L-Nutra's the company. I assume you're talking about their product CHEMOLIEVE? They're not saying anything about it, trying to hide it under the umbrella of "proprietary". Presumably low carb to encourage ketosis. Probably a lot of MCT's. The pictures look like a shake of some type, so low carb, low protein, high MCT or coconut oil. Probably tastes disgusting.

Same as the ketogenic "fasts", probably just 10x the price of rolling your own (at a guess).
