I've decided to commit:
One full month of clean eating and serious exercise. No more diddling around... cheating here and there... skipping the occasional workout.
It's an experiment, mostly.
What kind of results can a human really achieve after just four weeks of clean living?
Well, I'm going to find out.
I'm not going to be super super super strict. That would only lead to failure. But I am going to be as strict as I should be for a lifestyle change. This means paying attention to my meals 90% of the time, and giving myself cheat freedom 10% of the time. It also means skipping workouts only if absolutely necessary (e.g. a medical emergency) rather than just because "I don't feel like exercising."
I strongly suspect I'll lose a pound or two in a month.
