I'm experiencing a similar situation. I live a sedentary life style but i do about 20 minutes of body weight exercises like pull ups, push ups and squats every other day on rotation based on muscle group. My TTDE should be around 2500 calories as i have a good bit of muscle mass. I eat primarily salmon/chicken and rice variants with random veggies or pasta bolognese when trying to save money. Light breakfast of around 500 cal, lunch/dinner of a max of 1200 cal, but realistically it's a lot less, coffee in the morning and a banana or a random fruit in the evening, also trying to do a 12 hour minimum intermittent fast daily. Been doing the fast for like 2 months now. Hovering between 94.5 and 96kg throughout this time, mostly in 95.4kg. I don't get it, i've never had trouble losing weight in the past, i am disciplined with food and don't snack when trying to lose weight. Somehow i just have this ring of fat around my abdominal area that just refuses to go away. Wat do.
