My experience
Simple enough to repeat. Enjoyable enough to keep.
I chose a breakfast and lunch I genuinely liked, calculated their protein and calories once, and made them my defaults. Together they usually gave me about 80–85 grams of protein before dinner. Dinner could stay flexible, and days out did not need to be perfect.
I have eaten my egg-white breakfast for seven months. It does not feel boring because it tastes good to me and removes a decision from a busy morning. I paired this approach with three familiar strength workouts each week—Push, Pull and Legs—and tried to add a controlled rep or a little weight over time.
This routine helped me lose more than 30 pounds after each of my two pregnancies. That is my experience, not a promise that another person will have the same outcome. Bodies, recoveries, health conditions, resources and goals differ.
