I'm 47, 5'3" and my starting weight was over 163 and my current weight is under 135. I was enormously helped by going low carb. Nothing else worked for me. I was really badly insulin resistant and hooked on sweets.
I went low carb long enough to lose all the weight. In the mean time I initially ceased all the cardio and just made sure I took a walk in the sun each day.
After the weight came off, I started strength training. I also started eating more carbs and way way more food in general. My fitness pal told me that to lose weight I had to eat 1200 calories a day. It didn't work. Nowadays I probably average 2200 calories a day and I never gain weight. I just get more active or more muscular.
I engage in cardio-type stuff now mostly for the joy of it, not for punishment or weight loss. I get most of my carb calories from sugar or fruit and some sweet potatoes or other roots. I drink a lot of wine and eat a lot of chocolate.
Low carb healed me, strength training heals me, sprinting heals me, eating as much offal and meat and salmon as I possibly can heals me, sunshine and Vitamin D heals me.
