Looks like i eat a lot of garbage. I had never cooked a thing in my life. When my wife passed away unexpectedly i ate one meal a day. If it couldn't be done in the micro wave i didn't do it. Went from 242 pounds to 175. 3 years of that and decided i should learn to cook a little. Still not much though. Most things now are either fried or done in the crock pot. Still use the micro a lot too. I HATE cooking.
If you hate it it doesn't matter.
Not sure where you live but the Williams and Sonoma or the Sur La Table stores have cooking demo and teach you how to do simple things like grill, roast, pan roast, and saute (fry in a pan with a little oil)
The big part of making cooking come out good is how you treat the product. Steak on the grill, let it sit and don't poke it, when it is off the grill let it sit for 5 or 10 minutes (based on thickness) and when you cut into it it will not bleed juice all over. If you are happy with what you eat then keep doing it, if you wnat to impress someone or take some pride in making a few things really well, then look for cooking classes near you. May meet someone that wants to cook for you and you can be back to 242 in no time.
