I have practiced a modified form of warrior diet for months without knowing it.

This regime has a name but not enough research or scientific endorsement. I think for some people Warrior Diet works because of calorie accounting + nutritional quality. See https://www.healthline.com/nutrition/6-ways-to-do-intermittent-fasting. Key points

• eat raw veg + fruits during the day
• instead of a huge meal, I eat a controlled meal at night.
