I created a diet a while back that worked really well for me and I will prolly go back on it by spring.
I tend to lose weight in the winter and gain in the summer, nuttin major but still...anyhow I had cancer once and was very ill. I lost a lot of weight and was skinny and I hated it. Everything hurt and I was always cold. When I got better the docs had me on some crazy diets bevause I was having some issues with my pancreas at the same time. Anyhow, all that weight I had lost I put back on and then some really quick.
So one day I came up with an idea...and it worked...59 lbs of worked!
I used to skip breakfast and often lunch and would be starving by dinner so what I did was reverse it kinda and went from there.
I ate breakfast and lunch at the appropriate times - and I had whatever I wanted, it was often fast food because of work, I even snacked throughout the day on junk, but after 4pm all I could have if I got hungry was cereal. Any kind of cereal and as much as I wanted. Most are now made with whole grains, even cocoa pebbles.
Anyhow, I was never hungry or deprived of the things I loved.
Somehow this switch changed my metabolism and quickly! I lost 15 lbs the first few weeks and I felt great the whole time. After about 5 months I dropped 59 lbs.
So not necessarily doctor reccommended but hey it was great and harmless! But ya gotta like cereal!
