5kg in less than two weeks is a concern, you will be losing muscle as well as fat. And you don’t want that, as honestly you will hate your appearance when you hit goal.
its important to do this right, ensure you eat your macros, sufficient protein to protect muscle, strength training, for the same reason, lose no more than 2lbs a week,
I’ve been on it well over 2 years, maintaning for 18 months on a maintenance dose, lost over 6 stone, and I’ve lost count of the amount of women who are upset as their bodies are saggy, maintained their tummies, lost hair etc.
i have no idea how normal people feel, we are all normal. But you should get hungry for meals, be able to pace yourself and be full after a healthy portion
rapid weight loss is going to see you have real issues, so take a step back and do this right.
