Resting metabolic rate means the rate that allows the mere functions that support life itself(1). Every nutrient taken from food, breath breathed, ounce of blood pumped, and cell grown or repaired means energy used in metabolism(2). Digesting and absorbing food (food's thermic effect) and activity are the other expenditures of metabolism. Those who lead sedentary lifestyles have resting metabolic rate account for about 70% of their total energy used in the day. Having more lean body mass (muscle and organs are included) is the biggest determinant of resting metabolism. NOTE: Physical activity is the greatest overall variable in metabolism, taking up anywhere from 15-50% of total metabolic energy expeditures for the day(1)! [We will consider physical activity's effect in a further article.]
Protein is more thermogenic, or takes more energy to process and absorb, than other nutrients in food(1,2) and may even boost metabolism at each meal! NOTE: Pacing protein, taking it in at more evenly during the day versus one primary chunk at dinner, will "support greater muscle retention and muscle growth" and will be even better for metabolism(1)!
A fasting cleansing protocol, more than just a temporary drop to calorie consumption, provides "a 'reset' to appetite, metabolism, and insulin sensitivity" plus causes the body to declutter cells (autophagy) and deal with toxin-loaded fat stores(1). Green tea has "a compound called epigallocatechin gallate" which may provide a little boost to metabolism. Three cups of green tea has about 250 milligrams, enough to burn off an average of a hundred further calories a day(2).
