Here’s something to think about- from an evolutionary perspective people were eating fruits LOONNNGGGGG before they were eating either rice, oatmeal, or potatoes. Wouldn’t it make sense, then, that our bodies are more adapt at handling them? Quite a few fruits are specifically produced by plants to be eaten by other creatures. From a scientific perspective, you’d have to assume that many fruits have evolved to be eaten by animals and animals have developed better strategies for handling them over a longer period of time than many of the other current carb sources.
I think there’s more to the story than “they are just sugar”. It seems very weird to me that after hundreds of thousands of years of consumption, they are now reduced to a slightly elevated desert food.[/quote]
The context of this thread is physique/performance enhancement. Not evolutionary biology. [/quote]
And you don’t see how those things might be related?[/quote]
Related, but not dispositive of anything.
Your claims/arguments are a logical nightmare. Im not going to explain bit by bit why the things you say fail. [/quote]
Thinking that I was trying to make a claim based on evolutionary biology is where you’re going wrong. I’m not. What I’m asking is “Is there more to the story that fruits are on par with desert/table sugar for a body builder, based on our longer relationship with them?”. Asking a question doesn’t = making a claim. The truth is, based on your statements, you don’t know the whole story about fruits. I readily admit that I don’t either, which is why it would be wise for both of us to ask questions instead of assuming we know everything.[/quote]
I dont need to know the whole story about fruits to confidently say that fruits are not valuable to a person seeking physique/performance enhancement.
This isnt a ‘deep’ subject. And Im done with it. [/quote]
Ok.

There’s a misconception in the bodybuilding world that the fructose in fruit will hamper body fat loss. As Carter explains here, it is likely not a concern if you are not consuming truck loads of fruit a day.
The only time I can see completely eliminating fruit as beneficial would be for those who are already at an extremely low bodyfat, just weeks out from a physique contest (or following something like the GSD), and trying to get even more shredded. In this case, they have likely eliminated most of everything (carbs, fat, etc…)… so fruit is no exception.
Fruit is more carb dense than vegetables, so one has to factor in their carb content. Generally speaking, for those who are not carb tolerant, a 4:1 ratio of vegetables to fruits is best, with morning and during the post workout period as the optimal time for fruit consumption.

There are a couple assertions in there that make me want to call Phil and have him add a caution sign to the smiley list. Specifically, the notion that fructose only serves to replenish liver glycogen and that fruit is essentially being looked at only in terms of it’s fructose content.
But first things first, why are you carb cycling outside of the nutrient timing laid out by PN? Or am I reading into your approach incorrectly?
Back to the somewhat faulty (or at least too absolute sounding) assertions -
Fructose can and does replenish more than liver glycogen - it’s preferential “target” is the liver however. (read: it can replenish muscle glycogen it just takes a longer route and makes sure the liver is looked after. Which by the way, needs to be looked after if you are glycogen depleted - you can’t be depleted and then just “refill” your muscles. The liver needs to be filled too). Moreover, it’s been shown that fructose can potentiate glycogen synthesis when combined with other sugars (albeit this is questionable). And if that weren’t enough, it’s also been shown to have a glycogen sparing effect. Now of course the positives stop when we’re talking about artificially copious amounts (read: non fruit).
Take home point though - fructose is metabolized into glyceraldehyde and dihydroxyacetone phosphate and these can readily enter the the glycolytic pathway. From there, some dancing around occurs but some of the fructose will end up as glucose and glycogen. Eat too much and yes, the liver gets stuffed and you get fat because of the propensity for a lipogenic effect. But that’s why you’re avoiding high-fructose corn-syrup. If you’re not consuming high fructose corn syrup or 1000g+ of fruit per day, you’re not triggering this propensity for lipogenesis. Or rather, it wouldn’t be the fruit intake that’s triggering it. Which brings me to my next point.
Fruit isn’t just fructose. Clearly there’s a huge upside in the phyto and micro nutrient departments - an upside people far too often downplay because they’re fixated on the often inconsequential finite details of caloric composition. But additionally, the carb content isn’t entirely, or with some fruits, even primarily fructose. And I’m not just talking about the fiber found in fruits. I’m talking specifically about the fact that many fruits have an appreciable amount (% wise) of other sugars. Primarily glucose.
And let’s not forget that per 100g of fruit, generally speaking we’re looking at 10g or less of total sugar content with fructose making up 33-66% (so 3-6g). That’s not a lot. Especially when one is looking to load glycogen.
So to answer your question, a combo of fruit and starchy carb sources is your best approach. But how much and when will depend on whether you’re following proper nutrient timing while doing this carb cycling or whether it’s some non-optimized carb intake system (meaning carbs all day).
