[WCIF] Fast updating body mod like sims 3

Is there mod that updates the fat and fit values asap sim does a interaction such as eating or after lifting some weight
I tried to find the values that updates the body nearly per 5-6 hours as default value but unfortunately i couldn't find it
The reason i need this mod is because the normal system in the game doesn't feel realistic to me its like you eat 4-5 cake nothing happens while you eat cake but after 5-6 hours you explode(get fat) all of a sudden, its kinda weird. Also this includes getting muscles that makes the observing a skinny body evolutionizing to a muscle body easier 

In sims 3 your body gets updated even while exercising but i think this is kinda impossible to do in sims 4 but i think we could get a body update after every activity.

TLDR; I don't need faster or slower metabolism i need a system kinda like in sims 3 that makes your body update the fat fit values after(or while if possible) every activity

Note: Gta:Sa fit fat system is probably more identical to that i trying to explain (Sorry for grammar mistakes , bad word usage etc.)
