Weight Gain Milk: A Fortified Food to Gain Weight 

“Weight Gain Milk: A Fortified Food to Gain Weight” was reviewed/edited by Aly Bouzek, MS, RDN.

Milk, specifically weight gain milk, is a great tool for stopping unintended weight loss and promoting weight gain.

Weight gain milk is actually a “fortified food” that provides extra calories to the foods and drinks that you are already consuming.

This article provides information on how to make weight gain milk, tips to promote weight gain, and recipes. Read on to learn more!

What are Fortified Foods?

Fortified Foods

By definition, “fortify” means to “strengthen”.

As it relates to foods, fortify means to increase the amount of nutrition in the food.

Fortified foods are simply foods that we add extra nutrients to.

This can be in the form of micronutrients (vitamins and minerals) or macronutrients (calories, protein, fat).

Fortified with Vitamins and Minerals

Most people are familiar with fortified foods that have been fortified with vitamins and minerals. A good example of this is juice. Some orange juice brands are fortified with calcium. 

Another example is actually milk itself. Milk usually has vitamin D added to it. This is a nutrient that isn’t naturally found in milk. So, we now know that milk is fortified with vitamin D.

Milk Nutrition

Milk has calcium, vitamin A, and is fortified with vitamin D. These nutrients are important for eye health, bone development, and our overall health. 

Fun fact! Milk is known as a good source of calcium, but did you know that without vitamin D our bodies have a hard time absorbing and using that calcium? 

Fortifying milk with vitamin D was an effort to help our bodies absorb the calcium in milk, have stronger bones, and avoid rickets (a disease caused by vitamin D deficiency). (1)

Fortified with Calories

When a geriatric dietitian talks about fortified foods, we are usually talking about foods that have been fortified with calories. This means that we are adding extras to foods someone is already eating to maximize the calories eaten.

Providing fortified foods is an effective strategy to stop unintended weight loss and promote weight gain. It allows us to maximize the calories with the same amount of foods consumed.

We do this so that you don’t get full from eating so many extra calories! Instead, you can enjoy the same amount of food, now with a boost of extra calories. 

Using Milk to Gain Weight

Milk can be consumed with a meal or in-between meals to help with weight gain. Sometimes people can get too full while drinking a lot at meal times. Drinking milk in between meals is most effective. 

Calories in Milk

There are many different varieties of milk. For the purpose of this article, we are discussing pasteurized cow’s milk. But even within cow’s milk there is lots of variety.

When making Weight Gain Milk we need to make sure we are using the varieties of milk with the most calories.

If you want to add dry whole milk to make it a weight gain milk smoothie, then remember to use the 4:1 ratio that we learned about above! 

Quick tip: add up all liquid amounts and divide by 4. The number you get is how much dry whole milk you should add to a recipe.

Quick example: the liquids in the recipe are 1 cup of milk and ¼ cup half and half. 1 cup + ¼ cup = 1.25 cups. Divide 1.25 by 4 and you get 0.3 or about ⅓ cup dry whole milk. Great work!
