Although there are many ways to lose 20 pounds in four months, WebMD advises that the healthiest way to do so is by using proper diet and exercise techniques. All you need are healthy foods and a place to exercise, along with any necessary exercise equipment.
Eat a lot of vegetables
The high fiber and water content of vegetables make you feel full while containing fewer calories than other foods. This helps you eat more food while staying well within your caloric range for weight loss.
Drink lots of water
Water fills you up with zero calories, which prevents overeating. Also, if you routinely drink sugary soft drinks, replacing them with water reduces your calorie intake.
Throw away junk foods
The best way to avoid eating fattening foods is to remove the temptation by eliminating them from your house.
Don't skip meals
Skipping meals can lead to overeating at your next meal, which can lead to surplus calories and weight gain.
Add exercise to your day
To lose as much as 2 pounds a week, you need to burn 500 more calories than you consume for that week. An easy way to do this is to include exercise into your weight loss plan. For best results, combine cardio exercises with strength training.
