Eating out

Jus go subway.

Healthy has more to do with how your overall diet looks rather than a single meal. In other words if you eat mainly nutritious foods, and eat out and have a Big Mac while fitting it all in your calorie goal, that Big Mac does not destroy the nutrition you ate, and can be a part of an overall healthy diet.

My personal suggestion is simply plan your whole days eating ahead of time looking up the calorie information for wherever you are planning on eating. Fit it in your calories, and you are good to go.

I eat out fairly often
Ideas I have used/use:

• soups for starter - skip the bread
• fish preferably grilled and know your low cal ones over your fatty ones
• Salads ask for dressing/croutons on the side add to taste but not the restaurant way
• Check out the portion sizes (other tables) order starters as a main when they are large
• Go vegetarian when that is a good option (Had the most delicious beet burger once) Be careful though often lots and lots of cheese when meat is left out not always low cal
• Have a very small breakfast and lunch so you have margin
• Plan a low cal day the day after to even out a bit
• Opt for a good place not fast food - often they can accommodate special requests.

I am not a dessert person so I tend to skip those and have a cup of tea instead

There are a limited number of restaurant options where I live. I don't know what restaurants are in your area or what your goals are.

Plan and look stuff up if you want to eat out. Chain restaurants have nutritional info usually so I look up and plan in advance something that fits my goals for the day. Non-chain restaurants I usually find something similar to log.

Watch portion sizes. Watch condiments/sauces/dressings. Don't fill up on breadsticks, rolls or crackers if you need protein and vegetables.
Soup or a baked potato may be a lower calorie option at some restaurants.
Vegetables and fruits are more difficult to get at an average sandwich place. Most places have a salad though. You can often have regular/small sandwich with a side salad instead of fries or chips.
Chinese restaurants have more variety of vegetables available. Watch rice and noodle portions.
Sodium can be high with restaurant food. If it is a concern for you then you may need to be more careful what you order or not eat out much.
You can save calories at a pizza place by getting a thin crust. Choose things like chicken and vegetables for toppings if you want fewer calories and add to nutrition. Eat less pizza and have a salad with it.
I drink unsweetened tea or water and most places have that option as well as diet sodas.

I would generally be looking at getting some protein, not fried, not slathered in cheese and bacon, not super sized portions. It is one meal a week for me so I don't stress about it being nutritionally complete. I would not order a triple bacon cheeseburger with fries and a peanut butter shake with my calorie goal.
