Is obesity a disability under the Equality Act 2010?

Obesity can be a disability as defined by the Equality Act 2010. A disability under the Equality Act 2010 is a physical or mental impairment that affects a person's ability to carry out normal day-to-day activities. The adverse effect must also be substantial and long term. Whether or not obesity is a disability depends on the extent and effect of the obesity. Moderate obesity is unlikely to be considered a disability, but more extreme cases may be considered a disability under the Equality Act 2010.

Obesity sometimes has other medical conditions, such as diabetes, associated with it. Those medical conditions can themselves amount to disabilities, irrespective of whether or not the obesity itself is disability.
