Well done on a fantastic first week weight loss, that is incredible, well done you, you should be so proud of yourself!
I have been in therapy for a few years now and one of the things I have battled with is emotional eating. For most of my life I would go through massive binge eating where I would stack on 10-15kgs in a very short space of time, then I would starve myself and other patterns of bulimia. Learning to love myself no matter what (trust me, it has been a very hard road and I could write a book on it now I think) has been the key. Another great tool my therapist has me do is when I feel the need for a binge (so long as it is not due to being over hungry or depriving myself) is to close my eyes in a quiet room and gently ask myself why I want to eat. The key is to not think about it but trust the first thing that comes to your mind. For me it is usually worry, fear, stress about something in my life. It could be my job, a relationship, something I need to do that I am afraid of doing etc. Once you have realised the reason, try and either come up with a solution or talk yourself through it and ALWAYS being kind to yourself. Almost speaking to yourself like you would a small child. None of this tough love crap. Has worked very well for me. In 5 months of eating well and exercising to look after my body I have not once had a big binge though I have not unrealistically restricted myself either. In the past with any sort of weight loss plan I would go hell for leather during the week and overdo it with exercise and restricting my calories then on a Saturday or Sunday I would absolutely gorge myself stupid and that is NOT healthy.
The other thing that I have found good in terms of wanting to look after yourself is each meal you eat ask yourself that if you had a child that you were preparing a meal or snack for, is this something you would like to nourish your child with.
Keep going, you're doing great
