I avg between 1800 & 2000cal per day with avg about 30g carbs a day and I have been losing a steady 2lbs per week. My activity level is moderate with added exercise at least a few times a week.

My calories are from 1320-1450

I eat between 2400 - 3000 calories for 4 days.
Then I eat 1400 - 1600 calories for the next 3 days.
During those last 3 days is when I always get my weight loss for the week, Average 3 lbs per week.
I just never let my body get use to being on a steady amount of calories.

This way of jogging my calories reminds me a man who fell off a 20 story building.
As he was falling by the open windows of the building. The people inside heard him say, So far so good....So far so good.
