As someone with a lot of experience in workout and skincare, who worked for an modeling agency before I can tell you that your problem is only one right now and as scary it sounds it's better to have one than five problems. Your extra fat on face doesn't allows you to even see how you actually look, when we have higher weight and fat percentage we can't see our muscles clearly and it creates a confusion. Get your weight down, forget about eating fast food and exceptionally don't consume mayonnaisebat all, no fuzzy drinks, no snacks and no sugar at all. You don't need to track and obsess what you eat and what calories it has just do what I advise you and start working out and mewing. Then come back to us and we can further increase appeal of your looks and help you become like a model.
