According to the graphic:

While these figures illustrate the incredible size of modern megacities, recent population data shows that the actual numbers are often even larger..

The global significance of megacities

Megacities are more than just population centres. They are hubs of economic power, cultural exchange, and innovation. Yet, their rapid expansion also creates pressing challenges:

His allegations, focused on Karnataka’s Mahadevapura constituency, point to alleged irregularities such as duplicate voter entries, fake addresses, mass registrations, and mismatched photographs.

Gandhi said his team spent six months gathering evidence, demanding not only transparency but also access to digital voter rolls and CCTV footage from polling stations.

The charges have unleashed a political firestorm. Gandhi carried his protest to the streets of New Delhi, where he and several opposition leaders were detained during a march to the ECI headquarters.

The ruling BJP and its allies swiftly countered, accusing Gandhi of trying to discredit India’s democratic institutions for political mileage. Some leaders even demanded that he embark on an “apology yatra” across the country.

During a discussion with Abigail Johnson Boakye on Qonversations, Indian Journalist Sumit Singh added his voice to call for transparency and a background to the political uproar.

The commission’s ultimatum

The Election Commission of India (ECI) has responded in unusually strong terms, branding Gandhi’s claims “baseless, absurd, and without merit.” Citing Rule 20(3)(b) of electoral law, the Commission has issued an ultimatum : Gandhi has seven days to either submit an affidavit with evidence or issue a public apology. Should he fail to comply, the Commission warned, his charges would be treated as null and void.

This sets up a critical standoff. With state elections, including Bihar’s, just months away, the dispute has elevated the issue of electoral credibility into the national spotlight.

For Gandhi, the choice ahead is fraught with risks:

In general, the recommended daily intake can range from 2,100 to 4,800 calories for adult men and from 1,750 to 3,400 calories for women. In food terms, that ranges from the equivalent of 35 McDonald's chicken nuggets per day at the low end to 96 at the top end. 

In 2022, the average American consumed the calorie equivalent of 10.6 McNuggets a day. In contrast, the average person in Burundi, Somalia, Lesotho, and Yemen consumed only around five nuggets' worth of calories each day. 

Over time, the amount of food available to most people, and therefore the amount they eat, has been rising. This is a result of poverty reduction as well as improvements in the way we produce and transport food. In most cases, this is a benefit, although in some wealthy countries, a surplus of food has led to serious health problems.

The inequality across the globe is not a recent trend, but a long-term challenge. According to the FAO's 2023 State of Food Security and Nutrition report , over 3.1 billion people, which is nearly 40% of the global population, cannot afford a healthy diet. Even more concerning is that this number has risen by 134 million since 2019, driven by overlapping crises: COVID-19 pandemic fallout, climate-induced harvest failures, inflation, and economic slowdowns.

These figures expose a multi-layered nutritional inequality, where calories are not just unequally distributed, but also increasingly inaccessible for the low-income group. A 2023 World Bank analysis revealed that in some low-income countries, households allocate up to 60% of their income to food.  

However, progress in some parts of the world has been rapid. The chart comparing calorie intake in 1980 vs. 2022 shows Vietnam and Ghana making significant gains, with Ghana's per-person calorie consumption more than doubling. This success is rooted in long-term agricultural investment, better food distribution, and poverty reduction strategies. Ghana, for example, has expanded public agricultural extension services and promoted farmer cooperatives.

Kenya saw a 10.2% decrease in average calorie intake, despite GDP growth and urbanisation. This reflects deeper structural problems, including rising food import dependency, regional inequality, and stagnant rural incomes. According to the report , rural communities have seen stagnation in dietary diversity and food availability.

Meanwhile, another graph shows China's dramatic rise in calorie intake over the past four decades, which closely aligns with its GDP growth. In the 1980s, China implemented market-oriented agricultural reforms, lifting millions out of hunger. Today, China also strategically uses international trade agreements and grain reserves to stabilise food prices. Other countries, including Mali, which has suffered from widespread violent conflict, and Indonesia, have seen less dramatic progress. Today, Indonesia is rolling out the world’s most ambitious free meals programme to close its nutritional gap. More than 80 million people are expected to benefit by 2029.

While undernutrition remains a critical issue in parts of the Global South, a different concern arises in high-income countries: overnutrition and obesity. The WHO warns that the worldwide prevalence of obesity more than doubled between 1990 and 2022. In the UK, for example, over one-third of adults are obese, driven in part by ultra-processed diets.

However, despite the concerns of unhealthy overeating, the biggest problem currently facing the world remains undernourishment. The success stories of the past thirty years demonstrate that it is a problem that can be conquered, but the failures indicate that its demise is far from guaranteed.

*Obviously consuming all your calories in the form of chicken nuggets does not represent a healthy diet. McDonald’s nuggets are used only as an example, other brands have similar nutritional profiles.
