What others are saying about Andrea....

My Sports Dietitian: Eat 2 Win

“Andrea Chapin helped me run my fastest marathon and qualify for the Boston marathon! She took into consideration what I was putting in my body daily and my training plan. She gave me double suggestions to help make a positive impact on my nutrition to support my body through long training runs. Before working with Andrea I was loosing 4-6% of my body weight during one 2 hour training run that usually ended in terrible stomach pains and a bloody nose. She helped me figure out a pre-run meal that was gentle on my stomach, how much water, electrolytes and carbohydrates to take in during my runs and a post-run meal that agreed with my stomach. I don’t know if I would have qualified for the Boston marathon without Andrea’s help. I highly recommend Andrea Chapin for anyone with athletic or lifestyle goals! ”

“Andrea taught me a lot about nutrition and how certain foods at certain times can help in muscle growth, recovery, and maintenance. She helped me with me meal ideas and times when I should be eating. Because of her, I was able to gain a lot of strength and muscle mass that I wasn’t gaining before because I wasn’t eating right. I’ve been playing sports and lifting for a very long time but I never gained the mass i wanted and Andrea gave me the knowledge I needed to achieve my weight goals. ”

“ Working with a sports nutritionist is key for an athlete. They help guide you to maximize your training. The hardest thing athletes do is understanding and figuring out how to fuel their body to maximize their efforts. Learning how to meal prep, when to eat, what to eat is a big component to getting max performance in the weight room and field. ”

“Hi, my name is Natalie Johnston I am 17 years old. I am a competitive swimmer and water polo player. I concentrate more on water polo because I really like it and it's just more fun. The practices are hard and at times intense. I was finding myself fatigued and it was taking me longer to recover. I was so hungry after practices and games I would eat burritos, pizza, cheese burgers and binge on fries and chips. My weight was never a problem, in fact I was thin, 5'8" 125lbs. I knew my diet needed help. My dad who is a therapist worked with Andrea at the hospital and he reached out for some advice. Andrea helped set up a diet and gave us ideas for healthy snacks and types of foods that would give me more energy. I have incorporated her plan into my diet. Not saying I don't still have Chipotle or in-n-out just not as often. ”
