Can A Depleted-Glycogen “Sleep Low” Strategy Improve Your Performance?

For athletes, especially endurance athletes, the nutrition dogma has always been to consume significant amounts of carbohydrates post-exercise in order to maximize recovery and promote the best training adaptations. It’s well accepted in the research that muscle glycogen – the carbohydrate stores on your muscles – is replenished much more readily in the first few hours after training. Higher carbohydrate (and protein) meals help to rebuild glycogen and to offset the training-induced increase in cortisol stress hormones.1,2 But what would happen if you didn’t eat after exercise? Would it completely derail your recovery and future performance? Many believe so. But

Ancestral Solutions for A Sluggish Thyroid

Do you feel tired? Is your mood unusually low? Do you have steady weight gain despite eating well and exercising? If you answered “yes,” your thyroid may be struggling to keep up with the demands of daily life. Your thyroid gland effectively sets your body’s thermostat and metabolism. It can be sluggish when the conversion from your body’s primary thyroid hormone – thyroxine (T4) – to the “active” or useable form – triiodothyronine (T3) – is impaired. This condition is often termed subclinical hypothyroidism because patients can exhibit some of the classic symptoms of hypothyroidism – fatigue (especially in the

Vitamin D & Endurance Sport Performance

Endurance athletes are meticulous trainees, spending countless hours planning their training programs and nutrition strategies to successfully complete the “miles” required to achieve their goals. It takes focus and dedication to be a successful distance athlete, yet there is one vitamin in particular even the most studious athlete will likely not replenish adequately to meet their performance goals. Vitamin D has been gaining significant momentum recently in the research for its ability to influence over 1,000 different genes in the body and subsequently some important performance parameters. Failing to get sufficient vitamin D regularly can negatively impact many endurance parameters,

Creatine for Athletic Performance and Health

When you hear the term creatine, you likely think of the tubs of muscle-building supplement typically used by younger men to increase lean muscle and improve their physique. However, creatine is a naturally occurring protein in the body, and is in fact found in great abundance in animal protein. So, what exactly is Creatine? Creatine is a protein made up of 3 amino acids––arginine, methionine and glycine––that is produced naturally in the body. It’s a high energy molecule that helps to produce ATP, the energy currency of every cell in your body. Without ATP, your cells wouldn’t have the fuel

Vitamin D and Omega-3 Supplements on The Paleo Diet

Choosing a Paleo diet and eating more in tune with how we’ve evolved provides the body with a robust amount of essential protein, healthy fats, gluten-free carbohydrates and nutrient dense veggies. An ancestral approach to eating also provides your body with key nutrients, vitamins and minerals the way nature intended. Does this mean that supplementation is unnecessary if you’re following a Paleo lifestyle? It’s a complicated question. Most articles and blogs about supplements inevitably discuss the benefits or drawbacks of multi-vitamins. Research shows that if you eat a diet centered around the most nutrient dense foods – quality meats, veggies

Where Does the Vaccination Debate Leave Paleo Followers?

If you thought religion and politics were the most taboo topics at the dinner table, there is now definitely a third hot button topic to add to the list. The vaccine debate has become such a contentious issue that even many leading functional doctors and researchers with expertise on the subject prefer not to speak out. Regardless of what they may say, someone will likely be offended. And, knowing the answers are not black and white, there doesn’t seem to be enough room in print to truly delve deep into the topic. Recently, pro-vaccination groups have become so frustrated with

Is Distracted Eating Sabotaging Your Health?

How often do you sit down at a table with no distractions and chew your food thoroughly? Or take a proper lunch break at work? In today’s hyper-connected world it’s important to get back to basics not only with your food choices, but also in how you consume your meals. You might thoughtfully prepare your own lunch and pack healthy snack foods, but do you end up snacking throughout the day at your desk – mindlessly eating nuts, energy bars or fruit despite not actually being hungry? Or perhaps at the end of a long day you relax on the

The Hydration Debate Gets Heated

As we move into the summer, the competitive season for endurance sports hits full swing. Regardless if you’re an experienced runner or novice, you’ve likely been reminded by your run coach or peers “make sure you drink enough water during your run!” For years the recommendation from run coaches has been to drink before you are thirsty, to prevent dehydration and subsequent decrements in performance. But if you aren’t racing at the front of the pack, do you need this much water? Hydration is currently a hot topic and it’s divided into two main camps: the traditional camp who believes

The marathon and triathlon seasons are fully underway and this year over half a million people will complete the marathon and thousands more participate in triathlons and other endurance events.
