    The average American gets only about 10 to 15 grams of fiber a day, which is less than half the recommended 25 grams for women and 38 grams for men.
    Most of us don’t realize we’re falling short until digestion starts to feel off: bloating, constipation, sluggishness, and that uncomfortable “never quite right” feeling. If you’re on a GLP-1 medication, low fiber intake can matter even more, since constipation is one of the most common and frustrating side effects.
    So how do we close the gap without overhauling everything we eat?
    In this episode, I walk you through simple, realistic ways to build more fiber into your day. I’m sharing the foods and products I personally rely on, what to know about magnesium and probiotics, and how to spot supplements that may be helping your digestion or working against it.

    As women, so much of our identity is tied to our hair. And when it starts to fall out, the internet will sell you a thousand solutions before anyone stops to ask why.
    In this episode, I'm joined by Dr. Komal Patil-Sisodia — triple board-certified endocrinologist, hormone expert, and someone who has lived this firsthand. Stress-related shedding in med school. Postpartum loss. Genetic thinning. She's been through every stage, and she's here to help you finally get some answers. 
    We get into the real hormonal and metabolic causes, the labs worth asking for, and why addressing the root cause will always matter more than the next serum, supplement, or device in your feed.

    What if you've actually been making progress, but just didn't know how to see it?
    So many people feel stuck because the scale isn't moving, or because progress feels painfully slow. But total weight is only one piece of the picture. You could be losing body fat, building muscle, and moving in exactly the right direction… without even realizing it.
    In this episode, we look at how to use body composition data in a practical way, which numbers matter most, and how to avoid letting the data take over your life.

    After pouring everything into my recent in-person retreat, coming home felt harder than I expected. I was sleeping in on weekends, struggling with my normal routine, and asking myself, "Why can't I just get it together?"

    “Doc, I just don't feel like drinking alcohol anymore." 
    Addiction psychiatrist Dr. Nishant Kumar kept hearing it. Patient after patient, unprompted. And nothing in their lives had changed… except one thing. They'd started a GLP-1. 
    What does that tell us about the brain, addiction, and our relationship with food?
    In this episode, Dr. Kumar unpacks exactly that. We talk about what GLP-1s are revealing about cravings and the brain, how to recognize when your relationship with food has become a problem, how to find the right help, and the lifestyle factors that matter more than you might expect.
