This study showed that continuing to exercise lowered risks of heart disease even if the participants didn't find their superficial goals being accomplished.
Persist. Your life depends on it. I've seen people over the years quit making effort because their body composition doesn't change enough EVEN THOUGH their biomarkers for disease risk have improved or held steady in a safe range. They quit the fitness or nutritional effort because they don't feel they lose enough body fat fast enough, but only to find a few years later their risk of diabetes, cancers and cardiovascular disease skyrocketing out of control.
Don't let perfect become the enemy of good. And in this case don't let superficial looks become the enemy of your health.
