Soylent was originally touted as a meal replacement but I (and others) have found that it works best as a "plan B" to nutrition. It changes the way you look at food if you always have an option to just get the nutrition you need quickly and easily: a lot of meals you'd normally skip you don't, and a lot of meals you eat that are less than nutritious you can either opt-out of or can supplement with proper nutrition wi…
Where Soylent falls short in this respect is that it's nutrition is only ideal given that the rest of your diet is Soylent too. It has a ton of carbs, and if you're anything like most Americans, you already have way too many carbs in your diet. Unless you're doing a lot of physical activity and you need those carbs, most people would do better just drinking a regular whey protein shake.
[I know there are things like Keto fuel, but these all require buying a bunch of oil and stuff and mixing it in, which is not the seamless solution I really want.]
