This gets cited here weekly, usually second-hand, so it is worth setting out what it does and does not establish.
Training does two things here and only one of them is on the scale. It protects lean mass — which is the reason to do it — and it contributes modestly to the deficit, which is the reason people start and then quit when the arithmetic disappoints them. In a deep deficit, resistance work is the priority and high-volume cardio competes with recovery.
Where I think it is weakest: the completion rate deserves as much attention as the headline, because a large effect among those who finished is a different claim from a large effect among those enrolled.
So the question, as narrowly as I can put it: what training is actually for during a large deficit, because framing it as calorie burn sets people up to quit when the arithmetic disappoints them. I have searched first, so if this is covered somewhere point me at it and I will read it.
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

Exercise transformation with training: went from barely able to walk a block to completing a 10K last weekend.
My fitness journey alongside GLP-1 therapy:
- Month 1-2: Walking 15 min/day
- Month 3-4: Walking 30-45 min, started bodyweight exercises
- Month 5-6: Joined a gym, started resistance training
- Month 7+: Running, lifting heavy, swimming for fun
The weight loss made movement possible. The movement made more weight loss possible. Virtuous cycle in action.

Pet owner bonus of training: my dog is also losing weight because we're walking 2-3x more than before. His vet is thrilled. 🐕
We went from a 5-minute shuffle around the block to 30-minute walks through the neighborhood. He's more energetic, I'm more energetic, and we're both healthier.
Get a dog. Or borrow one. Walking a dog is the best low-impact exercise motivation that exists. They never let you skip a walk. 🐾

Gym confidence after training weight loss: walked into a gym for the first time in 12 years yesterday. Was terrified. But you know what? Nobody stared. Nobody judged. Everyone was focused on their own workout.
Started with 20 minutes on the treadmill and some machine-based resistance exercises. Nothing fancy. But I DID IT. And I'll go back tomorrow.
To anyone too intimidated to start: the hardest rep is walking through the door. Everything after that is just movement. 💪
