should I expect weight loss to slow down?

im wondering the same thing. I started weight training 3 weeks ago and my scale went up 2 pounds. Im just going to put the scale away for now.

If you are not already doing strength training, then you should expect a slowdown while your muscles store extra water/glycogen/whatever because of their "new" activity.

After 2 or 3 weeks, you should see it pick up again. Use your measuring tape or some other way of measuring progress at this time.

I started Stronglifts 3 weeks ago. Similar to you, I'd lost about 10 pounds in a few weeks due to diet. The scale finally moved again yesterday/today. Don't worry about it. Measure in the meantime and see that your measurements are still going down.

Good luck! I did P90x a few years ago and loved it. Tony is an excellent motivator.

Yeah I think in general I like to see my measurements change more than the scale. So great idea to measure during this time and not care so much about the scale. And take before/after pics. When I am feeling unmotivated I look at before/after pics and that helps!

Fat loss itself will not slow down if you are following your calorie goals, so if the scale varies by a couple pounds it should not matter because water weight or muscle soreness will likely throw it off at first.

I plateaued at 105 for two months after I started weight training - it didn't feel like I was overeating but did not see any visible change for a while despite working to exhaustion almost every day. I suspect I was eating close to maintenance and didn't realize it. Adding in more cardio and cutting calories slightly worked wonders.

In my experience weight training causes some water retention for the first few months, and it also spikes the appetite. You can either choose to eat more and hopefully gain a little muscle mass, which will show beautifully when you return to a deficit - or stick hard to your calories and maintain the lean tissue you have while continuing to drop fat.
