Nutritional yeast is a nutritional supplement that offers additional protein, iron and B vitamins. It’s shut down, unlike the yeast used to bake bread, but it’s still a fungus. An advised serving size of dietary yeast includes about 60 calories, which is unlikely to cause substantial weight gain. If you include the yeast to calorie-dense foods or eat multiple portions each day, however, you might wind up with a larger waistband.

Weight Gain Basics

In most instances, you gain weight since you consume even more calories than you burn. If you consume an extra 3,500 calories more than your body uses up with everyday living and physical exertion – you’ll gain a pound. With 60 calories per 2-tbsp. serving, if you add nutritional yeast to your maintenance calorie needs without changing anything else, you can obtain 6 pounds during a year or about 0.1 pounds every week.


If you’re including 2 tablespoon. of dietary yeast at several meals and treats, those calories can accumulate. 3 servings each day adds up to 180 calories, which might cause you to get 0.4 pounds in a week, or about 1.5 pounds in a month. You don’t need multiple servings of the yeast daily to reap its advantages. A 2-tbsp serving of strengthened yeast provides even more than 100 percent of your day-to-day needs for the majority of the B vitamins, 4 g of fiber, 9 g of protein and 20 percent of the daily value for iron, based upon a 2,000-calorie diet plan.


If you included nutritional yeast to your diet and experience weight gain, think about various other potential causes. You may be adding dietary yeast to popcorn, smoothies, soups, pasta, eggs or stir fries. If you didn’t previously consist of these foods in your diet, including them as a way to eat dietary yeast might be the source of your additional calories. As an example, if you added an everyday healthy smoothie with 2 tbsp. of yeast, 1 ripe banana, 1 cup of fruit and 1 cup of milk – you increased your calorie consumption by 350 calories. A 350-calorie addition lead to a 0.7-pound weekly weight gain – certainly visible over the course of a month or more.


Keeping a food journal may help you recognize the source of the extra calories that’s triggering weight gain. Adhere to just one serving of dietary yeast per day and ensure that you count it as part of your overall everyday intake. If you make use of nutritional yeast numerous times each day, try reducing your intake at each sitting – simply 1 tsp adds a cheesy taste with only 20 calories.
