Energy Saver
Energy-storing type
Gains weight easily even with modest eating. High energy recovery efficiency.
Scientific Background
Possibly FTO gene AA type (risk variant). Tends to have more Firmicutes gut bacteria. Extreme dieting can further increase Firmicutes' energy recovery rate, potentially backfiring.
Practical Advice
Focus on quality over quantity. Increase Bacteroidetes with diverse dietary fiber. Environmental hormones (synthetic surfactants, parabens) also disrupt metabolism, so pay attention to everyday product ingredients.
Mid-Range
Balanced
Normal metabolism. Manages weight through diet and exercise balance.
Scientific Background
Average Firmicutes/Bacteroidetes ratio. Basal metabolic rate within normal range. Blood sugar stability is important for maintaining metabolic efficiency.
Practical Advice
Eat 30+ types of plants per week to boost gut microbiome diversity. Apple cider vinegar (one tablespoon diluted in water before meals) can help suppress blood sugar spikes.
High Efficiency
Energy-burning type
Hard to gain weight, sustained energy.
Scientific Background
Not carrying FTO gene risk variant. Bacteroidetes-dominant gut environment. Efficiently converts both carbohydrates and fats into energy.
Practical Advice
With high metabolism, frequent nutrient replenishment is key. A Mediterranean diet pattern (olive oil, nuts, oily fish, vegetables) protects both metabolism and cardiovascular health.
Ultra High Efficiency
Combustion type
Hard to gain weight even when eating a lot. High energy expenditure.
Scientific Background
Possibly rich in Akkermansia muciniphila. Likely high levels of Christensenellaceae (genetically determined lean bacteria). Lipid-to-ketone body conversion pathway is actively functioning.
Practical Advice
Continue fermented foods and dietary fiber to maintain high metabolism. Intermittent fasting (16 hours) can further activate the lipid metabolism engine.
