The two new sizes are the Mac Jr. And the Grand Mac.Fans who can't commit to a regular sized Big Mac now have the option of a single patty version of the burger. The Grand Mac, for those who think. The technical definition of a calorie is the amount of energy required to increase the temperature of one gram of water by one degree Celsius. Since that is a very small amount the 'calories' shown on food labels are called such, but are actually kilocalories.

At McDonald's, we take great care to serve quality, great-tasting menu items to our customers each and every time they visit our restaurants. We understand that each of our customers has individual needs and considerations when choosing a place to eat or drink outside their home, especially those customers with food allergies.
The technical definition of a calorie is the amount of energy required to increase the temperature of one gram of water by one degree Celsius. Since that is a very small amount the “calories” shown on food labels are called such, but are actually kilocalories.
In other words, one calorie on a food label is equivalent to 1000 calories by its technical definition. But, from here out, we will be calling both calories, even though we know that food calories have a different value.
Here is how much energy is contained in one gram of the following substances:
Carbohydrate: 4 calories
Protein: 4 calories
Lipid: 9 calories
By calorie amount, nutritionists recommend eating a diet that is 40% carbohydrate, 30% protein, and 30% lipid – keep in mind that 30% lipid means that 30% of your total calories can come from lipids, but because lipids contain more than twice the caloric value protein or lipid, only 13% of your total food by weight should be lipid. So, lipids contain more calories (and more energy) per gram than other protein or carbohydrate..
Before you begin, answer the following questions:
- Why do nutritionists recommend eating about 30% of your calories as lipids, but only 13% lipids by weight – what’s the difference?
- Do you think your diet contains more carbohydrate, protein, or lipid by weight than the other organic molecules? Why?
- Based on calories of carbohydrate, protein and lipid alone, do you think the meal you calculate for McDonalds, Chick-fil-A, or the homemade meal will be the most balanced?
Your task is to calculate the following values for (1) a McDonalds meal, (2) a Chick-fil-A meal, and (3) a homemade meal (using Calorie King):
- Grams of Carbohydrate
- Calories of Carbohydrate
- Grams of Protein
- Calories of Protein
- Grams of Lipid
- Calories of Lipid
- Total Calories
After you’re complete, answer the following questions:

- By calories, what percentage of your diet is carbohydrate, lipid, and protein?
- Was your prediction that you eat more carbohydrate, protein, or lipid than the other organic molecules accurate?
- How true was your prediction about which meal – McDonalds, Chick-fil-A, or the homemade meal – was the most balanced?
