Does the Ketogenic Diet Really Work?

People nowadays are obsessed with the idea of being healthy; after all, who doesn’t want to feel good and look good at the same time? Besides exercising regularly and sticking to a proper sleeping schedule, the most important way to achieve this is to eat a balanced diet. However, there is no ultimate diet that works for everyone; a diet that may keep one person energized throughout the day while allowing them to look fit and strong might make someone else overweight or sick. Many diets gain and lose popularity throughout the years, but there is one diet that stands out, especially for athletes and people looking to lose weight: the ketogenic diet.

Carbohydrates are one of the three macronutrients in the food we eat and it is broken down into glucose and used as the body’s primary source of energy. However, in the keto diet, little or no carbs are consumed in order to force the body into ketosis (a metabolic state where the body starts to burn fat instead of carbs as a primary fuel source). Since carbs hold onto water and no carbs are being consumed, a person who starts keto will lose weight, most of which comes from the loss of water. It can also promote further weight loss because of intermittent fasting (eating only during a certain number of hours each day; during the fasting period, the body has no food calories to make energy and is forced to use fat reserves instead).

Interestingly, the ketogenic diet can also help children with epilepsy. As mentioned before, due to the lack of carbohydrates, the body is in ketosis because the liver converts fat into ketone bodies. In a study, researchers found that since there are more ketone bodies in the bloodstream, as well as a reduction in blood sugar, the chances of a seizure are greatly lowered.

However, there are some side effects and risks associated with the ketogenic diet. Not eating enough carbohydrates can cause hunger, which in turn causes headaches and fatigue. There may also be vitamin and mineral deficiencies as well as dehydration and constipation. In addition, children who use the keto diet for long periods of time may experience slow or stunted growth because they are not getting proper nutrition.

Say Goodbye to Artificial Trans-Fat: The “Great Move”

Have you ever considered why a tub of margarine lasts for 4-5 months while a stick of butter only lasts for 1-2 months? In simple terms, margarine contains trans-fat while butter doesn’t.

As of September 17th, 2018, Health Canada has banned artificial trans-fat from all food supplies. A specific industry produced trans-fat called Partially Hydrogenated Oils (PHOs) is a health hazard and therefore, removed from all industry manufactured foods to imported goods to meals served in restaurants across Canada, taking a step forward in the “Great Move.”

The ban of artificial trans-fat in Canada will take 2 years to phase out all of the pre-existing foods containing PHOs. Through this movement, World Health Organization (WHO) is one step closer to globally eradicating artificial trans-fat. So why is WHO so determined to eliminate trans-fat?

Small amounts of natural trans-fat are found in meat and milk, but the most consumed trans-fat is the one manufactured by the food industry. Artificial trans-fat is produced from a process where liquid oil is solidified, referred to as Hydrogenation. It’s typically found in packaged snacks, baked goods, and fried foods. PHOs is the very reason why your margarine can last for 4-5 months. It provides stability that increases shelf life, while maintaining the spreadable texture and savoury taste that everyone enjoys. But at what cost?

According to numerous research papers, high intake of trans-fat has proven to increases “bad” cholesterol, and decreases “good” cholesterol. This accumulates bundles of fat in blood vessels that result in heart diseases. Excess trans-fat is associated with diabetes and heart risks.

Why is this move so crucial?

The image above displays the average trans-fat intake (g/day) of Canadians in the years 1995, 2004, and 2008 vs. WHOs recommended limit. As the graph indicates, the consumption of trans-fat in Canada has exceeded the recommended amount. Though the intake of trans-fat has reduced over time, it is still a major health issue in Canada. The image below shows that 25% of deaths in 2016 were due to cardiovascular diseases (28% if you include diabetes). By banning PHOs in the food industry, Heath Canada is eliminating a main cause of cardiovascular diseases, along with other health concerns.

Until artificial trans-fat is completely phased out of our diet, here are some helpful tips on avoiding artificial trans-fat.

  1. Read the nutrition labels carefully – Health Canada has enforced labelling on all packaged foods. Watch out for PHOs in the ingredient section!

  2. Opt-out for healthier alternatives – Natural vegetable oils such as olive or avocado oils have more benefits than harm to your body. Or you could always switch back to butter!

The Ketogenic Diet: The Key to Superior Athletic Performance?

Athletes are constantly looking for any kind of edge over their opponents. Could switching to the “keto diet” be the key to superior athletic performance?

The ketogenic diet or “keto” for short, is a diet that consists of low amounts of carbs and high amounts of fats. This drastic reduction in carbohydrates is meant to put your body into a metabolic state called “ketosis”. Ketosis sets in when your body does not have enough carbs to burn for energy, so it switches to burning fat instead.

Celebrities and professional athletes alike have turned to the keto diet in the hopes of losing fat while maintaining muscle mass. LeBron James, Kobe Bryant and Kim Kardashian are just a few of the names that have turned to the new diet.

The keto diet is also becoming more popular for the “everyday man” and not just professional athletes.  This is due to the fact that ketosis is a popular weight loss strategy. In addition to the fat burning benefits of the diet, it also makes you feel less hungry and helps you maintain muscle.

Researchers from the University of Saint Louis conducted a study on the anaerobic performance of 16 subjects that followed either a low-carb ketogenic diet or a high carb diet for 4 days. The study found that: “subjects following the low carb “keto” diet performed 4-15% worse than those adopting the high carb diet, depending on the task.”

The study author Edward Weiss, PhD, says that the keto diet could have a negative effect athletes involved in sports that require short burst anaerobic activities such as basketball and soccer.

However, the opposite may be true for endurance athletes who rely more heavily on aerobic fitness. Jeff Volek, PhD, found that long-term use of the keto diet may not only lead to a boost in performance for endurance athletes but it can also help with overall health. This is only true however, if there has been a “long-term adaption period to the ketogenic diet.”

As it turns out, “recreational athletes tend to see more consistent benefits from adopting a ketogenic diet,” says Volek. “In part because, on average, they have a greater emphasis on weight loss, metabolic and health benefits.”
