    Yes, and you'll be ok with a couple portions of fruit a day. I don't recommend you leaving fruit out.

    The thing with fructose is that it is mainly used to replenish liver glycogen if it is depleted.. which can only hold so much. So when there is 'extra' fructose, it would be stored as fat.. Fructose isn't stored in muscle glycogen.. It can basically be used once it has 'passed through' the liver and converted.
    The liver is a good adapter... so it doesn't solely depend on fructose for replenishment.. it can use other sources to replenish itself.. like glucose for example.

    you should never omit fruit and veg in an attempt to remove cals from diet. Fruit and veg are very filling for their cals so are a real benefit in reducing cravings.

    Are you 100% certain that a sedentary person eating loads of bananas, pineapples, sultanas & raisins (and getting their EFAs & EAAs) could never get fat?

    lol - do they exist!!

    I'm with nige on the overconsumption aspect, but day to day, most folk eating apples and the like will be ok. That said I ate a bag of 20 apples stood in a cue one time - admittedly a 4hr cue, but none the less, a whole load of apples...

    I actually did that for a while a long time ago. I only had fruit, dried fruit, and nuts. I believe the 'diet' went something like.. as much fruit as you want all day (bananas too).. then in the afternoon dried fruit was allowed, and then later on in the evening the nuts were allowed.

    I went through quite a bit of fruit in the day. Thing is you get 'full' rather easily after a few portions. I also lost weight on that extremist way of eating! I followed that for maybe three weeks until I got fed up (I like meat and cheese too much lol).. And I only did one half hour cardio session in the morning before breakfast 3x/week..

    I also don't recommend this to anyone - I hadn't even found MT at that point

    It would have been a shame if, just as you reached the front of the queue, you had to dash off to the loo!

    Did you lose any muscle on that diet?

    I was only a little one then.. I only knew about weight and that I could weigh myself on the scales. And I think the site I used was FitDay to count my calories. By then I already knew how many calories was in everything anyways lol.

    I do tend to easily hold whatever muscle I do have though (not much I suppose lol). All I know is that I surely didn't get fatter, and I did look better - not as soft.

    I did keep food logs, and my calorie intake was higher than the 'diet' I was on beforehand..

    lol - I hadn't thought that at the time, luckily I didn't!! If I'm ever in the same situation again, I'm going to do the same, but bring a few cold stellas along for the wait too...

    In answer to your direct question, no I am not 100% certain

    However I never said that.

    I think you can't really count dried fruit as the sugar is so much more condensed, and bananas a possible exceptions also, but most other fruit is mostly water - however I'm worried asI'm no expert and I'm cutting and most days I have half a tin of chopped tomatoes, an apple, carrot, satsuma or two, possibly a nectarine or peach, and a very small amount of sweetcorn (lhalf a very small can). This is most of my carb intake however - I may also have a wholemeal pitta, or just some fats - and some wholegrain toast on weights days too. Can't fructose be used for neither glycogen or fat, but just body fuel, as in daily calories to keep you going?

    But I assumed that the fibre in fruit meant low GI, therefore good.

    It would happen in theory but in practice could anyone eat enough fruit over a long enough period to cause any real weight gain. Even smoothies are pretty filling.

    Fruits don't make bodyfats levels rise per se, excess calorie consumption can do this so in theory you could go into calorie excess by over eating fruits. Fruits in general aren't that calorie dense a food, their calories generally do come from sugars in the form of fructose and glucose, but this is of no significant consequence if you are still in calorie defict.

    The only time avoiding fruit should be considered is during a extremely low carb diet (comp carb depleting). For the recreational trainer, fruit's benefits far outweigh the cons, and assuming a sensible diet is in place will not affect cutting.

    Dried fruit will of course be much more calorie dense than fresh fruit. Fructose will mainly replenish liver glycogen, this can then contribute to blood glucose (for whole body if/when needed). If the liver's glycogen levels are high it may be converted to triglycerides and contrbute to bodyfat, this will only be likely during a high calorie/carb intake.

    Fruits G.I varies quite a bit dependant on ripeness and variety. Its low G.I could be a result of both fibre content and the fact that fructose is is very slowly converted to glucose (in the liver). So the reason's are metabolic aswell as digestive.

    I would hope not. Fruit forms the cornerstone of my diet and gets me through the working day when i feel peckish and need a snack. As far as Im concerned, when faced with a touch of hunger, if its a bunch of grapes, an apple, orange or pear versus a bag of Crisps or a mars bar then there's no comparison.

    I guess its all down to being sensible...
