Having a curry tonight .. help, help, help!!

You should ask about which dishes have cream in them. Dishes like Chicken Tikka Masala and Saag Paneer (spinach with cheese) usually have heavy cream. (And, for this reason, are very tasty!) Also, Indian food tends to use a lot of ghee, which is clarified butter. Maybe you can ask your server which dishes are lighter, or maybe they could sub milk for cream in your dishes.

If they have lentil dal (also spelled daal and dhal), that is usually just lentils and spices. Dal and some naan could be a nice, light meal.

If all else fails, get something you want, divide it in half and take the rest home for lunch tomorrow.

It's sooo hard though! Thankfully, you're probably avoiding the lunch buffet and will just be served one plate. I cannot resist piling on all the creamy curries, and I'm a little lactose intolerant to boot.

Yup, splitting it in half is the ticket! Also, can you fit in an exercise session/another exercise session today? That will boost your calorie allowance.

Do what you can to prepare and then just go and enjoy. Be mindful of what you eat and eat modest portions. Focus on the company and conversation and less on the food.

Also, be aware that many curry dishes are very high in sodium which MAY cause you to retain water and thus see a temporary increase in the scale. Doesn't affect everyone that way, but it may impact you.

I love curry and ate it often when I was actively trying to lose weight. But I also made my own, so I could limit the sodium.

Enjoy tonight!

something with at least mostly lentils or other legumes and veggies will be super tasty and filling.
Also, if you can avoid the rice or ask for it to be on he side, that would save hundreds of cals.
1 cup of rice can be 400 cal, and you'd have no calories for anything else.

Maybe chicken tikka with an indian side salad ?

something really spicy with tomato base instead of cream base, vegetarian even better (dahl is a great suggestion though watch out for the ones made with cream and lots of ghee!). poppadoms are lower cal than naan.

most restaurants accommodate if you ask for steamed veg on the side of your main. then divide main in half for tomorrow, and eat all the steamed veg with the rest. use the steam veg as your base instead of rice.

enjoy it and some additional exercise will make it guilt free!

I was going to suggest the Chicken Tika as well also can't remember the name of it but my local Indian serves a dish on a sizzling platter with Onions and peppers.

If you definitely want a curry make sure it is a tomato based sauce with no ceram or yogurt. Have a lentil dish and chapati on the side rather than rice and nan.

I would personally have a vegetable tandoori with salad.

I usually just have something like lamb or chicken tikka and I skip the rice, naan, any and all bread/starchy things. I don't typically have a starter as the portions where I go are rather huge. I also never worry about fat content due to cream or their use of ghee. I use heavy cream and ghee, real butter, full fat greek yogurt, etc. so all that tasty stuff is great as far as I'm concerned!

You've got a ton of suggestion!
The other thing is, even with a healthy suggestion, you may go over a bit. Just don't sweat it! Going over even a few hundred calories shouldn't ruin your whole week. I found MFP sets your calories a bit lower than they need to be, so you should still be losing weight even if you increase your daily intake a bit. So one day in the week with a high calorie but healthy meal shouldn't affect you too much at all.
So go for a healthy option, maybe a bit smaller, but if you do go over, it won't hurt you! Try not to stress about these things too much, or counting becomes a lot harder.
