time-released energy

[unpakwon]

I don't understand "time-released" and "spikes up and down" in the following. Please explain them more easily.

Scientific syudies also show that protein helps stabilize blood sugar levels when it's consumed with carbs which contributes to a sort of 'time-released' energy as opposed to spikes up and down.

Thank you.

'time-released' energy as opposed to spikes up and down.

The energy is realeased steadily over a period of time rather than in bursts of high energy with times of low energy in between.
