How to Gain Weight Back After COVID -19

If you or someone you loved has suffered through COVID -19, I am so sorry. COVID-19 comes with so many side effects and complications including unintended weight loss. You may still be picking up the pieces and trying to get back to your pre-COVID health.

In this article we’ll discuss how to gain weight back after COVID-19. But first let’s look at why those with COVID-19 are losing weight.

Please note that we use the CDC for all references related to COVID-19. We use our expertise and experience as a Registered Dietitian Nutritionist for our tips on gaining weight.  

Symptoms of COVID-19

It seems like every one experiences COVID-19 a little different. Some people have no symptoms while others have mild symptoms. Then there are some who experience serve symptoms. Symptoms that can even land them in the hospital.

  • Fever
  • Cough
  • Difficulty breathing
  • Fatigue
  • Aches
  • Loss of taste or smell
  • Sore throat
  • Congestion
  • Nausea
  • Vomiting
  • Diarrhea

Severe symptoms requiring hospitalization include trouble breathing, chest pain, confusion, turning blue from not getting enough oxygen, or being unable to stay awake (1).

Because COVID-19 hasn’t been around for a very long time, there isn’t a ton of strong research. And there is a lot we don’t know. But new research is emerging. Let’s look at what we do know.

Loss of Taste or Smell with COVID-19

COVID-19 loss of taste and smellLosing the ability to taste or smell is often a tell-tale sign that someone is COVID-19 positive.

But how many people are actually impacted by this symptom of COVID-19?

Some people experience loss of taste or smell while others experience loss of BOTH taste and smell.

A research review article looked at 5 different studies with 10,818 people total. Of these patients, 81.6% lost the ability to taste. And 74.8% lost the ability to smell (2).

While new research continues to emerge, we know that this symptom is a hallmark of COVID-19.

Weight Loss in COVID-19

Unintended weight loss is being seen in COVID-19 patients being treated both at home and in the hospital. However, those with a more severe version of the virus are likely to lose the most weight (3).

One research article looking at hospitalized COVID-19 patients found that 37% of participants lost ≥5% of their body weight (4). This is a significant amount of weight loss. At this level, people are likely losing muscle.

Losing muscle can contribute to long term health issues and disability (4).

Malnutrition in COVID-19

Malnutrition is the loss of muscle and body fat. Research is showing that anywhere from 28% to 48% of hospitalized COVID patients are malnourished (4).

Some people are malnourished before getting COVID-19 and the virus (along with complications) can make the malnutrition more severe. Others become malnourished as a result of getting COVID-19.

Researchers have said that weight loss and malnutrition risk (losing muscle!) are likely an underestimated risk of COVID-19 (3).

How Does COVID-19 Cause Weight Loss

Whew, this was a lot of information. But how do these symptoms cause you to lose weight? There are many factors, but let’s dive into two of them. Loss of taste/smell and hospitalization.  

Losing Weight Due to Loss of Taste or Smell from COVID-19

enjoying food and flavorA big contributor to losing weight from COVID-19 is the common symptom of loss of taste or smell.

It may seem so minor compared to other symptoms, but it can have a serious impact on health.

When you have a mild to serve case of COVID-19, you just don’t feel well. That’s a simple fact. When we feel cruddy, we often lose our appetite. We don’t feel like eating because we feel so sick.

Now trying to eat when food tastes like nothing? That’s tough. At least when you feel cruddy the salty taste of hot chicken noodle soup or sweet taste of 7-up can make you feel something. Maybe comfort. Maybe a small sliver of joy.

Food is an important part of our mental wellbeing in addition to our physical wellbeing.

Not having taste or smell when combined with poor appetite from feeling sick = eating less. Or not eating at all. Not eating enough calories leads to unintended weight loss.

And we should mention that since your body is hard at work fighting COVID-19, you are actually burning more calories to start with.

Burning more calories from illness + not eating = more rapid weight loss.

Losing Weight Due to Hospitalization for COVID-19

Anyone with COVID-19 is at a higher risk of unintended weight loss. But those who end up being hospitalized are at an even higher risk. Usually those who are hospitalized have the more severe cases of COVID-19.

And their body is working extra hard to promote healing. This means the body is burning even more calories. And if they have an infection? Burning more calories. And if they end up being critically ill and on a ventilator? Burning more calories.

Being hospitalized increases risk of unintended weight loss. The hospitalized individual is battling illness, burning more calories than usual, and often not feeling up to (or being able to) eat.

Now there are good dietitians and hospital staff trying to get nutrients in hospitalized patients, but sometimes weight loss just happens. Especially with COVID-19.

