A Snickers bar has a medium GI because peanuts and fat slow the sugar, but a full bar has a high glycemic load. A fun-size bar is a better treat portion.
Glycemic load by portion size
GI stays the same whatever you eat, but glycemic load scales with the amount: eating twice as much doubles the effect on blood sugar.

|---|---|---|---|
| 50 g | 30 g | 20 | High |
| 100 g | 59 g | 41 | High |
| 60 g · 1 regular bar | 36 g | 25 | High |
| 120 g · double serving | 71 g | 49 | High |
