When going on a weight loss plan it's important that you don't just change your diet by restricting your calories or starving yourself by eating once or twice per day.
In order to give yourself the best chance of melting away the body fat and keeping it off, you need to take on your body fat with a three-pronged attack.
A proper fat burning program includes:

• Proper Nutrition Plan
• Effective Weight Training Program
• The Right Cardio Exercise

While most people don't get nearly enough exercise, when they decide they want to lose weight they go too far the other direction.
One day they are eating everything in sight.
The next, they are starving themselves and doing two hours of aerobics daily.
This is a bad combination that is doomed to failure.
Eventually you'll want to incorporate high intensity interval training into your plan but if you haven't been exercising on a regular basis, you'll need to work up to it.
If you've been sitting on the couch for awhile, here's a five week phase to get you used to doing cardio and build up a base so you can start incorporating some serious fat burning interval training into your program and really kick start your fat burning into high gear.

• Week 1: Two 20 minute sessions
• Week 2: Two 25 minute sessions
• Week 3: Two 30 minute sessions
• Week 4: Three 30 minute sessions
• Week 5: Three 30 minute sessions (up your intensity from last week)

Remember, you should also be incorporating weight training as well starting with two full body workout sessions in weeks one through two and then three full body workout sessions with the weights in weeks four and five.
I've found that most people, when they don't track their heart rate during these cardio sessions, are actually working out at too low of an intensity level.
I recommend getting yourself a heart rate monitor watch for these workouts.
