The BMI is a measure of your weight in relation to your height, and your waist circumference measures your abdominal fat. Combining these with information about your additional risk factors will give you an idea of your risk for developing obesity-associated diseases.
The medication is approved for patients who are obese (BMI >30) or overweight (BMQ >27) with one weight-related health issue. The predominant side effects were headache and dizziness, as well as fatigue. In patients with diabetes, low blood sugar was also a concern when taking Belviq.
Measuring waist circumference helps screen for possible health risks that come with overweight and obesity. If most of your fat is around your waist rather than at your hips, you’re at a higher risk for heart disease and type 2 diabetes. This risk goes up with a waist size that is greater than 35 inches for women or greater than 40 inches for men. To correctly measure your waist, stand and place a tape measure around your middle, just above your hipbones. Measure your waist just after you breathe out.
Fortunately, there are lots of weight-loss options available for boomers, and all the good ones revolve around an age-old formula for shedding pounds: eating less and exercising more. That’s something any generation can get behind.
Gout is a disease that affects the joints that is caused by high levels of a substance called uric acid in the blood. The large amount of uric acid can form into solid or crystal-like masses that deposit in the joints. Gout is more common in overweight people and the risk of developing the disorder increases with higher body weights.
Although cyproheptadine has been studied in patients with cancer and cachexia,38 routine use in older adults with unintentional weight loss has not been studied. Dronabinol (Marinol) and human growth hormone have been studied in small, limited trials with mixed results for short-term, small weight gains. Dronabinol has been associated with significant adverse effects, particularly central nervous system toxicity. Human growth hormone has been associated with increased mortality.17
Some wholesome foodies openly celebrate fat and problem carbs, insisting that the lack of processing magically renders them healthy. In singing the praises of clotted cream and lard-loaded cookies, for instance, a recent Wall Street Journal article by Ron Rosenbaum explained that “eating basic, earthy, fatty foods isn’t just a supreme experience of the senses—it can actually be good for you,” and that it’s “too easy to conflate eating fatty food with eating industrial, oil-fried junk food.” That’s right, we wouldn’t want to make the same mistake that all the cells in our bodies make. Pollan himself makes it clear in his writing that he has little problem with fat—as long as it’s not in food “your great-grandmother wouldn’t recognize.”
Neuroscientist James Fallon discovered through his work that he has the brain of a psychopath, and subsequently learned a lot about the role of genes in personality and how his brain affects his life.

An initial step in detecting liver damage is a simple blood test to determine the presence of certain liver enzymes in the blood. Under normal circumstances, these enzymes reside within the cells of the liver. But when the liver is injured, these enzymes are spilled into the blood stream, and can lead to diseases like fatty liver, type 2 diabetes, obesity, and hepatitis. Several medications also can increase liver enzyme test results.
In the second paper, all CVD risk factors significantly improved in the diet and exercise group (Villareal 2006b). Specific mechanisms were not proposed, but the discussion focused on medical care costs related to metabolic coronary heart disease (CHD) risk factors that were ameliorated by the intervention (Table 1). In the third paper (Villareal 2008), bone turnover was measured by type 1 collagen C-terminal telopeptide (CTX), osteocalcin, and bone-specific alkaline phosphatase. There was a marked increase in serum CTX (~100-fold) and osteocalcin (~60-fold) concentrations in response to weight loss indicating that bone resorption and formation, respectively, were stimulated. Moreover, the increases in both CTX and osteocalcin concentrations correlated with decreases in hip bone mineral density (BMD), suggesting that weight-loss induced bone loss was due to increased bone turnover, with greater stimulation of bone resorption than bone formation. However, the clinical significance of the decrease in BMD was not clear as all participants had high baseline BMD Z-scores, and none had evidence of osteoporosis following weight loss. The investigators argued that BMD was not lost in the spine, which implies that the exercises were more effective in preserving BMD at this site. Exact mechanisms for loss of BMD with weight loss are not currently elucidated, but it was suggested that weight loss decreases the mechanical stress on the hip, without negatively impacting the spine or wrist. Weight loss was also associated with a 25% reduction in serum leptin that was highly correlated with decreased hip BMD. No such relationship was found between decreasing estradiol and changes in BMD. Leptin was discussed in the context of its inhibiting action on the expression of receptor activator of nuclear factor κB (NF-κB) ligand levels (Burguera 2001) and osteoblast differentiation (Cornish 2002). Levels of insulin-like growth factor 1 (IGF-1), cortisol, and parathyroid hormone (PTH) did not change in response to loss, which suggests that these bone-active hormones were not involved with the loss of BMD in the hip. Vitamin D supplementation during the trial did not reach optimal serum concentrations and whether higher dose Vitamin D supplementation could have slowed bone loss, was raised by the investigators. It was also noted that bone quality was not measured and could have been positively impacted by the exercise training intervention.
…high-calorie, processed food is less expensive and quicker to prepare than fresh fruits and vegetables. Poverty and lower levels of education have also been linked to obesity (NIH, 2006). It has been suggested that one reason why poverty and lower educational levels are risk factors for obesity is that high-calorie, processed food is less expensive and quicker to prepare than fresh fruits and vegetables (NIH, 2006). Through observation and the anecdotes patients have shared with me, I have come to believe the social environment indeed contributes to the increasing prevalence of obesity. To date, only a few research studies have focused on this factor.
Treatment should focus on the underlying cause. This often involves a multidisciplinary team, including dentists; dietitians; speech, occupational, or physical therapists; and social service workers. Common strategies to address unintentional weight loss in older adults are dietary changes, environmental modifications, nutritional supplements, flavor enhancers, and appetite stimulants.27
Your doctor may diagnose overweight and obesity based on your medical history, physical exams that confirm you have a high body mass index (BMI) and possibly a high waist circumference, and tests to rule out other medical conditions.
Documenting such differences does not mean the discrepancies are responsible for obesity, however. To demonstrate cause and effect, Gordon and his colleagues conducted an elegant series of experiments with so-called humanized mice, published last September in Science. First, they raised genetically identical baby rodents in a germ-free environment so that their bodies would be free of any bacteria. Then they populated their guts with intestinal microbes collected from obese women and their lean twin sisters (three pairs of fraternal female twins and one set of identical twins were used in the studies). The mice ate the same diet in equal amounts, yet the animals that received bacteria from an obese twin grew heavier and had more body fat than mice with microbes from a thin twin. As expected, the fat mice also had a less diverse community of microbes in the gut.
A full thyroid panel is needed to identify hypothyroidism in dogs. Your vet will put your dog on thyroid supplementation and ask you to bring him in for periodic re-testing. If all goes well, he should slim down and get back some of his energy, keeping in mind that senior dogs aren’t as active as when they were younger.
Diabetes: Type 2 diabetes was once called adult-onset diabetes. Now with the rise in childhood obesity, there is a dramatic rise in the number of children suffering from type 2 diabetes. Untreated, this can be a life-threatening condition.
At last, it’s time to toss that scale that’s collecting dust under your bathroom vanity. “At advanced ages, you cannot afford to lose muscle, organ tissue, or bone mass,” says Huizenga, “which means focusing on the number on the scale is especially inappropriate.” Instead, invest in a body fat measurement tool (such as calipers or an electrical impedance device) or simply just measure your waist size. The general rule of thumb is that your waist size should be no more than half your height. So, a woman who’s 5′ 4″ (or 64 inches) should have a waist size no larger than 32 inches; a man who’s 5′ 9″ (or 69 inches) should have a waist no larger than 34.5 inches.
