Weight Loss

Obesity And Weight Loss White Paper September 2017

There are countless dietary programmes on the market, but none of them recognises the possibility that certain foods, even healthy ones like tomatoes or carrots, could be problematic if they trigger an immune system response in overweight individuals. Eliminating foods that are IgG-reactive, while replacing them with similar, non-reactive foods to ensure that nutrient deficiencies do not occur, is a relatively new concept for a diet. This new published paper examines the viability of a food-specific IgG guided elimination diet as a weight loss strategy. https://www.yorktest.com/uploads/pdfs/weight-loss-whitepaper-2017.pdf
