KS are you using an activity tracker/HRM?
I found these a revolution in helping to control weight – particularly as the Garmin ones integrate directly into MFP.
Exercise calorie burn figures based on GPS and heart rate data opened my eyes to what is actually being used, again it is not 100% accurate but the data is a true reflection of effort rather than a finger in the air.
A few people will tell you that these are just a toy, but by applying the data produced I could accurately predict what the scales would read on Saturday mornings.
You are doing great though, While the ‘Eat less move more’ calorie restriction model should work, it seems that the body will throw in some feedback loops that will cause the weight loss to stall.
Stick with it, a bad week can be disheartening, but it can also be motivating, remember you are still way ahead of your target.
