Don't drop your calories too rapidly. For a male, 1800cal may be best as not to totally shock your body. May I suggest you arm yourself with knowledge do the research on proper eating like maybe Eat to Live or The End of Diet, by Dr. Fuhrman. Try <http://iifym.com/iifym-calculator/> to plug in your 1800cal and see what that means for protein|fat|carbs. And, finally, make sure you first cut out refined, highly-processed foods and think "whole foods" (even low-fat and low-sugar processed items can trigger hunger and stimulate the appetite)! I'm no expert, but a little research and knowledge can go a long way toward helping you reach your goals. Good luck! :D
