This question is named analogous to this research: How much protein can the body use in a single meal for muscle-building? Implications for daily protein distribution http://ncbi.nlm.nih.gov/pmc/articles/PMC5828430
How many grams of lipids can the body absorb in one sitting? (I ask because a strict vegetarian or vegan diet is characteristically low in fat. Therefore, I consume extra virgin olive oil and nuts.)
Most of the research on pubmed.gov is about oral lipid drug administration/absorption. This work that seemed to come close is over my head and just doesn't seem to specify:
