Portion sizes are nearly 20 percent bigger than they were 30 years ago, a new study finds.
Researchers say that - despite attempts to add healthier menu options - the number of calories and sodium have increased as the size of burgers, fries and ice cream in our meals have swelled.
Over the last three decades, entrées have about 90 more calories than they once did while nearly 200 calories have been added to desserts.
Additionally, nearly 14 percent of the daily recommended value of sodium has been added to our sanwiches and about 12 percent has been added to our fries and chips.
The team, from Boston and Tufts Universities, says the results show that the larger portions and calories have likely played a huge role in the obesity epidemic crippling the US.
A new study from Boston and Tufts Universities, found that entree sizes rose by 30 calories, desserts by 62 calories and sides by about 14 calories per decade over the last 30 years
Per decade, entrée sizes - in items such as burgers and sandwiches - rose by 13 grams and about 30 calories. Pictured: A Big Mac in a McDonald's restaurant
Fast food has become a staple among the diet of US adults, making up 11 percent of all Americans' daily calories between 2007 and 2010.
This is nearly triple from what it was between 1977 and 1978 at four percent of daily calories.
A report released last year from the Centers for Disease Control and Prevention show that 37 percent of Americans eat fast food every day.
Adults aged between 20 and 39 are the most likely group to consume fast food, with almost half (45 percent) admitting they eat junk food daily.
For the new study, published in the Journal of the Academy of Nutrition and Dietetics, the team looked at menu items from 10 of the biggest fast food chains including McDonald's, Burger King, KFC, Dairy Queen and Wendy's.
Researchers looked at data for entrées, sides, and dessert items from 1986, 1991 and 2016.
The total number of items spiked by 226 percent over the last three decades, roughly 23 new items a year, but it wasn't good news when it comes to nutritional content.
'Despite the vast number of choices offered at fast-food restaurants, some of which are healthier than others, the calories, portion sizes, and sodium content overall have worsened [increased] over time and remain high,' said lead investigator Dr Megan McCrory, a research associate professor at Boston University.
Calories in all three categories increased mainly because of portion sizes increasing.
Per decade, entrée sizes rose by 13 grams and about 30 calories, while desserts increased by 24 grams and about 62 calories.
Portion sizes for sides remained roughly the same, but the number of calories rose by about 14 calories in each decade.
'When we look at the sources of what calories are, they're not supplying healthy nutrients,' registered dietitian Andrea Chernus of Chernus Nutrition in New York City told DailyMail.com.
'It's not a lot of fiber, low in vitamin C and other vitamins.'
The amount of sodium also rose per decade in each category, by about 14 percent in entrées, 12 percent in sides and four percent in desserts, based on daily value recommendations.
One bright spot is that calcium and iron have increased in these menu items, based on data from four of the 10 restaurant that were studied.

Based on daily recommended values, calcium content of desserts increased by about four percent per decade. Pictured: M&M McFlurry in a McDonald's restaurant
Based on daily recommended values, calcium content of desserts increased by about four percent per decade and iron increased by about 1.5 percent per decade.
But, in regards to calcium, Chernus believes this is because there has been a greater consumption of higher fat milk-based products.
'Restaurants have added more options like ice cream, frozen yogurt, milkshakes, and there's been more cheese added to entrées,' she said.
She also warned that excess iron is not good for everyone.
'It can be harmful for certain groups. For example, postmenopausal women don't need excess iron,' Chernus said.
According to the Mayo Clinic, women of child-bearing need about 18mg of iron per day. After menopause, the requirement falls to about 8mg.
Meanwhile the National Institutes of Heath recommend that adult men receive between 19 and 20 mg.
So for example, a Burger King meal consisting of a classic Whopper, side garden salad and Hershey's Sundae Pie consists of about 13mg of sodium - more than half of an adult man or woman's daily recommended level.
Excess iron is stored in organs such as heart, liver and pancreas and can lead to deadly conditions such as heart disease, liver disease or diabetes.
Dr McCrory says she hopes the study's findings lead to research on how consumers can eat healthier at fast food restaurants.
'We need to find better ways to help people consume fewer calories and sodium at fast-food restaurants,' she said.
'The requirement that chain restaurants display calories on their menus is a start. We would like to see more changes, such as restaurants offering smaller portions at...proportional prices.'

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.
Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
