Total Rating
5.6
out of 10
3.9
out of 10
Metabolic Health
7
Moderately improves metabolic markers but lacks robust long-term trial evidence for comprehensive metabolic health benefits.
4
Limited short-term metabolic benefits but risks nutrient deficiencies and unsustainable practices.
Micronutrients
3
Lacks essential micronutrients like B12, D, and iodine without supplementation, risking chronic deficiencies.
3
Severely limits essential micronutrients like B12, iron, and calcium through restrictive food choices.
Nutrient Density
6
Provides moderate nutrient density with plant-based focus but lacks optimal phytonutrient diversity and may rely on processed foods.
5
Limited phytonutrient diversity and reliance on low-calorie, nutrient-dense but restrictive food selections.
Overall Health
7
Offers substantial benefits for chronic disease prevention and metabolic health but requires careful planning to avoid nutrient deficiencies.
4
Limited nutritional adequacy and potential for nutrient deficiencies hinder long-term health benefits.
Sustainability
6
Limited flexibility and potential for strictness may hinder long-term adherence and practicality.
3
Requires strict meal planning, limited food choices, and potential for psychological stress, making long-term adherence challenging.
Lifestyle Fit
4
Requires significant lifestyle adjustments and may conflict with social and travel flexibility.
3
Severely restricts social and travel flexibility, requires significant planning, and lacks adaptability to real-world routines.
Practicality
5
Requires specialized ingredients and preparation methods that limit accessibility and affordability for most people.
5
Limited food variety and strict meal timing reduce long-term adherence and real-world feasibility.
Appetite Control
6
Provides moderate fiber and protein but may lack balance in macronutrient distribution and risk of refined carbohydrate reliance.
6
Moderate satiety from fiber and water content, but limited protein and potential for hunger due to restrictive nature.
Fat Quality
6
Relies heavily on ALA without EPA/DHA, limiting omega-3 benefits despite whole-food fat sources.
4
Lacks sufficient healthy fats and has an imbalanced omega-3 to omega-6 ratio.
Fiber Intake
7
Provides adequate fiber quantity but may lack diversity in fiber types and practical tolerance for some individuals.
4
Provides limited fiber quantity and poor diversity, risking inadequate gut and metabolic support.
Gut Health
6
Provides adequate fiber and plant diversity but lacks specific fermented foods and may risk digestive discomfort without tailored adjustments.
2
Severely limits fiber diversity, excludes prebiotics and fermented foods, and risks digestive distress due to restrictive nature.
Hormonal Support
5
Limited micronutrient density and potential deficiencies in hormone-synthesizing nutrients like B12 and zinc may hinder hormonal balance.
3
Severe calorie restriction and nutrient deficiencies disrupt hormonal balance, elevating cortisol and impairing sex and thyroid hormones.
Macro Balance
6
Provides adequate protein and fiber but may lack flexibility in fat and carb adjustments for diverse goals.
3
Severely restricts protein and carbohydrates, leading to metabolic stress and poor long-term adherence.
Protein Quality
6
Provides adequate but less optimal plant-based protein with potential gaps in amino acid balance and digestibility.
6
Provides adequate animal-based protein but lacks balanced amino acid distribution and nutrient-dense food matrix.
Taste
5
Limited flavor variety and potential for blandness may hinder long-term adherence.
4
Limited flavor variety and reliance on tart grapefruit may reduce meal enjoyment and long-term adherence.
Body Composition
5
Limited protein adequacy and potential muscle loss risk under restrictive plant-based framework.
5
Promotes short-term fat loss but risks muscle loss and lacks sufficient protein support for lean mass preservation.
Energy Balance
6
Offers moderate satiety from plant-based foods but lacks structured calorie tracking or flexibility for precise energy management.
5
Provides limited structure for calorie control but risks overeating due to restrictive food choices and poor satiety.
Lean Mass
5
Limited protein adequacy and energy availability may hinder muscle preservation during caloric restriction.
3
Severely restricts protein and energy intake, increasing muscle catabolism during fat loss.
Athletic Support
5
Provides adequate macronutrients but risks nutrient deficiencies and may struggle with energy availability for high-intensity training.
3
Severely restricts calories and carbohydrates, compromising energy availability and recovery while lacking balanced macronutrients and practical timing strategies.
Weight Loss
6
Provides moderate calorie deficit potential but lacks robust long-term evidence for sustained fat loss compared to other structured diets.
5
Limited evidence for sustained fat loss, with risks of poor adherence and potential muscle loss.
