<human>: Can you succinctly summarize the text in 1-3 sentences?

For the past month and a half to two months I have been in full on diet/workout/weight loss mode. I have already lost just shy of 20 pounds, and while I still have about 15-20 left to go, I can't help but look to the future. 

In order to lose weight I have put myself on the Paleo Diet after seeing my dad switched his diet and saw a lot of weight loss at the age of 60. I don't count calories, I just eat normal portions, until I am full, and snack only when I am hungry. Meat and veggies for every main meal, and a handful of nuts or some fruit as a snack. I also am working out using the bike and going for runs about 3 times a week. 

I guess my question is, I am a little worried about how to actually start maintaining my weight when I get down to my goal weight. I have been eating this way about 80% since the start, and for the past 3 weeks been eating strictly paleo. I have been losing weight steadily over that time, but I am just not really sure how to really up my caloric intake without completely changing my diet or feel like I am over eating. I always just stop eating when I am full and snacks usually keep me from being hungry throughout the day. When I get down to my goal weight I just dont want to keep losing weight and have it become unhealthy. I am really enjoying my new change of lifestyle and would like not to change it too much if at all possible.

So I guess
<bot>: When all is said and done, does anyone have any good tips to increase caloric intake to maintain weight without going overboard and eating too much/unhealthy again?
