Pet owner bonus of training: my dog is also losing weight because we're walking 2-3x more than before.

Exercise transformation with training: went from barely able to walk a block to completing a half marathon last Saturday.

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, cycling for fun

The weight loss made movement possible. The movement made more weight loss possible. Virtuous cycle in action.

One concrete data point for the thread. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Adding the part of the answer the thread has not reached. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.

A narrower follow-up, since the general answer is now clear:

What did you change at the same time, and can you separate the two now?

Closing the loop on my own question.

Reporting back for the archive rather than for the thread: I did the narrow version of what was suggested, gave it the full interval, and it settled. Posting it because threads without a follow-up are half a thread.
