The thrifty gene hypothesis postulates that, due to dietary scarcity during human evolution, people are prone to obesity. Their ability to take advantage of rare periods of abundance by storing energy as fat would be advantageous during times of varying food availability, and individuals with greater adipose reserves would be more likely to survive famine. This tendency to store fat, however, would be maladaptive in societies with stable food supplies.[126] This theory has received various criticisms, and other evolutionarily-based theories such as the drifty gene hypothesis and the thrifty phenotype hypothesis have also been proposed.[127][128]
The researchers who conducted the earlier CDC study suggested that public health efforts and aggressive treatments aimed at preventing chronic diseases had greatly reduced the obesityobesity-related death risk.
Following a sensible diet can help prevent excess weight gain. But it’s also important to note that older adults occasionally have naturally occurring loss of taste or difficulty chewing that can make adhering to certain dietary recommendations challenging.
Though sometimes downplayed or even ignored by elderly patients, sudden weight loss is a serious cause for concern says Dr. Barry Fabius, medical director of geriatrics at Holy Redeemer Health System in Philadelphia, Pennsylvania. “My radar goes up,” says Fabius. “I immediately wonder if I’m dealing with cancer.”

Order blood tests to screen for complications. A lipid panel test can check if you have high cholesterol or triglyceride levels in your blood. A liver function test can determine if your liver is working properly. A fasting glucose test can find out if you have prediabetes or diabetes.

There are many options for weight loss and as you’ll discover, not every option is appropriate for every patient. The journey to weight loss is different for everyone based on your individual lifestyle and goals.
The best diet for seniors is not always the diet program that is most popular or that is recommended for dieters in other age groups. It’s important for seniors to maintain muscle mass, to find an eating plan that provides proper nutrition, and that does not interfere with medications or the management of your medical conditions.
Individuals with conditions or lifestyle factors that increase their risk of developing coronary heart disease, such as high blood pressure, diabetes, cigarette smoking, high blood cholesterol, or having family members with early onset heart attacks and coronary heart disease
Every time your heart beats, it pumps blood through your arteries to the rest of your body. Blood pressure is how hard your blood pushes against the walls of your arteries. High blood pressure (hypertension) usually has no symptoms, but it may cause serious problems, such as heart disease, stroke, and kidney failure.
The U.S. Food and Drug Administration approved orlistat capsules, branded as alli, as an over-the-counter (OTC) treatment for overweight adults in February 2007. The drug had previously been approved in 1999 as a prescription weight loss aid, whose brand name is Xenical. The OTC preparation has a lower dosage than prescription Xenical.
The definition of obesity varies depending on what one reads. In general, overweight and obesity indicate a weight greater than what is considered healthy. Obesity is a chronic condition defined by an excess amount of body fat. A certain amount of body fat is necessary for storing energy, heat insulation, shock absorption, and other functions.
To lose weight, seniors should implement a nutritious diet that include more fruits and vegetables. Consuming calcium, vitamins, protein rich foods like whole grains, whole wheat, cereals, lentils and eggs release the energy required for any physical activity. Senior weight loss is possible and can be achieved with a nutritious diet and regular work out.
Losing weight is difficult, and interventions that work in younger adults cannot be assumed to translate to older populations with co-morbidities, low muscle mass and frailty (Villareal The appropriate treatment approach for obesity remains highly contentious due to the lack of evidenced-based data demonstrating that long-term weight loss is net beneficial or harmful in this age group. There is evidence that successful weight loss is possible in adults 65 years and older (Villareal 2006a; Villareal 2006b; Villareal 2008; Frimel 2008; Lambert 2008; Shah 2009; Villareal 2011a; Armamento-Villareal 2012; Shah 2011; Kelly 2011). However, weight-loss trials have reported losses of lean body mass and bone mineral density, in addition to fat mass (Villareal 2006a; Villareal 2006b; Villareal 2008; Frimel 2008; Lambert 2008; Shah 2009; Villareal 2011a; Armamento-Villareal 2012; Shah 2011; Kelly 2011; Bales 2008). These negative outcomes discourage many geriatricians from advising weight loss to their obese older patients (Heiat 2001; Rossner 2001; Sorensen 2003; Villareal 2005; Zamboni 2005; Rolland 2006; Morley 2010), despite improvements in body composition, physical function, metabolic and cardiovascular parameters that accompany weight loss (Forsythe 2008; Anandacoomarasamy 2009; Cheung 2012; Erteck 2012). Given these positive functional and metabolic outcomes, it is somewhat surprising that advising weight loss in obese older adults is still shunned in the medical community (Houston 2009; Sommers 2011). Compounding the confusion surrounding risks versus benefits from intentional weight loss is the lack of human studies to elucidate the mechanisms associated with the loss of muscle and bone. Also lacking are trials with adequate follow-up to assess the behaviors associated with long-term maintenance of weight loss and health outcomes related to sustained weight loss.
