Bariatric Surgery Changes Your Anatomy. What Comes Next?

Protein first. Sip your water. Take your vitamins.

If you’ve had bariatric surgery—or you’re preparing for it—you’ve probably heard these instructions more than once. But knowing the rules and understanding how to live with them are two different things.

Why does protein matter so much? How do you fit fluids into your day? And what happens when the routine gets harder to follow?

Understanding the “why” helps you make sense of the everyday decisions.

That’s why I created Learning the Rudog Way, a practical guide to bariatric nutrition before and after surgery. It brings together clear explanations, helpful visuals, and guidance you can return to as questions come up.

Whether you’re getting ready for surgery, finding your rhythm afterward, or revisiting the basics years later, you don’t have to remember everything at once.

After more than 30 years as a registered dietitian, I know that nutrition information is most useful when you can apply it to real life. That’s the idea behind every page.

Learning the Rudog Way is available as a downloadable guide for $12.95.
