The low-carbohydrate ketogenic diet has become quite popular due to its potential advantages for improving metabolic health, weight loss, and cognitive function. However, concerns have been expressed about how it may affect the thyroid and adrenal glands in particular, as well as the balance of hormones. We spoke to Rahul Kamra Founder, Ketorets Nutrition Pvt Ltd, who listed the possible impacts of the ketogenic diet regarding thyroid and adrenal function.
According to StatPearls, the ketogenic diet, often known as the high-fat, low-carb diet, is a nutritional strategy designed to promote energy, improve mental clarity, and aid in weight loss. This diet creates a metabolic condition known as ketosis, in which the body uses fat as its main fuel source rather than carbohydrates, by drastically cutting back on carbs and boosting intake of fat and protein.
Ketogenic Diet’s Effect On Thyroid Function
Weight Loss and Metabolic Effects
“Improvements in metabolic markers including insulin sensitivity and lipid profiles, as well as weight loss, are frequently linked to the ketogenic diet. Given that insulin resistance and obesity are known to affect thyroid hormone levels, these modifications may have an indirect impact on thyroid function”, said Kamra.
According to an 8-week trial on 39 obese adults published in the Harvard Th Chan School Of Public Health, participants lost a mean of 13% of their initial body weight when put on a very low-calorie ketogenic diet. They also saw significant decreases in blood pressure, insulin levels, fat mass, and waist and hip circumferences.

Effect on TSH
The ketogenic diet’s potential impact on Thyroid-Stimulating Hormone (TSH) levels is a further cause for concern. The pituitary gland secretes TSH, which activates the thyroid gland to create thyroid hormones.
Macronutrient Composition
“Thyroid hormone synthesis and conversion may be impacted by the high-fat, low-carb characteristics of the ketogenic diet. Low-carb diets may lower T3 levels, as a result of decreased insulin production”, added Kamra. …
