The ‘Applied Nutrition and Supplementation’ (ANS) course written by Dr. Mendoza is designed to improve the nutritional knowledge of personal trainers and athletes. This will allow trainers to add a nutritionist role to their business. A recent case in the USA has seen a personal trainer sued for advising his client to take a supplement that ultimately led to the client’s death; how long before this happens in the UK? The ANS course is designed to meet a need in the leisure industry for better nutritional education. This education should be based on peer reviewed, scientific evidence. The course manual is comprehensive and contains over 700 peer reviewed references. The course gives trainers and athletes a sound nutritional grounding, including the basic biochemistry and physiology associated with energy metabolism. Manipulation of the macro and micro nutrients is also considered and how to optimise these to increase performance and energy levels. You will learn how to use nutritional software (provided on the course) to analyse an individual’s diet and activity levels. Based on this analyses you will then be shown how to design the ideal diet to enhance sporting performance. This section also considers making weight for sport. There has been a proliferation of supplement usage in the leisure industry, with personal trainers often being the main source of information as to their efficacy and safety. Athletes regularly use supplements in an attempt to enhance performance or perhaps avoid illness. The ANS course considers all the main supplements that are available and presents the latest research evidence, allowing trainers, athletes and nutritionists a more informed and accurate understanding of how and when to use supplementation. Also what is effective and what is just marketing hype.

A new addition to the course is access to the LEAN Man System. You will receive a complete set of lesson plans for the 12 week programme. Should you wish to you can also purchase the E-learning modules to sell to clients as part of your weight management programming. During the course you will work through these modules so as you fully understand what nutritional education your client is receiving. The LEAN Man System is an evidence based system with an 86% success rate so you can be confident when working in a nutritionist role that you are offering clients their best chance of losing weight.
