bread/pasta carbs and fruit/veggie carbs??

Jennifer_Delarosa

Just curious did u loose all your weight on MFP? If so Congrats that is awesome!

I'm by no means an expert on this, but basically the main difference is that most processed food (e.g. white bread, pasta, etc) contains simple carbs which are basically sugar, and fruit/veg (and whole grain products) contain carbs which are fibre. See the overview here:
http://lowcarbdiets.about.com/od/nutrition/ss/nutritionlabels_5.htm

On food labels you can sometimes see the details
Carbohydrates: x grams
of which Sugars: y grams
of which Fibre: z grams

In short - and probably overly simplified and completely unscientific - sugar = bad (although it's useful when you exercise a lot and need an energy boost, e.g. loads of exercise snack bars are basically pure glucose), fibre = good (makes you feel full, helps your digestion).

Having said that, some fruit contain a lot of (naturally occurring) sugar (e.g. pineapple) and you probably shouldn't 'overdose' on them either. And as you've noticed, carrots have quite a bit of sugar as well. But that doesn't mean you shouldn't eat them, just try and alternate with different types of fruit and veg to get a nice balance.

So, yeah, go and get your "5 a day" - and more - and don't worry too much about the carbs in them.

Very unscientific and very much wrong. Sugar is not at all bad. The human body relies on sugar for every single thing it does. Your brain alone requires 125 grams of sugar a day. That said, your body will basically convert everything you eat into sugar (glucose) to support its needs.

Fuelled on glycogen alone the brain requires 125g but the Brian run very optimally on a mixture of glycogen, ketones (also lactose when available) and at this point only requires in the region of 30 - 40 grams - all of which the body can produce itself.

No. The brain using ketones is an emergency anti-starvation survival response. It's not "optimal" at all. Glucose is the brain's preferred, optimal fuel source.

Do you have any studies to support this theory?

First sentence...
"The brain is dependent on glucose as a primary energy substrate, but is capable of utilizing ketones such as beta-hydroxybutyrate (beta HB) and acetoacetate (AcAc), as occurs with fasting, prolonged starvation or chronic feeding of a high fat/low carbohydrate diet (ketogenic diet)."

Glucose is primary...

It is so primary that the body will make it's own if you don't eat it...

I eat all carbs and have had no problem losing weight.

This is an interesting read.

I'm not arguing against glucose as a primary fuel for the brain - I'm saying that it can run just as optimally on a glucose, ketone mix - as your study supports.

Also tiger world is keen to try and suggest that the Brain only does this in starvation mode which is not the case - it will run very efficiently when either in a fasted state or on a LCHF diet.

Cheers for posting the study.

The body makes it's own ketones too! With a much larger resource to pull from.

I would argue that the body is meant to be flexible and run on both. Glucose when it's available and ketones when it is not...

Should I be limiting those carbs as well

NEVER limit fruits and vegetables!!!!!!!!!!!!!!!! EVER!!!!!!

There is this magical thing called google. It holds the key to a lot of information, if used properly you could do your own research and probably get to an answer faster than relying on the forums.

At least that has been my experience.

You will get a better answer, too, if you take note of the URL.

To that I would agree. My thought process is ketones primary and glucose secondary (brain and organ partial fuelling, plus high energy muscle fuelling). I have yet to be convinced other wise.

^^ Yep.


Glucose is what your body needs. Pass it on!

I only every limit fruit when it gets in the way of my meat eating.

sigh.. every time i go read a thread in hope of a quick and easy answer i end up doing research for a whole day lol. cant it ever be simple?? :P

and for the "google it" people: i did google and it brought me here!
