It is a 5-star philosophy for mental health, but a 2-star plan for rapid physical transformation. Combine her rules (eat local, no screens, ghee) with a basic calorie deficit, and you will win. Follow her plan blindly without exercise and portion awareness, and you will simply become a "well-fed fat person."
Her plan hinges on the idea that our grandmothers knew best. However, our grandmothers walked 10km a day, churned butter by hand, and slept on time. Her advice (e.g., "eat jaggery instead of sugar") is good, but jaggery is still sugar. Nostalgia does not change biochemistry.
She correctly attacks the obsession with Protein Shakes, "Sugar-Free," and "Fat-Free" products. She argues (correctly) that removing fat from curd adds sugar and chemicals. This is evidence-based nutrition.
