I had an amazing diet that worked for me.
It's called "Stop eating so much and go exercise".
I was skeptical of this diet, thinking it just another fad. At first there was no change. I stopped drinking pepsi/dew/etc and starting drinking tea with no suger (although sometimes I do put equal in it). I stopped getting cookies/chilli cheese frys/fast food for lunch and instead eating salads, sandwiches, etc. I starting having smaller portions at dinner (no more 16 oz steaks and half pound mash potatos with veggie side, cheese stick appatizers, and deserts when I go out).
Then on top of that I started walking every day for 30 minutes, then jogging, then eventually running. It was tough and man did I hurt. Then I started strength training, again man did this hurt a lot. All this time I didn't lose a single pound. I was sure this fad diet wouldn't work, I mean it had been like a month. I got into competitive sports (judo/bjj/mixed martial arts) and finally i started losing weight and then I realized why.
Cutting down my diet helped me stop gaining weight. But I was not doing enough exercise to counteract me food intake. This is because I did not push myself. I worked only until I was tired or bored. Competitive sports forced me to work beyond what I thought was reasonable. Once I started pushing the limits of what I thought was possible (hundreds of crunches instead of dozens, 50 pull ups (even if that ment it took 15 minutes or more), medicine ball workouts, running sprints until I could no longer stand, man the weight starting to shed off.
Next thing I know my clothes no longer fit I went from a 36 inch waist in jeans to a 32 inch. I could wear tshirts again without my belly showing, etc. Then this muscle tone starting showing up, and I started being hungry all the time. It turns out, if you try this fad diet, eventually you can increase your food intake because you burn so much energy working out. Now I can eat almost whatever I want (usually once a week we go out to a steak joint and I really chow down) and maintain a consistent weight. I balance around 155-160, which is almost my highschool weight.
On top of all this, this fad diet actually cured other problems I was having. My 'bad' back suddenly no longer hurts me, my wrist problems are gone, I stopped having migraines, my allergies cleared up, as my flexibility improved I found my general aches and pains went away and I got hurt less while working out, I can carry heavy things now and open jars in the kitchen for my wife, my wife suddenly wants a lot more sex and I am suddenly wanting to provide it a lot more often and for a lot longer, and people seem to listen and respect me now.
It's really an amazing fad diet, someone should write a book on it.
