Can You Gain Muscle Mass with Hyperthyroidism? Experts Recommend This
Hyperthyroidism and muscle mass is a combination that poses significant challenges for those looking to gain weight and build strength.

TL;DR
- Hyperthyroidism accelerates metabolism, causing involuntary weight loss and muscle degradation.
- It is possible to gain muscle mass and strength under medical supervision.
- Key pillars for improvement include nutrition, training, and clinical follow-up.
- A progressive increase in caloric intake, prioritizing quality proteins, complex carbohydrates, and healthy fats is recommended.
- Strength or resistance training stimulates muscle hypertrophy, but overtraining must be avoided.
- Adequate rest (7-9 hours) aids muscle recovery and hormonal regulation.
- Using thyroid hormones or supplements without medical supervision can be counterproductive.
