What is your height and weight?
Cleaning up the diet will go a long way.
Are you doing any kind of cardio? A brisk 20min walk or (2)10min walk daily will help with mobilizing fat, better digestion and increasing your cardiovascular endurance.
If you have the starting strength program down then you have the basics. You can either keep doing that or IMO find a good upper/lower split and do upper one day and lower the other day.
If you want help with diet/training start a log and tag me. There are plenty on here willing to help if your willing to put in the work.
This is how my log looks. Your welcome to use it as a template.
