For adults, WHO defines overweight and obesity as follows :-
• overweight is a BMI greater than or equal to 25; and
• obesity is a BMI greater than or equal to 30.
• Underweight is a BMI less than 18.5.
BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults. However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals.
What causes obesity and overweight?
The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended, however other factors also need to be taken into consideration. Globally, there has been:
an increased intake of energy-dense foods that are high in fat and sugars; and
an increase in physical inactivity due to the increasingly sedentary nature of many forms of work, changing modes of transportation, and increasing urbanization.
However, individual causes may also include:
• Eating disorders especially due to the pattern of binge eating or compulsive eating disorder
• Reduced basal metabolic rate
• Problems related to endocrine glands like adrenals, thyroid, etc
• Conditions like polycystic ovarian syndrome
• Intake of excessive alcohol
• Emotional or physical injury
• Genetic predisposition to overweight
Changes in dietary and physical activity patterns are often the result of environmental and societal changes associated with development and lack of supportive policies in sectors such as health, agriculture, transport, urban planning, environment, food processing, distribution, marketing, and education.
What are common health consequences of overweight and obesity?
Raised BMI is a major risk factor for noncommunicable diseases such as:
• cardiovascular diseases (mainly heart disease and stroke), which were the leading cause of death in 2012
• musculoskeletal disorders (especially osteoarthritis – a highly disabling degenerative disease of the joints)
• some cancers (including endometrial, breast, ovarian, prostate, liver, gallbladder, kidney, and colon)
• Sleeping disorders including insomnia and sleep apnea
• Psychological disorders like chronic depression
• High cholesterol
• Bloating and acid reflux
• Difficulty breathing and asthma
• Skin problems and infection
The risk for these noncommunicable diseases increases, with increases in BMI.
Childhood obesity is associated with a higher chance of obesity, premature death and disability in adulthood. But in addition to increased future risks, obese children experience breathing difficulties, increased risk of fractures, hypertension, early markers of cardiovascular disease, insulin resistance and psychological effects
The Standard American Diet is Even Sadder Than We Thought
(By Forks Over Knives, May 23, 2016)
Although we are one of the most prosperous countries on earth, we die sooner and experience higher rates of disease than other developed nations.
We use the phrase “standard American diet” to describe the stereotypical diet of Americans. But what does the standard American diet actually look like? In the video below, Rip Esselstyn breaks it down for us.
What is the Standard American Diet?
63% of America’s calories come from refined and processed foods (e.g. soft drinks, packaged snacks like potato chips, packaged desserts, etc.)
25% of America’s calories come from animal-based foods
12% of America’s calories come from plant-based foods
Unfortunately, half of the plant-based calories (6%) come from french fries. That means only 6% of America’s calories are coming from health-promoting fruits, vegetables, whole grains, nuts, and seeds.
There’s a good reason we abbreviate to S.A.D! The standard American diet leads to standard American diseases that lead to standard American deaths.
How can overweight and obesity be reduced?
Overweight and obesity, as well as their related noncommunicable diseases, are largely preventable. Supportive environments and communities are fundamental in shaping people’s choices, by making the choice of healthier foods and regular physical activity the easiest choice (the choice that is the most accessible, available and affordable), and therefore preventing overweight and obesity.
At the individual level, people can:
• limit energy intake from total fats and sugars;
• increase consumption of unprocessed fruit and vegetables, as well as legumes, whole grains and nuts; and
• engage in regular physical activity (60 minutes a day for children and 150 minutes spread through the week for adults).
• Address emotional motivators that lead to poor food choices and difficulty regulating quantity and type of food consumed
