Recovering from an illness isn’t just about getting rid of an infection the body also needs to repair tissues, rebuild muscle, and gradually regain lost strength. This process becomes harder after a prolonged illness or hospital stay, especially when appetite has taken a hit.
So does eating enough protein actually help the body bounce back faster? According to medical experts, the answer is yes but with important nuances.
Why Protein Matters During Recovery
Protein provides the essential building blocks needed to repair tissues, maintain muscle strength, and support immune function. During illness, people often eat less while their body simultaneously breaks down more muscle particularly during prolonged infections or hospital stays. Getting adequate protein can help limit this muscle loss and support a faster return to normal strength and physical function.
That said, protein alone isn’t a magic fix. Recovery also depends on adequate calories, proper hydration, quality sleep, appropriate treatment, and gradually resuming physical activity.
Does Fever or Infection Increase Protein Needs?
Fever, infection, and inflammation can accelerate the breakdown of body proteins, especially in muscle tissue. At the same time, appetite often drops during illness, making it harder to replace these losses through regular meals. This mismatch can create a situation where the body loses muscle faster than it can rebuild it.
As a result, protein requirements may increase during certain illnesses though the exact amount depends on the severity and duration of the illness, along with a person’s overall health status.
Who Should Pay Closer Attention to Protein Intake?
Certain groups are more vulnerable to inadequate protein intake during recovery, including:
- Older adults
- People who have unintentionally lost weight or muscle mass
- Those with a poor appetite
- Individuals recovering from prolonged or serious illness
Older adults, in particular, tend to lose muscle more quickly during periods of inactivity or illness. Similarly, extended hospital stays or severe infections can lead to significant muscle loss and weakness, making adequate protein intake especially important though the right amount should always be personalized based on health status and any existing medical conditions.
How Much Protein Do You Actually Need?
There’s no universal protein target for everyone recovering from illness. For many healthy adults, a general reference point is around 0.8 grams of protein per kilogram of body weight per day. However, during illness, this requirement can rise older adults dealing with illness may need approximately 1.2 to 1.5 grams per kilogram per day, while those with severe illness or malnutrition may require different amounts under medical supervision.
Importantly, more protein isn’t automatically better for everyone particularly for people with kidney disease or certain other medical conditions.
Eating Well When Appetite Is Low
When appetite is poor, smaller and more frequent meals are often easier to manage than large portions. Good protein rich options include eggs, milk, curd, paneer, dal, beans, soy, fish, chicken, and other lean meats. Adding milk or yoghurt to smoothies or soft foods can also help boost protein intake without requiring larger meals.
For those following a vegetarian diet, combining dal, beans, soy, dairy, and grains can meaningfully improve overall protein intake. If eating remains a challenge, consulting a doctor or dietitian can help determine whether nutritional supplements are appropriate.
