Losing 100 pounds requires a strict diet and regular exercise. The number of calories you burn needs to be higher than the number of calories you consume. This process requires dedication and patience.
Eat small meals
Eat five small meals a day to keep your metabolism fast. Portions must be controlled so you do not consume too many calories.
Eat lean proteins
Eat meals that contain higher amounts of lean protein, such as skinless chicken, skinless turkey and egg whites. These foods contain nutrients you need to maintain muscle.
Reduce the amount of total carbohydrates in your diet. Replace simple carbohydrates with complex carbohydrates, such as grains. Grains provide the energy you need for daily activities and exercise. Eliminate as much sugar as possible.
Add at least 20 minutes of aerobic exercise to your daily routine. Exercise six times a week. To stay on track with your exercise schedule, mark your progress in a notebook or computer spreadsheet.
Drink plenty of water
Eliminate soda and juice from your diet, as these drinks contain unwanted calories. Drink at least 64 ounces of water daily to keep your body functioning properly. Water helps you feel full so you do not consume extra calories.
Stay well rested
Allow your body to rest and recover once a week so you are physically and mentally prepared for the next week of exercise.
