Eating healthy is one thing. Having supplements is another.
You can eat healthy, with the right macros for your body, eat every 3-4 hours, and still, you might need supplements.
It depends always on your specific goal. And I say a specific goal because ok fat loss is a goal but not specific. How much fat loss do you want to have? You have to be micro-focused. Also, some nutrients its really difficult to find them in a normal portion of foods (again depending on your goal). Because you are a beginner I would recommend having BCAA's after your work out mixed with creatine for better recovery. Also, you might like to have casein protein before bed (this can work perfectly all night long, along with your body protein synthesis and recover the damaged muscle fibres better). Better recovery means more training.
Also sometimes by having let's say a protein shake (whey protein low calories) you can feel full and don't eat much. Always remember that calories-in < calories-out = fat loss (about 10-15 % fewer calories than you need is optimum)
Regarding your fat loss, you should consider building more muscles (fat burners) and doing some mixed cardio with hit workouts in your training week.
Another reason I am pro supplements is that it's more convenient to have them on the go and some times cheaper.
I wish you all the best for your fitness journey (it's hard and need dedications but its worth)
