Healthy eating, physical activity, optimal sleep, and stress reduction are important to achieving optimal health and managing
The individual has no control over some of these factors, including developmental determinants, genetic makeup, gender, and age. Other factors that influence body weight over which the individual has potential control include level of physical activity, diet, and some environmental and social factors.
Although healthy weight guidelines have been developed at population levels, each person's healthy weight range will vary and depend on factors such as age, sex, genetics, body frame, existing medical history, lifestyle habits, and weight as a young adult.
You gain weight when you take in more calories (through food and drinks) than you use up from physical activity and daily living. But there are many different factors that can affect weight gain, such as: The world around you. Your home, community, and workplace all may affect how you make daily lifestyle choices.
As we age, metabolism — how the body gets energy from food — can change. This means that some older adults must become more active or eat fewer calories to maintain or achieve their ideal weight. Other older adults may lose weight unintentionally.
A healthy weight for adults is generally a body mass index (BMI) between 18.5 and 24.9. The online BMI calculator will help you measure your BMI.
Demographic information, including sex/gender, age, and race/ethnicity are all important factors. The disease state of patients could also factor into the formulas used in identifying ideal needs.
The weight of an object depends primarily on two factors: mass and gravity.
Food and Activity
People gain weight when they eat more calories than they burn through activity. This imbalance is the greatest contributor to weight gain.
Many factors influence these changes, including hormonal, environmental, and disease processes. Growth is associated with increases in fat-free mass and fat mass, and changes in the relative proportions of these body components, which have important implications for accurate measurement of body composition.
BMI is a calculated measure of body weight relative to height. For adults, BMI categories are underweight, healthy weight, overweight, and obesity.
Genetics: About 50% of fat distribution is determined by genetics. Therefore, it's likely that our weight will cluster in similar places as close relatives. Gender: Women usually have higher amounts of body fat than men and are more likely to accumulate fat in the hips and buttocks.
In everyday life, the idea of optimum weight refers to the weight someone should be, on average, based on their height, sex, bone structure, body type and the size of their muscles.
People who regularly eat and drink more calories than they burn each day are more likely to gain extra weight, including belly fat. Getting older also makes a difference. People lose muscle as they age. And the problem is worse for those who are not physically active.
If you're asking yourself, “Why am I gaining weight when I barely eat,” several factors may be at play. Your body may be holding onto fat stores if your eating habits are inconsistent or restricted. Or, your weight gain may be the effect of a sedentary lifestyle, medical condition, or long-term stress.
Diet and lifestyle factors contribute to development of obesity and overweight. Some of the most common ones are: eating large amounts of processed or fast food – this is food that's high in fat and sugar. drinking too much alcohol – alcohol contains a lot of calories.
