Irish man who proved he could eat McDonald’s every day and lose weight reflects on impact of TikTok challenge

A personal trainer who proved that weight loss was possible while eating McDonalds every day is sharing his reaction to his viral TikTok post almost a year on.

Oisin Mulligan documented himself eating an item off the McDonalds menu every day for two weeks to destigmatise people’s attitudes towards so called “bad foods.”

His first post went viral overnight and has gained over 700,000 views on TikTok to date. He was completely blown away by the public’s reaction to his initial video, but is glad that it received such positive feedback.

“It was probably one of the best things I’ve ever done on social media. I got great fulfilment from being able to help people out that have been struggling to lose weight for years. That’s what my job as a personal trainer is,” Oisin says.

Oisin, who graduated with a degree in Sports Science from Athlone Institute of Technology, says his motivation for the challenge was not to encourage eating McDonald’s on a daily basis, but to show people they can enjoy their favourite foods guilt free when consumed in moderation.

He ultimately lost weight through the challenge while eating dishes such as Big Macs, 20 piece chicken nuggets and large fries.

Oisin says his own personal experience with weight loss has shaped his approach towards clients embarking on their health journey.

“Personal trainers need to be a little bit more empathetic or understanding when it comes to people that have gained weight or are struggling with their body image. I think that’s why I’m a little bit different, as are my videos. I’ve been overweight and I’ve lost it, I’ve been over 110 kilos and came the whole way down to 70 kilos on my own,” he adds.

Both Oisin’s Instagram and TikTok were flooded with comments after the initial post, with the video receiving 200,000 likes over the course of a day. The video also provided a boost for his business, with many people enquiring about his services as a personal trainer via Instagram.

He also hopes that challenges such as these will highlight the misinformation that can spread about dieting and healthy eating. Some personal trainers can contribute to this narrative due to inadequate or little training, he believes.

“Some personal training courses are just two weeks long and you might not even spend a day of it in the gym. It’s not anywhere near enough time to be in charge of another person’s health or wellbeing,” Oisin says.
