Back in the 80s I tried the whole low fat thing and indeed stuck with it for a whole YEAR. I lost a TON of weight. Way more than I have ever managed to lose on LC. I got down into “normal” sized clothes, not plus sized. However:
1) for that entire year I was hungry just about every waking minute of the day. I could never stop thinking about wanting food.
2) I actually had food porn dreams all the time. I would actually have dreams about eating cakes and donuts ancd ice cream-almost every night. Cravings were always intense.
3) I lost my total social life as I could not bear to watch other people eat food. And just about all social occasions involved food, so I just stopped socializing and became a hermit.
4) I had to stop having lunch with my co-workers for the same thing. I’d always be ravenous and could not stand watching skinny co-workers chowing down.

I only stuck it out as long as I did as I’d made a new year’s resolution with a co-worker who was trying to quit smoking. I vowed that as long as he stayed off cigarettes I would stay on my diet.

Except that after a year he was still not smoking, and I was getting more and more miserable with each passing day. I was majorly depressed, felt like life was not even worth living.

And finally, after a year, I snapped. Said, “Screw it! I’d rather weigh 300 pounds that live like this for one more day!” and just began eating everything in sight-so that of course eventually I was well over 300 pounds.

My co-worker never did go back to smoking though.
