The Claim

Heavy carbohydrate intake, such as cola consumption, induces hyperinsulinemia, which activates Na+/K+-ATPase and amplifies intracellular potassium shifts, triggering episodes of thyrotoxic periodic paralysis in individuals with hyperthyroidism.

How it works
1 study reviewed
In plain English

High carbohydrate intake, like drinking cola, causes a surge in insulin that drives potassium into cells, leading to muscle weakness in people with an overactive thyroid.

See the scientific wording

Heavy carbohydrate intake, such as cola consumption, can trigger episodes of thyrotoxic periodic paralysis in susceptible individuals by inducing hyperinsulinemia, which amplifies intracellular potassium shifts via Na+/K+-ATPase activation in the setting of hyperthyroidism.

Why this might work

When someone with an overactive thyroid eats a lot of sugar, their body releases a lot of insulin. This insulin, combined with high thyroid hormone levels, forces too many potassium ions into muscle cells. As potassium leaves the blood, the electrical signal needed for muscles to contract fails, causing sudden weakness or paralysis.

  1. Study: Pop-provoked paralysis: silent Graves’ disease presenting as thyrotoxic periodic paralysis

    In someone with an overactive thyroid, drinking a sugary soda like cola can cause muscles to become weak because the sugar makes the body release insulin, which pulls potassium into muscle cells — leaving too little in the blood. When the thyroid problem is fixed, this doesn't happen anymore.
