In many Western countries, drinking alcohol is often a leisurely social activity. People typically visit bars or pubs in the evening to enjoy drinks with friends, focusing more on conversation than on food.

Common beverages include wine, beer, or light cocktails, which generally have a lower alcohol content compared to Indian spirits. These drinks are frequently consumed without substantial food, with bars offering light snacks such as peanuts or crisps that are easy to nibble on.

Additionally, many Westerners are health-conscious, preferring to avoid heavy eating alongside alcohol to limit calorie intake and prevent weight gain.

Food And Alcohol In Indian Culture

In contrast, in India, alcohol consumption is typically part of social gatherings known as ‘parties’ or daawats, where food plays a central role. Drinking is often accompanied by eating, a practice called chakhna or snacking. The alcohol consumed, often whiskey, rum, or beer, tends to have a higher alcohol by volume (ABV).

Indian culture places great importance on food, and it is widely believed that drinking on an empty stomach is harmful. Hence, large meals are consumed both before and during drinking. Furthermore, alcohol can increase hunger, as it lowers blood sugar levels, prompting cravings for energy-rich foods.

Numerous scientific studies have explored why alcohol triggers an increased appetite and cravings. If you’ve ever noticed feeling hungrier after drinking, you’re not alone.

How Alcohol Tricks Your Brain Into Feeling Hungry?

• Impact on the Brain: Alcohol affects the hypothalamus, the part of the brain that regulates hunger, temperature, and other vital functions. Research from 2017 showed that alcohol activates certain neurons (AgRP neurons) that signal hunger, prompting us to eat.
• Heightened Taste and Smell Sensitivity: Alcohol increases sensitivity to taste and smell, making food seem more appealing and delicious. This enhanced sensory perception also involves the hypothalamus.
• Drop in Blood Sugar: Alcohol can cause blood sugar levels to fall, leading to low energy. The brain compensates by signalling hunger, which often results in cravings for sweet or salty foods.
• Reduced Self-Control: Drinking impairs decision-making and self-control, making it harder to resist high-calorie fried or junk foods rather than healthier options.

Scientific Evidence

A 2017 study published in Nature Communications demonstrated, through experiments on rats, that alcohol directly activates hunger-related neurons in the brain.

Another 2015 study found that people tend to consume more calorie-dense, salty, and fatty foods after drinking, indicating that alcohol not only increases appetite but also changes food preferences.

So, next time you find it difficult to resist overeating after a few drinks, remember this is a natural response of your body.
