How does gender affect metabolic rate?

Women do tend to have slower metabolisms than men, but the difference is primarily a function of muscle mass and body size, not gender. We might expect someone with more muscle and less fat to be more metabolically healthy.

How does the gender affect the basal metabolic rate?

Gender is also a significant determinant of BMR, with men having a greater BMR than females after adjustment for body composition (9,10). In addition, BMR markedly decreases with advancing age in sedentary populations (11) at a rate of ∼1–2% per decade after the age of 20 (ref.

Who has a higher metabolic rate male or female?

Men tend to have a higher metabolism than women, but genes, body size, and age all play a role in how the body gains fat and loses muscle.

Why do males typically have a higher basal metabolic rate than females?

Why do males typically have a higher basal metabolic rate than females? Because males naturally have lower % of body fat and higher muscle mass.

How does gender affect drug metabolism?

Physiologic differences between men and women affect drug activity, including pharmacokinetics and pharmacodynamics. Pharmacokinetics in women is affected by lower body weight, slower gastrointestinal motility, less intestinal enzymatic activity, and slower glomerular filtration rate.

What factors affect metabolic rate?

Your metabolic rate is influenced by many factors – including age, gender, muscle-to-fat ratio, amount of physical activity and hormone function.

Does gender affect weight?

Gender influences the association of HRQoL and weight status, with females with excess weight having lower HRQoL [7, 12, 21]. A relationship has also been observed between HRQoL and weight status as children and adolescents age with younger overweight adolescents reporting significantly lower HRQoL scores [12].

How does gender affect energy expenditure?

Women have a higher proportion of body fat compared to men. However, women consume fewer kilojoules per kilogram lean mass and burn fat more preferentially during exercise compared with men. During gestation, women store even greater amounts of fat that cannot be solely attributed to increased energy intake.

Why do guys have higher metabolism?

First, there is the matter of muscles and metabolism. Men tend to have more muscle than women, and because muscle burns more calories than fat, men tend to have a faster metabolism, too — anywhere between 3 to 10 percent higher than women, studies have shown.

What is the main explanation for the difference in basal metabolic rate between males and females of the same body weight?

The main explanation for the difference in basal metabolic rates between males and females of the same body weight and the reason that males have a higher metabolic rate, is that males have a higher percentage of lean body mass (muscle) than females.

Do males always have a greater BMR than females?

Males have a greater BMR per unit of body weight because of body composition differences, including more lean body mass, which requires more calories to maintain. Males always have a greater BMR than females. … A bomb calorimeter is used to calculate the number of calories in foods.

Why males and females respond differently to drugs or toxins?

Both parameters are dependent on body weight for most drugs independent of sex differences. Females have a higher percent body fat than males which can affect the Vd of certain drugs. Renal clearance of unchanged drug is decreased in females due to a lower glomerular filtration.

How does gender affect bioavailability?

On average, men are larger than women. … Total drug absorption does not appear to be significantly affected by sex although absorption rates may be slightly slower in women. Bioavailability after oral drug dosing, for CYP3A substrates in particular, may be somewhat higher in women compared to men.

How does maternal body mass affect drug metabolism?

Expanded extracellular volume and total body water will increase volume of distribution for hydrophilic drugs, leading to lower plasma concentrations. In addition, maternal body fat expands by approximately 4 kg, increasing the volume of distribution for lipophilic drugs.
