I am truly amazed that everyone is going crazy over a fast food joint. This is the reason America is obese and unhealthy. People are willing to wait in long lines, fight traffic and feed their KIDS crap, sorry but somebody had to say it....
You can also just order a single hamburger, skip the special sauce and use mustard instead. You can get water, tea or diet soda and either skip the fries or share one order of fries with your group.
That would cut the calories way, way down. You could even order extra tomato for the burger to make it slightly healthier.
You can eat there without consuming anyway near 1700 calories and 60 grams of fat in one meal.
A single hamburger with ketchup and mustard instead of sauce is 310 calories and 10 grams of fat. You can drink water, iced tea, coffee, light lemonade or diet coke for zero to about 10 calories. Half an order of fries would add 200 calories and 9 grams of fat.
Less than 600 calories and less than 20 grams of fat even if you go for half the fries.
Skip the fries completely and and it's pretty healthy.
You could even do "protein style" lettuce wrap instead of the buns to cut even more calories and eat it every day without gaining weight.
