After learning more about carbohydrates, do you agree with using a low carb diet as a means for weight loss? Why or why not? Include relevant research to support your answer.
After learning more about carbohydrates I still believe that using a low-carb diet as a means for weight loss can be a good idea. It can also be beneficial as a way to control early problems with diabetes type 2 that many people don’t realize can be diet controlled through proper nutrition and nutrient timing. (Volek & Westman, 2002) analyzed a collection of studies talking about some of the benefits of a low-carbohydrate data from the study collection including: body fat loss, appetite suppression,
Negatives that can result from too low of a carbohydrate diet can include: decreased metabolic rate and efficiency through diet deficient in nutrients that can lead to issues such as immunosuppression and adrenal fatigue. Therefore it is important to remember that a diet has to be sustainable to maintain performance in and out of sport.
A major aspect to consider includes the quality of foods and carbohydrates; some carbohydrates have a lower glycemic index, lower sugar content, and easier on digestion (Ormsbee, Bach, & Baur, 2014, p. 1787-1788). The quality of food also applies to fats and proteins, which we we discuss in upcoming weeks through class discussions. Finally, obesity is “Obesity is multifactorial; its causes include both excess energy intake and inadequate energy expenditure” (Volek & Westman, 2002, p. 857). Exercise can contribute to more energy expenditure and increase metabolic rate, as can proper diet. Proper nutrition, like a low-carbohydrate balanced with good fats, proteins, and nutrient dense carbohydrate sources can lead to proper weight loss. It is still important to remember that a lot more goes into a proper diet than just one aspect like low-carbohydrate intake.
As a side discussion board note I really enjoyed our (McGuire & Beerman, 2013) carbohydrate chapter and the focus on reducing added sugars and gives excellent tips at the end of the chapter in “Working Toward the Goal: Focus on Reducing Added Sugars” (p. 144). I personally try to avoid added sugars and processed grains. The only grains I have are fermented to make them easier to digest and I pay very close attention to added sugars utilizing stevia and honey in small doses as needed. I personally eat relatively low carb, but don’t scold the “traditional athlete” that fuels with carbohydrates if they understand how important carbohydrate timing is in the process.
From personal experience I think that low carbohydrate diets can and do work for weight loss. I have even experimented with a ketogenic diet for performance as an endurance athlete. In order to burn body fat it makes sense to utilize fat as an energy source. I found I can burn fat for energy on a daily basis utilizing a daily intermittent fast giving my body time to fully digest and utilize the nutrients from the previous 12 to 16 hours. I feel a sense of mental clarity during my fasts utilizing MCT oil during the fast and of course natural fat stores that everyone has. I feel this enhances my work because I don’t get the typical “rebound hypoglycemia” that some people get after breakfast and the MCT oil is easily utilized as a source of energy for the brain (Jeukendrup & Killer, 2010). However on a strict fat-burning diet, I was unable to thrive on only a fat-burning diet which resulted in muscle wasting and adrenal fatigue from what I believe was not getting enough nutrients from other sources. I have since added back in a few more good carbohydrate sources; like small doses of fermented grains, fruits, and a few starchy vegetables like sweet potatoes. I believe that a very low carbohydrate diet can help the everyday person lose weight, a moderately low carbohydrate diet can enhance performance in athletes by teaching the body to burn fat as energy; but needs to be individualized because of the dangers of going too far. As a metaphor, we talked about how alcohol and dark chocolate in moderation are good, but not too much. I personally believe a low carbohydrate diet is good, with proper carbohydrate choices; however going too far or too low-carbohydrate is potentially dangerous.
