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 most common symptoms are diarrhea, stomach pain, cramping, nausea, and vomiting. Because most of the symptoms of food poisoning are similar to those of other illnesses, such as a stomach virus, people aren't always sure food is the problem. If you think you've got food poisoning but aren't sure, take note: Most people get sick about 4 to 48 hours after eating the suspect food.
