That is correct. The more you raise insulin, the lower the blood sugar afterwards, especially if the foods digest quickly.
Whole grains will take longer so less hunger.
Rice and floury breads are immediate while fruit is the fastest and contains a lot of sugar (higher spikes).
Add fibre and everything slows down (veggies)
Add good fats and it works as well as fibre however it will also keep you fuller for longer.
Don't be afraid of adding more fats while of course controlling your carb intake.
It takes a full hour for your body to use 10g of carbs and you can not use stored energy for usually 3-5hrs after digesting food due to insulin in your blood stream so avoid snacking (no fat loss during any of this time).
