Why protein is important

Protein-rich food helps your body to recover and heal quickly after weight loss surgery. After surgery you should consume around 60 grams of protein each day. If you you have laparoscopic or open surgery, the body requires enough protein each day for it to heal.  

Patients over 60 are at a greater risk of complications during weight loss surgery and could require extra protein to aid the healing process, which can be longer for older people. 

Understanding the structure and function of protein  

The word 'protein' comes from the Greek word 'protos',  meaning 'first', signifying the primary role of protein in the body.

Around 40 per cent of protein in the body is in skeletal muscle. Amino acids form the basic constituents of protein, which are required for a wide-range of bodily functions. 

The different ways proteins work

  • As enzymes to create chemical reactions;
  • as hormones for sending chemical messages;
  • as buffers for the regulation of acid;
  • as antibodies for the immune system;
  • as transporters such as albumin, hemoglobin, transferrin and retinol-binding protein.
  • and acute-phase responders that guide the body’s response during acute critical illness.
