What to eat after food poisoning keto?

In this article, we are going to answer what you can eat after food poisoning on keto, what is keto, what is food poisoning, and what diet is recommended when you have food poisoning. 

What can you eat after food poisoning on the keto? 

After food poisoning, a bland diet is usually the perfect diet to decrease symptoms and make you feel better. Some food you can add after food poisoning to keep you in ketosis is

  • Eggs and scrambled eggs are a good idea but don’t add dairy or vegetables. You can only add ham or turkey breast
  • Chicken broth
  • Plain chicken breast
  • Turkey breast
  • Butter 
  • Plain low-carb cracker
  • Look for keto bread and eat it with some butter
  • Drink plenty of water and try some sugar-free electrolytes. 

Below, you will find the proper diet to treat food poisoning and you should continue with a bland or brat diet for a few days until you recover completely. My advice, try to rest your body from ketosis so it can fully recover and eat what your body needs. 

Try not to add too much fat until diarrhea and stomach pains have completely gone. 

What is keto? 

Keto or ketogenic diet is a term to refer to very low carbohydrate diets, such as the Atkins diet. The main idea of the keto diet is that you eat your whole calories from fat and protein. Fat is the main source of energy for your body in this diet. 

When on keto, you have to cut all carbohydrates like sugar, soda, pastries, white bread, rice, and high carbohydrates fruits and vegetables.

Keto works when you eat less than 50 grams of carbohydrates per day, your body starts running out of its main source of energy, carbohydrates, so it starts using fat as the main source of energy. It takes about 4 to 7 days to achieve this process known as ketosis. 

You need to eat enough fat so you can ensure that your body dont use proteins from your muscles as energy or you will lose muscle mass. This whole process has one objective and it is to lose weight. 

Keto diets are also used with patients that have epilepsy. When you are on keto, your brain activity decreases because you are not using carbohydrates as the main source. This process helps epilepsy or the brain activity that causes convulsion to decrease. 

The ketogenic diet is also used to prevent heart disease, brain disease, acne, and other medical conditions. If you are trying to lose weight, you need to do the keto diet always with a doctor or nutritionist’s supervision because it can lead to other health problems. 

When you achieve a metabolic state of using fat as the main source you can use blood, urine, or breath tests to confirm you have entered ketosis. 

What is food poisoning? 

Food poisoning or also called foodborne illness is caused when you eat something that is contaminated with bacteria, viruses, or parasites. Sometimes you don’t have to ingest the virus or bacteria, it is enough by eating their toxins to have symptoms of food poisoning. 

There is no known exact point when food gets contaminated. It can happen at any point in the process of production and the only way to ensure that there are no viruses, bacteria or parasites is by heating it to a safe temperature to kill all of them. 

Apart from the process and production of a product, contamination can also occur if food is not handled or cooked correctly. Symptoms might start within an hour of eating contaminated food. Symptoms include

  • Vomiting
  • Nausea
  • Stomach pain
  • Diarrhea
  • Fever

The whole sickness caused by food poisoning can last one day to several days. Food poisoning is life-threatening to immune-suppressed patients, the elderly, pregnant women, and young children. 

The most common contaminants that can cause food poisoning are

  • Campylobacter: symptoms start from 2 to 5 days
  • Clostridium botulinum: symptoms start from 12 to 72  hours
  • Clostridium perfringens: symptoms start from 8 to 16 hours
  • E.coli: symptoms start from 1 to 8 days
  • Giardia lamblia: symptoms start from 1 to 2 weeks
  • Hepatitis A: symptoms start from 28 days
  • Listeria: symptoms start from 9 to 48 hours 
  • Noroviruses (there are very common in the summer): symptoms start from 12 to 48 hours
  • Rotavirus: symptoms start from 1 to 3 days
  • Salmonella: symptoms start from 1 to 3 days
  • Shigella: symptoms start from 24 to 48 hours
  • Staphylococcus aureus: symptoms start from 1 to 6 hours

What is the diet recommended when you have food poisoning?

When you have food poisoning, even if you are on keto, you should eat bland food that does not irritate the stomach, large intestine, or colon. Diet is part of the treatment to recover from food poisoning. It is very important to not add fiber or food that can irritate your intestine. Too much fat can worsen diarrhea. 

You can follow the BRAT diet

  • B for Bananas
  • R for rice, plain white rice
  • A for applesauce
  • T for toast or bread

The Brat diet has nothing to do with the keto diet but it will be a good idea to rest from ketosis for a few days so your body can recover completely. 

Other foods you can include in your bland diet are boiled potatoes, turkey ham or turkey breast, chicken breast,  unseasoned crackers, and apple juice.

You must add liquids so you don’t dehydrate.

  • Clear broth like chicken or beef broth without fat
  • Electrolyte-enhanced water
  • Decaffeinated tea like chamomile tea
