Introduction
For individuals who are not accustomed to exercising on an empty stomach, it is not recommended to perform strength training in a fasted state. This is especially true for those prone to hypoglycemia or individuals with diabetes, as fasting during strength training may increase the risk of low blood sugar, potentially leading to dizziness, weakness, or even fainting. It is advisable to consume a moderate amount of food before training to provide sufficient energy to support the exercise session.
Generally, whether it is appropriate to perform strength training on an empty stomach depends on individual circumstances. If a person is in good health, they can usually do strength training while fasting; however, if someone is physically weak, fasting strength training is generally not recommended. Seek medical advice promptly if any discomfort occurs. Detailed explanations are as follows:
For healthy adults, performing moderate- to low-intensity strength training—such as bodyweight exercises or light-resistance machine workouts—while fasting is relatively safe. This approach may help enhance fat burning efficiency and improve muscular endurance.
Individuals who are not accustomed to exercising on an empty stomach should avoid fasting before strength training. In particular, those prone to hypoglycemia or individuals with diabetes may face an increased risk of low blood sugar when training fasted, potentially leading to dizziness, fatigue, or even fainting.
It is advisable to consume a moderate amount of food before training to provide sufficient energy for the workout. Additionally, pay close attention to your physical condition during exercise and discontinue training immediately if you experience any adverse symptoms, seeking medical assistance as needed.
