This is important because most people “losing weight” have made one change to their diet and exercise program while simultaneously eating more or otherwise cheating. However it feels like they are more healthy, and the trend line seems to agree. (Often they are much healthier, just not changing weight but redistributing it, but measuring that is far harder).

People eventually get jaded of the false progress cycle and give up on weight loss because it feels impossible. An app implementing this system would be of great help.
