Sports & Exercise Nutrition FAQs
Q1
Should I work with a sports dietitian even if I’m not a professional athlete?
Absolutely! Sports nutrition isn’t just for elite or professional athletes. Many clients work with a sports dietitian because they want structure, guidance, and accountability as they are starting a wellness journey.
For example, someone looking to make a lifestyle change, improve energy, lose weight, build muscle, or feel more confident in the gym can benefit greatly from personalized nutrition support. A sports dietitian helps you fuel your body properly, build sustainable habits, and align nutrition with your activity level—no matter your starting point.
Q2
Can sports nutrition improve recovery and prevent injury?
Yes. Proper nutrition plays a key role in recovery, injury prevention, and long-term performance. Adequate energy intake, protein, carbohydrates, hydration, and micronutrients help support muscle repair, reduce fatigue, and maintain bone and connective tissue health.
When fueling is mismatched to training demands, the risk of fatigue, poor recovery, and injury increases. Nutrition helps ensure your body has what it needs to exercise consistently and recover effectively.
Q3
Is sports nutrition only about supplements?
No. Supplements are only a small part of sports nutrition - and often not needed at all. The foundation is always food-first: balanced meals, adequate energy intake, proper timing, and hydration.
If supplements are considered, they are used strategically, based on evidence, individual needs, and safety, never as a replacement for solid nutrition habits.
Q4
How often should I meet with a dietitian?
How often you meet with a dietitian depends on your goals, lifestyle, and the level of support you’re looking for. Many people start with an initial assessment, followed by regular follow-ups every 2–4 weeks to build momentum, adjust strategies, and stay accountable.
This frequency allows enough time to apply changes while still receiving guidance, feedback, and support. As confidence and consistency grow, sessions can be spaced out, with ongoing support tailored to your needs and goals.
