People with hypothyroidism can often lose or manage weight through dietary changes, physical activity, and stress reduction.
Hypothyroidism occurs when the thyroid gland does not produce enough hormones.
While a reduction in metabolism can make weight loss difficult, it is not impossible. Steps to managing weight often involve:
- lifestyle changes such as:
- physical activity
- stress management
- treatment for the underlying cause
- hormone level checks
This article reviews weight and hypothyroidism and the changes people can make to help manage and lose weight with hypothyroidism.
Serious cases of hypothyroidism can lead to an estimated
A person may also gain about 5–10 pounds directly due to hypothyroidism. This weight gain mainly comes from water and salt retention, but it should clear once treatment or lifestyle changes start.
Read on for the ways a person can lose weight with hypothyroidism.
Dietary changes may help with weight management. However, a person with hypothyroidism should consider how certain foods may affect their thyroid and include or exclude them from their diet.
Currently, there is no specialized diet for hypothyroidism. However, the
- certain foods may interfere with medications
- foods with certain nutrients may help maintain thyroid function, such as:
- some foods may contribute to a diminished thyroid function
Hypothyroidism may occur due to much or too little iodine intake. The thyroid needs a certain amount of iodine to function properly.
However, people with Hashimoto’s thyroiditis, an autoimmune disorder that is a common cause of hypothyroidism, or other autoimmune disorders affecting the thyroid may negatively react to foods and supplements containing large amounts of iodine. This could lead to diminished thyroid function.
A person should focus on following a balanced diet and consuming foods such as:
To help a person lose weight and avoid exacerbating their hypothyroidism symptoms, a person can follow a balanced diet and limit foods that are:
- high fat
- simple carbohydrates like sugar
A food journal may help a person understand the foods they are eating and be more mindful of what they consume each day. This is a form of mindful eating.
The benefits of food journaling can include helping a person:
- determine if they are eating too little or too much each day
- remember what they consumed each day
- see when they get hungry each day and adjust their eating habits
- determine if they are eating due to boredom instead of hunger
- achieve their goal
However, journaling may not be for everyone. A person should discuss this method with a doctor or nutritionist before trialing it.
Increased activity can work in conjunction with improvements to diet. A person needs to be more active to lose weight or maintain it.
Researchers in a 2015 study attributed improvements in thyroid function with decreased weight due to regular exercise. They observed these effects mostly in people with hypothyroidism.
At a minimum, a person should aim to get at least
In addition to cardio workouts, a person should aim to participate in resistance training
- lifting weights
- using exercise bands
- doing bodyweight exercises, such as pushups or pullups
- using kettlebells
However, before starting any new activity or exercise program, a person should consider talking with a doctor or physical therapist to discuss suitable levels of exercise for them.
While the specific links between stress and hypothyroidism are not conclusive, finding ways to manage stress may help a person lose weight and maintain weight loss.
Though people may respond differently to interventions, some ways to reduce stress include:
- psychotherapy (talk therapy) or other therapeutic approaches
- regular exercise
- breathing techniques
- practicing mindfulness and meditation
- avoiding stressors whenever possible
To treat hypothyroidism, a doctor will
A doctor may also recommend treatment to address an underlying cause of the condition.
The NIDDK suggests several factors can cause hypothyroidism, such as:
- Hashimoto’s thyroiditis
- radiation near the thyroid
- congenital causes
- certain medications
A person should follow all instructions from a doctor regarding when and how to take the medication and adhere to any other treatment methods needed.
By addressing hypothyroidism, a person may lose some weight through treatment. A person can lose a small amount of weight when starting hormone medications, but it is generally less than 10% from medication alone, meaning a person will still need other methods to help lose weight.
As part of treatment, a person should have their hormone levels checked regularly. This can help ensure that treatment is effective for the person.
Typically, a doctor checks a person’s blood work every
Losing weight safely generally involves a combination of lifestyle changes, including increased exercise and changes to diet.
People interested in losing weight may want to check out support programs for further guidance. For example, Weight Watchers, rebranded as WW, provides support, meal plans, and other advice on losing weight.
