Yes. Dave Bautista said he sacrificed a lot of muscle while slimming down after gaining weight for Knock at the Cabin. He described reaching about 315 pounds, then later being around 240 pounds at 6 feet 4 inches. He has not publicly supplied a measurement showing exactly how much of that change was muscle rather than fat.

Why did Dave Bautista get so much bigger?

Bautista said he gained weight for his role in Knock at the Cabin. In a September 15, 2024 interview with Chris Van Vliet, he recalled reaching about 315 pounds quickly, eating “french fries and pancakes” to put on size. The director wanted him to look like “a great big guy,” rather than a powerlifter. Chris Van Vliet interview

He later called the process uncomfortable: “I put on an uncomfortable amount of weight, and it took me forever to shed it off.”

How did Bautista lose the weight?

In the same interview, Bautista said he was training hard and keeping his calories “pretty restricted.” He also said that as he trimmed down, he felt better and looked better beside other actors on camera. The Independent reported his September 2024 description of himself as 6 feet 4 inches tall and 240 pounds. The Independent

Calorie restriction and intermittent fasting

A March 27, 2025 account by Woman’s World said Bautista described capping his intake at approximately 2,500 calories per day and using intermittent fasting. That is a reported account of his personal approach, not a published medical plan or a prescription for others. Woman’s World

Jiu-jitsu and grappling

The same report described Bautista practicing jiu-jitsu and grappling for hours during filming, and said he used jiu-jitsu as a way to lose weight while pursuing a brown belt. Bautista was quoted saying, “I just shed about 50 more pounds.” The reporting supports grappling as part of his activity; it does not establish how much weight it accounted for.

How much muscle did he lose?

Bautista said he had “sacrificed a lot of muscle,” so the muscle-loss description comes from his own account. But the available reporting gives no DEXA scan, body-fat percentage, lean-mass measurement or verified breakdown of fat versus muscle. The roughly 315- and 240-pound figures describe different body weights; they cannot establish an exact amount of muscle lost.

What is Bautista doing now?

In a September 3, 2026 report, PC Gamer said Bautista had resumed weight training for the role of Kratos. The outlet reproduced his Instagram caption: “Third week into weight training again. 2 more months to get to where I need to be. Like ridin a bike! LFG!” That update reflects preparation for a specific role, not a claim that his earlier weight-loss approach is a standard training plan. PC Gamer

What Bautista’s transformation does—and does not—show

His account describes two different role-related phases: a quick bulk to appear imposing in Knock at the Cabin, followed by a longer effort to trim down through hard training and restricted calories. Jiu-jitsu and grappling were part of the activity he discussed. The sources do not establish a medically supervised protocol or show that someone else could reproduce the same outcome.
