Note that the whole idea is about taking very small amount of sugar at the right time. It's completely unrelated to levels that cause metabolic syndrome.
33:33:33 seems to arise fairly naturally when I try to eat reasonably limited amounts (for purely cosmetic temporary reasons; and all unrelated to the entire willpower business) of the tastiest food (most of which hits diminishing returns very quickly).
Here's some data on what people eat based on spreadsheetscripting out FAO data. As you can my current protein intake is indeed highly unusual - but then so are your very high fat and extremely low carb intake. Pretending what you're doing is the norm when it's really out of the norm is weird.
33:33:33 is similar to what is recommended for zone diet and paleo diet, so I cannot be the only person doing that. Similarity to zone diet purely accidental. Similarity of my constrained optimization for best taste with paleo diet is quite likely not accidental at all.
Your calorie intake is slightly high for the zone diet. That could be fine. The typical version of the zone diet is meant for weight loss and you need a higher amount of calories to maintain weight. The zone recommendation is to get those extra calories from healthy fats. The zone diet is also very concerned with maintaining the correct ratio for every meal and snack, not just as a long term running average. This makes sense if the goal is controlling insulin spikes after each meal.
I agree with Kutta that your protein consumption is much higher than is necessary. I am less clear on what the health consequences of that are.
There's considerable amount of evidence that willpower is severely diminished if blood glucose get down, and this effect is not limited to humans. And a small sugary drink at the right time is enough to restore it.
We're talking really small numbers. Total blood glucose of a healthy adult is about 5g and it varies within fairly limited range. Then there's maybe 45g in total body waters. Then there's about 100g of glycogen in liver, plus yet larger amount in muscles and other organs, but which doesn't seem to take part in sugar level regulation. For comparison a small can of coke contains 33g - a really small amounts at appropriate times can make a big difference.
This leads to two issues. First, is blood glucose a good explanation for willpower deficiency and therefore akrasia? I'd say there's significant amount of evidence that some effect exists, but is it really the most important factor? Humans are complicated, science knows very little about how we work, and probably half of what it "knows" is false or at best only half-true. Caution is definitely warranted.
And the second issue - if this theory was true - and by manipulating blood glucose levels you could achieve far greater willpower whenever you wanted, what would you do? It seems that exploiting it isn't that easy, and I'd love to hear if any of you tried it before.
