Metabolic Health ⓘ
7
Improves insulin sensitivity and lipid profiles but shows variable effects on inflammation and long-term metabolic sustainability.
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
May lead to chronic deficiencies in B12, iron, and other nutrients if not paired with nutrient-dense foods.
7
Provides adequate micronutrient coverage on non-fasting days but risks deficiencies on fasting days without careful planning.
Nutrient Density ⓘ
6
Provides moderate nutrient density when paired with whole foods but lacks inherent diversity and bioavailability optimization compared to plant-based diets.
6
Offers moderate nutrient density with potential for improvement through whole foods and phytonutrient variety.
Overall Health ⓘ
7
Offers moderate benefits for metabolic health and disease prevention but lacks comprehensive long-term evidence across diverse populations.
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 ⓘ
7
Offers moderate flexibility and accessibility but may challenge adherence due to fasting periods and potential social or psychological stress.
7
Offers moderate flexibility and practicality but may challenge adherence due to fasting days and potential psychological stress.
Lifestyle Fit ⓘ
7
Offers moderate flexibility for social and travel scenarios but requires careful scheduling to align with daily routines.
7
Offers moderate flexibility for social and travel scenarios but requires planning for fasting days.
Practicality ⓘ
8
Offers flexible meal timing without requiring specialized foods, equipment, or complex planning, making it broadly accessible and adaptable to most lifestyles.
8
Offers flexibility with minimal cost, accessibility, and preparation effort while allowing normal eating on most days.
Appetite Control ⓘ
7
Moderately effective in reducing hunger through fasting-induced hormonal changes but depends on nutrient balance and individual adherence.
7
Balances satiety through moderate protein and fiber intake but may struggle with hunger management on restricted days without careful food choices.
Fat Quality ⓘ
7
Encourages mindful eating but depends on individual fat choices for optimal quality.
6
Provides moderate emphasis on healthy fats but lacks structured guidance on omega-3 balance and saturated fat sources.
Fiber Intake ⓘ
5
Provides variable fiber intake depending on eating window choices, often lacking sufficient diversity and nutrient density.
6
Provides variable fiber intake depending on non-fasting day choices, but lacks structured fiber optimization.
Gut Health ⓘ
5
Limited support for gut microbiome diversity and digestive tolerance, with mixed evidence on long-term benefits.
5
Limited support for gut microbiome diversity and digestive health due to restricted fiber and lack of prebiotic/fermented food emphasis.
Hormonal Support ⓘ
6
Moderately supports insulin sensitivity and appetite regulation but may disrupt cortisol and sex hormones with improper implementation.
7
Moderately supports hormonal balance with intermittent fasting benefits but may elevate cortisol in some individuals.
Macro Balance ⓘ
6
Allows adaptable macro ratios but lacks inherent structure to ensure balanced intake across diverse dietary needs.
7
Offers flexibility for macro adjustment but lacks structured guidance on optimal ratios for most individuals.
Protein Quality ⓘ
5
Provides adequate protein sufficiency but relies on incomplete plant sources with lower digestibility and amino acid balance.
6
Provides adequate protein on non-fasting days but risks insufficiency on restricted days without deliberate intake management.
Taste ⓘ
6
Offers flexibility for flavorful meals but lacks inherent structure to ensure consistent palatability or variety.
7
Offers moderate variety and adaptability but requires careful meal planning to maintain palatability on restricted days.
Body Composition ⓘ
7
Effectively supports fat loss while preserving lean mass when protein and training are optimized, but risks muscle loss without strict adherence to nutrient intake and resistance exercise.
7
Moderately effective for fat loss with reasonable lean mass preservation when protein intake is adequate.
Energy Balance ⓘ
7
Moderately effective for calorie control but lacks inherent structure to ensure consistent energy balance without external guidance.
6
Provides structured calorie control on fasting days but may struggle with satiety, consistency, and flexibility for varied goals.
Lean Mass ⓘ
6
Moderate effectiveness in preserving lean mass when protein intake and energy availability are adequately managed during fasting periods.
7
Moderately supports lean mass retention when protein intake is adequate and energy balance is maintained.
Athletic Support ⓘ
6
May support athletic performance if calorie and nutrient needs are met, but risks underfueling and impaired recovery without careful planning.
6
May support energy and recovery if well-managed but risks underfueling and nutrient gaps without strict adherence.
Weight Loss ⓘ
7
Promotes moderate calorie deficit and fat loss with reasonable sustainability but risks metabolic adaptation and variable long-term adherence.
7
Promotes moderate calorie deficit with flexible eating patterns but lacks robust evidence for sustained fat loss compared to other structured diets.
