Yes, the important thing is that you can stick to it. You should jog (at the speed that you feel most comfortable). Suggested time is 30~60 minutes. It would be better if you knew how to do some warm-up exercises. As for eating, my own feeling is that it doesn't matter what you eat or how much you eat as long as you keep exercising. This is my personal experience (personal advice is to eat more). And those who say that thighs will get thicker, hehe, do you think it's that easy to get thicker? It is impossible to thicken without a lot of training for a long time. Finally, I want to say that being thin doesn't mean being in good shape. A good figure is convex and concave. Hehe, the last one is my personal opinion.
