Trying to Reduce Weight

I am trying to reduce my weight now for a better BMI. For a start, I have skipped lunch since 5 days ago, taking only small portions of fruits and water and exercising on the cross trainer in my condo unit. I am too lazy to get dressed and wear sports shoes to hit the gym downstairs in my condo, hence, prefer to exercise in private while watching telly preferably on a daily basis. For incentive, I get $5 for each meal I skipped from my spouse and $5 from dad for each KG that I shed. Currently I am 82 kg and hope to be the biggest loser as in the tv show showcasing the process of losing weight by all participants.
