Yes! It already has! I rarely eat McDonalds but when I crave it, it's to indulge. I stopped recently for a chocolate shake but changed my mind when I saw it was over 700 calories! I left with no purchase and frankly disappointed. I am not sure it will be good for business but it will be good for my waistline.

I usually indulge in a sausage McGriddle every Sunday morning but once i see the calories, I might have to rethink this habit. Time will tell.

By the comments so far, McD's is losing by 100%. I don't eat there, but it would be interesting to see ALL nutritional facts.....how's the sodium and fat content in that big Mac?

I stopped eating anything from McD's a long, long time ago! If you watch your weight and exercise regularly, fast food chains just don't even enter the picture!

Haven't seen the calorie count where I live but when the prices went up 20 percent this summer that was it for me.

The book Fast Food Nation, gives a myriad of techniques used by Fast food companies including social, cultural, and economic means to get consumers to buy an unhealthy product.

Does it change my mind? You bet! About as much as "No Diving Shallow Water" It changed my mind the first time I figured I could exceed an entire day's calories with lunch at McD.

All moderation........just like a big gulp......Dear gov. You don't need to control my life....

A little like telling someone whose head you are pointing a loaded weapon at how many bullets it contains. Calories are not the important thing here. Animal cholesterol causes cancer, also cause heart disease, diabetes and a whole host of other health problems.

You can stick your head in the sand or find out the facts...up to you entirely.

Oh ya! Thank you McD's for the added incentive to avoid you like the plague. Fast food is TOXIC. Go plant-based w http://www.drfuhrman.com. Avoid and reverse disease caused by the Standard American Diet (SAD). Micronutrients are the key to a long, healthy life. After all, our health is our greatest wealth!

I am on a high protein low carb diet so i just through away the top and middle pieces of bread on a big mac...still my favorite junk sandwich....and when i want to indulge i have a small ice cream...taboo i know but what the heck you only live once! and i have made it this far...(62)

Maybe they can take a page from Burger King's book. Sell packaged apple slices, which I can order instead of fries.