How to Gain Weight Back After COVID-19

OK, that’s enough about WHY individuals are losing weight with COVID-19. There are many more factors and considerations, but this was a brief overview.

Now let’s dig into how to gain weight back after COVID-19.

Eat High Calorie Foods

Depending on how long it has been since you had COVID-19, you may be feeling great or you still may be feeling cruddy. But maybe you still haven’t gotten your taste back. And it’s hard to eat a lot of food.

To gain weight back after COVID-19 we recommend eating foods higher in calories. But it’s not just about volume. It’s not just eating more food. You need to eat the right types of food.

Different foods contain different amounts of calories. While eating a lot of food can leave you full, it doesn’t mean those foods contained a lot of calories. For example, you can fill up on a hug salad which actually contains a low number of calories.

Calories are key for weight gain. If you eat more calories than your body needs to function throughout the day, you will gain weight.

Which Foods Are High in Calories?

I’d be remiss in telling you to eat high calorie foods if I didn’t tell you which foods are high in calories. Typically, foods with a higher fat content contain the most calories. You can learn more about high calorie foods through our many articles on this topic: High Calorie Articles.

Foods high in calories that can help you gain weight include:

  • Whole fat dairy
  • Nuts
  • Seeds
  • Avocado
  • Peanut butter
  • Dried fruit
  • Salmon
  • Coconut
  • Etc.

Make a Plan

Once you figure out which high calorie foods you like, make a plan. Make a shopping list with the foods you need to stock in your home. Create a meal plan for what you will eat through out the day. And focus on eating multiple times throughout the day.

You can check out our High Calorie Foods SERIES for some tools to help you get more calories. You may also find our e-book Weight Gaining SECRETS helpful as you work to gain back weight after COVID-19.

And finally, here are some additional articles that mat be beneficial as you plan for weight gain:

How Long Does It Take to Gain Weight Back After COVID-19?

OK, eat high calorie foods. Gain weight. I know you get it, but you may be wondering how long does it take to gain weight back after COVID-19. Well, that depends.

Gaining Weight Back Fast

The more calories you eat, the faster you will gain weight. And you may want to get back to your old self as quickly as possible. I can totally understand that.

However, as a word of caution, don’t try to gain weight back too fast. Aim for gaining 1-2 pounds per week and gradually add back the weight. Also be sure to do strength training exercises to improve muscle strength.

We want to ensure you are gaining healthy weight. Meaning you gain back muscle and strength. And not just body fat or water weight.

How Many Calories to Gain a Pound?

3500 calories in a poundIt takes 3500 calories to gain one pound of weight. This is 3500 calories above what your body needs to function. This may seem like a lot, but if you break it down it seems more manageable.

Eating 500 extra calories per day should equate to gaining 1 pound in a week. Eating 1000 extra calories per day should equate to gaining 2 pounds per week.

You can see by these examples why it can be unrealistic to gain 5 or more pounds per week. That’s a ton of extra calories. And as mentioned above, it just isn’t good for your health.

Your body has been through enough with COVID-19. It will take time to regain any weight that was lost during this time. Just be patient and you will get there.

How Long Until Food Tastes Good Again After COVID-19?

If you lost your sense of taste or smell from COVID-19, you may be wondering when food will taste good again. Because everyone is different, only time will tell.

What the Research Says

Again, we don’t have a ton of research yet. But with up to 80% of patients with COVID-19 experiencing loss of taste or smell, I suspect we’ll see more research soon.

A small study with 202 COVID patients investigated those lost their sense of smell or taste. After 4 weeks of getting COVID-19, a total of 48.7% reported getting their taste or smell back. 40.7% had some improvement in taste or smell. And 10.6% saw no improvement (5).

We need more research to give more definitive answers. But hopefully this small study can give you a ball park estimate of when you may be getting your taste or smell back.

How to Make Food Taste Better

As you gain your sense of taste back you may be looking for ideas to make food more flavorful and delicious so you can get your appetite back! Here are some seasonings you can try.

herbs and spices for flavorful foodsSeasonings to add flavor to your food:

  • Garlic (fresh, roasted, or powdered)
  • Herbs (fresh or dried)
  • Spices
  • Lemon juice
  • Vinegar
  • Hot sauce
  • Horseradish
  • Flavor enhancers
  • Premade seasonings

When your appetite is poor, try eating smaller and more frequent meals. It can be hard to eat a full meal, so settle for a good snack every few hours throughout the day.

Conclusion

We covered a lot of information from why COVID-19 contributes to unintended weight loss to how to gain back weight after COVID-19.

Remember that it is a journey to gain back your weight and health after this virus. Make a plan, be patient, eat lots of calories, and slowly gain back that weight.
