By acting to increase metabolism, thermogenic foods are contraindicated in cases of:
- Hyperthyroidism, because this disease already increases metabolism naturally and the use of thermogenics can worsen the symptoms of the disease;
- Heart disease, because it increases heart rate and stimulates the heart;
- High blood pressure by increasing blood pressure;
- Insomnia and anxiety, as they increase the alertness of the body, preventing sleep and relaxation;
- Migraines, because increased blood pressure can lead to worsening of headaches;
- Children and pregnant or lactating women.
Thermogenic foods are those that stimulate the nervous system and increase metabolism, helping in weight loss in weight loss diets. Some examples of these foods are coffee, pepper, green tea and cinnamon. See more in: Thermogenic foods.
Side effects
In addition to the contraindications, when consumed in excess thermogenic foods can cause side effects such as dizziness, insomnia, headache and gastrointestinal problems.
It is also important to remember that these side effects happen mainly when thermogenics are taken in the form of capsules or when they are not part of a healthy diet.
When to use
Thermogenic foods can be used along with healthy eating and regular physical activity, as they will help you lose weight, improve blood circulation, burn fat, stimulate bowel function and eliminate gas.
Thermogenics can also be consumed in the form of capsules, according to the doctor's or nutritionist's advice, and can be taken to increase the performance of the workout, improve concentration and burn fat. See more in: Thermogenic Supplements for Weight Loss.
