GI Lean Products - Research has shown that following a healthy eating plan based largely on Low Glycaemic foods can help us to lose excess body fat. High G.I. foods are broken down quickly, causing a sharp rise in blood sugar levels and a ‘rush’ of energy. However, because these high G.I. foods are burnt up so rapidly, blood sugar levels and energy quickly slump leaving us feeling hungry and tired.  Low G.I. foods are digested slowly sustaining energy levels and giving a feeling of fullness. GI Lean products are designed to provide ongoing energy whilst eliminating unwanted body fat in a safe and realistic way.  GI Lean products are endorsed by Biggest Loser South Africa. Only effective as part of a kilojoule restricted diet. It is not recommended to lose more than 1.5kg per week.
