Perhaps, but it seems to me at this point in time most every variety of special diet has been tried, and I've never heard of a low fat high carb being effective, whereas there are MANY thousands of people that rave about the amazing effectiveness of a low carb high fat/protein diet.

If you have evidence to the contrary, preferably including a forum of people who have had success, but even just the common name of such a diet, I'd be quite interested to read about it.

> Take raw potato with <1g of fat on a kilo, and french fries that have 154g of fat per kilo! Are carbs from potato the problem?

From anything I've read, the answer is yes, the carbs are the technical problem, but another at least as important factor is: french fries are delicious, so you'll eat 3 times as many.
