Experts explain why people gain weight in summer despite eating less

Many people find themselves gaining weight during the summer, even when they feel they are eating less. A primary culprit is often overlooked: liquid calories. Sugary drinks like lemonades, iced teas with syrups, fruit smoothies, and alcoholic beverages can pack hundreds of calories without providing the same sense of fullness as solid food. This can lead to consuming more calories overall without realizing it.

Another common reason for summer weight gain is mistaking thirst for hunger. Increased sweating in hot weather leads to dehydration, which can manifest as fatigue or low energy. Instead of reaching for a glass of water, people often grab a snack, further increasing their calorie intake. Adequate hydration is also crucial for maintaining a healthy metabolism, and dehydration can intensify cravings for sweet or high-calorie foods.

Summer also brings a shift towards eating outside the home, with frequent outings, barbecues, and dining on restaurant patios. While these social occasions are enjoyable, they often involve meals prepared with more fats, sugars, and sauces than home-cooked food. Additionally, social eating can distract from hunger and satiety cues, leading to overconsumption.

Finally, the disruption of regular meal schedules contributes to weight gain. Longer evenings and more frequent excursions can lead to irregular eating times. Some people skip breakfast or have late lunches due to the heat, while others snack throughout the day and consume the largest meal in the evening. This inconsistency makes natural appetite control more difficult, often resulting in spontaneous snacking or overeating.
