Solution
Research Question (2 points): Does the intake of carbohydrates have an effect on cognitive performance, specifically in areas of memory, attention, and reaction time?
Hypotheses (2 points): Increased carbohydrate consumption will improve cognitive performance. Alternatively, carbohydrate consumption has no effect on cognitive performance.
Participants (3 points): The study will recruit healthy adults aged 18-65, of both genders, and from diverse ethnic backgrounds. The rationale is to have a representative sample of the general population.
Experimental Design (3 points): The study will be a randomized controlled trial, with the independent variable being carbohydrate intake and the dependent variable being cognitive performance. This design allows for a clear cause-effect relationship to be established.
Carbohydrate Manipulation (2 points): Participants will be randomly assigned to follow a high-carbohydrate diet or a control diet. Carbohydrate consumption will be monitored through food diaries.
Control Variables (3 points): Sleep, physical activity, and overall nutritional intake will be controlled for by having participants maintain regular sleep and exercise schedules and by monitoring other aspects of diet.
Measurement of Cognitive Performance (3 points): Cognitive performance will be measured using standardized cognitive tests that assess memory, attention, and reaction time. These measures align with the research question and are widely used in cognitive research.
Data Collection (3 points): Data will be collected through food diaries and cognitive tests. Data collection will occur at baseline and after 4 weeks of the diet intervention.
Ethical Considerations (2 points): Participants will provide informed consent, and their data will be kept confidential. Their well-being will be monitored throughout the study.
Data Analysis (1 point): Differences in cognitive performance between the high-carbohydrate and control groups will be compared using t-tests.
Part C. Format your proposal (2 points): The proposal is clearly organized, with each required element labeled and separated into its own paragraph. The proposal is over 250 words and contains no typos or grammatical errors.

Well trained individuals may utilise less glycogen/carbohydrate for performance. But in reality the fitter we are and the faster we want to go, we continue to push the intensity, as a result glycogen depletion is still a very real thing even for the most highly trained individuals, hence peak performance determined by the ability to utilise carbs and fats effectively.
From a diet history you estimate that Harry is consuming ~13 000kJ and he wants to reduce his energy intake to lose weight. He is consuming ~40% of his energy from fat (150g), ~40 % of energy from carbohydrate (300g) and ~20% of energy from protein (150g). Which strategy would be the most effective in reducing his energy intake?Group of answer choicesReduce his carbohydrate intake by 75gChange his AMDR to - 15% of his energy from fat (30g), 50% of energy from carbohydrate (200g) and 35 % of energy from protein (140g) (low fat, high protein, moderate carb)Reduce his fat intake by 60gChange his AMDR to - 25% of his energy from fat (50g), 25 % of energy from carbohydrate (100g) and 50 % of energy from protein (200g) (low carb, high protein, moderate fat )
