My opinion: Calories matter. After losing about 40 lbs on LC, I low-carbed for about a year staying at one weight (~255 +/-5), not paying attention to calories. I finally tired of the wait (pun intended) and started counting calories, too.

I must say the dietary change was not the only alteration to my lifestyle: I began walking one or two miles 4x per week (normally, I'm rather sedentary). Combine the caloric restriction (not starvation) with the walking and the results have been drastic: In ten weeks I've lost 29 pounds. Now at 230, I've decided to go below my original target weight of 210 and shoot for 190.

Staying true to a L/C lifestyle, I've decided food is simply a requirement for life, not life itself. My new motto is four simple words: Eat less, walk more.

Over the last 3 weeks I averaged 1600cal, 45 netcarbs and I exercise 4days per week. I lost 1lb every week. I have hypoglycemia and suffer if I eat lower then 1400, hopefully this wol will fix that! I only count calories but I do not limit them at all.

I voted that I average 1600-1800 calories per day as indicated by Fitday, however, I do not make a conscious effort to watch my calories. My first goal is to feel good and the second is to lose weight. I am losing slowly but I am losing. I am 58 years old and stand 5'10" tall. My ultimate goal goal is 150 which theoritically require a BMR of 1800 calories per day.
