3. No Appetite.
Your body is built to move and expend energy, which means that you need to refuel your body as much as possible in order to be energized. However, when your body is infected with food poisoning, the last thing you may want to do is eat and for some people even the thought of food can really turn into a bad situation. Report any appetite changes to your doctor, especially if your appetite remains reduced for an extended period of time. While food poisoning can typically come and go when it is complete, if it lingers for a few days this could be a serious sign of something more serious going on in your body.
4. Muscle Weakness.
Your body is a well-oiled machine fine-tuned to use most of its energy for when the opportune time comes. This means that if you are feeling under the weather, your body will direct its energy to where it is most needed. In the case of food poisoning, your body will shift the majority of its energy to fighting the infection in your body, which could cause you to feel tired and weak in your muscles. This is not the same feeling as feeling tired after the gym and your body typically will direct you with this common sign when the time is right.
