It's actually crazy. I'm also on a calorie counting and fitness schedule and eating out is insane.
For example, somewhere like Slug & Lettuce you can get a veggie burger and fries - it is 950 calories (seems like a lot), then you realise the fries are an extra 450 calories on top of that and weren't included. That's 1400 calories on a meal that doesn't even fill you up.
At home I can make a stack of homemade chips, do a double burger, throw cheese on, make a decent salad, and it won't hit 1000 calories.
No wonder the country is struggling with its weight. How can this food have so many calories in for next to no substance? It is ridiculous.
