To achieve a healthy weight and adopt healthier eating habits, people may need to see several health professionals, including a dietitian, behavioral therapist, exercise physiologist and obesity expert, according to the Mayo Clinic.
Working with a diverse team of health experts can help people make long-term changes in their eating and exercise habits and develop strategies to address any emotional and behavioral issues that may lead to weight gain and unhealthy lifestyle habits.
Obesity may also be linked to the company a person keeps: It has been found to "spread" socially among friends.
A 2011 study published in the American Journal of Public Health suggested that the reason for this social spread was because friends share similar environments and carry out activities together that may contribute to weight gain.
But others argue that calling obesity a disease automatically categorizes a large portion of Americans as "sick," when they may not be.
Instead, critics say obesity should be considered a risk factor for many diseases, but not a disease in and of itself.Complications are either directly caused by obesity or indirectly related through mechanisms sharing a common cause such as a poor diet or a sedentary lifestyle.The strength of the link between obesity and specific conditions varies.These benefits include improvements in blood pressure, cholesterol levels and blood sugars.According to the CDC, here are some tips that may help people lose weight successfully: Once you've lost weight, regular physical activity (60 to 90 minutes of moderate-intensity physical activity per day, on most days of the week) can help keep weight off, the CDC says.Behavior changes, such as understanding what stresses or situations may contribute to overeating and learning to modify these behaviors, are also important for achieving weight-loss goals.Even small amounts of weight loss — such as 5 to 10 percent of your total body weight — can have health benefits, the CDC says.Although there are lots of fad diets, such short-term dietary changes are not the best way to keep weight off permanently, the CDC says.Instead, people should aim to make long-term changes, such as eating healthy on a regular basis, and boosting daily physical activity.People with a BMI of 30 or more are eligible for an adjustable gastric band (one type of bariatric surgery) if they also have at least one serious health problem linked with obesity.Other treatment options for obesity include certain prescription and over-the-counter medications that curb appetite, such as orlistat and lorcaserin, but can cause side effects, such as cramping, diarrhea, headaches, dizziness and nausea, according to the Mayo Clinic.
