1 week in, still feel nothing much, but 4 pounds dropped

I started last Sat so it’s officially one week. I’ve been keep thinking why I didn’t feel much but magically I still lost 4 pounds. Here’s some feedback:

Feelings:

1. Still have food noise. I still can grab ice cream or snacks and happily eat them
2. No appetite cancelling either. I still think all good foods look delicious
3. Hunger now feels a bit different- it’s a distant feeling that doesn’t make me uncomfortable or cramp. I know I’m hungry but that hunger is ok to bear with.
4. I feel digestion is slowing down. I get full longer so 16 hours fasting doesn’t feel painful.

Things I do that probably mainly drove the weight loss:

1. I gave myself a new 1400calories goal. I still eat close to 0.8g/lb protein.
2. I kept twice a week weight training, twice a week yoga, and once or twice cardio.
3. 16hours a day fast

Some thoughts for next week:

1. I’ll probably increase my calories to 1500. 4lb a week guaranteed a muscle loss. I want to control it to 1-1.5lb/week.
2. If this keeps going, I can happily stay in this dosage.
