Trying to transform

I'm trying to for once in my life get a beach body haha. I'm from Georgia and it's something I've never had. I'm 5'10, and just hit 229lbs! At the beginning of the year I was 254. However, I've only been working out and doing cardio the past month and have lost around 7 or 8lbs since. I have a friend who is a bodybuilder and competes in comps and he's given a little advice such as dieting, mainly fats, cals, sugar and salt and carbs, but mainly fats and sugar he said and so far it's been good. Anyways, this app wants me to take in 1500 cals a day, after spending 2hrs at the gym and everything, is that enough?
