Did a kinda diet like that for a 2 months. Ate normal foods, except I stayed away from stuff with added sugar like sift drinks, pack juice, sweets, doughnut boys,, etc.
Stayed away from flour nearly as much, so roti and Dumplings were out. Breads were restricted to mornings
Cut down the added oils, but left the fats on meats.
Kept rice to about 2 to 4 times a week
Provisions to about the same.
I increased the amount of fruits as snacks, so instead of drinking a soft drink, had some water and fruits and nuts instead.
Mainly I ate beef steaks with steam or chunkay veg.
Sometimes I ordered talkarie with out the roti, and ate it with a spoon.
Although I didn't do additional exercise, at the time my job was physically demanding, and helped burn a lot.
I dropped at least 20 lb in 2 months.
Felt great, lots of energy, just wanted move all over .
But things came up and I could keep it up, and up to now I haven't settled back.
It isn't as strict as professionally designed diets, but it for did work, and when the weight started to drop in 2 weeks in, it dropped quickly, but I felt awesome.
All in all, I was inspired by naked and afraid. I devised it from thinking, what would people eat before any big technological advances in society... essentially a hunter gatherer diet.
