What to eat,
When to eat,
How to eat

I’ve struggled with this as I get very busy during the day, skipping meals, grabbing a not-so-healthy snack in a pinch. Sarah helped me get through it without the nonsense of fad dieting. Sarah really listens and talks through my time challenges to come up with workable solutions. She’s friendly, sympathetic, and genuinely cares about getting you through your hurdles. She’s also honest, down-to-earth and doesn’t just throw information at you. We’ve gone through not only what to eat, but also strategies on how to tackle my schedule. She gives you real examples applicable to your life and schedule of how to apply the strategies throughout the day. I’ve been seeing results and highly recommend Sarah to anyone looking for a true change in their eating habits and lifestyle.”
