I totally agree with CKaiSmile.
There is really no substitute for eating healthy and regular exercise.
A lot of people are simply making excuses of work, friends and family committment. Though those are important, nothing
beats your health.
Because if you are sick, you can't do many things and ended up being looked after by others. From my experiences, most
people - out of pride - refused to be in that situation.
If you have to, get a personal trainer to help you. However there are pros and cons as well. The pros you have someone to account to whether or not you get results. The cons are you have to restrict yourself from eating your favourite foods everyday for the next 3-4 months to see any significant results.
Unless someone can come up with a better alternative on how to lose weight without compromising what you like to eat or drink.
