STG hope you will find the one thing you need and stick to it.
erebus I don't know why GR writes but what she does but I think the reason that GR is so down on using looks as a motivator is because it is quite a crap, negative one to use. The way it works (I THINK) is like this (for most of us) I look fat and unappealing and ugly and would look so much better if I were slim, and attractive and beautiful. So I will eat less and get slim. But eating less is hard so I can only keep going for a little while and when I hit a snag I might just fall off the wagon, THEN when I try and pick myself up the words I have in my head are "I am fat and ugly and unattractive....etc" rather than being a genuine motivator to some (most) of us these words are just something which COULD/MAY/MIGHT make one think "Oh why bother, what's the point, I'm not worth much anyway" ALL lies of course but that could be how it goes.
IF you are motivated to get fit and healthy, live a long life etc you can start with this, I am TRUELY beautiful, motivational and motivated, healthy and worth loving and caring for, my body is the home I carry around me all the time and it is wonderful, I must nourish it and care for it, love it and look after it because it is truly a miraculous wonderful place to be. Yes, bits of it are bigger or wobblier than I may like, but it is AMAZING and my main job is to care for it. To care for it with all the vigour that I care for my kid/s, hubby/significant other/older relatives etc!
It is about putting yourself back into the driving seat of your life for totally positive reasons and not allowing any down/negative/dirty talk!
The old name and shame approach to looking at fat photos and hating yourself for looking the way you look (I am NOT talking about you personally erebus but just people in general) is NO GOOD because at the end of the day if you do not value yourself you will not (probably not) want to look after yourself.
NOW that is not to say you or I would not look better with a bit less weight on BUT realistically how many times have you seen beautiful fat people and ugly skinny people! I know masses!
Beauty is not about how fat or thin you are BUT health really does go down as the scales go up (as long as people are not underweight of course).
So FOR ME the bottom line is that I must love myself, as I am but want to be healthy, rather than disliking myself as I am and wanting to change myself to fit into a better image.
As I have said before, in my head I am a size 10. I am pretty deluded!
We all need to do it in whatever way works for us so you must follow whatever works for you.
But as we get older and age we must love ourselves as we are. We may still want to dye our hair (I?ve dyed mine since about 30 anyway) and look nice etc but we must also want to look good for ourselves, not just for others, because if it is all about others that gives the power away. That others can make us feel good or crap about ourselves and if you feel crap about yourself then you may well splurge on cake to make yourself feel better rather than nourishing a body that you may dislike!
So it is very complex but I think that is what GR means. It is also what the New ID course I did does, I think, in one sense. They do not have pics of fat or skinny people to motivate the over or under eaters, because we are all loved by God and we are all beautiful but some of us are not treating ourselves nicely due to too much or too little food, or perhaps even the wrong kind of food.
Happy to discuss further and for people to disagree and IF looking good is a GENUINE motivator for anyone I would not want to spoil that! Hugs
