If I want bigger muscle do I have to let them reach the highest amount of body fat then have them work it off? I got one of my Sims (he'll be mentioned below) a little above the max amount of muscle on the slider but I want to make sure he doesn't get to the highest amount of body fat if possible. If I don't want them also gaining weight from the food because of higher calories but want them to gain more muscle, do I have to make sure their hunger is in the orange or red before feeding them high calorie foods or will it not matter? I remember reading somewhere (on ) that if you want your Sims to bulk up, you have to feed them foods with higher calories and have them lifting weights.
