First, if you are taking synthetic thyroxin pills, make sure you are taking a therapeutic dose. When was the last time your blood was tested for T3 and T4 levels?
Next, ask your doctor to refer you to a dietitian to help plan a healthy weight loss eating plan. That should include a moderate reduction in calories, no lower than 1200 per day and low-fat foods planned in 3 meals. Many foods are OK in moderation and very few foods such as sugars and high fat – high sugar sweets and desserts are omitted. Read the overweight category for more information.
Given your 50-pound goal, plan on reaching it in 5 to 10 months. You should also include regular exercise 30 -60 minutes, 3 to 5 times per week. If you don’t know where to start, ask your doctor to refer you to an exercise physiologist or call your local health club. Research has shown the most successful long-term weight loss occurs with moderate changes in eating habits and exercise.
