@j_g94 You've probably heard this before, but I'll reiterate jt... Inputs vs outputs. Working out consistently gives you a boost in how much energy you're spending/outputting. If you diet along with that and can stay consistent you'll slowly widdle away at your body fat.
On the other hand if you start eating more when you start working out, fat may not change, but your muscles underneath may get bigger, and show through more, but again if you're spending the same amount you input, why would your body use stored energy.
I highly suggest tracking calories if you have never tried it. MyFitnessPal is the app I used, I think I got a free subscription and it lets you scan barcodes and look up whatever you're eating in their big data base of food. Yes it's not going to be perfect, but will give you a rough estimate of what you're actually putting in yourself.
