I’ve also been doing 16/8. First few days are a little hard but after a week or so I felt really good. I fast from 9pm until 1pm, going to the gym around 6:30pm I would normally have to force myself, but recently I’ve felt full of energy. I’m also restricting my kcals to around 1700, which is about a 400 – 500 deficit.
Also if I’m not hungry at 1pm I don’t eat until 2 or 3 but still stop eating at 9pm. Its surprising how much less I crave carbs / sugar since I’ve been practicing intermittent fasting.
