Context

A low metabolic flexibility to lipid (MetF-lip) in skeletal muscle may promote ectopic lipid accumulation, thus inducing metabolic disturbances. 

What is Meta flexibility?

Metabolic flexibility is the capacity to adapt fuel oxidation to fuel availability so ATP synthesis can match its demand.

ATP synthesis is the process of creating adenosine triphosphate (ATP), the cell's energy carrier, using energy from catabolic mechanisms like cellular respiration, beta-oxidation and ketosis.

What Are Lipids?

Lipids are molecules in our body that are commonly called fats and oils, but they have many important roles beyond just storing energy. They are essential for our health and survival.

Lipids are organic molecules made mostly of carbon, hydrogen, and oxygen.

They are hydrophobic, meaning they do not dissolve in water. Lipids are a source of energy, help in building cell membranes and play a role in hormones and vitamins.

Types of Lipids

Lipids can be divided into three main types:

Functions of Lipids

Lipids are the body's long-term energy reserve. They provide 9 calories per gram which is more than carbohydrates or proteins.

Lipids are the main building blocks of cell membranes (phospholipids). They protect cells and control what goes in and out.

Lipids act like a cushion protecting internal organs like the heart and kidneys. Fat under the skin helps maintain body temperature.

Lipids help the body absorb fat-soluble vitamins (A, D, E, and K) from food.

Lipids like cholesterol are used to make hormones like testosterone and estrogen.

Whale blubber is rich in lipids and helps them survive in cold oceans.

Lipids are part of the myelin sheath which protects nerve cells and helps in transmitting signals in the body.

Good Fats vs. Bad Fats

Types of Fats in Lipids

Saturated Fats:

Found in butter, cheese, and red meat.

Solid at room temperature.

Too much can raise cholesterol levels.

Unsaturated Fats:

Found in fish, nuts, and vegetable oils.

Liquid at room temperature.

Help lower cholesterol and improve heart health.

Trans Fats:

Found in processed and fried foods.

Harmful to health as they increase bad cholesterol.
