If you dont have access to refrigeration or cooking equipment then you should focus your eating on more portable and storeable options. I suggest that you have a stock pile of almonds on hand as these will be easy to eat as you are on the move and pack a good dose of hunger fighting protein and essential fatty acids. Other options include whole grain cereal bars, nut butters (check out Sun Butter, it is made from sunflower seeds. It tastes amazing and has a better lipid profile than just peanut butter while retaining protein), fruit (most fruit can be stored at room temperature, just make sure you dont buy more than you can eat within a few days or you will have a healthy population of fruit flies in your room). If you find it is hard to work in breakfast without a kitchen you can make instant oatmeal in your room by heating water in a coffee maker (most hotel rooms have them now) and mixing in some raisins or craisins or other dried fruit or even just cinnamon! If you are worried about eating out too much just make sure that when you eat out that you make smart decisions on what you order. When looking at a menu be aware of what it is telling you. Most menus are very detailed and give good descriptions on how the food is being prepared. Stay away from most fried, pre-formed,overly processed, creamy sauced or glazed foods. These usually have a lot of added ingredients and fat that can slow your metabolism or just add an access of unwanted calories. Stick to things that are simply and easily prepared, such as grilled chicken breast or even a simply steak or fish fillet. Whole meat portions that are grilled or baked will have fewer calories, more protein and less added fat than fried or broasted options. If you go the salad route remember that creamy dressing usually are rick in saturated fats and even dressings like french, pack a lot of added sugars. Most places have decent vinaigrette or oil based dressings that usually use olive, canola or soybean oil which have the essential fatty acids that your body and muscles crave!
