Why does one meal a day work at first—then suddenly stall?

Episode #249
🎙️ In this week's episode, Megan Ramos breaks down the pros and pitfalls of one-meal-a-day fasting (OMAD).

While OMAD can produce quick early results, it often plateaus for people with insulin resistance. Megan explains why daily OMAD can shift the body into chronic calorie restriction instead of true physiological fasting—and why that distinction matters.

She also shares practical strategies for using OMAD more effectively, including how variation in fasting schedules can help preserve metabolic rate, trigger a true fasting response, and break through stubborn plateaus.

👉 What you'll learn:
• Why OMAD often works at first but then stops working
• The difference between calorie restriction and true physiological fasting
• How the body adapts to the same fasting pattern every day
• Why insulin resistance changes how OMAD affects results
• How metabolic rate can slow during chronic calorie restriction
• A smarter way to structure OMAD using fasting variation
