Hi chenie, i just answered your other question. Now i see you are only 20 so its understandable that you may be finding it hard to manage your diet at this stage but the answers i gave still hold.
We are about the same height and i was about the same weight as you when i started - actually my doctor has me down at 85kg. I am currently at 68 kilos. I'm a lot older than you and have been through a number of ups and downs with weight over the years.
I have found it helps to consider that i have a sugar addiction. Of course there have been times when i eat too much of everything else as well but just quitting sugar has helps me get everything else under control. I was never really a huge savoury type junk food eater but if you eat too much of that stuff, then will have to be very careful over there too.
I have to say i find by working on improving the quality of what i eat, getting into a habit of cooking my own meals, keeping a food diary, my food has improved in taste and variety and quality and i feel better than ever. And i'm enjoying preparing my foods again.
A couple of books that have helped me recently are french women don't get fat and the don't' go hungry diet. I don't follow either way strictly but i have found what i learnt in those books both useful and worthwhile. The second one will teach you a few valuable lessons about nutrition, though i must say i am still a fan and consumer of full cream dairy. I do not think going low fat dairy is the right idea. And i think if one is consuming only a moderate amount of dairy, the amount of saturated fat in it, should not cause a problem.
you can read up on my blog link below. Its the second one, to see what i ate every day. You may think its not what you like to eat but it might give you some ideas about how much to eat and how to manage other difficulties. And you will see the sort of thing you need to do and how well it works because i have been there just ahead of you. My plan changes a little as i go along as does some of my thoughts and you can see a bit of how i deal with difficult periods.
In this weight loss game, if you want to be able to keep it off for ever, whatever strategy you choose, you have to think about if you can eat like this forever. But at the same time, if you need to know that you can't eat takeaways and lots of sweet things and avoid natural foods and keep off the weight forever. At some point along the path, we all have to change the way we eat and start choosing better foods that we like and learn how to prepare them.
And whatever exercise plan you follow, make it easy because too much is hard to sustain over the long term.
