Expert reveals what to order at McDonald's if you're trying to lose weight but not everyone agrees

Warning: This article contains discussion of calorie counting that some may find distressing

Gone are the days of having to eat a salad for breakfast, lunch and dinner... according to an expert, who has revealed you can actually enjoy a McDonald's while on a diet.

It may sound too good to be true when you think a Big Mac Combo Meal

has 1,120 calories - and that's for a medium, who the heck gets a medium?

Let's be honest, most of us supersize our fast-food orders and a large one, accompanied by a Coca-Cola and fries, contains 1,320 calories.

Well, for those who are counting calories right now, or just wanting to eat a little healthier, UK-based personal trainer and fat loss coach Rosi May has explained how you can still order and, most importantly, enjoy fast-food.

Sharing an Instagram post with her 230k followers, Rosi said: "This is how you lose weight by eating McDonald's and don't worry I'm not about to tell you to swap your burger for a salad because nobody's going to Maccies for a salad.

"And I'm not going to expect you to change your beef burger to a plain chicken burger, I am going to show you some like for like swaps that you can make.

"If you watch my videos, then you know by now that when it comes to losing weight, you need to be in a calorie deficit."

Being in a calorie deficit simply means that you're burning more calories than you're consuming.

She continued: "Meal number one, we have large fries, a Double Quarter Pounder with Cheese and a large full fat Coke. Altogether this meal comes in at 1,385 calories which for most people is a big chunk of their daily calories.

"So, how can you still enjoy a McDonald's but at much lower calories?

"The easiest swap to make is switching a full fat Coke to a Coke Zero or a Diet Coke which means that you save 212 calories."

The personal trainer then suggests 'swapping your large fries for medium fries' and you'll also save a dollar or so.

But she wasn't finished there, Rosi added: "And then finally, you switch your Double Quarter Pounder with Cheese to a Double Cheeseburger.

"Altogether this will save you over 500 calories and you still get to have a Double Cheeseburger, fries and a drink. But it doesn't take up all your calories for the day.

"And that way you can still enjoy things like McDonald's whilst you're on a weight loss journey. But it doesn't have to be boring, you just have to get clever with it."

While many praise Rosi for her useful advice, it seems not everyone agreed.

Over on Twitter, one user said: "It’s called eat smaller portions."

While someone else suggested: "Skip the fries."

As with many things in life, everything is OK in moderation!
