Personally, I am a pretty big advocate of low carb and high fat diets.... so trying to stay natural with your foods, and then you can eat as much as you want as long as you are cutting out most of the bad stuff that might be high in sugars or high in unnatural kinds of oils or very processed foods that have a lot of artificial ingredients that interfere with your body's absorption of nutrients.

So maybe it depends upon what you are eating, because if you are starting to eat more, but you are eating better quality foods, even thinking about eating natural foods instead of processed, then you should still be advantaged, even if your appetite might have been getting higher based on your increasing levels of activity... without knowing more about the kinds of food you are eating, it might be more difficult to say what kinds of adjustments that you might want to make in regards to the kind of foods you are eating.   If you eat a lot of carbs then those have more likelihoods to keep you from losing weight.. especially processed carbs.. 

I do know that sometimes when I eat a lot of foods with dairy, I will get a bit sluggish in my work-outs, so sometimes I try to moderate my dairy, or maybe eat some of the dairy after I do my pushups rather than before, even though I am spreading my pushups through the whole day. so I am not completely able to do my push-ups before eating, even though I try to structure them a bit in that direction when possible.

Another decently important component is making sure that you are sleeping well, so then if you have the increased activities through your increased focus on daily exercising, then maybe that would also help you to sleep better too.. perhaps?.. so yeah 6-9 hours of good sleep helps your bodies recovery and likely its abilities to process nutrients better.
