So I've been doing everything right (weighing everything I eat and logging it correctly, sticking to a calorie deficit) and my weight hasn't budged - in fact, it's gone up a tiny bit (by 0.2 kg). The thing is, I'm aware that I've not been doing this long (only a few days, although I'm not new to calorie counting or MFP), and thus it's most likely just water weight fluctuations (especially since I've started strength training recently and it's possible I'm retaining water because of that). However, despite the fact that I know it's probably just normal fluctuations, and that I need to stick to this for a much longer period of time to see real changes, I can't help but feel very low. All the logic in the world doesn't really help the fact that I saw a higher weight on the scale this morning and now feel unhappy/bad about myself.
What I'm asking is, for those of you who also struggle with this, how do you cope? What do you do to not let fluctuations in weight affect your mood?
