I saw this article and thought it was relevant. With Soylent you would be getting an even distribution of protein through out the day.
This research shows that the typical cereal or carbohydrate-dominated breakfast, a sandwich or salad at lunch and overly large serving of meat/protein for dinner may not provide the best metabolic environment to promote healthy aging and maintenance of muscle size and strength.
The new study, now online in press in the Journal of Nutrition, shows that the potential for muscle growth is less than optimal when protein consumption is skewed toward the evening meal instead of being evenly distributed throughout the day.
When study volunteers consumed the evenly distributed protein meals, their 24-hour muscle protein synthesis was 25 percent greater than subjects who ate according to the skewed protein distribution pattern.
Do this, and over the course of the day you will likely spend much more time synthesizing muscle protein.
