Less hungry when it’s hot?
In winter, you’d rather eat plates full of spaghetti. As soon as it gets warm, you feel more like eating lighter meals and smaller portions. How does that happen?
It’s down to two reasons that, once you know them, are as clear as an ice cube:
Body temperature
Your body needs energy to maintain a stable, healthy temperature of 37 degrees. When it’s cold outside, your body needs plenty of energy (food) to stay warm. When the sun is shining, your body naturally gets warm enough and you need less food. Your feeling of hunger then decreases because your body simply needs less energy. Sounds simple—and it is.
Thirst
When it’s warm, you sweat more. Your body needs more fluids, so you get thirsty more quickly. Drinking plenty then gives you a full feeling. And therefore less appetite.
