Metabolic Health
7
Moderately improves blood sugar and lipid profiles but may lack long-term metabolic flexibility and inflammatory benefits.
7
Moderately improves blood sugar and lipid markers but may elevate LDL and inflammation risks.
Micronutrients
7
Provides adequate micronutrient coverage through diverse animal and plant sources but may risk deficiencies in vitamin D or iodine without supplementation.
5
Provides adequate protein and fat but risks deficiencies in fiber, vitamin C, and certain minerals due to restricted plant foods.
Nutrient Density
7
Balances nutrient-rich proteins and fats but limits phytonutrient diversity and may rely on processed foods.
5
Relies heavily on calorie-dense, low-nutrient foods with limited phytonutrient diversity.
Overall Health
7
Balances moderate protein and healthy fats with some nutrient gaps but lacks robust long-term population-level evidence for chronic disease prevention.
6
Offers short-term metabolic benefits but risks nutrient deficiencies and cardiovascular concerns with long-term adherence.
Sustainability
6
Moderate flexibility in maintenance phase but strict initial phases reduce long-term adherence potential.
6
Moderate sustainability due to strict initial phases and potential for social and psychological challenges, but offers flexibility in later stages.
Lifestyle Fit
7
Offers moderate flexibility for social and travel scenarios but requires initial strictness that may challenge long-term adherence.
5
Limited flexibility in social settings and travel, requiring significant planning and adherence to restrictive food choices.
Practicality
7
Offers balanced affordability and accessibility but requires structured meal planning and initial phase restrictions.
6
Requires significant planning, specialty foods, and strict meal structure, limiting accessibility and affordability for many.
Appetite Control
6
Balances protein and fiber to moderate hunger but may induce cravings during restrictive phases.
7
Provides adequate protein and fat for satiety but may induce initial carb cravings and require strict adherence to maintain appetite control.
Fat Quality
8
Emphasizes whole-food unsaturated fats and omega-3s from fish but may lack sufficient omega-3 to omega-6 balance in some variations.
6
Prioritizes saturated fats and omega-6 over unsaturated fats, risking cardiovascular and inflammatory risks.
Fiber Intake
7
Provides moderate fiber from whole foods but falls short of optimal diversity and quantity compared to plant-based diets.
3
Severely restricts high-fiber plant foods, leading to inadequate fiber quantity and diversity.
Gut Health
5
Limited fiber and plant diversity, with potential digestive challenges but some fermented food inclusion.
4
Limited fiber and prebiotic intake may hinder microbiome diversity and digestive tolerance.
Hormonal Support
7
Moderately supports hormone balance through balanced macronutrients but lacks robust evidence on specific hormonal outcomes.
5
Limited micronutrient diversity and potential sex hormone imbalances due to high saturated fat and restricted food groups.
Macro Balance
7
Provides balanced protein and healthy fats but restricts carbohydrates too rigidly for long-term adaptability.
6
Provides adequate protein and fat but risks metabolic rigidity and reduced carbohydrate flexibility without clear evidence-based justification.
Protein Quality
7
Provides adequate high-quality animal proteins but may lack optimal amino acid balance and distribution in some phases.
8
Provides high-quality animal proteins with adequate amino acids and digestibility, but may lack optimal distribution and micronutrient balance in restrictive phases.
Taste
7
Offers flavorful proteins and fats with seasoning options but may lack variety and adaptability in strict phases.
6
Offers flavorful proteins and fats but may lack variety and adaptability due to carb restrictions.
Body Composition
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.
7
Promotes fat loss with moderate lean mass preservation but risks muscle loss if protein intake is insufficient.
Energy Balance
7
Provides structured macronutrient guidance but lacks explicit calorie tracking and may lead to inconsistent energy intake due to phased restrictions.
6
Provides moderate calorie control through low-carb structure but lacks flexibility for surplus and may induce binge cycles.
Lean Mass
6
Provides moderate protein but may compromise energy availability during fat loss, risking muscle catabolism.
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
5
Provides moderate protein and healthy fats but may inadequately support high-intensity energy needs and glycogen replenishment for athletes.
5
Provides adequate protein and fat but lacks sufficient carbohydrates for optimal energy and recovery in most athletic contexts.
Weight Loss
7
Provides moderate calorie deficit and fat loss potential with structured phases but faces sustainability challenges and variable long-term adherence.
6
Promotes initial weight loss but lacks long-term sustainability and may lead to metabolic adaptation and weight regain.
