Thyroid Weight Loss and Diet Solutions By Mary Shomon | Reviewed by a board-certified physician Updated December 07, 2016 Print One of the most common complaints of people with thyroid disease is an inability to lose weight, despite a healthy diet and exercise. As a thyroid patient, you may feel like you are immune to the effects of even the most rigorous diet and exercise program, and some of you may even find yourself gaining weight, seemingly defying physics. The Thyroid LinkThe mechanism by which an underactive thyroid causes weight gain—or an inability to lose weight—isn't well understood, but it has to do in part with several key factors: Somewhat slower metabolismLowered energy, resulting in less movement and exerciseChanges to the way your body processes, stores, and burns off fat and glucoseTendency to hold on to fluid in tissuesFor some people, a thyroid condition is the reason for unsuccessful weight loss efforts. And we now know that, according to researchers, even slight shifts in thyroid function are linked to weight gain.If you are a thyroid patient frustrated by your efforts to lose weight, take a look at some of the approaches that you may find helpful in overcoming these factors—and get on the right path to healthy eating and successful weight loss.

You may discover that you don't lose weight unless your thyroid hormone replacement treatment is optimized. So, first step, partner with a knowledgeable practitioner and get optimal thyroid treatment.Other Hormones Play a Key RoleSome thyroid patients experience other hormonal shifts that can get in the way of successful weight loss. For example: Thyroid patients who are struggling with diet should learn about the impact of the hormones leptin and ghrelin on weight loss. Insulin resistance, also known as metabolic syndrome or pre-diabetes, is a factor that can affect your ability to lose weight. Your adrenal health, and in particular your production of the hormone cortisol, can have an impact on weight loss efforts. How Much and When You Eat MattersHow much, or how little, you eat and when you eat are both important factors that can affect successful weight loss for thyroid dieters. New studies show that changing your timing of eating and the length of breaks between meals may help enhance your metabolism and promote weight loss. And while we all know that calories often need to be cut for successful weight loss, they can be cut too much and slow metabolism to such a degree that a weight loss effort is sabotaged. Find out if you are eating enough calories to lose weight. Required BasicsWhatever diet or exercise plan you are following, there are two basic requirements that you should incorporate into your weight loss plan: Article Fiber: The Role in Weight Loss for Thyroid Patients Article Kale and Your Thyroid: What You Need to Know Get sufficient sleep.

In particular, incorporating more high-fiber foods into the diet may be part of a successful weight loss approach. Some other foods and supplements that may help, but have not necessarily been extensively studied as far as an impact on thyroid dieters include:Chia seedsCinnamonCoconut Oil GrapefruitConjugated Linoleic Acid (CLA) CarallumaHoodia GordoniiGreen TeaSabotaging Weight Loss It's important to know about the role of goitrogens for thyroid patients trying to lose weight. Goitrogens are healthy, cruciferous vegetables, like spinach, kale, and broccoli. When overconsumed, however, especially raw, they have the ability to slow down the thyroid. You can eat these vegetables in moderation, steamed or cooked, but overdoing it may work against your effort to lose weight. You also want to learn more about the potential concerns of overdoing it with soy-based foods. Not only is soy a goitrogen, but soy can also block the body's absorption of thyroid hormone. Movement, Exercise, and WorkoutsMovement—whether it be sports, exercise, or other forms of physical activity—is an important part of any successful weight loss program and is particularly important for thyroid patients.Start by learning how movement plays a role in boosting a slow metabolism. Movement can also help reduce fluid retention and bloating and make you feel more energetic. Not sure where to start? Check out this thyroid-friendly water workout.
