It depends. Really, it depends on who you are and what you're trying to do. No absolute answer....except that refined sugars are almost never a good idea for anyone.

Well, I'm not a nutritionist or dietitian. But, in my head......if I'm in a caloric deficit, I wouldn't think it would matter. So, I'd go by taste (whichever was in front of me that looked like it tasted better).

I am no mechanic but if I am at the gas station and my tank is empty, I could put methanol, gasoline or diesel. So I would go by price, whichever was in front of me and was cheaper :-)

Good news is the body will take whatever you give it but that may not be what is ideal.

I would rather consume 100 calories from fat

This might be a better thread if you stated the purpose of the question? Why do you want to know about some arbitrary and unrealistic question with a dozen disclaimers?

From post 19 above, Dev says:
OK, in that case let's say you are going to consume 100 cals protein, 100 cals complex carbs and 100 cals of something else all at the same time. Those last 100 cals of something else, what you put in your salad or sandwich...where will they come from? Basically trying to get at whether you will trend your overall diet more to fat-centric than sugar-centric.

Personally, I shoot for a pretty even mix of fat and carbs with moderate protein, e.g. roughly 45% fat, 45% carbs, and 10% protein. I've found that my body shifts to burning mainly fat flawlessly when i get hungry IF my last meal had a fair amount of fat. If the last meal was mainly carbs and protein, then I will likely go hypoglycemic (with the shakes and sweating in extreme cases) before settling into the fat burning mode.

I'm just confused why protein isn't a choice, given that you're asking about macronutrients.

What spurred the question in the first place?

It's not that protein is not a choice. I am just assuming you are going to get your protein in over the day and just wondering for the non protein, how you prefer to break it down. Maybe I should have not focused on the 100 cal number and just said for your "non protein calories how do you prefer to break it down". I just went down to 100 because it was mainly an adder portion around a snack (do I add olive oil or butter to what is on my plate or do I add jam or honey). In any case, I am just assuming everyone is getting enough protein so for the non protein how athletes prefer to break it down and would like to see if our trends are any different from non athletes who I had discussion with about food breakdown. In theory athletes should need a higher proportion from carbs than non athletes. In practice, I don't think that non athlete trend to any less carbs than us.
