The (in my opinion) authoritative source [Institute of Medicine] recommends this for macros [1]: Carbohydrates: 45-65% Fats: 20-35% Proteins: 10-35% I don't think these macros are wildly unhealthy. Bodybuilders may require more protein. As you can see, 20% fat in the diet would definitely be at the lower end of the spectrum, while the current 43% is more than the upper range given. However, the IOM recommendations assume you are eating fats in the typical diet; there are very few unhealthy fats in Soylent–my (non-evidence-based) opinion is that it's o.k. I would definitely prefer healthy fats to carbohydrates for a number of reasons. 1. https://www.iom.edu/Reports/2002/Dietary-Reference-Intakes-for-Energy-Carbohydrate-Fiber-Fat-Fatty-Acids-Cholesterol-Protein-and-Amino-Acids.aspx https://www.iom.edu/Reports/2002/Dietary-Reference-Intakes-f...
