II mum 7 lbs in 3 weeks is very good I think your expectations are just off. You really don’t want too loss more than two pound a week unless you really know what you’re doing, most off the time when someone is losing more the 2 pounds a week all they are doing is playing around with their hydration levels without even knowing because of their diet and not only is this really not weight loss “fat loss” but it’s also very unhealthy. So try to be more patient.
