While there are many ways to attempt to lose 20 pounds in two weeks, it may not be realistic or safe unless you are severely obese. In order to attempt to lose a safe and sustainable amount of weight quickly, you should eat properly, don't starve yourself, drink lots of water and get moving. It's also important to consult a physician before starting a diet program.
- Eat properly
Focus on filling up with vegetables. Try to avoid eating too many starchy or salty foods. Eat lean proteins, such as chicken breast, fish and egg whites.
- Eat when hungry
Eat when you are hungry, and don't try to go without food. Eating too little might cause your metabolism to slow down, and your body might begin to burn muscle in order to survive. You need muscle to help burn calories, so it is important to eat.
- Drink lots of water
Drink water instead of other beverages that have calories. Water fills you up and helps to minimize your appetite. It also helps maintain the electrolyte balance in your body, which keeps you from feeling fatigued.
- Get moving
Do a combination of cardiovascular and strength-training exercises for at least an hour each day. Try interval training, which is performing short bursts of high-intensity cardiovascular movements followed by a low-intensity, strength-training exercise.
