What is the purpose of this trial?

This trial tests how dietary changes might help with memory problems in overweight adults. Participants will either consume a berry fruit powder and follow a low-carbohydrate diet (nutritional ketosis) or take a placebo powder with a higher carbohydrate diet. The goal is to determine if these changes can improve memory issues. It suits those who are overweight and have noticed memory problems but do not have diabetes or other major health issues. As an unphased trial, it provides a unique opportunity to explore innovative dietary approaches to enhance memory health.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that berry-based supplements and foods can improve brain function, including memory. Participants who took these supplements often experienced enhanced memory and brain activity, with no major safety concerns reported.

Similarly, the ketogenic diet, low in carbs and high in fats, has been linked to improved memory in individuals with mild memory issues. This suggests it might be safe, though some studies recommend cautious use. No major harmful side effects have been reported.

Overall, both berry fruit powder and the ketogenic diet appear well-tolerated according to research. No significant negative effects have been consistently reported. However, with any dietary change, individuals should monitor their body's reactions. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for memory problems in overweight adults because they explore natural and dietary approaches that differ from traditional medications. One treatment uses whole fruit berry powder, which is rich in antioxidants that might protect brain cells and improve memory. The other treatment involves nutritional ketosis, a low carbohydrate diet that could enhance brain function by using ketones as an alternative energy source. Unlike standard treatments that often focus on pharmaceuticals, these interventions offer a more holistic approach, potentially with fewer side effects.

What evidence suggests that this trial's treatments could be effective for memory problems?

Research has shown that eating very few carbohydrates can improve memory in older adults, especially those at risk of memory problems. One study found that reducing carbs, even for a short period, boosted memory. Additionally, foods and supplements made from berries have enhanced brain function and memory. Several studies have found that adding berries to the diet can improve thinking skills. This trial will compare different interventions: one group will receive a combination of berry fruit powder and a low-carb diet, while another group will receive a placebo powder and a higher carbohydrate diet. These findings suggest that combining berry fruit powder with a low-carb diet might help with memory issues in overweight adults. ^{1 3 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Berry fruit powder OR nutritional ketosis
• Placebo powder OR higher carbohydrate

Trial Overview The study is testing the effects of a berry fruit powder that has more carbohydrates versus a nutritional ketosis approach on cognitive function in people concerned about their weight and memory. Some participants will receive a placebo powder instead.

Group I: Active supplement, low carbohydrate Active Control 1 Intervention

Whole fruit berry powder, low carbohydrate diet

Group II: Placebo, Control Placebo Group 1 Intervention

placebo powder, higher carbohydrate diet

The Mediterranean ketogenic nutrition (MKN) program that included motivational interviewing and behavior change techniques led to higher participant retention (82%) and attendance (91%) compared to a standard education program, indicating it may be more effective in engaging older adults with memory concerns.

Participants in the MKN Adherence program showed better adherence to the diet and some clinical benefits, although these benefits were less pronounced at the 3-month follow-up, suggesting that ongoing support may be necessary for sustained effects.

A phase I/II clinical trial involving 27 patients with mild cognitive impairment or early Alzheimer's disease tested a modified Atkins diet (MAD) to induce ketone production, which may provide an alternative energy source for the brain.

Preliminary results showed that participants in the MAD group who produced trace amounts of ketones experienced a significant improvement in memory scores and reported increased energy, suggesting that even small amounts of ketones could benefit cognitive function in early Alzheimer's disease.
