out of 10
Metabolic Health
6
May modestly improve some metabolic markers but lacks robust long-term evidence and risks nutrient deficiencies under strict plant-based constraints.
7
Moderately improves blood sugar and lipid profiles but may lack long-term metabolic flexibility and inflammatory benefits.
Micronutrients
3
Fails to reliably provide essential micronutrients like B12, vitamin D, and iodine without supplementation.
7
Provides adequate micronutrient coverage through diverse animal and plant sources but may risk deficiencies in vitamin D or iodine without supplementation.
Nutrient Density
6
Provides moderate phytonutrient diversity but may lack optimal bioavailability and variety in whole foods.
7
Balances nutrient-rich proteins and fats but limits phytonutrient diversity and may rely on processed foods.
Overall Health
7
Promotes nutrient-rich plant foods but risks deficiencies without supplementation and may lack long-term sustainability.
7
Balances moderate protein and healthy fats with some nutrient gaps but lacks robust long-term population-level evidence for chronic disease prevention.
Sustainability
4
Requires strict plant-based adherence with limited flexibility and potential for social and psychological challenges.
6
Moderate flexibility in maintenance phase but strict initial phases reduce long-term adherence potential.
Lifestyle Fit
4
Requires strict adherence and limited flexibility, complicating social interactions and travel while demanding significant time and planning.
7
Offers moderate flexibility for social and travel scenarios but requires initial strictness that may challenge long-term adherence.
Practicality
6
Requires moderate cost and effort for meal prep but offers accessible staples for long-term adherence.
7
Offers balanced affordability and accessibility but requires structured meal planning and initial phase restrictions.
Appetite Control
6
Provides adequate protein and fiber but may induce cravings due to restrictive phases and limited food variety.
6
Balances protein and fiber to moderate hunger but may induce cravings during restrictive phases.
Fat Quality
7
Emphasizes whole-food healthy fats but lacks explicit focus on omega-3 to omega-6 balance and saturated fat context.
8
Emphasizes whole-food unsaturated fats and omega-3s from fish but may lack sufficient omega-3 to omega-6 balance in some variations.
Fiber Intake
6
Provides adequate fiber quantity but may lack diversity in fiber types and practical long-term adherence.
7
Provides moderate fiber from whole foods but falls short of optimal diversity and quantity compared to plant-based diets.
Gut Health
6
Provides moderate fiber and plant diversity but lacks fermented foods and evidence for microbiome benefits.
5
Limited fiber and plant diversity, with potential digestive challenges but some fermented food inclusion.
Hormonal Support
5
Provides some fiber and plant-based nutrients but risks hormonal imbalance due to low-fat, high-carb composition and potential micronutrient deficiencies.
7
Moderately supports hormone balance through balanced macronutrients but lacks robust evidence on specific hormonal outcomes.
Macro Balance
5
Limited protein and fat adequacy with rigid ratios.
7
Provides balanced protein and healthy fats but restricts carbohydrates too rigidly for long-term adaptability.
Protein Quality
5
Provides adequate protein quantity but lacks optimal amino acid balance, digestibility, and distribution for maximal recovery and satiety.
7
Provides adequate high-quality animal proteins but may lack optimal amino acid balance and distribution in some phases.
Taste
5
Limited flavor variety and restrictive food choices may lead to unappealing meals, reducing long-term adherence.
7
Offers flavorful proteins and fats with seasoning options but may lack variety and adaptability in strict phases.
Body Composition
5
Limited protein adequacy and risk of lean mass loss under strict plant-based constraints.
7
Effectively supports fat loss while preserving lean mass through balanced protein and moderate caloric restriction, but lacks robust long-term evidence for sustained body composition improvements.
Energy Balance
5
Provides some structure for calorie control but lacks flexibility and proven consistency for long-term energy management.
7
Provides structured macronutrient guidance but lacks explicit calorie tracking and may lead to inconsistent energy intake due to phased restrictions.
Lean Mass
3
Severely restricts protein and energy intake, risking significant lean mass loss during calorie deficit.
6
Provides moderate protein but may compromise energy availability during fat loss, risking muscle catabolism.
Athletic Support
6
Provides adequate macronutrients but risks underfueling and micronutrient deficiencies if not meticulously planned.
5
Provides moderate protein and healthy fats but may inadequately support high-intensity energy needs and glycogen replenishment for athletes.
Weight Loss
6
Promotes calorie deficit through plant-based foods but lacks long-term evidence for sustained fat loss and may risk poor adherence due to restrictive nature.
7
Provides moderate calorie deficit and fat loss potential with structured phases but faces sustainability challenges and variable long-term adherence.
