Fat should be about 30% of your diet. Where 20% is unsat fat and 10% is sat fat. A good general rule is 30% fat, 30% carbs (veggies and wheat are good sources), and 40% protein. Then you should focus on reducing you calorie intake. To do that you need to get an idea of how much you need to maintain your current weight, then reduce it by 500 calories. If that doesn’t work good enough reduce it another 200-300 calories. Do all this while trying to eat 5-6 small meals/day which will help get your metabolism going.
