Is Your Thyroid Secretly Causing Weight Gain? 7 Signs & Natural Fixes You Need to Know
You may have wondered, “Is my thyroid causing me to gain weight?” if you’ve been gaining weight in spite of eating healthily and exercising. Your body weight, energy levels, and general well-being can all be greatly impacted by a malfunctioning thyroid, which is essential for controlling your metabolism. The symptoms of an underactive thyroid, the reasons behind weight gain, and natural remedies for thyroid health will all be covered in this article.
Understanding the Thyroid and Its Role in Weight Management
The thyroid is a tiny gland in the neck that resembles a butterfly. Triiodothyronine (T3) and thyroxine (T4), two hormones that control how your body uses energy, are produced by it. Your metabolism, heart rate, temperature regulation, and even calorie burning are all influenced by these hormones.
When the thyroid underperforms (a condition known as hypothyroidism), metabolism slows down, leading to symptoms such as:
- Unexplained weight gain
- Fatigue
- Cold sensitivity
- Brain fog
- Constipation
Signs Your Thyroid Might Be Behind Your Weight Gain
Let’s look at some common signs and symptoms that suggest your thyroid could be impacting your weight.
1. Unexplained Weight Gain or Difficulty Losing Weight
Sudden or persistent weight gain, particularly when it deviates from your usual eating or exercise routine, is one of the classic symptoms of hypothyroidism. Why it occurs: Even with a modest diet, it is easier to gain weight if your metabolism is slower because it burns fewer calories at rest.
2. Chronic Fatigue and Low Energy
Your thyroid may be underactive if you have good sleep but still feel exhausted during the day. Link to the thyroid: Low thyroid hormone levels can make you feel lethargic, unmotivated, and too exhausted to work out because they interfere with cells’ ability to produce energy.
3. Dry Skin and Hair Thinning
Your hair may feel brittle or begin to thin, and your skin may become dry, flaky, or itchy. What’s happening? Thyroid hormones play a role in controlling hair growth and skin cell turnover. These processes slow down when levels fall.
4. Depression or Mood Changes
Feeling down, anxious, or emotionally flat? Thyroid imbalances can affect your brain chemistry, leading to symptoms that mimic depression.
5. Irregular or Heavy Periods
Women with hypothyroidism often experience heavier, longer, or irregular menstrual cycles due to hormonal disruptions.
6. Cold Hands and Feet
Thyroid issues can affect circulation and body temperature. If you’re always cold even in mild weather it could be a red flag.
7. Constipation and Digestive Issues
A sluggish thyroid slows down your digestive tract, which can lead to bloating, constipation, and a feeling of heaviness.
How to Get Your Thyroid Checked
If any of these symptoms feel familiar, speak to your GP or healthcare provider. A thyroid function blood test can measure levels of:
- TSH (Thyroid Stimulating Hormone)
- Free T4
- Free T3
- Sometimes thyroid antibodies (to check for autoimmune thyroid conditions like Hashimoto’s)
Natural Fixes to Support Thyroid Health
There are natural ways to support thyroid function and hormonal balance, even though medication may be required for diagnosed hypothyroidism.
1. Eat a Thyroid-Supportive Diet
Certain nutrients are essential for thyroid hormone production and conversion.
Key nutrients include:
- Iodine – Found in seaweed, iodised salt, and fish
- Selenium – Found in Brazil nuts, tuna, and sunflower seeds
- Zinc – Found in pumpkin seeds, legumes, and beef
- Iron – Important for T4 to T3 conversion
- Tyrosine – An amino acid found in chicken, turkey, and dairy
Avoid over-supplementing, especially with iodine, without professional guidance.
2. Reduce Processed Foods and Inflammatory Triggers
Refined sugar, processed oils, and artificial additives can increase inflammation and disrupt hormone balance. Try focusing on:
- Whole grains (like quinoa and brown rice)
- Leafy greens and colourful vegetables
- Lean proteins and healthy fats (e.g. olive oil, avocado)
3. Limit Goitrogenic Foods if You Have a Thyroid Condition
Certain raw foods like kale, broccoli, and cauliflower can interfere with iodine uptake in large quantities.
Tip: Cooking these vegetables reduces their goitrogenic effect.
4. Manage Stress and Get Quality Sleep
Chronic stress elevates cortisol, which can suppress thyroid function. Incorporate:
- Daily movement or gentle exercise (like walking or yoga)
- Mindfulness practices, deep breathing, or journaling
- At least 7–9 hours of sleep per night
5. Exercise But Don’t Overdo It
Regular, moderate exercise raises mood and speeds up metabolism. High-intensity exercises or overtraining, however, can actually put additional strain on your thyroid.
Best choices:
- Walking
- Swimming
- Pilates
- Strength training in moderation
