Metabolic Health ⓘ
2
Lacks robust evidence to support improvements in metabolic health markers or cardiometabolic risk factors.
7
Moderately improves blood sugar and lipid markers but may elevate LDL and inflammation risks.
Micronutrients ⓘ
3
Fails to consistently meet essential micronutrient requirements without relying on supplementation or fortified foods.
5
Provides adequate protein and fat but risks deficiencies in fiber, vitamin C, and certain minerals due to restricted plant foods.
Nutrient Density ⓘ
4
Relies on restrictive food choices with limited phytonutrient diversity and nutrient density per calorie.
5
Relies heavily on calorie-dense, low-nutrient foods with limited phytonutrient diversity.
Overall Health ⓘ
2
Lacks scientific foundation, promotes nutrient deficiencies, and fails to address chronic disease prevention or long-term sustainability.
6
Offers short-term metabolic benefits but risks nutrient deficiencies and cardiovascular concerns with long-term adherence.
Sustainability ⓘ
3
Its strict blood-type-specific restrictions limit flexibility, practicality, and long-term adherence due to rigid food exclusions and lack of scientific support for sustained compliance.
6
Moderate sustainability due to strict initial phases and potential for social and psychological challenges, but offers flexibility in later stages.
Lifestyle Fit ⓘ
3
Severely restricts social interactions and travel flexibility, requiring rigid meal planning and limiting adaptability to real-world demands.
5
Limited flexibility in social settings and travel, requiring significant planning and adherence to restrictive food choices.
Practicality ⓘ
2
Requires strict, costly, and geographically limited food choices with minimal real-world adherence evidence.
6
Requires significant planning, specialty foods, and strict meal structure, limiting accessibility and affordability for many.
Appetite Control ⓘ
4
Limited protein and fiber consistency across blood types may lead to variable satiety and potential cravings.
7
Provides adequate protein and fat for satiety but may induce initial carb cravings and require strict adherence to maintain appetite control.
Fat Quality ⓘ
5
Limited emphasis on omega-3 balance and whole-food unsaturated fats, with insufficient scientific support for fat quality claims.
6
Prioritizes saturated fats and omega-6 over unsaturated fats, risking cardiovascular and inflammatory risks.
Fiber Intake ⓘ
5
Provides variable fiber adequacy across blood types but lacks consistent diversity and robust evidence for functional outcomes.
3
Severely restricts high-fiber plant foods, leading to inadequate fiber quantity and diversity.
Gut Health ⓘ
3
Limited fiber variety and lack of prebiotic/fermented food emphasis hinder microbiome diversity and digestive support.
4
Limited fiber and prebiotic intake may hinder microbiome diversity and digestive tolerance.
Hormonal Support ⓘ
3
Lacks scientific evidence for hormonal regulation, relying on unproven blood type theories rather than physiological mechanisms.
5
Limited micronutrient diversity and potential sex hormone imbalances due to high saturated fat and restricted food groups.
Macro Balance ⓘ
2
Lacks evidence-based macronutrient distribution and rigidly adheres to unscientific blood-type-specific ratios.
6
Provides adequate protein and fat but risks metabolic rigidity and reduced carbohydrate flexibility without clear evidence-based justification.
Protein Quality ⓘ
3
Relies on unproven blood type-specific protein recommendations, leading to inconsistent amino acid profiles and potential insufficiency in key populations.
8
Provides high-quality animal proteins with adequate amino acids and digestibility, but may lack optimal distribution and micronutrient balance in restrictive phases.
Taste ⓘ
4
Limited variety and restrictive food choices often lead to repetitive, bland meals that reduce long-term enjoyment and adherence.
6
Offers flavorful proteins and fats but may lack variety and adaptability due to carb restrictions.
Body Composition ⓘ
2
Lacks scientific evidence for improving fat-to-muscle ratio and risks inadequate protein for lean mass preservation.
7
Promotes fat loss with moderate lean mass preservation but risks muscle loss if protein intake is insufficient.
Energy Balance ⓘ
3
Lacks structured calorie control, satiety guidance, and flexibility for energy goals, with limited scientific support for consistent energy management.
6
Provides moderate calorie control through low-carb structure but lacks flexibility for surplus and may induce binge cycles.
Lean Mass ⓘ
3
Lacks sufficient protein adequacy and energy availability to reliably support lean mass preservation during caloric restriction.
6
Moderately supports lean mass preservation during weight loss but may compromise muscle retention due to high fat intake and potential energy deficits.
Athletic Support ⓘ
3
Lacks scientific foundation, may restrict essential nutrients, and fails to address practical energy and recovery needs for athletes.
5
Provides adequate protein and fat but lacks sufficient carbohydrates for optimal energy and recovery in most athletic contexts.
Weight Loss ⓘ
2
Lacks scientific evidence for sustained calorie deficit or fat loss, with restrictive food rules that hinder long-term adherence and metabolic benefits.
6
Promotes initial weight loss but lacks long-term sustainability and may lead to metabolic adaptation and weight regain.
