Wow, great example
IMO, these should be your priorities (in order), maybe it's not optimal for many people, but if my life was out of whack and I wanted to put things in order, here's what I would do:
1- Diet
2- Stretching
3- Sleep/Stress
4- Basic fitness (low-
moderate intensity cardio / calisthenics)
5-
Resistance training
Also, you shouldn't care much about losing (or gaining) weight, the scale shouldn't determine your goals! Muscles are heavy, if you gain muscle, you'll gain weight
That's as much as I can tell you right now, guess the ladies will have to handle this one

, good luck.
