out of 10
3.9
out of 10
Metabolic Health
5
Limited evidence supports metabolic improvements, but potential benefits from polyphenols are offset by lack of comprehensive research and possible nutrient imbalances.
4
Limited short-term metabolic benefits but risks nutrient deficiencies and unsustainable practices.
Micronutrients
3
Relies heavily on limited food sources, risking deficiencies in B12, vitamin D, and other critical nutrients without fortification or supplementation.
3
Severely limits essential micronutrients like B12, iron, and calcium through restrictive food choices.
Nutrient Density
5
Limited phytonutrient diversity and potential nutrient gaps despite some antioxidant benefits.
5
Limited phytonutrient diversity and reliance on low-calorie, nutrient-dense but restrictive food selections.
Overall Health
3
Severely restricts essential nutrients and lacks robust evidence for long-term health benefits.
4
Limited nutritional adequacy and potential for nutrient deficiencies hinder long-term health benefits.
Sustainability
3
Requires restrictive food choices and lacks flexibility, making long-term adherence difficult.
3
Requires strict meal planning, limited food choices, and potential for psychological stress, making long-term adherence challenging.
Lifestyle Fit
5
Limited social flexibility and travel adaptability hinder real-world adherence.
3
Severely restricts social and travel flexibility, requires significant planning, and lacks adaptability to real-world routines.
Practicality
5
Requires significant dietary restriction and limited variety, making long-term adherence challenging despite accessible and affordable grapes.
5
Limited food variety and strict meal timing reduce long-term adherence and real-world feasibility.
Appetite Control
5
Limited protein and fiber content may lead to hunger, but low energy density could support satiety.
6
Moderate satiety from fiber and water content, but limited protein and potential for hunger due to restrictive nature.
Fat Quality
4
Lacks sufficient healthy fats and has an imbalanced omega-3 to omega-6 ratio.
4
Lacks sufficient healthy fats and has an imbalanced omega-3 to omega-6 ratio.
Fiber Intake
3
Relies on low-fiber fruits with limited diversity and fails to meet recommended fiber intake for optimal gut and metabolic health.
4
Provides limited fiber quantity and poor diversity, risking inadequate gut and metabolic support.
Gut Health
4
Limited fiber diversity and potential digestive discomfort due to high sugar content reduce its effectiveness for gut health.
2
Severely limits fiber diversity, excludes prebiotics and fermented foods, and risks digestive distress due to restrictive nature.
Hormonal Support
6
Provides moderate support for insulin regulation and satiety but may lack sufficient micronutrients and risk cortisol elevation with strict calorie restriction.
3
Severe calorie restriction and nutrient deficiencies disrupt hormonal balance, elevating cortisol and impairing sex and thyroid hormones.
Macro Balance
6
Provides moderate protein and fat but lacks adaptability and clear evidence for optimal macro ratios.
3
Severely restricts protein and carbohydrates, leading to metabolic stress and poor long-term adherence.
Protein Quality
3
Relies on low-protein, incomplete plant sources with insufficient amino acids and poor digestibility.
6
Provides adequate animal-based protein but lacks balanced amino acid distribution and nutrient-dense food matrix.
Taste
6
Offers moderate flavor and satiety but limited variety and adaptability.
4
Limited flavor variety and reliance on tart grapefruit may reduce meal enjoyment and long-term adherence.
Body Composition
4
Limited protein intake and insufficient evidence for fat loss while preserving lean mass.
5
Promotes short-term fat loss but risks muscle loss and lacks sufficient protein support for lean mass preservation.
Energy Balance
4
Limited structure for calorie control and variable satiety impact due to high sugar content and lack of clear portion guidance.
5
Provides limited structure for calorie control but risks overeating due to restrictive food choices and poor satiety.
Lean Mass
3
Severely limits protein and energy intake, risking significant lean mass loss during calorie restriction.
3
Severely restricts protein and energy intake, increasing muscle catabolism during fat loss.
Athletic Support
5
Limited macronutrient variety and potential micronutrient deficiencies may hinder sustained athletic performance and recovery.
3
Severely restricts calories and carbohydrates, compromising energy availability and recovery while lacking balanced macronutrients and practical timing strategies.
Weight Loss
5
Limited evidence supports sustained fat loss, with potential for short-term calorie deficit but questionable long-term sustainability and metabolic effects.
5
Limited evidence for sustained fat loss, with risks of poor adherence and potential muscle loss.
