Leptin is a hormone that helps manage appetite levels. If you are feeling lethargic or if you want to lose a little bit of weight, you may require more leptin in your system. Leptin works by informing your brain about how much you have in your fat reserves.
For most cases of food poisoning, symptoms tend to come on within one to three days of eating the contaminated food. However, for some types of food poisoning, this 'incubation period' can be as long as 90 days.
The symptoms of food poisoning do not typically last more than 48 hours. If two days have passed since your symptoms first appeared, it is time to call a medical professional. Remember that severe symptoms, such as bloody stool, dizziness, muscle weakness, and severe stomach cramping should be taken seriously.
