Do Cravings Change With COVID-19? | What Your Appetite Means

Yes, cravings can shift with COVID-19, often because smell and taste changes, fatigue, nausea, and routine changes alter what feels appealing.

If food suddenly feels “off,” cravings can feel like they’ve taken the wheel. One day you want salty snacks, the next you can’t stand the smell of coffee. If this started around a COVID-19 infection, it has a few clear explanations.

You’ll learn what can drive craving changes during COVID-19 and recovery, how to eat when flavor is weird, and when a craving shift is a sign you should get checked.

Do Cravings Change With COVID-19? What Research Shows

COVID-19 can change appetite in more than one way. Some people lose interest in food. Others get strong pulls toward sweet or salty foods, crave cold items, or stick to one “safe” meal that doesn’t taste awful. A major driver is smell and taste disruption, which appears on the CDC’s COVID-19 signs and symptoms list.

When smell drops, flavor goes flat. That can nudge you toward foods that still “register” on the tongue: salt, sugar, sourness, heat, crunch, or creamy texture. Some people get the reverse, where familiar foods taste burnt, metallic, or chemical. NHS inform notes that taste and smell can change after COVID-19 and that foods may taste bland, salty, sweet, or metallic, which can affect appetite and intake (NHS inform on long COVID smell or taste changes).

Smell can also linger. A study in JAMA Network Open on long-term taste and smell outcomes reported that objectively measured taste dysfunction was absent at one year, while smell loss remained in nearly one-third of participants with COVID-19 exposure. That pattern fits what many people report: “taste” feels wrong because smell still isn’t back to normal.

Why COVID-19 Can Shift What You Want To Eat

Smell does most of the flavor work

Your tongue detects sweet, salty, sour, bitter, and umami. Most of what you call “taste” is aroma traveling up into the nose while you chew. When COVID-19 affects smell, food can feel dull. When smell returns in a distorted way, certain foods can suddenly feel disgusting, even if your mouth “taste buds” are fine.

Throat and nose symptoms push you toward easy textures

A blocked nose cuts down aroma. Dry mouth from fever or dehydration can make salty snacks feel more satisfying because they stimulate saliva. A sore throat can make you reach for soft, cold foods like yogurt, smoothies, or ice pops since they slide down with less friction.

Stomach symptoms narrow cravings fast

Nausea, vomiting, and diarrhea show up for some people with COVID-19 and can make cravings collapse into a short list of bland foods. That’s not a character flaw. It’s your body steering you toward what it can tolerate.

Fatigue changes the “effort budget”

When you’re wiped out, cooking can feel like a mountain. Cravings often drift toward ready-to-eat food, sweet snacks, and anything that feels comforting. When your routine is off, meal timing can slide too, which changes what sounds good.

Common Craving Patterns During And After COVID-19

Not everyone gets cravings, and not everyone gets the same ones. Still, a few themes show up often.

• Sweet pulls: cookies, cereal, chocolate, sweet drinks.
• Salty pulls: chips, ramen, pickles, crackers.
• Cold foods only: smoothies, ice cream, chilled fruit, yogurt.
• Crunch seeking: toast, pretzels, apples, granola.
• Spicy or sour swings: hot sauce, citrus, vinegar-based snacks.
• Safe foods on repeat: a short set of meals that don’t trigger nausea or weird flavors.

Smell and taste changes can flip cravings either way. Some people chase stronger flavors because bland food feels pointless. Others avoid strong flavors because they taste “wrong.” Both reactions make sense.

What Changes In Cravings During COVID-19 And After Recovery

Timing helps you interpret what’s going on. Cravings during the first week can look different from cravings a month later.

During the infection

Appetite often drops with fever, sore throat, congestion, or nausea. If you crave something, it’s often tied to comfort and ease: soup, toast, tea, fruit, popsicles. When smell drops suddenly, you may want stronger salt or sugar just to feel flavor.

In the weeks after

As energy returns, cravings can come roaring back. Your body may be catching up on calories, protein, and fluids. If smell is still muted, you may chase texture and temperature: crunchy, creamy, hot, icy. If smell is distorted, you may stick to foods that still taste normal.

When symptoms last for months

Some people have symptoms that continue for months after infection. The World Health Organization describes post COVID-19 condition as symptoms that continue or start after infection and last at least two months, with no other diagnosis explaining them (WHO fact sheet on post COVID-19 condition). Appetite changes can be part of that mix, often tied to fatigue, smell changes, breathlessness, or stomach issues.

