Ttc baby no. 3 should I loose weight first?

Hey ladies. So I am 28 and my boys are 5 and 2.5 my husband and I were talking and I want to have a other baby. That being said I don’t want to get pregnant again for maybe another 6-9 months we have to move into a better place and such but I’m worried I won’t be healthy enough for this baby. My pre pregnancy weight with my first was 145 and my pregnancy weight with my second was 155 right now I’m 160 😪 and I’m 5’3” I don’t feel like I look overweight or feel it but evidently I should be 35 lbs less. Do you think I should go on a very strict diet to loose the weight sooner or let it happen on it’s own before I get pregnant. I know it’s a weird question I’m just not sure if my weight is too high to sustain a baby.
