The liver is the largest internal organ in your body and one of the busiest. It's involved in more than 500 functions, from digesting fat to storing vitamins, and it plays a big part in how you use energy and store fat. Here's a simple introduction.
What does the liver do?
Processes nutrients
Nutrients from your meals travel first to the liver, which stores glucose, regulates blood sugar and releases energy between meals.
Manages fat
The liver makes, breaks down and packages fats for the rest of the body and produces bile to digest dietary fats.
Neutralises toxins
The liver transforms alcohol, medications and environmental chemicals into forms the body can safely eliminate.
When the liver gets overloaded
When sugar, calories and alcohol regularly exceed what your body needs, and you're not very active, fat can build up in the liver. This is linked with weight gain around the middle, blood sugar ups and downs and feeling tired. Thankfully, the liver can recover remarkably well with healthier habits.
| Factor | Effect on the liver |
|---|---|
| Sugary foods & drinks | Fructose converts to liver fat |
| Alcohol | Adds to the liver's workload |
| Inactivity | Less fat is burned for energy |
| Poor sleep & stress | Unsettle metabolic hormones |
How to support your liver and metabolism
Eat plenty of vegetables, lean protein, beans, whole grains and healthy fats. Choose water, tea or black coffee over sugary drinks. Stay active every day and include strength exercises. Keep alcohol low and sleep 7 to 9 hours. Natural nutrients such as choline, betaine, milk thistle and green tea compounds support liver health and fat metabolism.
