Transitioning from weight loss to weight maintenance

My suggestion would be to work out how many cals a day you technically need to maintain your weight and start there.  2000 a day sounds like a good starting point but you probably need another 300-500 to account for the fact that you're very active.   If you choose slightly more energy-dense foods... e.g. oils, oily fish, nuts, dried fruit.... and if you increase your portion-sizes slightly you should be able to find an extra 300-500 cals no problem

And then it comes down to judgement and finding a balance.  If your weight stabilises on that amount of food, bingo... you've found a good balance.  If it keeps going down you need to add in some more.  If it goes up (but give your body 2 or 3 weeks to judge if it's just a temporary gain) then you may need to eat a little less.

Congrats in reaching your goal weight! I personally think you have a very healthy mindset, judging by the veggie policy and the fact that you don`t want to eliminate exercise from your daily routine. Therefore, I`m sure you will be successful at maintaining. I know it might seem scary at first, but once you get used to it it`s such a relief, really! Also, once maintaining, you should probably aim for intuitive eating, rather than counting calories and estimating/eyeballing, rather than measuring/weighing.

It`s all a matter of trial and error, but once you manage to find your personal balance, it`s one less thing to worry about, which is great. :)

Thanks, ily51, I appreciate your encouragement!  So far, I'm hanging right in there at 145 with slight fluctuations of a pound or two...I still find myself estimating calories but I'm not weighing or measuring portions.  I like the idea of "intuitive eating" and I like giving myself the freedom to eat what I want in reasonable portions.  I think I'm starting to find that balance, it feels great!
