Can anyone help with diet pls ?

^This. You don't "have to" eat vegetables. Salad isn't necessarily low cal anyway. Salad can be low cal.

Veggies are recommended by many because they are relatively high volume, and low calorie. When someone wants to bulk up serving sizes, veggies can be a good tool.

Protein, fiber and fat are filling components. But it's not the same combination for everyone. If fiber is filling for you, then look to whole grains and fruit. A bit more calorie dense (on average) but do what you can stick to. Smaller portions of your current diet will work.
