Message: <blockquote data-quote="Bluetit1802" data-source="post: 739915" data-attributes="member: 94045">The glycemic index is just that - an index. It gives a number but not a quantity. The glycemic load is a calculation that has (apparently) worked out a number depending on the number of carbs in the food. The calculation is the GI x carbs in that portion, divided by 100. If you do this for a whole meal, not just a single item, you have to add the total GIs and total carbs up, multiply them and divide by 100. Very fiddly.It does work to some extent for some people. It didn't work for me. One example was a jacket potato. Very high carb and high GI. Add masses of butter and some other low GI food and the GL reduces dramatically. Sadly, the starch in the potato doesn't and still converts to glucose. Agreed the rise maybe a bit lower, but it is more prolonged. And if that rise is higher than acceptable as it would be with a jacket spud, instead of coming down quickly, it stays at elevated levels longer.</blockquote>
