I've recently reduced my calorie intake to 1500-1600 per day and the pounds have been dropping off the last two weeks. (Hate to know what my intake was before!!) I am happy about that. I was already lifting weights at the gym and added walking when I can fit it in. Problem is that I am so tired all of a sudden? Is it because I changed my dietary intake? And if anyone has had this experience I would love to know how long it takes before your body adjusted. I keep thinking it will adjust to the reduced calories and I'll feel more energy but it hasn't happened yet... Thanks!
