Do you lose weight with hyperthyroidism?

Hyperthyroidism is a condition in which the thyroid gland produces too much thyroid hormone, leading to an overactive metabolism. While this may seem like a dream come true for those looking to lose weight, the truth is that hyperthyroidism can actually lead to a number of unintended consequences.

So, let’s dive deeper into whether you truly lose weight with hyperthyroidism (Spoiler alert: it’s not all sunshine and rainbows).

What Is Hyperthyroidism?

Before we get started on how hyperthyroidism affects your weight loss journey, it’s important to understand what exactly this condition entails.

The thyroid gland sits at the base of your neck and produces hormones that regulate your body’s energy use. When there are too many hormones being produced (aka an overactive thyroid), this leads to hyperthyroidism.

Some common symptoms of hyperthyroidism include:

  • Weight loss
  • Increased appetite
  • Rapid heartbeat
  • Anxiety or restlessness
  • Tremors

If any of these sound familiar — particularly that first one — keep reading!

How Does Hyperthyroidism Affect Your Metabolism?

One of the main reasons people believe they will easily shed pounds with hyperthyroidism is because their metabolism speeds up dramatically. Essentially, everything in their body happens at lightning speed due to excessive amounts of thyroxine (T4) and triiodothyronine (T3) hormones circulating through their bloodstream.

In fact, studies have shown that individuals with hyperthyroidism burn approximately 1.5 times more calories than someone without the condition! This means even if they maintain healthy eating habits, exercise frequently and don’t change anything about their lifestyle whatsoever…they could still be shedding unwanted pounds while taking bets from all sides!


While initial rapid weight loss may sound exciting – especially if you’ve been working hard to achieve your weight loss goals – this effect unfortunately doesn’t last forever. Eventually, as the body adjusts to its new hormonal status quo, that initial weight loss fizzles out like a soda can left too long in an open fridge.

Hyperthyroidism And Muscle Breakdown

Here’s another kicker: hyperthyroidism not only impacts your ability to lose fat but also muscle mass! As mentioned previously, individuals experience rapid calorie burns with higher concentrations of T4 and T3 hormones… BUT (yes it gets worse!) their metabolism may actually start breaking down more than just fat cells — especially if they’re not taking good care of themselves by nourishing properly or maintaining productive exercise routines (we’re looking at you couch potatoes!).

Excessive triiodothyronine levels have been known to lead directly to lower protein synthesis[1] which consequently leads directly towards muscle breakdown (hence why many who suffer from hyperthyroidism feel so weak and shaky).

So while there is undoubtedly some degree of quick-fire ‘fat burning’ going on for those fortunate enough (yes i’m being sarcastic)to be diagnosed with this condition – it’s important not to forget how such extreme effects will eventually impact upon both muscles AND overall health! It makes us wonder: are these insta-worthy body transformations really worth the cost?

Medications For Hyperthyroidism Can Affect Your Weight Loss Goals Too!

For individuals seeking medical treatment for hypothyroidism like anti-thyroids or thyroid replacements (which slows down hormone production), regulating one’s weight can become trickier than playing Jumanji! Sometimes medication treatments affect appetite where food choices are altered due feeling hungry all the time. Other times people who take anti-thyroids feel sluggish with decreased regular activities since they don’t have nearly same energy levels induced via over-producing thyroxine – either way plans towards successful healthy lifestyle will be complicated if not careful.

Consider this a heads up to those of us caught between two worlds…

The Role Of Diet In Hyperthyroidism

When it comes to keeping your metabolism running like clockwork, food plays an important role. With hyperthyroidism, our body is already burning more calories than usual – so we must maintain foundational nutritious meals towards maintaining balance and endurance.

This doesn’t mean embracing the latest superfood craze or fad diet, but instead looking at ways in which a sustained healthy lifestyle through balanced diets can help reduce effects borne from hormonal changes [2].

Essential foods that will aid persons with hyperthyroidism include:

  1. Lean proteins: These work well in rebuilding any muscle breakdown caused by hormone disruption.
  2. Fiber-rich foods: Fiber improves digestive functions while decreasing unhealthy inflammation throughout entire system.
  3. Gut-friendly Probiotics: Yogurt or kefir for example have active cultures capable healing and soothing irritated stomachs – which can be common with some autoimmune conditions (we’re teaming nature against itself here!)
  4. Selenium-Rich Foods: Tuna fish & Brazil nuts are fantastic sources this mineral because they helps with hormone production as well making red blood cells healthier!

You see? A meal plan that contains multi-nutrient rich ingredients may just what’s needed—whether experiencing an overactive thyroid gland OR under performing one too! All whilst still satisfying each palette unique munchie desires!
