James ‘Arg’ Argent went from skinny to big during The Only Way is Essex series 22.

The TOWIE star opened the series looking thin and trim yet ended the series wearing girlfriend Gemma Collins’s tracksuit.

Apparently, they’re “both the same size”.

Here’s how Arg’s character grew across the 10-episode series, developing into a more well-rounded and rather chunkier version of himself.

1. A Healthy Glow

With a spring in his step and a healthy glow in his cheeks, Arg looked youthful and vibrant as series 22 kicked off.

Here he is smiling gleefully, despite being minutes away from confirming a joint bank account with Gemma Collins.

2. Arg in the Gym!

Sporting a slim-fitting tracksuit, Arg was even spotted in the gym with Dan Edgar during episode one.

Is this guy a fitness freak now?

3. Covering Up

Come episode three, however, Arg had started to cover up.

Was it the icy autumn wind or was Arg trying to disguise extra paddings of winter warmth?

4. The Mexican Creeping in

As Arg surprised Gemma by hiring a Mexican band and asking her to be his ‘official’ girlfriend, we suddenly witnessed his new body composition.

From episode one to episode four, Arg’s clothes were looking a lot tighter.

Damn those enchiladas…

5. Chains Hide Nothing

Despite trying to divert attention to his cheap bling, it was clear that Arg looked totally different from episode one.

Even the hideous gold chain wasn’t enough to distract fans on social media…

6. Sharing a Tracksuit

Confirmation that Arg had completed his body transformation came in episode six when he met up with the rest of the Essex lads wearing ‘The GC’s’ tracksuit.

Claiming they were both the same size, Arg now looked like an oversized Tinky Winky…

7. The Final Product

As Arg bobbed into the room to spark an argument with Chloe Sims in episode seven, it was evident that even his walk had changed due to the weight gain.

This ballooned version of Arg is not the man we saw in episode one, but either way, it seems like he is loving life!
