Weight loss is a complicated subject with many new theories and techniques arising every day. Scientists have researched extensively on this topic and the complex medical jargon can get overwhelming for a layman reader.
The ketogenic diet has been gaining popularity in recent years as a weight loss method. It involves consuming high amounts of fat, moderate amounts of protein, and very low amounts of carbohydrates. The idea behind this diet is to induce a metabolic state called ketosis, in which the body burns fat for fuel instead of carbohydrates. The ketogenic diet (KD) has been shown to result in body mass loss in people with disease as well as healthy people, yet the effect of the KD on thyroid function is unknown.
Clinical TrialA clinical trial, published in the journal PLoS One, sought to investigate whether the ketogenic diet could induce a shift in thyroid function and provide a metabolic advantage for healthy participants.
The researchers aimed to determine the effects of a KD, compared with an isocaloric high-carbohydrate low-fat (HCLF) diet, on resting metabolic rate and thyroid function in healthy individuals.
For a minimum of three weeks on each, participants followed two isocaloric diets: an HCLF diet (55% carbohydrate, 20% fat, 25% protein) and a KD (15% carbohydrate, 60% fat, 25% protein), with a one-week washout period in-between. So all participants had followed both dietary plans one after the other by the end of the study.
