Step 1: Make a commitment
Start simply by making a commitment to yourself. Many people find it helpful to sign a written contract committing to the process.
Step 2: Take stock of where you are
Consider talking to your health care provider. He or she can evaluate your height, weight, and explore other weight-related risk factors you may have. Ask for a follow-up appointment to monitor changes in your weight or any related health conditions.
Step 3: Set realistic goals
Set some short-term goals and reward your efforts along the way. If your long-term goal is to lose 40 pounds and to control your high blood pressure, some short-term eating and physical activity goals might be to start eating breakfast, taking a 15 minute walk in the evenings, or having a salad or vegetable with supper.
Step 4: Identify resources for information and support
Find family members or friends who will support your weight loss efforts. Making lifestyle changes can feel easier when you have others you can talk to and rely on for support.
Step 5: Continually “check in” with yourself to monitor your progress
Revisit the goals you set for yourself (in Step 3) and evaluate your progress regularly. If you set a goal to walk each morning but are having trouble fitting it in before work, see if you can shift your work hours or if you can get your walk in at lunchtime or after work.
