When it comes to losing weight there are many diet systems designed to help, but not all are created equal. The best is also largely determined by your individual needs. This report looks at three popular, but different diet systems to help you assess whi

What are the key differences between the three programs?

All three programs are dedicated to helping you be a healthy weight, but each goes about it in a distinctly different way. In a nutshell the difference between the three programs is as follows:

  • Nutrisystem supplies you with calorie controlled meals.
  • WeightWatchers provides you with support programs, but you provide our own meals.
  • MyFitnessPal  provides online tools to chart your food and exercise consumption. They also do not provide meals. 

The following is a more in depth look at what you get from each program:


MyFitnessPal is a free online program that helps you keep track of your weight loss goals. They provide the means for you to chart how many calories you are consuming and how many you are burning through exercise. So in essence they offer you an easy way to keep track of your DIY progress. They also offer some extra tools to help.

Signing up to MyFitnessPal simply involves filling in a short form, no credit card is required, because it really is a free program.

They ask for your height, weight, goal weight, activity level and how much exercise you are prepared to commit to each week. From this they provide your suggested fitness and nutrition goals as shown below. As you can see, they not only provide your recommended daily intake of calories, but suggest how many grams of protein, fat and carbs you should be consuming.

The example shown above is for someone maintaining their weight, but if you are trying to lose weight your projected weight loss per week and your expected weight loss in 5 weeks time (Presuming of course you stick to your goals) would be shown.

Your Food Diary

With your Food Diary, you can add what you eat as you go and they tally up how much you have consumed of your daily allowance and what you have left to consume. See the sample below. When it comes to adding foods, they have a great database that allows you to type in the food and search for it. You will find results for just about any type of food, including fast food chains. Then you specify the quantity consumed and they calculate the calories. This means you can quickly keep track of exactly where you are at.

Other things you can do with the food diary:

  • Store whole meals or recipes that you consume regularly in the database. Instead of having to add the individual components up all time.
  • Change what nutritional information they keep track of. For example, if you need to watch your cholesterol, you can add this to the nutrients tracked section and they will track this for you.
  • Choose between keeping your information private, public or shared with select friends if you want to connect with others for motivation.

Your exercise diary

With the exercise diary, shown below you can easily keep track of how many calories you are burning. As you can see the sample shows that the participant has performed 60 minutes of exercise out of their 180 minute goal for the week and they have burnt 265 of 770 calories.

When it comes to calculating the calories you have burnt exercising, they once again have a nifty database and calculator that works this out for you. You simply type in the exercise and the time performed and it returns your calories burnt. See the sample below.

Additional tools they offer:

  • See a report for your last 7, 30 or 90 days for your diet or exercise.
  • Enter your measurements at different times and then see a report of your progress.
  • Track your results on the go with free mobile app versions of their program. This is available for iPhone, iPad, Android, Windows and Blackberry devices.
  • Get, or create your own progress ticker. (as shown below)

  • Calculate your BMI or BMR with their calculators.
  • Connect with others in their online forum. This appears to be a supportive community. For example, people often post before and after pictures as they progress and many people congratulate them.

TamTastic says “I used MyFitnessPal to help me lose 135 lbs in a little over 16 months. The tools are very easy to use and the community is a wonderful support. I continue to use the site to keep myself on track during pregnancy as well."
