Biggest clue to ideal balance is in your mouth. Teeth small canines meaning little need for tearing meat, so this should be the lowest part, flattish teath at the back but not real big grinders set up for lots of highly fibrous foods, more set for higher quality roots, seeds etc. Saliva incredibly high in amylase, the enzyme responsible for breaking down starch to glucose, the biggest and most ignored clue that we are designed for a diet high in complex carbohydrate to such an extent we start working on it as chewing.
Seperating is a good way of avoiding you gettign to hungry by always having food in your stomach, but this could be done without by having smaller meals, it really makes no difference. It aslo will not cause harm so by all means try it.
Balance is something the western world gets so far off that it's insane. We eat far too much fat, protein, salt and of course sugar, meaning the very thing we have evolved for which is high starch diet has been turned on it's head. Because people don't seem to identify the difference between high sugar diet and high carb diet the low carb diet is promoted as the way to go.
When it comes to treatment of injuries etc. I always bow down to Jrahiens greater knowledge. Today it's nutrition and that is my arena, having studied it from perspective of sports, evolution, anatomy and many other directions I have learned how insanely we eat and how simple getting it right should be and isn't. All this and I still get it wrong.
There are very few ways in which food affects metabolism as it enters the body, but intake of carbs is the main one. We are designed to get most of our energy from carbs so the body judges what is coming in by how much carbohydrate we take in simple or complex. Drastically reducing this tells the body we have hit lean times and the metabolism is dropped to keep us alive, we feel the need to seek sweet food when this happens.
Excess carbs become fat, as much as it can excess protein becomes fat, and excess fat doesn't need to be converted. Carbs are the first energy source to be used so it is the easiest to avoid going to store. Eating too much makes you more likely to get fat, which type of energy is less important in this case.
Excessive intake of simple carbs aka sugars is dangerous in many ways and I strongly urge you not to do this ever. It is a great way to gain a lot of weight by totally messing with your insulin curve, driving up your apettite up and forcing your body to store a barely controlable influx of energy as fat.
Complex carbs aka starch are slow release and if eaten in small quantities throughout the day will keep you metabolism up, energy levels high and with a good training program avoid more than a minimal amount being stored as fat with more being stored using glycogen.
The high protein diet has been used to death because the Joe Weider clones have been promoting it on the basis that muscle is made of protein. For one thing muscle is 3/4 water, for another you will need more protein if you are training but this will be proportionate to the amount of extra energy you need to fuel training, recovery and new muscle tissue, so supplementing or increasing protein out of proportion will not help. The excess that cannot be converted to fat will be dispose dof the same was as excess water, in the urine.
