The 40 piece Chicken McNugget is the most substantial meal available at McDonald’s, according to calorie counts published by the fast food chain. At 1,880 calories, enough energy is packed into 40 chicken nuggets to provide lunch for a family or group of friends, and close to the daily average recommended caloric intake for an individual. The Big Breakfast with Hotcakes and a large biscuit is second on the menu, with 1,310 calories. 
 
 24/7 Wall St. reviewed roughly 500 McDonald’s menu items, including burgers, sandwiches, salads, beverages, and sides, to determine the most calorie heavy options available at the fast food giant. Most of the highest calorie foods from McDonald’s are larger sandwiches such as the chicken club or large portion items such as the 40 piece Chicken McNugget. 
 
 The size of the item is not the only factor in its calorie count. The 16 ounce McFlurry with M&M’s contains 930 calories, and the Large Oreo Frappe contains 810. While each of these drinks is equal to roughly half the recommended daily intake of 2,000 to 2,800 calories, as beverages they might be only part of a much larger meal. One chicken sandwich, medium french fries, and a McFlurry — an entirely plausible lunch order at McDonald’s and likely one of three meals in a day — has well over 2,000 calories.

 McDonald’s meals have more calories than home-cooked meals and also food served at most non-fast food chains. But while the obesity epidemic in the United States is widely linked to high calorie consumption, no studies demonstrate a direct link between McDonald’s specifically and adverse health outcomes. Academic research does, however, show high concentrations of obesity and other negative health outcomes in areas where there are high concentrations of fast food restaurants of any type. 
 
 Calories represent the amount of energy a body can generate from a given portion of food. Carbohydrates, fats, and proteins are all processed by the body to generate energy, or calories. Therefore, since energy can come from different food sources with varying nutritional benefits, calories alone do not tell the full story. An item with relatively few calories, for example, may have more sodium than a higher-calorie alternative. With 630 calories, the Premium Grilled Chicken Bacon Clubhouse Sandwich provides what would constitute an ordinary meal in calorie count. With 1,740 milligrams of sodium, however, the sandwich has nearly the most sodium on the menu. 
 
 To identify the 50 McDonald’s menu items with the most calories, 24/7 Wall St. reviewed nutritional information for 500 menu items as listed on McDonald’s Corp. (NYSE: MCD) website. For similarly branded items of equal caloric value — the Quarter Pounder with Cheese and the Quarter Pounder Deluxe, for example — only one item was considered. Fat and carbohydrates measured in grams and sodium measured in milligrams also came from McDonald’s.

 McDonald’s Corp. (MCD:US), which sells 750-calorie Double Quarter Pounders with cheese, will start offering fruit, salads and vegetables instead of fries with value meals in a push to get its diners to make healthier choices. 
 
 The world’s largest restaurant chain also will only advertise water, milk and juice for its kids’ Happy Meals, according to a statement yesterday from the company and the Alliance for a Healthier Generation, a group founded by the Clinton Foundation and American Heart Association that works to reduce childhood obesity. They didn’t specify the type of vegetables available. 
 
 McDonald’s and rivals have been trying to shed their image as purveyors of fatty foods in a nation where about two-thirds of the population is considered overweight or obese. While the Oak Brook, Illinois-based fast-food chain in 2012 introduced a lower-calorie menu, Americans are loathe to eat their vegetables, Chief Executive Officer Don Thompson has said. 
 
 The changes announced yesterday are being made in 20 markets (MCD:US) globally including the U.S., Australia, Germany, France, the U.K. and China. They will start within three years and be effective in all 20 markets by 2020. 
 
 McDonald’s fell 1.1 percent to $97.12 at the close in New York. The shares have increased 10 percent this year, compared with 19 percent gain for the Standard & Poor’s 500 Index. 
 
 Salad Sales 
 
 At McDonald’s, salads make up about 2 percent to 3 percent of sales (MCD:US) at U.S. restaurants, Thompson said at an investor conference in May. The chain is focusing on selling beef, chicken, breakfast and drinks, he said. 
 
 “I don’t see salads being a major growth driver in the near future,” he said. 
 
 Fast-food chains are trying to balance selling calorie-laden fare with a few healthier options. While Burger King Worldwide Inc. (BKW:US) earlier this week added reduced-fat, reduced-calorie French fries to its menu, it also recently added buffalo chicken that has 940 calories in five strips and a burger topped with fries. 
 
 McDonald’s introduced a Favorites Under 400 Calories menu last year and this year started selling egg-white sandwiches. In the past month, however, it has been rolling out new items including fried chicken wings (480 calories for five pieces) and a 680-calorie steak, egg and cheese bagel. 
 
 “We want to make sure we provide you the options so you can come in and get whatever you want at McDonald’s,” Thompson said at the conference earlier this year. “So one day get that Big Mac; it’s only 540 calories. Another day, you might want to get that grilled chicken salad.” 
 
 McDonald’s has more than 34,700 restaurants worldwide, and 81 percent of those are franchised.
