When you’re battling a thyroid condition or imbalance, trying to lose weight can feel like a cruel joke. You try to eat well, and you take your thyroid medication. But nothing seems to help. Losing weight and keeping it off can be a struggle.
But if you break down the process into small steps, and tick each box as you go, weight loss comes much easier. This article covers the 6 fundamental steps required to successfully lose weight with an under-active thyroid.
If your medication is not helping to correct TSH and thyroid hormone levels, as well as relieve symptoms, then weight loss goes from difficult to impossible.
Work with your health care provider to determine what type of medication is better for you, and also to find the optimal dose required. While Levothyroxine is on average more effective, Desiccated Thyroid is reportedly much better tolerated.
There is no difference between taking your thyroid hormone meds in the morning vs evening. Choose whatever is easier for you to have it on a fasting stomach
Carbohydrates are not inherently bad for you. That is, they do not make you fat or sick on their own. It always comes back to total calories consumed.
That said, carbs in the form of added sugars and highly refined starches are unhealthy and unnecessary. They offer almost zero nutritional benefit (known as “empty calories”) and make up a large portion of the excess calories we consume.
In fact, the average American adult’s consumption of added sugar increased by more than 30% in the last 30 years, with children consuming approximately 20% more. This was illustrated below by Obesity.org.
Fortunately those numbers have began to reverse; a trend that needs to continue. Nevertheless, cutting back on added sugar is still the most simple and direct way to cut out excess “empty” calories.
This is done by limiting intake of junk foods, flavoured drinks (including juice), alcohol, white bread, most cereals and muesli bars, and a good portion of packaged food in your supermarket’s “health food” aisle. That includes gluten-free junk food… it’s still junk food.
Now it’s unrealistic (and unfair) to expect yourself to completely avoid added sugar every day of the year. But you need to begin taking actionable steps that help you cut back and form healthier habits.
Start by not having junk foods at home, or at least keep them out of sight in a cupboard you never use.
If you want to lose weight with an underactive thyroid, these should be the foundation of almost every meal you make, and plated first when serving.
There are 2 main reasons for this:
1. Protein is paramount for weight loss
The main benefit of protein is that it’s much more satiating than both fat and carbs. That is, it has a unique ability to reduce appetite and therefore your overall caloric intake too.
Studies show high protein diets may also reduce obsessive thoughts about food by 60% and cut desire for late-night snacks by half.
Foods high in protein include meat, seafood, eggs, nuts, legumes (beans) and dairy.
Protein is also the muscle-building nutrient, so a high protein diet complements regular exercise.
2. Vegetables provide most vitamins, minerals and other micronutrients
The nutrient-density of meals is even more important for those with hypothyroidism and other autoimmune diseases, where nutrient absorption and deficiency are more common.
Emphasis goes to green leafy vegetables, mushrooms and cruciferous vegetables like broccoli, cauliflower and cabbage.
Veggies are also our greatest source of fibre, a nutrient that feeds the healthy bacteria in our gut. Studies show that long-term low fibre intake will completely throw out the balance of your gut bacteria; the effects on the gut health of mice was irreversible.
As a general guide, the protein portion of your meal should be the size of your palm, and salad/vegetables the size of your hand. This would leave about 1/4 or less of your plate for carbs (such as rice or potato or pasta).
Selenium and zinc are two nutrients directly involved in thyroid function.
It is critical that your diet contains adequate quantities in order to optimise thyroid hormone production and metabolism.
Selenium is an essential mineral that helps the body to recycle iodine. That’s the reason the thyroid has the highest selenium content (per gram of tissue) of all our organs.
Therefore, it’s thought that low selenium levels contribute to hypothyroidism through alternate mechanisms related to iodine. For this reason it’s fundamental to eat a diet that contains many selenium-rich foods, such as:
Zinc is an essential mineral required to regulate Thyroid Stimulating Hormone (TSH).
In fact, the metabolism of zinc and thyroid hormones are closely interlinked, which is why a deficiency can lead to alopecia (hair loss).
While zinc deficiency is very uncommon in the developed world, it’s still recommended to eat a variety of zinc-rich foods. This includes:
Iodine is also important for thyroid health, but in reality insufficient iodine levels that can harm the thyroid is extremely rare in developed countries.
You’re much better off focusing on selenium and zinc-rich foods, many of which contain iodine anyways.
“You can’t out-exercise a bad diet.” This is true, especially when your metabolism is slower than normal. That’s why this article places so much emphasis on dietary changes.
However, if you want to kick-start your weight loss then regular exercise is the best way to do it.
Weight loss ultimately comes down to expending more energy (calories) than you consume. Although it’s much more complex than “eat less, move more” (there are many biological factors to consider), being active helps to burn additional calories. It also improves aspects of health that even perfect nutrition can’t provide, such as strength and mobility.
You don’t have to put yourself through miserable high-intensity workouts either. Research shows that low-intensity exercise that lasts longer – such as regular long walks – are just as effective for weight loss, especially if you are just starting out.
A general guideline is to walk for at least 60 minutes or 10,000 steps on most days.
Unable to do cardio exercise
Regularly lifting weights (or bodyweight exercises) is also highly beneficial, especially if mobility is an issue for you. In fact, it’s equally as important as cardio and we should be doing both where possible.
Known as resistance exercise, it still helps burns additional calories, but with the added benefit of building lean muscle. The more muscle you have, the faster your metabolism and the less likely you are to fall ill.
There are numerous resistance exercise programs on Youtube for beginners, and you can do it all at home if you invest in a pair of dumbbells or even one kettle bell.
