Once you’ve found a trainer you respect and trust, it can be tempting to ask for all sorts of advice from him or her. Do they like one brand of running shoes more than another? Can they recommend a reasonably priced sporting goods store? But you need to be careful before you ask for, and follow, specific nutritional advice.
Yes, many trainers have had success monitoring their own diet and nutritional needs, but this does not mean they are qualified to dispense advice to the general public. Only trainers who have spent a significant amount of time studying nutrition or have a degree or work experience in food sciences should be relied upon for such guidance. Why? Human anatomy, digestion, and metabolism are complicated chemical reactions that no two bodies handle exactly the same way. Sometimes, conventional wisdom like “fewer calories = lower weight” is challenged by a hormonal conditional like an underactive thyroid or an issue like Cushing’s disease. Those struggling with obesity may also be facing issues like Type 2 Diabetes, and so diet becomes a very crucial component of good health. For all your trainer’s expertise and knowledge, don’t assume that he or she is the best person to turn to for nutritional advice.
Instead, contact a board-certified nutritionist, speak to your physician, or enroll in a medically-supervised weight-loss program. Alternatively, if your goals are not weight-loss related (for instance, you want to build muscle mass), consider looking for sports-nutritionist who can make sound recommendations that minimize stressful side effects of a calorie-heavy diet.
