As a joint replacement surgeon, one of the most common questions I hear is: “What can I do before surgery to make my recovery smoother?” The good news is that there is a lot you can do—long before you arrive in the operating room—to support your healing, strengthen your body, and improve your overall well-being.
Think of this period as preparing the soil before planting a garden. The healthier the foundation, the better the outcome.
Below are evidence-informed, practical steps you can take to support your body before surgery. These are general principles—not personalized medical advice—and your own healthcare team can help tailor recommendations to your individual needs.
After joint replacement, your body is busy rebuilding and repairing soft tissues to restore strength. Eating well before surgery gives your body the raw materials it needs for that work.
Healthy sources of protein and fiber are especially important. Protein supports tissue repair, and fiber helps maintain gut health, stabilize blood sugar, and prevent constipation—something many patients struggle with after surgery.
You may have heard the phrase "food is medicine." While not every food acts like a medication, certain eating patterns can have powerful effects on metabolism, inflammation, and long-term health. For example:
Change can feel overwhelming, but remember: every meal is an opportunity to help your body heal.
If you want individualized guidance, a registered dietitian can help you choose foods and patterns of eating that align with your goals—whether that’s weight loss, longevity, or simply eating more intentionally.
While everyone’s needs differ, research suggests that during rehabilitation, many people benefit from:
These are general ranges from published research—not personalized targets—and your healthcare team can help you understand what’s appropriate for you.
There is no single “joint replacement diet.” In fact, I don’t love the word diet at all—it implies something temporary. What we’re really talking about is adopting a sustainable lifestyle that supports your health.
Here are several evidence-supported eating patterns that can be adapted to your needs:
This approach goes beyond simply “low-carb.” It focuses on quality, timing, and preparation — helping you choose carbohydrates that support stable blood sugar and metabolic health.
Across all these patterns, the themes are the same: whole foods, high-protein, high-fiber, healthy fats, and minimizing highly processed foods.
A nutritionist can help you determine which approach fits your health profile and preferences.
Not everyone needs or wants to lose weight before surgery, but if it’s part of your goals, here are helpful principles:
Sharing a drink is part of many social and cultural traditions, and it’s understandable that alcohol may not be completely avoidable. That said, if your goal is long-term health and getting the most longevity out of your joint replacement, minimizing alcohol is one of the most meaningful choices you can make. Alcohol disrupts deep, restorative sleep, increases inflammation, interferes with muscle maintenance, and raises blood sugar by altering liver metabolism. It also provides calories without nutrients and is classified as a Group 1 carcinogen and there is no truly safe level of consumption from a cancer risk standpoint.
If you choose to drink, save it for special occasions rather than making it a daily or weekly part of your diet. Limiting alcohol supports better sleep, stronger muscles, and a healthier, longer-lasting outcome.
Alcohol:
Reducing added sugar is one of the simplest and most powerful steps you can take to improve your health before surgery. It’s not about eliminating joy from eating — it’s about being intentional and understanding where sugar hides.
Dessert every now and then is perfectly normal and enjoyable. In fact, a small amount of sugar paired with a high-protein meal or high-fiber snack can fit into a healthy diet. The American Heart Association recommends keeping added sugar below 25–36 grams per day, yet the average American consumes more than twice that amount (How Much Sugar Is Too Much? | American Heart Association).
The real challenge isn’t the occasional dessert — it’s the hidden sugars in everyday foods. Many packaged items contain added sugars even when they don’t taste sweet. Common culprits include:
When reading labels, check the first three ingredients. If any form of sugar appears there, consider that food a dessert in disguise. Added sugars can masquerade under many names, such as dextrose, glucose, fructose, maltose, sucrose, brown rice syrup, corn syrup, malt syrup, or evaporated cane juice.
Also be mindful of “free sugars” — like fruit juices — which can spike blood sugar just as much as soda. Whole fruits, on the other hand, contain fiber that slows absorption and supports gut health.
By cutting back on added sugars and focusing on whole, minimally processed foods, you’ll help stabilize blood glucose, reduce inflammation, and give your body a stronger foundation for healing.
Muscle mass is one of your greatest assets going into joint replacement. Movement is medicine! So keep moving in whatever ways feel safe for you. Maintaining strong muscles supports better joint function, improves overall bone quality, and helps protect you from fractures during daily activities or falls.
Small, consistent steps matter.
Sleep is one of the most underrated tools for healing. If sleep is difficult before surgery, it may remain challenging afterward, so establishing good habits now can help.
General strategies many people find helpful include:
While supplements can play a role in a healthy lifestyle, some may interfere with your recovery after surgery. Certain supplements can increase bleeding risk, interact with anesthesia, or affect wound healing.
A few supplements to discontinue perioperatively include, but are not limited to:
Always discuss any supplements or medications with your surgical team before your procedure to ensure a safe recovery.
Preparing for joint replacement is not just about the day of surgery—it’s about supporting your whole body in the weeks and months beforehand. Nutrition, movement, sleep, and lifestyle choices all play a role in how you feel going into surgery and how you recover afterward.
Every positive change you make now is an investment in your future mobility, comfort, and independence. Even small lifestyle adjustments before surgery can create meaningful momentum — and maintaining those habits afterward helps protect your new joint and supports long-term health.
