I did 18:6 for about 6 months a decade ago and noticed the hangry effect (as did my wife and kids!). I went from 232 to 190 lbs though, placing top 5 in triathlons, so the method undeniably works. It's been 10 years and I found myself back at 225 and decided to get back on the IF wagon in December, with one modification: I stop eating at 9 pm and start at 3 pm, so by the time I encounter my wife and kids, I'm not hangry.
