I'm not sure what your referring to. You can find lists of high glycemic foods online. Avocados are notorious for causing weight gain and figs are high calorie. If you want to find out if you have the body type that will gain weight on high glycemic foods you can read Gabriel Cousens book, Conscious Eating, where he has lots of information on how to personalize a raw food diet according to your body type.

You can find information about the glycemic index on this website:

http://www.glycemicindex.com

Under "GI Database" you can enter a food name and then you get a list of the glycemic indexes of the different forms of that food (for example an overripe banana has a higher glycemic index than an underripe one, baked potatoes have a higher one than cooked ones, juices fruits a higher one than the whole fruit, etc.).
