Fasting for wedding

I'm wondering if 16:8 fasting will give me the results I'm looking for for my wedding in 3 months? I'm already slim, but definitely with some flabbiness/visceral fat. 25 yo female, 5'3, 115lbs. sedentary lifestyle and would just like to slim down/tone up a bit, maybe lose like 5 lbs. I've done 16:8 for 4 days (not super strict and not during weekends). Do you think I will see any meaningful progress towards my goals with this routine? I should mention I am a super snacker, both in morning and at night. my eating window with this routine has been 11am-7pm.
