Metabolism issues... any tips?

Hey everyone...

Quick question for you all...
I’ve been falling down a bit of a rabbit hole reading through these threads about weight loss and metabolism because, let's be real, I've got some extra weight to lose... I actually went to see my doctor and asked him to recommend a specific diet for me, since, you know, he's a medical professional and should probably know best... I've tried a ton of those "crash diets" before where I'd drop about 15 pounds pretty quickly, but of course, it always just comes right back after a while...
So, he ended up prescribing this diet—nothing crazy, it basically just boils down to counting calories, which means I have to weigh everything 😢— 🤷
and he mentioned that since he's been my physician for such a long time, he can tell my metabolism is incredibly sluggish, so he suggested I might want to try some supplements to give it a little kick, maybe by asking at a local CVS... That was my plan anyway, but I really wanted to get your take first and see if there's anything you guys would personally recommend...

Just to be clear, we're talking about exercise + dieting + supplements... not just popping pills and calling it a day...

Just looking at how long your doctor's appointment lasted isn't enough to decide if you have a super slow metabolism.
If you're basing that conclusion on your medical history or checkups, then suggesting someone just go grab some over-the-counter pills from a drugstore is, to put it mildly, totally unprofessional.

If my doctor acted like that, I’d take it as a total joke and a slap in the face.
I'd find a new one immediately! ☕
