Three days is nothing.
I’m at over 4 months, and my weight loss is noticeable, but not too astonishing. For nearly two months, after the initial 4 weeks, I kept hovering around a particular weight, apparently my body’s set weight. Did some exercise (because I felt like it) and ate rather healthy, but it didn’t do much.
But now, when I failed sticking with exercise due to too many other stress factors and mesed up schedules, and even had carbs during Easter, my weight suddenly started dropping again.
It takes a lot of patience to lose weight, not so much exercise. Excercise helps build muscle and strengthen bone when done right, and that means your weight goes up. Too much excercise (or other stress) causes more cortisol, which makes your body hesitant to let go of fat.
Try to relax as much as you can, really feel that life is wonderful. This works wonders even without any weight loss diet. The diet only makes it faster, and helps people who don’t feel too strongly how wonderful life is.
Eating to satiety is sound advice. That doesn’t mean you should eat a lot, but rather that you eat fewer times if your meals are large, or end up with a calorie deficit if you don’t feel like eating much. I ended up eating rather little for the last few days, just because my body didn’t want thay much. And that’s how my weight started moving quickly.
