If you’re stopping off at McDonald’s for a bite on the run, one sandwich option that proves to be quite popular among many is that of a Big Mac. But before you sink your teeth into this extra large sandwich, you may want to take into account what nutrients it will be providing you with.

It may taste good with it’s melted cheese and “secret sauce”, but it’s no secret that a Big Mac can wreak havoc on your fat loss if you’re not careful. Let’s take a closer look at Big Mac nutrition facts so you can see for yourself what this sandwich can do to your weight loss efforts.

Major Nutrients Found In A Big Mac

Potentially one of the biggest problems with the Big Mac is its high saturated fat content. At 29 grams of fat total as well, this is going to put a huge dent in your daily fat intake. In addition to this, a Big Mac also packs in a whopping 1040 mg of sodium, which is half of what most people should take in during the course of the day.

When your goal is weight loss, a Big Mac can spell trouble with 540 calories per sandwich. If you add fries and a soft drink to complete your meal, your calorie count can easily exceed 1,000 calories!

The Big Mac is also relatively high in cholesterol so anyone who is concerned with their heart health will want to take note of this and possibly avoid it for this reason. If however you monitor your cholesterol before and after your trip to the golden arches, you can eat this with less guilt!

On the plus side a Big Mac will supply a whopping 25 grams of protein, an essential fat burning nutrient and a small amount of potassium and calcium so you can easily meet your daily requirements for those nutrients.


When selecting your Big Mac, if you can request it to come without cheese or any special sauces, this will improve the nutritional value for it, so something that you may want to consider. A special order will help you reduce calories, but if you want the real thing make sure it’s fresh without wilted lettuce. If you can’t part yourself from all Big Mac ingredients, forego the special sauce and use plain old ketchup!

Always consume a Big Mac fresh for best taste as even if left for a few hours it will definitely not be tasting nearly as good. But if you can’t eat it right way, microwave it for less than a minute inside the box. You may also want to cover with a damp paper towel to keep the bun feeling and tasting, like a Big Mac bun.

Eat It With:

Sadly, the Big Mac is most often served with fries and a large soft drink, but in order to do your diet justice if you are going to have this, opt for a salad without dressing instead and serve with a water. Since the Big Mac is technically 2 burgers (it is), don’t eat it with anything else. Simply order water or tea and enjoy this hearty sandwich. Eliminate a few additional calories by taking out the middle bun!

{This so-called “Mega Mac” will do twice the damage as a traditional Big Mac!}
