Hey a little help please ;)

@mpe, for the sucrose, as well as the 2.91 mmol/g of glucose, doesn't that also have a more or less equal component of fructose that will also metabolise as carbohydrate, albeit via a different metabolic pathway? So actually the total carb per g is very close to that of starch.

Edit: and similarly, lactose is also a disaccharide, with galactose + glucose vs the sucrose disaccharide with fructose + glucose.

Sticking with carbohydrates which only contain glucose the numbers would be
maltodextrins: 5.94-6.24 mmol/g glucose (the longer the "chain" the higher the number)
maltose: 5.83 mmol/g glucose
glucose: 5.55 mmol/g glucose.

Even these apparently small differences can be very significent in people eating several kg a week!

Where fructose and galactose differ from glucose is that they NEVER need insulin to be taken into any human cell.
(The rules for if insulin is needed for glucose to be taken into a cell can be very complex, especially for myocytes.)

The usual state of affairs is that fructose and galactose tend to be metabolised more or less exclusivly by the liver.
(Only in hepatic portal vein does the blood contain anything other than trace amounts of these sugars.)
With the most common metabolic pathways here being respiration and lipogenesis.
Converting either sugar to glucose is a possible, but unlikely, metabolic pathway (especially without then storing it, as glycogen, within the hepatocyte in question). (If the human body actually needs more glucose there are various GNG metabolic pathways which are more likely to be used.)

Edit: and similarly, lactose is also a disaccharide, with galactose + glucose vs the sucrose disaccharide with fructose + glucose.

The ways in which the human body treats fructose and galactose are similar. They are different from the ways in which the human body treats glucose.
 
I didn't realise fructose and galactose don't require insulin. I knew there was a different pathway for fructose but I thought it still had a carbohydrate as its endpoint and so would still require insulin at the endpoint stage (like the maltodextrins etc do). That's really interesting, thank you. I already avoid fructose and lactose when I can because of these complications. But avoiding sucrose is pretty difficult other than by avoiding prepared foods altogether.

Hi

I haven't posted in a while so quick summary about me I'm 23 will be 24 in June was diagnosed t1 8 - 9 years ago - current hb1ac is 6.2 ＼(^o^)／ took years but now my bg is quite stable.

Recently went to visit my doctor and was praised regarding my bg but then he went onto a sore subject which was my weight T^T

I eat well currently eating 70 - 80% raw (loads of green poop) I exercise 30 mins - 1 hr a day since November and I've only lost 3kg now I weigh 100kg - I know I have a major problem on down days ( I'm bi polar) which aren't predictable and there's also the red lady who vists once a month - and I can't help my self so I tend to munch on pre packed snacks but still always under 1600 calories

Here's my problem I want to lose weight really badly I have tried the hard way and it doesn't work - my body builder friend recommended a diet pill which he uses to stay lean call t6 I've read reviews and as usual there are pros and cons - but I want to know if its ok to use it as a diabetic

I am currently on 58 unit of lantus ( big does which I want to reduce with weight loss) and I am on a 1:1 novorapid ratio

Please I want genuine help - p.s if my replies seem snappy or down please do not panic I'm probably having a down day/week

Thanks in advance

keep your food intake at about 1400 calories a day and you will lose weight - it takes guts but the result is a healthier you!
