This is a good question and although many nutritional claims are available, there’s really no such thing as a scientifically-based hypothyroidism diet. However, it’s very important that you continue working closely with your doctor, get regular check-ups, and take your medication as prescribed to ensure optimal thyroid function.
When it comes to pre-workout nutrition, your goals would follow the standard protocol which includes carbohydrates for energy and small amounts of protein to help rebuild muscle (SCAN, 2009). And although individual tolerance differs, pre-exercise meals should be lower in fat and fiber to help avoid cramping.
Examples of pre-workout foods may include:
Low-fat cheese stick with crackers
Banana with peanut butter
Small non-fat smoothie
½ tuna salad sandwich with light mayo and fat-free yogurt
Hydration is another important consideration when it comes to sports nutrition. Dehydration not only contributes to early fatigue, but it can also be a risk factor for heat exhaustion and heat stroke. Therefore water should be included before, during and after a workout. Individual fluid requirements vary person to person but in general it’s best to begin your exercise well hydrated and minimize fluid loss by following the general guidelines:
17 -20 ounces of water two hours prior to exercise
7-10 ounces of fluid every 10 -20 minutes during exercise
16 -24 ounces of fluid for every pound of body weight lost after exercise
Higher intensity workouts or those lasting more than 60 minutes may require the need to replenish electrolytes lost in sweat. You can do this by incorporating a thirst quenching sports drink for a portion of your fluid replenishment to maintain that important electrolyte balance.
Although there’s not a specific hypothyroidism diet, refueling with the right nutrients at the optimal time may enhance your performance, help minimize abdominal discomfort and fatigue, and keep you going strong.
