An interesting question is whether there is any advantage in eating the macronutrients — fat, carbs, protein — in any sequence?
There is a lot of evidence that having fat in one’s meal aids the digestion of various vitamins and minerals. Without the presence of fat, these nutrients are digested, but not as well as they would have been had there been some fat available.
Fat also has no impact at all on insulin, and if you eat a meal that includes some fat, the carbs, which will spike insulin, will spike it much less severely because of the presence of fat. You do want to lower insulin spikes as much as possible.
There is also a good deal of evidence that protein is very satiating, and also slows down digestion because the protein compounds require a lot of work by digestive enzymes to break them down, which is a good thing.
So on balance, eating fat/protein at the start of a meal would appear to be the best strategy, and nothing fills that bill better than a handful of mixed nuts — high in both fat and protein. Perhaps you should start all your major meals with a source of fat/protein like nuts to improve your digestion.
