Gastric Bypass Cookbook is a cookbook for the bypass: the operation that makes a small pouch of the stomach and connects it straight to the small intestine. After it, portions shrink and some foods stop agreeing with you, so this book explains what changed, maps the stages of recovery and gives you simple, protein-first recipes for each of them.

Above all, this is the book for anyone weighing the bypass, or in the first months after it, who wants meals that are realistic rather than clever. In particular, you want clear guidance on each stage and recipes that are gentle on digestion. Megan Rush keeps both simple, stage by stage.

What is inside

• The bypass explained. What the surgery does to the stomach and the intestine, what that means for eating and how to make the change work for you.
• Your relationship with food. How to deal with cravings and build a balanced way of eating that lasts.
• An 8-week meal plan. Menus for the stages before and after surgery, so recovery follows a plan.
• The 5-day pouch reset. A short technique to get back on track when weight stalls or old habits return.
• Recipes for every stage. Simple dishes focused on protein and balanced nutrition, from meals for one to dishes to share.
• Three bonuses. A QR code inside the book unlocks Bariatric Success Stories, Bariatric Shopping Lists and a Mindful Eating Guide.

Between them, these parts follow one thread: eat for the pouch you have now. As a result, the book is most useful in the adjustment period, when every meal is a question.

How the recipes are presented

First of all, the recipes are broken down by stage, and each one keeps to a few ordinary ingredients and a few clear steps. Portions are drawn for a post-surgery stomach, and the focus is on protein first, so you meet your protein targets meal after meal.

Moreover, the dishes are deliberately plain. That is a choice: in the months after a bypass, gentle and predictable beats elaborate, and the book is honest about it. Finally, the medical chapters come first and stay short, so you reach the recipes quickly.

What readers say

Three verified purchasers, two in the United States and one in Britain, all five stars:

As someone navigating life after gastric bypass, I found the recipes and guidance practical and easy to follow. The portions and ingredient choices feel realistic for post-surgery needs rather than overly complicated or unrealistic. […] I’ve tried several recipes so far, and they’ve been easy to prepare and gentle on digestion.
