Sports Nutritionist San Diego | Sports Nutrition Coaching

Performance Training Center delivers evidence-based sports nutrition coaching in San Diego, led by a Certified Nutritionist with 22+ years guiding competitive athletes, executives, and everyday clients to measurable performance and body-composition results. We don’t hand out generic meal plans — we engineer a fueling strategy around your physiology, your sport, and your numbers.

What a Sports Nutritionist Actually Does

A sports nutritionist translates your training goals into a precise, individualized fueling plan. The joint position of the Academy of Nutrition and Dietetics, Dietitians of Canada, and the American College of Sports Medicine establishes that nutrition must be periodized to training demands (Thomas, Erdman & Burke, J Acad Nutr Diet, 2016). Meta-analytic evidence shows protein intakes around 1.6 g/kg/day maximize resistance-training adaptations (Morton et al., Br J Sports Med, 2018), and the ISSN position stand details how protein dose, timing, and quality drive recovery (Jäger et al., J Int Soc Sports Nutr, 2017).

You Are What You Absorb

Eating protein is only half the equation — your body has to break it down to use it

Protein you eat

Meat, eggs, shakes, legumes

Stomach acid + pepsin

Break protein into smaller pieces

Amino acids absorbed

The usable building blocks

Muscle & recovery

Where your results come from

The catch: stomach acid activates the enzymes that digest protein — and acid output naturally tends to decline with age and stress. When digestion is under-powered, some of the protein you eat passes through under-used. That’s why we look at how well you absorb, not just how much you eat.

Absorption Self-Assessment

Could digestion be limiting your results?

I eat plenty of protein but don’t see the muscle or recovery I’d expect I often feel bloated, heavy, or overly full after protein-rich meals I’m over 40 I’m frequently under significant stress My energy dips notably after meals

Educational only, not medical advice. Do not start digestive supplements such as betaine HCl without guidance — they are not appropriate for everyone, especially if you take acid-reducing medication or have a stomach condition. Check with your provider.
