When you have COVID-19, your body needs more calories and protein than usual to fight the virus and prevent muscle loss, but your appetite, taste, and energy for cooking are probably at their lowest. The priority is staying hydrated, eating enough protein to support your immune system, and choosing foods that work with your symptoms rather than against them.
Hydration Comes First
Fever, sweating, and breathing through your mouth all pull water from your body faster than normal. Aim for at least 64 to 70 ounces of water daily, which is roughly eight to nine cups. If you’re running a fever or sweating heavily, you’re also losing electrolytes like sodium and potassium. A half-and-half mixture of water and a sports drink can help replace what’s lost without overloading on sugar.
Avoid alcohol entirely and limit caffeinated drinks, which can worsen dehydration. Be especially cautious with anything marketed as an “energy drink,” as these tend to contain high amounts of caffeine even when they promote hydration. Warm broth counts toward your fluid intake and doubles as an easy source of sodium and calories when eating feels like too much effort.
Protein Protects Your Muscles
Your body breaks down muscle tissue faster during any significant illness, and COVID is no exception. Expert consensus supports consuming 1.2 to 1.5 grams of protein per kilogram of body weight per day during acute illness to counteract this breakdown. For a 150-pound person, that works out to roughly 80 to 100 grams of protein daily.
That number sounds high when you have no appetite, so lean on foods that pack protein into small portions: eggs, Greek yogurt, nuts, canned fish, or pre-cooked chicken. A cup of Greek yogurt alone delivers around 15 to 20 grams. Protein shakes or smoothies made with milk and nut butter can help you hit your target without requiring you to sit through a full meal.
Foods That Match Your Symptoms
Sore Throat
Warm (not hot) broths and soups coat and hydrate the throat. Soft foods like bananas, oatmeal, and yogurt go down without irritation. Popsicles can numb throat pain and provide some fluid at the same time. Avoid crunchy, acidic, or spicy foods that scratch or sting inflamed tissue.
Nausea or Diarrhea
Stick with bland, low-fiber foods like plain rice, toast, applesauce, and bananas until your gut settles. Eat small amounts frequently rather than forcing full meals. Research shows that probiotics, found in yogurt and fermented foods like kefir, can shorten the duration of COVID-related diarrhea. If you’re losing fluids through vomiting or diarrhea, electrolyte replacement becomes even more important.
Loss of Taste or Smell
This is one of the most frustrating symptoms because it can make eating feel pointless or even unpleasant. Cold and room-temperature foods tend to work better than hot foods, because heat releases more volatile compounds that can trigger distorted smell sensations. Cold chicken slices, for instance, are often tolerable when roasted chicken is not.
When you can’t taste much, lean into texture. Combine crunchy, soft, and creamy elements in the same meal to keep eating interesting. Bright colors on the plate also help stimulate appetite when flavor can’t do the job. Focus on nutrient density so that even small amounts of food deliver what your body needs.
Anti-Inflammatory Foods for Recovery
COVID triggers significant inflammation throughout the body, and what you eat can either dial that up or down. A dietary pattern heavy in fruits, vegetables, legumes, olive oil, and fish is linked to lower levels of inflammatory markers and, in large population studies, fewer COVID infections and less severe illness.
Fatty fish like salmon and sardines are rich in omega-3 fatty acids, which reduce inflammation by lowering C-reactive protein and blocking the production of inflammatory signaling molecules. If fish isn’t appealing while you’re sick, walnuts and chia seeds offer a plant-based alternative. Colorful fruits and vegetables provide polyphenols, compounds with antioxidant and anti-inflammatory properties. Berries, leafy greens, sweet potatoes, and citrus fruits are all good choices.
Zinc plays a critical role in immune cell development, and being deficient in it increases oxidative stress and inflammatory responses. You can get zinc from nuts, seeds, legumes, and eggs without needing a supplement.
Easy Foods When You’re Exhausted
Fatigue is one of the most common and persistent COVID symptoms, and cooking a full meal may be unrealistic. Focus on foods that require zero or minimal preparation:
- No prep: Bananas, oranges, nuts, seeds, yogurt, cheese, canned fish, nut butter on bread
- Minimal prep: Oatmeal, eggs (scrambled in 3 minutes), canned soup or broth, frozen vegetables microwaved with pre-cooked rice
- Batch-friendly: A pot of lentil soup or bean stew made once can last several days and provides protein, complex carbs, and fiber in every serving
Complex carbohydrates like oatmeal, sweet potatoes, whole-grain bread, and brown rice provide sustained energy without the crash that comes from sugary snacks. Pair them with a protein source to slow digestion and keep your blood sugar stable.
What About Supplements?
Despite widespread interest in vitamin C, vitamin D, and zinc supplements for COVID, the NIH COVID-19 Treatment Guidelines Panel found insufficient evidence to recommend any of them for treating COVID in non-hospitalized patients. The panel specifically advises against taking zinc above the recommended daily allowance for prevention purposes.
This doesn’t mean these nutrients are unimportant. It means the evidence doesn’t support megadosing through supplements. Getting vitamin C from citrus fruits and bell peppers, vitamin D from fortified dairy or sunlight, and zinc from whole foods gives you these nutrients in the context of a balanced diet, alongside the fiber, polyphenols, and other compounds that supplements can’t replicate.
A Practical Daily Template
You don’t need a rigid plan, but a loose framework can help when brain fog and fatigue make decisions harder. Spread your eating across five or six small meals rather than three large ones, especially if nausea or low appetite is an issue.
A realistic day might look like: oatmeal with berries and a spoonful of nut butter in the morning, yogurt with seeds mid-morning, soup with canned fish or leftover chicken at lunch, a banana with a handful of almonds in the afternoon, and scrambled eggs with toast and avocado for dinner. Sip water, broth, or diluted sports drinks throughout the day. This pattern delivers protein at every meal, covers your major vitamins and minerals, and doesn’t require much time on your feet.
