Higher protein, lower carbs (or time your carbs for after exercise) and low to medium good fats (nuts, advocados, fish etc).
If you exercise and eat a higher protein diet (lean meats, pulses, dairy, eggs etc) you will build more muscle and raise your metabolic rate leading to further weight loss. Don't calorie restrict too much as it is counter productive.
I generally eat: eggs for breakfast (omlette or scrambled eggs/ ham) with a piece of fruit for breakfast, nuts and seeds for snack, turkey rice and spinach for lunch and then meat and veg, or fish veg and potatoes etc. I don't restrict myself, still have some chocolate if I fancy it etc. I eat pasta, bread etc but its balanced. Fresh greek yoghurt, cottage cheese- all sources of protein.
Have you heard of Joe Wicks aka Body Coach, its a great plan for people wanting to lose weight and get fitter. There are loads of example plans out there though. Once it becomes a routine its easy (and my kids eat like me, but do have cereals etc sometimes in stead. They love eggs for breakfast and scrambled are so quick.
And if you can, prep in bulk so its easier.
