Heat and loss of appetite: how to beat it

It's hot. Very hot. You struggle to cook good meals and yet nothing helps: Mini refuses to eat. When should you be concerned and how do you prevent it from running out of energy or nutrients?


Lack of appetite in the middle of a heat wave is nothing rare or exceptional. In fact, it is a natural phenomenon. The body is an amazing, high-performance machine that self-regulates to maintain internal temperature between 36.1 and 37.8°C.

Eating makes you hot

Digestion plays a very important role in this thermal function. If in winter we are instinctively pushed to ingest more calories, it is so that we can produce more energy and warm ourselves. On the contrary, in summer, the body does not want extra heat and helps us to limit it by cutting our appetite a little. This phenomenon is called thermoregulation.

Low appetite? Nothing out of the ordinary

During a heat wave, we would lose almost 20% of our appetite. Although this is a normal and common occurrence, care must be taken not to become dehydrated and care must be taken to absorb all the nutrients necessary for theproper functioning of the metabolism. Therefore, when the mercury rises, avoid overeating or choosing foods that are difficult to digest (such as protein).

How to eat well, despite everything

So how do you avoid undernourishment during a heat wave? The first thing is to split meals. Indeed, instead of 3 hearty meals, it is better to serve much lighter ones, even if it means increasing the number of snacks between each one.


Hot, greasy or oily foods should be avoided. Instead, set your sights on fresh, raw fruits and vegetables that contain a lot of water. We think of tomato, lettuce, zucchini, melon, apple, strawberry, pear, etc.

Since chewing also contributes to the rise in body temperature, it is better to opt for liquid foods (smoothies, soups, etc.) and skip grilled meats, for example.

When to worry?

If your child is smiling, going about his business as usual, and doesn't seem to be lacking in energy, there's no reason to be alarmed. However, if he is apathetic, falls asleep all over the place, is pale and has a fever… a medical professional should be consulted.
