Advice on losing weight

I’m looking to lose some belly fat but I have no idea how to start. I only eat twice a day anyway so I’m not sure how I’ve gained weight, guess it may be due to not being very active.

I just want to lose belly fat and also fat from my face but obviously you can’t directly lose face fat.

My current diet is eating breakfast around 8 and if i don’t have work I eat breakfast at 11. Then rest of the day I drink water and then 6 I have dinner.

I have no idea how to start losing weight, should I go gym too? But I don’t know what to do at the gym to loose the belly fat cardio or weight training? And in what order?

Please help
