IGN gave the episode a 9.2 of 10, indicating that it was "amazing". He wrote, "It's another terrific mix of character and comedy that is perfectly balanced," concluding that "
The Office remains one of the funniest, best written, best performed and one of the best shows of TV. Period." Nathan Rabin, writing for
The A.V. Club, graded the episode an "A−", giving particular praise to the development of the romance between Pam and Jim. "It was an episode full of big laughs and neat little character moments, as well as a number of gags rooted in camera placement.

Oscar Dahl of
BuddyTV lauded the episode, opining that it stayed true to the spirit of the show's previous four seasons. "
The Office is the unique comedy in which characters evolve, story-lines take seasons to play out and the mythology is never dispensed at the expense of the humor. Five season in, and tonight's premiere was every bit as funny as anything from the previous four. It's a testament to the writers and the actors, and their continued focus on staying the course, sticking to what makes The Office perhaps the best and most consistent all-around comedy."
Screen Junkies expressed hope for the season as a whole, stating "Everything that makes the show awesome is still there and firing on all cylinders, so I’m really looking forward to the rest of the season." "Weight Loss" was voted the second highest-rated episode out of 26 from the fifth season, according to an episode poll at the fansite
OfficeTally; the episode was rated 8.92 out of 10. ==References==
