Most people can improve the quality of the food they eat and lose weight. The first thing to do is switch from soft drinks to water. Soda should be a rare treat once or twice a month, not every day. Avoid fast food and eat home-cooked, well-balance meals focusing on a variety of vegetables as well as poultry, fish, and lean meats. Whole fruits are fine, and better than juices because they have more fiber you need. Don't fry food. Use healthier methods and healthy oils.
