THE SCIENCE OF SATISFACTION

The science behind why you feel fuller for longer.

Each cookie contains special proteins that respond to the stomach’s naturally acidic environment, forming a soft, gel-like structure. This structure is digested gradually, helping support longer-lasting satisfaction between meals.

A ROUTINE DESIGNED FOR REAL LIFE

Why Cookie Diet fits real life

A practical structure designed to make an energy-reduced routine simpler to follow.

01

Convenient by design

Take one daily bag with you and enjoy the cookies at the recommended intervals—without preparing daytime meals. Finish the day with a balanced evening meal.

02

Designed to support fullness

The cookies contain a specially developed protein blend designed to support satisfaction between planned eating times, making an energy-reduced routine easier to follow.

03

A simple daily structure

A clear daytime routine removes much of the planning and portion guesswork that makes many eating programs difficult to maintain.

04

Support beyond weight loss

After reaching your goal, transition to balanced everyday meals and use the cookies as a convenient, portion-controlled snack between meals.

05

Developed in 1975

Dr. Siegal’s Cookie Diet has been used internationally for over 50 years.

Talk to your GP before beginning any major weight-loss program. Use the product as directed as part of a balanced approach.
