He allegedly has gained nearly 100lbs in the past year.
But it seems Rob Kardashian is committed to shedding the extra weight.
The 27-year-old is flying out personal trainer Gunnar Peterson to Paris, France this coming weekend to keep him fit during sister Kim’s wedding festivities, reports TMZ.

The celebrity trainer told the website he is flying to the French capital to train Rob and his sister Khloe on Friday, Saturday, Sunday and Monday.
Gunnar said Rob was training five days a week, but scaled back to twice a week a fortnight ago because of his busy schedule.
‘[I’m] the gatekeeper of Rob’s workouts, not the gatekeeper of his life,’ said Gunnar.

Family first: Rob made a rare public appearance as he and mother Kris Jenner flew out for Los Angeles Airport on Sunday
Rob took a step back from public life last year amid reports he had sought professional help for emotional issues and weight struggles, but on Sunday the former reality star was seen at LAX with his mother Kris Jenner.
While the sock designer looked sullen as they arrived at the airport in Los Angeles, California, he obviously was not going to let anything stand in the way of him flying to France for Kim and Kanye West’s May 24 nuptials.
Until Sunday, Rob had not been seen in public since January.
Clearly happy to be with her son and glad to be flying out to the long awaited wedding, Kris smiled away as they pair made their way into the terminal.
Trying not to stand out too much, Rob dressed in a simple all-black ensemble of Nike sweatpants, a black T-shirt and carried a zip up jacket.

Keeping comfortable for the flight, the sock designer also wore a pair of white and yellow Nike sneakers and a blue baseball cap.
His mother also wore black but did not get the memo about dressing for comfort.
Instead the 58-year-old wore glamorous cowl neck long sleeved gown with black woven leather heels.
While wearing little jewellery, the Keeping Up With The Kardashians star added some serious expensive accessories namely a crocodile leather Hermes Birkin bag as well as some black designer sunglasses.
Kris looked relaxed despite there just being a few days until Kim ties the knot for the third time.
Perhaps she was feeling better having her only son by her side after a tough few months.
Last month several reports emerged suggesting that a depressed Rob had sought help for emotional and substance abuse issues.
Rob’s representative denied this was the case.

Ready to go: The reality star was dressed comfortably for the long haul flight to the French capital
Rob has stepped away from the reality show that made his family famous in this latest season and was noticeably absent from the recent filmed family vacation to Thailand.
Rob has noticeably struggled with his weight in the last year with reports suggesting he has gained around 100 pounds.
It is believed Rob’s struggles started after his split with singer Rita Ora, whom he accused of cheating on him.

Last month the star posted on his Twitter, then quickly removed the statement: ‘No one will ever understand how much it hurts.’
Hopefully Kim’s nuptials will give Rob something to be happy about – no matter where they say ‘I do’.
While the couple’s guests have been instructed to fly into Paris for a rehearsal dinner on May 23, it is understood the wedding will not actually happen in the city of love.
Kanye’s friend Ermanno Scervino confirmed to the MailOnline that the pair will marry in Italy in front of 200 guests at the famous Florentine landmark Forte Belvedere.

Elisa Di Lupo, a spokeswoman for the Mayor of Florence, also confirmed to the Associated Press the couple would wed in Florence next Saturday and revealed they had rented the imposing fort for 300,000 euros ($410,000). She said a Protestant minister will preside over the nuptials.
However E! News and TMZ have reported the couple will marry in Versailles, just outside of Paris.
Kim and Kanye visited the Palace of Versailles for an official tour in January – but their request to have their wedding at the venue was said to have been denied.
The circus never ends: Kim and her fiance Kanye West were seen strolling around Paris together on Monday.
