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.
How long food poisoning takes to set in depends on the type of food poisoning. Generally, symptoms can set in within two to six hours after food has been consumed. But sometimes symptoms can appear within a few days or a few minutes. Illnesses caused by food poisoning can last up to 10 days. Some food poisonings can be fatal.
