[edit] Steps

1. 

   A delicious watermelon!
   Eat more! Don't be fooled because the article is referring to more of healthy, low-fat foods rather than junk food. Junk food can range from burgers to those cookies that you always bought! Adding a lot of vegetables and fruits to your diet will help you. Also, drinking bouillon, a Haitian soup, made with filtered water will help you feel full.
2.

   Exercise every day! This could be the most difficult step to follow. But what you can do is actually start slowly then steady increase the amount of exercise. For example, today you will walk for 10 minutes, repeat this for the whole week. For the next week, double your workload. You may get leaner that way! The important thing is to get your heart rate up and start, now!
3. Feed your temptations once in a while. Go ahead and have that donut or slice of pizza, but before you do, drink a few glasses of water and eat a bowl of raw veggies such as cucumbers, celery, carrots, and tomatoes. They will fill you up and you will have very little room to eat the "junk" food.
4. 

   Scrumptious!
   Consume things that have no calories. There are two things you eat and drink that contain no calories: water and fiber. The more of these you get into your diet, the better off you will be. For example, you can eat a pound of mixed salad greens with assorted raw vegetables (carrots, red cabbage, celery, broccoli, onion, etc.) with a low or no-calorie salad dressing and only have eaten 100-150 calories. This is because of the high water and fiber content of the salad and low calorie dressing.
5. Take broth-based soups. They are a relatively low in calories. A commerically-available ready to eat "chicken and stars" soup may only have 80 calories for 1 serving, much less than diet "meal shakes" or nutrition bars.
6. 

   These may help you.
   Practice good eating habits. Always use utensils and sit at the table. This stops you from eating precariously. Eating with your hands will mean that you take in more food in one scoop. Don't forget to eat slowly and stop when you're full. Similar to the above step, if you can't stop, drink up! Maybe your body is thirsty and hungry no more! Also, you can do any other chores (other than eating). For instance, go shopping, or play badminton with your friend, or play games on the computer!
7. Spread out your diet! Eat more small chunks of meals, rather than 3 big meals. If you eat 100-150 calories or so every two hours, your body stays in a higher-metabolism digesting mode. This allows you to burn more calories than eating just 3 meals a day.

[edit] Tips

• Avoid calorie dense, unhealthy food. Unhealthy food is food which contains calories, but little nutritional value. These calories are called "empty calories." You will probably be best served if you also avoid foods that would contain empty calories if they were not fortified with vitamin C (like some gummy bears) or calcium (like some cookies). Fortification with vitamins doesn't always make unhealthy food healthy.
• Try to do a little bit at a time until you get used to it.
• Get a friend to follow the diet with you. Sometimes, when following a diet by yourself, you'll break the rules because it's just you. But following it with a friend, you have a partner who will help keep you on track and responsible.
• Expect to cheat or binge once in a while. (A word of caution: if you're binging more than once or twice a month, consider a different approach to your weight loss goals.) Don't despair when you realize you've strayed from your goals. It took you many years to achieve your current weight, and it will take time to achieve your new weight and size goal.

[edit] Warnings

• You have to exercise and eat healthier, otherwise you may not notice any improvement and—even worse—you may gain weight.
• If you need to lose more than 10% of your body weight, consult with your primary-care physician before beginning any weight loss plan.
• Try to limit water consumption to 10 glasses per day. People can drink far more water than necessary while exercising, however, putting them at risk of water intoxication. (Water intoxication is incredibly rare, and easy to avoid by making sure to consume electrolytes <even just salt> along with the large amounts of water)