Craving Shifts And What They Can Point To

Cravings aren’t moral signals. They’re clues. They can point to sensory changes, hydration needs, low energy, or plain convenience. The trick is turning a craving into food that meets the need and still leaves you feeling okay.

Use this table as a pick-list. Try one or two rows for a few days, then adjust.

What you’re craving	What it might reflect	What to try next
Strong sweet foods	Low energy, low appetite for full meals	Pair sweet with protein: yogurt + fruit, peanut butter toast, milk with cereal
Strong salty snacks	Dry mouth, sweating, low intake	Broth soup, salted nuts with water, oral rehydration drink if diarrhea is present
Cold and creamy foods	Sore throat, nausea, smell aversions	Smoothie with Greek yogurt, chilled oatmeal, cottage cheese with fruit
Crunchy textures	Muted smell, need for sensory “feedback”	Whole grain toast, apples, roasted chickpeas, crunchy salad kits
Spicy foods	Searching for stronger flavor signals	Add heat in small steps; balance with cooling sides like yogurt or cucumber
Sour foods	Muted flavor, saliva stimulation	Citrus, pickled veggies, vinaigrette on bowls; rinse mouth after if reflux flares
Only bland carbs	Nausea, stomach sensitivity	Toast, rice, bananas, broth; then add eggs, tofu, or chicken in small portions
Nothing sounds good	Smell distortion, fatigue	Small meals on a timer, meal replacement drinks, simple soups, ask for medical advice if it persists

How To Eat When Smell Or Taste Is Off

You don’t need perfect meals while recovering. You need steady fuel, fluids, and enough protein for repair. These tactics lower friction.

Let texture and temperature lead

If flavor is flat, texture carries the experience. Mix crunchy and soft. Use hot and cold contrasts. Add color: berries, leafy greens, orange vegetables. Color can cue appetite even when smell lags.

Build meals from three parts

Pick a base, a protein, and a booster. Keep it simple.

• Base: rice, pasta, potatoes, oats, bread, tortillas.
• Protein: eggs, Greek yogurt, tofu, beans, fish, chicken.
• Booster: olive oil, cheese, avocado, nuts, salsa, herbs.

Use liquids when chewing feels like too much

When you can’t face meals, liquids can bridge the gap. Milk, kefir, drinkable yogurt, smoothies, or meal replacement drinks can carry calories and protein with less chewing and less odor. Keep servings small and frequent so you don’t trigger nausea.

How To Spot When A Craving Shift Needs Medical Care

Short-term swings during illness are common. Red flags show up when craving changes pair with poor intake, dehydration, fainting, or ongoing stomach symptoms.

What you notice	Why it matters	Next step
You can’t keep fluids down for 24 hours	Dehydration can build fast during fever or vomiting	Seek urgent care, especially with dizziness or dark urine
New chest pain or trouble breathing	Could signal a complication not tied to appetite	Seek emergency care
Food aversions last beyond a month and intake stays low	Low protein and low calories can slow recovery	Book a medical visit; ask about smell loss care and nutrition planning
Smell distortion makes many foods intolerable	Parosmia can shrink diet variety	Ask about ENT evaluation and structured smell training
Ongoing diarrhea, reflux, or nausea	Gut symptoms can keep cravings narrow	Get assessed to rule out infection, medication effects, or other causes
Fast weight loss or frequent faintness	Can signal poor intake or dehydration	Seek medical care soon

A Two-Minute Daily Log That Helps

If it feels like chaos, a short log can turn fog into patterns. Two minutes per day is enough.

• Smell and taste: normal, muted, distorted.
• Main cravings: sweet, salty, cold, crunchy, bland, none.
• Stomach status: fine, queasy, reflux, diarrhea.
• Energy: low, medium, high.
• What worked: one safe meal and one backup snack.

After a week, you’ll often see a pattern. On “distorted smell” days, cold foods may go down easier. On “low energy” days, sweet pulls may spike. Once you see that, you can plan around it instead of guessing.

What To Expect As Your Senses Return

Recovery can be uneven. Smell may return in bursts, stall, then jump again. Some people get a phase where certain foods smell harsh or rotten. Clinicians often call that parosmia. It can fade with time.

If cravings swing as your senses change, that’s not a step backward. It often means your brain is relearning food signals. Keep meals simple, keep protein steady, and keep trying small bites of foods you miss. Your safe list can grow.

Practical Takeaways

Cravings can change with COVID-19, often tied to smell and taste changes, nausea, fatigue, and routine shifts. Aim for steady fluids and protein, use texture and temperature to make food tolerable, and get medical care when intake stays low or warning symptoms show up.
