If you are 100+ pounds overweight and want to start losing weight, congratulations, this is a huge step 
in the right direction. Diet, movement and mental outlook all play a role in contributing to your weight loss success. Weight loss can be more complicated when a person has considerable weight to lose. Even if you are considering weight loss surgery or the gastric sleeve, these habits will help you keep the weight off over time.
Movement:
Not all workouts are created equal. Before you commit to a gym or a workout routine, it’s important to do your research. Exercise can be hard on your joints. Look for workouts and classes that are low intensity and low impact. You may even want to enlist the help of a personal trainer.
Even 30 minutes a day of exercise can be effective. Workouts in the water or on a spin bike are great workouts to try. You can even divide your workout into two 15-minute sessions. Once you’ve lost 10% of your body weight, you can up the intensity, working out longer and using weights.
Changing your diet:
Did you know that cutting 500 calories in your daily food intake can result in losing 1-2 pounds per week. Adding a lean protein and veggies to every meal can be effective way to get the nutrients your body needs. Your doctor can help determine your body’s exact caloric needs. Logging your food will also keep your nutrition on track.
Find a good support system:
Weight loss is most effective when you have a group of people to support you along the way. Accountability is extremely important, especially when you are changing your exercise and nutrition habits. A good support system can also help guard against depression and/or giving up when you are discouraged. Finding a therapist can also be helpful in keeping you on track.
Final thoughts — A person who is morbidly obese is also at risk for serious health complications so before you join a gym, start a new workout routine, or commit to a new nutrition plan always consult with your doctor first.
