There are:
If four ounces of orange juice contain 50 calories, how many ounces of orange juice will have 175 calories?
There are 81 calories in 50g of roast beef (from average round cuts). .
This depends on the serving size. Usually, plain beef is about 50 calories a cup. That is an 8 oz cup.
There are about 50 calories per ounce in roast beef. It depends on how many ounces of beef you use on your sandwich. No not 50 calories it is 400 calories in a roast beef sandwitch because if you put more than that on it you will get fat. The answer above mine is a great example of what not to take into consideration when thinking about nutrition. One high calorie meal once every now and then will not cause you to gain a significant amount of weight. Start your basis with the first answer, 50 calories per oz of roast beef, and work from there. It all depends on what you add, vegetables such as lettuce, tomato and the like are nutritional, so they will not count for many fatty calories. It is the ingredients such as cheese and mayonaise that you must take care with if you want to avoid gaining weight. What type of bread you use can also be a factor. (Additionally, even at its slowest the human metabolism burns at least 1000 calories even while you are sedintary. Consuming solely 400 calories a day, therefore, would be starvation.)
