Introduction
There is plenty of disunion on what kind of diet is the best for treating obesity and encouraging weight loss. Different diets emphasize protein, others emphasize carbohydrates and yet other focus on fat. Research shows that diets that cause weight loss successfully are made of fat, protein, and carbohydrate compositions. These diets should carry beneficial effects for cardiovascular disease and diabetes (Sacks et al., 2009). The diet can be customized according to the individual preferences for the best results in weight loss.
Karen has been more tired and irritable lately because of the changes she has made in her diet. She has eliminated all carbs from her diet. As Hu et al. (2012) states, the dietary intake has an impact on multiple body systems. Several studies reflect that low-carbohydrate diets can lead to mood changes. It is seen that low-carbohydrate diets are often high in fat, and those could lead to other health issues. If one has cut too many carbs from their diet, their cognitive skills suffer. Certain percentage of carbs are essential to help the body burn fat. Karen should follow a diet made of 25% protein, 25% fat, and 50% Carbohydrates from unprocessed foods (Carbohydrates in human nutrition, 2013). The endurance capacity of an individual with high carbohydrate diet is superior to those with low card diet. A diet based on just fat and protein can lower Karen’s capacity to exercise. When Muscle glycogen concentration reaches lower values, fatigue occurs, and one feels tired. A high carbohydrate diet improves muscle glycogen and heels faster recovery from exhaustive exercise. Why Karen has a strange odor in her breath is because as her body burns fat, certain chemicals called ketones get released and causes the odor. According to Mann (2015), as Carbohydrates are not advisable for the body, it starts using fats and proteins as sources of energy. Thus, people on low carb diet soften face issues of breath problems. The bottom line is that Karen must reconsider her diet program and ensure that she eats healthy and mutinous foods.
