If you’ve ever tried to tweak your diet—whether to lose weight, build muscle, or just feel healthier—you’ve probably heard lots of opinions on protein. Some people say you need a lot, others say a little goes a long way, and then there’s all the conflicting advice about plant-based vs. animal-based protein. So, how do you know how much protein you really need to fuel your body properly?

On this episode of the Healthier You podcast, Dr. Ashlee Williams speaks with Dr. Christie Youssef, a family medicine physician at Kaiser Permanente, about how protein works in your body, how much you need depending on your goals and lifestyle, and why it’s not a one-size-fits-all answer.
