I've been dieting for just a little over two months, right now I'm going at about 1500 a day with two days a week at work I'll do higher calories. Like today I ate two foot long roasted chicken honey oat sandwhiches from Subway and I was nothing but a blur at work I was going so fast. But just eating 1500 cals a day I still feel full and have energy. Just when I eat higher calories I go insane with energy. Almost 220, started at 255 and boy I can tell a difference.
