A slimming diet can be assisted by dietary supplementation at various levels. In more detail:

• stimulation of preferential fat consumption: supplements that influence the body’s preference for the main energy source are yerba mate, essential and semi-essential fatty acids, carnitine, pyruvate, conjugated linoleic acid and garcinia cambogia.
• Anorectic function: supplements that hinder the onset of appetite are citrus aurantium, 5-HTP, garcinia cambogia, Hoodia gordonii and dietary fibres.
• Adipocyte emptying: supplements that promote the emptying of adipocytes from the fat contained therein are green tea, citrus aurantium, yohimbine, guarana, coleus forskohlii and conjugated linoleic acid.
• Obstructing fat absorption: dietary fibre, green tea, calcium and chitosan belong to this category.
• Hindering carbohydrate absorption (for strongly low-carb diets): products that may hinder carbohydrate absorption are dietary fibres, guarana, Phaseolus vulgaris L. and Gymnema sylvestris.
