Dr Vijaya Venkat is one of her kind and has created a legacy through this center. One of the staff there tells me that she hasn't had water in last 8 years and is so healthy! Yes they are very radical. After the first visit to them you will surely be puzzled and everyone around you will try to tell you their theory can't be true! But once it sinks in, and you have followed their advice to the T, your body will see unforeseen changes and you will feel light & energetic! They give you a book too which has the rationale behind what they say. They explain to you why your body needs to go for repair and servicing and it can't be running at that time. they teach you ways of deactivation too! They literally hand hold you through the meal plan they advise - the closest to nature, least cooked food, no non veg and no dairy! In some cases, no cereals. But the most important is they tell you when to eat what! In the morning, body is cleansing itself so only fruits etc...Also the sequence of the food items! They also tell you to make your food tasty! Apart from obvious loss in weight in a short period of time, it has helped me regain my body's intuitive ability to tell when it's heating up or why I shouldn't eat something on a certain day. In fact for some others too! I am waiting for a miraculous correction that I went to them for. If you must ever go to any nutritionist, go to them!
