pretty incredible right?

Slowing down the rate at which we eat food improves satiety. Make sure to chew food thoroughly, take your time with soup, and sip smoothies slowly.

If we eat too quickly, our body doesn’t have enough time to send the signals that we’re getting full, which can lead to overeating.

Take your time and savor those meals!

When hunger strikes, it’s nice to have meals prepared within arm’s reach in the fridge or freezer rather than succumbing to cravings and ordering vegan take-out. I find meal prep saves me tons of time throughout the week.

Set aside a little time each week to plan out your meals. You don’t have to plan every single thing you eat (unless you want to), but having just the main meals planned and shopped food can ease the stress of eating healthy throughout the week.

Look for recipes online or in cookbooks that are based around whole foods and no added oil. Make sure they sound appealing to you—don’t just pick them because they’re healthy. There’s no need for willpower when you have a delicious meal ready in the fridge that you’re looking forward to!

If you need help finding tasty and healthy recipes check out the Health My Lifestyle Meal Planner. Most recipes can be made in 30 minutes or less so you can meal prep easily without spending tons of time in the kitchen. The customizable meal plans also make it easy to fit your taste preferences and schedule.

Why am I gaining weight as a vegan?
There can be various factors affecting weight loss as a vegan. It depends on what you’re eating (processed foods) and how much you’re eating. If you are overeating, regardless of what you’re eating, you will gain weight. Take note of your diet and see if there are any improvements you can make to lower your caloric intake.
