Nutrition Advice?

Hey,
After being skinny all my life I have, in the last 3 years, slowly start to give birth to a mini GUT i've decided to stop being an lazy git and get fit. After about a week of reading up on nutrition and gym workouts and stuff, now im 3 weeks into this diet and exercise routine. Ive made it by watching youtube videos and reading blogs and looking websites, it fits in around work. Let me know what you think, i could be making a massive mistake nutrition or exercise wise and not know about it. Maybe i need to eat more?
