The Prophet ﷺ Predicted the Obesity Epidemic 1,400 Years Ago
Among the prophecies of the Prophet ﷺ concerning the signs of later generations is a detail so precise that modern epidemiology has only confirmed it within the last century: the appearance and spread of obesity among humanity.
The Hadith
Grade: Sahih · Bukhari
The meaning of the hadith is clear: the best of generations and centuries are those who lived with the Prophet ﷺ, then those who came after them, then those who came after them. After this, generations will appear in whose religion there is deficiency — among the manifestations of which is that they will not fulfill their vows, will betray trusts, and obesity will spread widely among them, as they eat abundantly and many of them become obese.
Obesity Was Rare for Thousands of Years
The most striking aspect of this prophecy is its precision: obesity did not appear as a widespread phenomenon until the twentieth century. This is not a Muslim claim — it is the finding of the World Health Organization and the epidemiological record.

For thousands of years, obesity was a rare sight — then in a single century it became a global epidemic. The Prophet ﷺ informed us of this more than 1,400 years ago.

Some may think the hadith speaks only about Muslims. The following data is from a study on obesity across all world regions, published by the Harvard T.H. Chan School of Public Health — the nutrition research division of Harvard University, the leading university in the United States:

Obesity and Cancer — The Lancet Study
The health consequences of obesity — which the Prophet ﷺ identified as a sign of a later generation’s moral and spiritual decline — extend far beyond weight itself. CNN Arabic reported on a major scientific study:

The Prophet ﷺ named obesity as a distinguishing feature of later generations — at a time when obesity was essentially unknown as a widespread condition. The WHO declared it a global epidemic in 1997, fourteen centuries after the prophecy. The Islamic world, particularly the Gulf states, now ranks among the highest obesity rates on earth. The question stands unanswered by any naturalistic explanation: how did the Prophet ﷺ describe the state of the world with such precision?
