It's true. I jogged about 5-6 days a week for about 20-30 minutes a say a few years ago and the weight left me at a healthy tick. Naturally I could lose more with a better diet but I like eating so exercise it is.
Yep, if you were at stable weight before, it’s trivial amount of daily exercise to create a 500 kcal deficit which will have you drop 1 lbs /week. People who say exercise did nothing are either lying about amount or intensity of exercise or compensated with increased caloric intake
