I've been on general low carb, high protein and moderate amounts of fat diet for 3 weeks. I've been eating lots of salads with blue cheese or italian dressing, steak, chicken, eggs, tuna, bacon, eggs, cheese, peas, carrots, strawberries, broccoli, asparagus, and limited amounts of dry roasted peanuts. I have 2 cups of regular coffee each morning and 1 low carb beer or 1 glass of wine at night. I have eaten no sweets whatsoever in 3 weeks. I'm losing weight (14 lbs. so far) but I feel so tired! I was really tired the first week but kept on as I knew that was normal and I would feel better. I felt a little better the 2nd week (not much) but this week I have been as fatigued as ever. I'm taking the vitamins Dr. Atkins suggests and drinking water. I get a pretty good workout on the treadmill each morning for about 20 minutes (and its a real push as I'm so tired). I want to continue but don't know how long I can endure this extreme fatigue. Suggestions anyone??? Thanks for your help.
