Jennifer Aniston Highlighting Muscles In Underwear Is 'Severely Limiting Food Intake'

Jennifer Aniston has been criticized for her latest body flaunting. Earlier this week, the actress stripped down to a black spandex look, showcasing her incredible abs, in an Instagram video promoting the Pvolve fitness brand she fronts. Displaying her sculpted arms, shoulders, and rock-hard torso in a two-piece look with visible undies, Jen reminded fans that she's fitter than ever at 56, but some seemed to think that she might not be eating properly. Haters shaded the sitcom star for having tons of money, "private chefs," and the "best trainers," but others pointed the finger at Jen's weight. When fans reacted, one claimed that Jen is "severely limiting" her "food intake."

Scroll for all the photos. The above one was shared by Chris McMillian, long-term makeup artist to Jen.

Lifting her arms above her head while flaunting her insane six-pack, Jen showed how little of her self-confessed "cheat food" days go to her waistline. Dropping jaws in a tight black sports bra and sporty pants, the ex to Brad Pitt wore her sweats low-slung, flashing sporty black briefs while drawing the eye to her killer hips.

Showcasing her sculpted shoulders while looking flawless with her highlighted locks worn down, Jen exuded natural glow vibes, although she hadn't scrimped on the makeup team, as she rocked a sun-kissed look. "Strength isn't just fitness, it's the ultimate anti-aging secret. And Jennifer Aniston is doubling down," Pvolve said in a statement to accompany its latest campaign. Jen had shared a fitness mash-up video on her Instagram, one showing her balancing, stretching, and using resistance equipment.

Comments quickly poured in as The Daily Mail's users reacted to Jen's ripped body.

"Any celebrity with enough money for the surgery, training, and meds she's getting could look as ripped or plumped as they like," one angry user replied. Over 300 fans agreed when another user said that Jen was on the "childless cigarette diet." Also bringing up Jen's weight, a third wrote: "She stays a size two the same way all other actresses do by severely limiting their food intake!" Jen has never confirmed restricting her eating. In fact, she's admitted to loving cheat days filled with Mexican food, pizza, and burgers.

Jennifer Aniston put her toned physique on display earlier this year, making instant headlines for wowing in this sexy LBD.

Going hell for leather in a shoulder-baring look in NYC, she modeled her dress and heels as part of her promo tour for The Morning Show, which recently began its fourth season. Jen was mocked for her dress, but there was no denying that she was in the best shape ever.
