Introducing The TerriAnn 123 Diet Plan

Get real results in just 3 STAGES: We have 3 stages for losing weight and a maintenance stage for maintaining your goal weight. 

Our Stage 1 “10 Day Boost” – fast and highly motivating weight loss

This stage is made up of proteins, vegetables, dairy, fats, sugars, cupboard essentials and limited starchy carbohydrate allowance, to kick-start your weightloss.

Stage 2: Introducing extra foods

During this stage you continue to eat the same foods as in stage 1 but you now introduce new higher allowance for starchy carbohydrates plus lots of fruit.

Stage 3: Keeping weight loss moving 

During this stage to keep your weight loss momentum we revert back to the lower starchy carbohydrate allowance but continue to enjoy fruit.

The Switch: Kick starting weight loss

On weekly basis you will SWITCH between stage 1, 2 and 3 this is our way of kick starting your weight loss each week.

  • What makes us different?

    The reason The TerriAnn 123 Diet Plan is so successful for so many people is because we understand that everybody has different goals and objectives.

    The Plan was designed by a working mother of 4 who was fed up of unrealistic expectations and expensive memberships. TerriAnn Nunns created the plan to suit people of all abilities but most importantly REAL PEOPLE.
