I'm at 172.6, down another 0.4 lbs (though that's within the margin of error for my scale) today for a total loss of 1.4 lbs out of a goal of 5. I was hoping for a bigger loss this week and I'm discouraged. Thought about throwing in the towel this morning, but I'm really interested in collecting the data on this. I averaged 1469 calories (1236-1772) and 10,280 steps a day (3773-15,678) for the week. I know about 1200-1400 calories is weight loss range for me and 1400-1600 is maintenance. I'm not surprised by the lack of progress from a data perspective, but based on my hunger levels I would have expected more.
Our data are so comparable, though I've lost a bit more this month (could be a lucky fluke). I started at 175.5 a couple of days before 3/1 and was at 171.3 this morning. So 4.2 pounds in a touch more than 3 weeks. Average calories are a little lower than yours (1357), steps a bit lower (5309). Some of those steps are cardio (dance), plus averaging 20 flights of stairs a day. I shoot for a 40-30-30 but probably end up more like 40-35-25. It's a large amount of fat (full dairy like greek yogurt, avocado, coconut oil, nuts) and I find that occasionally I have to eat extra at the end of the day because I'm only at 1000 and pretty satisfied. I also haven't been drinking at all for five weeks, which made dropping calories (and probably pounds) much easier.
I've been pretty obsessive about the tracking for this challenge--weighing and measuring and counting everything. Eating the same foods frequently helps make that easier (e.g., oatmeal with protein powder and a banana almost every morning). I do the think the high fat content helps prevent the crazy hunger.
I think it also makes a big difference where you are in your weight loss process. I've really begun in earnest with this challenge, so I was ambitious with my goal knowing it's always easier the first several weeks. In April I'll pick 4 pounds, because 1# a week is more realistic based on past experience.
And, ultimately down is down, right? It's a marathon not a sprint.
