For three weeks, I ditched 16:8 completely and did 5:2, where you eat normally for five days of the week (I ate from 10 a.m. until 8 or 9 p.m.), and 500 calories on two non-consecutive days. I chose to fast on Wednesdays and Sundays, fasting all day, and eating my 500 calories in the evening.
By the end of the third week, I lost about two pounds. The before-and-after photos basically look the same. I could tell I was more bloated in the "after" photo, but I could also see that my face and belly looked a tad slimmer.
I wasn't a fan of 5:2 since eating so few calories on my fasting days made me hangry, but it did help me feel less puffy. I happily went back to daily 16:8 intermittent fasting.
