6.8
out of 10
Metabolic Health
5
Provides moderate protein and fiber but risks metabolic stress from processed ingredients and inconsistent nutrient balance.
7
Offers moderate improvements in blood sugar and lipid markers but lacks robust evidence for sustained metabolic benefits compared to other dietary patterns.
Micronutrients
5
Provides some essential micronutrients but lacks consistent coverage of critical vitamins and minerals like B12, D, and iodine without supplementation.
7
Provides adequate micronutrient coverage on non-fasting days but risks deficiencies on fasting days without careful planning.
Nutrient Density
5
Relies heavily on processed foods and limited phytonutrient diversity, reducing nutrient efficiency per calorie.
6
Offers moderate nutrient density with potential for improvement through whole foods and phytonutrient variety.
Overall Health
5
Provides moderate nutritional balance but lacks robust evidence for long-term disease prevention and sustainability.
7
Offers moderate benefits for metabolic health and disease risk reduction but lacks robust long-term population data and may pose nutrient gaps if not carefully managed.
Sustainability
4
Limited flexibility and restrictive structure hinder long-term adherence and practicality.
7
Offers moderate flexibility and practicality but may challenge adherence due to fasting days and potential psychological stress.
Lifestyle Fit
7
Offers convenient, flexible meal options with moderate social compatibility but limited adaptability to diverse dietary needs and preferences.
7
Offers moderate flexibility for social and travel scenarios but requires planning for fasting days.
Practicality
6
Relatively affordable and simple to plan but limited by strict timing and reliance on specific chain items.
8
Offers flexibility with minimal cost, accessibility, and preparation effort while allowing normal eating on most days.
Appetite Control
7
Provides moderate protein and fiber but may lack consistent energy density and glycemic stability for optimal appetite control.
7
Balances satiety through moderate protein and fiber intake but may struggle with hunger management on restricted days without careful food choices.
Fat Quality
5
Provides moderate intake of unsaturated fats but lacks emphasis on omega-3 adequacy and may include processed saturated fats.
6
Provides moderate emphasis on healthy fats but lacks structured guidance on omega-3 balance and saturated fat sources.
Fiber Intake
5
Provides moderate fiber from whole grains and vegetables but lacks diversity and sufficient quantity for optimal gut and metabolic health.
6
Provides variable fiber intake depending on non-fasting day choices, but lacks structured fiber optimization.
Gut Health
3
Limited fiber diversity and reliance on processed foods hinder microbiome health and digestive tolerance.
5
Limited support for gut microbiome diversity and digestive health due to restricted fiber and lack of prebiotic/fermented food emphasis.
Hormonal Support
6
Provides moderate protein and fiber for satiety but may lack sufficient micronutrients and risk cortisol elevation with strict calorie restriction.
7
Moderately supports hormonal balance with intermittent fasting benefits but may elevate cortisol in some individuals.
Macro Balance
5
Provides adequate protein and fiber but severely restricts fats and may lack optimal carbohydrate diversity.
7
Offers flexibility for macro adjustment but lacks structured guidance on optimal ratios for most individuals.
Protein Quality
6
Provides adequate but not optimal high-quality protein from lean meats, though total intake may fall short for muscle preservation in active individuals.
6
Provides adequate protein on non-fasting days but risks insufficiency on restricted days without deliberate intake management.
Taste
2
Lacks flavor variety and satiety, leading to poor long-term adherence.
7
Offers moderate variety and adaptability but requires careful meal planning to maintain palatability on restricted days.
Body Composition
5
Limited protein and potential for muscle loss despite fat loss.
7
Moderately effective for fat loss with reasonable lean mass preservation when protein intake is adequate.
Energy Balance
5
Provides structured calorie control but lacks satiety, flexibility, and robust evidence for long-term energy management.
6
Provides structured calorie control on fasting days but may struggle with satiety, consistency, and flexibility for varied goals.
Lean Mass
4
Limited protein intake and potential calorie deficit may hinder muscle retention during weight loss.
7
Moderately supports lean mass retention when protein intake is adequate and energy balance is maintained.
Athletic Support
6
Provides moderate macronutrient variety but lacks structured timing, hydration focus, and consistent micronutrient coverage for optimal athletic performance.
6
May support energy and recovery if well-managed but risks underfueling and nutrient gaps without strict adherence.
Weight Loss
5
Provides moderate calorie control but lacks robust evidence for sustained fat loss and may encourage poor adherence due to limited variety and potential nutrient imbalances.
7
Promotes moderate calorie deficit with flexible eating patterns but lacks robust evidence for sustained fat loss compared to other structured diets.
