Surely less fattening than Big Macs. The main spices found in most South Asian curry powders are turmeric, coriander, and cumin; a wide range of additional spices may be included depending on the geographic region and the foods being included (white/red meat, fish, lentils, rice and vegetables). Thus going light or cutting out white/red meat is way to go. I don't eat a lot of curry but never go for poor choice fast food like Big Macs. I much prefer seafood to any other type of meat. I also take twice a day turmeric supplement said to be anti-cancer fighter, key ingredient in curry.
