Some of you may be wondering, what is a weight gain diet? A weight gain diet is not a new diet trend or an exact way of eating. Rather, a weight gain diet focuses on a way or strategy of eating. It focuses on eating to increase overall calories. This in turn increases weight safely, effectively, and sustainably.

Why Would Someone Need to Gain Weight

In today’s culture, weight loss is a more popular topic than weight gain. It seems like so many people are looking for the next best diet or food to eat in order to lose weight. However, there are many individuals who would not benefit from weight. In fact they may need to gain weight to improve their health.

This blog will dive into who may need to focus more on weight gain versus weight loss. And how to effectively and sustainably implement weight gaining foods and strategies!

Advancing Age

As adults age, they experience “sarcopenia”. Sarcopenia is the natural, involuntary loss of muscle mass, strength, and function. The rate of muscle loss can be increased or decreased depending on many lifestyle factors such as food and exercise choices.

Sense of hunger often decreases with age. Older adults may consume less food as they reach satiety (get full) faster. Changes in eating habits as well as decreases in activity (due to disability, difficult moving, and other health conditions) has an affect on muscle loss and muscle function.

Weight loss can also occur due to chronic diseases or illnesses including anxiety, depression, kidney disease, dysphagia (difficulty swallowing), and more that will be discussed later. These conditions can make it difficult to physically eat (like dysphagia and Parkinson’s disease). Or they can affect one’s appetite and what they can and cannot eat. This in turn affects how much food is consumed.

However, it is important for older adults to continue healthy dietary patterns and to maintain their body weight. Unintended weight loss can lead to muscle loss increasing the risk of falls, illness, or other health conditions.

Medical Conditions

There are many medical conditions that can cause weight loss. Below is a list of many different conditions that could cause unintentional weight loss. Individuals with these conditions may benefit from higher calorie foods to stop unintended weight loss and promote healthy weight gain, as applicable.

What Foods are Good for Weight Gain?

There are a lot of different foods that provide greater calorie content that can be mixed and matched to create delicious meals and snacks. Although the foods listed below are all good recommendations for weight gain, some medical conditions may require you to limit particular foods. Always be sure to work with your healthcare team (provider, dietitian) to make sure you are eating the best foods for you.

Overall, weight gain occurs with the more calories you consume. So a simple goal for gaining weight is effectively may be increasing either the amount of food consumed or the number of calories in each meal.

Fats for Weight Gain

Fats are very energy dense (read= high in calories) and are a great way to add more calories into a meal. They have more energy per gram than both carbohydrates and protein which makes them a great option for increasing caloric content.

Here are some examples of high fat foods that you could incorporate into meals or snacks to help increase caloric content.

  • Nuts and Nut Butters
  • Flax Seed
  • Avocado
  • Coconut
  • Cooking Oils
  • Salmon/fatty fish

Protein for Weight Gain

Protein, especially lean protein, helps to build muscle which in turn can help you gain weight. And any excess protein consumed beyond what your body needs will be stored as fat, in turn increasing weight gain. Some example of high protein foods good for weight gain are listed below.

You will notice that protein sources that also contain some fat are good for weight gain. In general, this is why dairy products can be good for weight gain. The whey protein and fat combination are good for weight gain.

  • Oily fish
  • Protein Bars
  • Whole Milk
  • Cheese

Carbohydrates for Weight Gain

When looking at the best carbohydrates for weight gain it is good to focus on whole grains and starchy vegetables. Adding fats like butter or olive oil can help increase the caloric content of these foods.

  • Whole Grain Bread
  • Rice
  • Pasta
  • Breakfast Cereals
  • Potatoes

Strategies for Weight Gain

  • Eat frequently: If you find that it is hard to consume a lot of calories in one sitting because you get full too quickly or some other reason, try to instead many smaller meals throughout the day, eating about every 2-3 hours.
  • Choose energy dense foods: When choosing foods to eat, choose foods that are energy dense (high in calories). Eating smaller, more energy dense meals can make it easier to get in more calories.
  • Avoid Drinking Before/During Meals: Drinking large amounts of water or other low calorie beverages right before consuming a meal may fill you up and prevent you from eating enough during the meal.
  • Try Smoothies and Shakes: Smoothies and shakes can be a great way to get in more calories without getting as full quite so quickly. Drinking in calories can make is easier to eat more.
  • Add Extras: High calorie add-ins can make a regular meal a high calorie meal. For example, if you are making oatmeal, try to add in some nut butter to add in some extra calories.

Maintaining the Weight Gain

Weight gain should be achieved slowly. Gradually increasing calories over a period of time to promote healthy weight gain. This will hopefully lead to more sustainable weight gain.

Once you find the best weight for your body to function properly and efficiently, then you can stop increasing calories. But you need to be cautious, ensuring you still consuming enough calories to prevent weight loss. Regularly checking your weight is the best way to make sure you are no longer losing.

We hope the weight gain food list and information provided in this article helps you to gain and maintain your weight. Best of luck!
