It's not as hard as you think to lose weight and keep it off.
First you have to change your mindset, and not think of exercise as a burden. If you say to yourself, "I want to be healthy, have more energy, lose weight, tone up", then you are on the right path.
Incorporate eating 5-6 small meals each day, exercise most days of the week for 45-60 minutes (resistance training, cardio), and you are well on your way to a healthy lifesyle.
Stop making excuses as to why you can't do these things, and just get it done. Start out slow, and build yourself up, in time you will get stronger.
Make one small change daily until you get into the habit.
