how can i create a week plan to raise my metabolism and lose weight?
should i bike ride one day, walk the next, run the next then go back to biking or something..
please help.

First of all, at 53 kg, do you really need to lose weight??? I am 58kg and I am swimming in Australian size 8!! (American size 4, I think??)
If you really do need to, the weights idea is a good one. As a female, you won't bulk up, you will just become toned and you don't need to overdo it. This will challenge your body in a different way to cardio and will raise your metabolism. It sounds as if your body has become too used to what it is doing now and needs to be challenged.
But seriously, think about it - why do you need to lose more? Why aren't you happy being a weight most women would love to be?

they are bodybuilders that will help you create a workout plan that you can easily do at home.
they will advice you on how long you should walk/run/ride bike.
see, as your body gets used to something ,if you dont speed things up, or change the routine..your body gets used to it, which means whatever you do, it will have no effect on your body.
However if you change routine..it will keep your body guessing, which means you will be really working out.
these guys are great, they will be able to help you, so send them an email with your problem.

If you weigh around 53kg you sound healthy to me and perhaps this is your natural weight. Why do yo need to lose more?

You won't believe this..I just asked the same question several days ago. The best advice I got...It actually worked.... Pig out for two days with no exercise and your body won't think it's starving itself anymore. Then resume your normal diet and exercise and you will start to loose weight again!!!
