Starting off with a 6 Week Challenge (1 stone)

Hi, I'm 5"2 105kg/231lbs. 20 years old from the UK. Looking for friends that can help me stay motivated. I feel like this is finally my year to do it. I want to be at a healthy weight before graduating university. I want to ultimately lose 30kg/66lbs. I'm curious to know if it is possible to lose a further 5kg/11lbs.

I'm a Fitbitter so:

2800 daily calorie burn
1500 daily calorie intake
7000 daily steps
2 fruit and veg a day (not the recommended but a start)

Should lose around a stone/ 14 lbs / 6kg
Starts from 06/05/2016. 42 days.

Please comment if you have any thoughts about this, advice, or if you're interested in joining a group I want to create for this. I want to be more active in the MFP community.
