TL;DR go walk and eat good food
It's dumb, as a person who was (and still is a bit) overweight, there is no short cut. Track your food and exercise, calories in and calories out. It's math and science, lots of protein means you build more muscle and then you burn more calories faster. I lost 70+ lbs just by eating more protein and less carbs, walking, and doing a little weight lifting. I quit walking and ate crappier and put on some weight, now I'm getting back in to the swing of things and am happier about life.
Let us not forget about people shitting themselves because of the ozempic and wegovy. People don't learn how to eat with surgeries and these drugs, so they're always sick and malnourished because they're not absorbing the nutrients they need from food and won't/can't take necessary supplements. I have several people in my life who have done gastric bypass surgery and ones who are on the drugs none are healthy except the one person who watches what she eats and walks every day (but she barely has any hair and it is dry and unhealthy).
This is a passion issue of mine in case you couldn't tell 😂. Sorry for the rant 🫂💜.
