Why do I get cold after I eat?

In this brief guide, we will answer the query, “Why do I get cold after I eat?” We will also discuss the different causes of cold sensitivity after eating and how we can stop getting cold after eating.

Why do I get cold after I eat?

There are many reasons why you feel cold after eating. It could be the result of something you ate, something you did, or a change in environmental factors. It’s very natural and normal for your body to change the temperatures depending on what you eat. Most of the time, it’s nothing serious and often goes unnoticed. 

However, sometimes these may have resulted due to some serious problems as well. So it’s absolutely necessary to know what causes the chills after eating. Some of these causes are described below:

Low-calorie diets

The number of calories you consume can greatly affect your energy production and body temperature. According to one research, long-term calorie restriction combined with adequate nutrition has been linked to lower body temperature in both lean and obese people. 

Because of the lower calorie intake, the body adapts by reducing its temperature in order to conserve energy. Furthermore, another study revealed that the more you decrease your calorie intake over time, the colder you are likely to feel. However, this drop in body temperature will make you feel cold all of the time, not just after eating.

Intermittent fasting 

Intermittent fasting is a regular eating pattern in which you alternate between fasting and eating. This can also be one of the major reasons why you feel cold after eating. If you’re intermittent fasting, then automatically your calorie intake is very low which has been shown to affect the production of energy as well as the body temperature.

Hypoglycemia, or low blood sugar, is another possible reason which can occur during fasting. Low blood sugar levels might increase your sensitivity to cold and produce cold sweats.

If you consistently feel cold while fasting, it could be a sign that you need to ingest more calories into your diet.

Some foods provide a cooling effect

Certain foods like spicy foods, cold food, and beverages can also be responsible for your lower temperature after eating. Consumption of these foods can cause a massive drop in your body temperature making you feel cold. While spicy meals may feel warm in your mouth, they may actually cause a slight drop in your body temperature by producing sweat from your body.


Feeling constantly cold after eating could also be a sign of hypothyroidism. Uncontrolled hypothyroidism causes people to feel cold after eating. Hypothyroidism happens when your thyroid gland does not produce enough hormones to boost your metabolism and keep your digestive systems operating smoothly. 

Low thyroid levels often come with high cold sensitivity. Because your body needs the energy to digest food, low thyroid levels may make you more susceptible to cold after eating.


Some people do not have as many healthy red blood cells as required by the body, resulting in anemia. Anemic persons frequently feel cold because their blood cells are unable to transport adequate oxygen throughout the body. 

Although body chills due to anemia can occur at any time of day, it is reportedly more common and frequent after eating. Feeling cold chills is one of the major symptoms seen in an anemic person. For a more detailed relation between anemia and cold sensitivity, please click the link here.

How can we stop getting cold after eating?

The best way to stop feeling cold after eating is to adjust your eating habits and lifestyle. Carbohydrate and sugar-rich foods can inflict some serious damage on your system and confuse your brain. 

It’s better to develop a habit of consuming plenty of healthy fruits, veggies, and lean protein instead of high carb and high sugar meals. Add healthy oils, proteins, and whole grains to your diet. 

Protein sources include fish, beans, and poultry, while fresh food is preferable over canned items as they may include unhealthy additives like sodium, sugar, and other chemical preservatives. It is important to get enough calories for your body’s needs to stay healthy.
