Total Rating
6.2
out of 10
6.4
out of 10
Metabolic Health
6
May improve short-term insulin sensitivity but risks elevated LDL and inflammation with excessive animal protein.
7
Improves blood sugar and lipid profiles but varies based on dietary quality and individual response.
Micronutrients
6
Provides adequate protein but may lack diversity in micronutrient sources, risking deficiencies in vitamin D, iodine, and certain plant-based iron unless fortified.
6
Provides adequate protein and fat but may lack sufficient vitamin D, calcium, and iodine without fortified foods or supplements.
Nutrient Density
7
Provides dense protein and some micronutrients but lacks phytonutrient diversity and may rely on processed foods.
6
Provides adequate protein and fat but lacks phytonutrient diversity and may prioritize calorie-dense foods over nutrient-rich plant sources.
Overall Health
5
May offer short-term satiety but carries risks of cardiovascular strain and nutrient imbalances with long-term adherence.
7
Offers metabolic benefits but risks nutrient deficiencies and long-term sustainability challenges.
Sustainability
6
Moderate sustainability due to potential cost, social challenges, and long-term adherence variability.
6
Balances flexibility with potential for dietary restrictions and social challenges.
Lifestyle Fit
7
Offers moderate flexibility for daily routines but may strain social adaptability and long-term adherence due to rigid protein focus.
6
Offers moderate flexibility but faces challenges in social integration and travel adaptability.
Practicality
7
Requires moderate cost and effort for meal prep but offers accessible protein sources and flexibility in daily routines.
7
Offers accessible, affordable staples with moderate meal planning effort but may require adjustments for long-term sustainability.
Appetite Control
8
Effectively enhances satiety through protein and moderate fiber, but may lack sustained satiety without balanced fat and complex carb inclusion.
7
Moderately effective in reducing hunger through protein and fat satiety, but may lack fiber and risk overeating high-energy-density foods.
Fat Quality
6
Provides moderate healthy fats but may lack optimal omega-3 to omega-6 balance and risk excessive saturated fats from animal protein sources.
7
Provides moderate healthy fats but risks poor omega-3 to omega-6 balance and excessive saturated fats in many versions.
Fiber Intake
3
Typically lacks sufficient fiber diversity and quantity to support gut and metabolic health.
5
Provides moderate fiber from vegetables but often falls short of recommended quantities and lacks diversity in fiber types.
Gut Health
5
Limited fiber and fermented food inclusion may hinder microbiome diversity and digestive balance.
5
Limited fiber and prebiotic content may hinder microbiome diversity and digestive health.
Hormonal Support
6
Provides moderate support for insulin and satiety hormones but may disrupt cortisol and sex hormones with excessive protein intake or insufficient micronutrients.
6
Moderately supports hormonal balance but risks cortisol elevation and micronutrient deficiencies if not carefully structured.
Macro Balance
6
Provides adequate protein for muscle maintenance but risks imbalance if carbs/fats are overly restricted.
6
Provides adequate protein and fat but risks carbohydrate restriction without clear metabolic benefit.
Protein Quality
7
Provides adequate high-quality protein from animal sources but may lack amino acid diversity if not balanced.
7
Provides adequate high-quality protein from animal sources but may lack optimal amino acid balance and nutrient density in plant-based variations.
Taste
7
Offers satisfying flavors and satiety but may lack variety unless carefully planned.
7
Offers moderate flavor variety and adaptability but may lack complexity compared to more diverse diets.
Body Composition
7
Effectively supports lean mass preservation and fat loss when balanced with adequate calories and resistance training.
7
Effectively promotes fat loss with moderate lean mass preservation when protein adequacy is ensured.
Energy Balance
7
Provides moderate control over calorie intake through satiety from protein but lacks structured portion guidance and may encourage overconsumption of calorie-dense foods.
7
Provides moderate control over calorie intake through satiety from protein/fat but lacks structured portion guidance and risks hidden calories without tracking.
Lean Mass
7
Moderately supports lean mass retention during weight loss but may lack optimal protein distribution and energy balance in real-world adherence.
7
Moderately supports lean mass retention during weight loss when protein intake is adequate and energy balance is maintained.
Athletic Support
6
Provides adequate protein for muscle repair but may lack sufficient carbohydrates for endurance and may compromise micronutrient density if not balanced.
5
Limited carbohydrate availability may hinder high-intensity performance and recovery, though adequate protein and fats can support some athletic demands.
Weight Loss
7
Provides moderate short-term weight loss with sustainable calorie deficit but limited long-term fat loss evidence and potential adherence challenges.
7
Effectively creates calorie deficit and supports fat loss but faces sustainability challenges and potential metabolic adaptation risks.
