Three groups of teenagers were studied at the University of Missouri for 3 weeks. They either skipped breakfast, 60% actually do skip, ate a normal amount of protein, a 500-calorie meal consisting of cereal and milk, or a high-protein breakfast.
At the end of each week they filled out a form rating appetite and satiety and their brains were scanned with functional magnetic resonance imaging (fMRI) to measure the activity in the areas that control food motivation and reward-driven eating behavior.
The fMRI results showed those that ate protein for breakfast had decreased brain activity in those areas that controlled food motivation and reward before lunch. Those subjects that ate a high protein breakfast reported an even greater satiety and less appetite.
Skipping breakfast has been strongly associated with snacking high in sugar, fat and calories, overeating (especially at night), weight gain and obesity. Eating a healthy protein-rich breakfast can keep people satisfied longer, control appetite, be less prone to snacking, and prevent overeating.
A small observational study out of Rhode Island showed that weight loss was associated with less frequency and intensity of migraine headaches in obese subjects.
24 severely obese women, who suffered from migraines, were assessed before and 6 months after undergoing bariatric surgery. Their mean body mass index (BMI) before and 6 months after surgery was 46.6 and 34.6, respectively.
Nearly half (46%) of the subjects experienced at least a 50% reduction in their headache frequency, this was despite the fact that nearly 70% of these subjects were still considered obese. This finding was also regardless of the type of weight loss surgery the patient had; 58% of the patients had the LapBand.
Weight loss has yet to be proven to improve migraines, but they think it definitively has an effect.
Their findings were published March 29 in Neurology.
Low testosterone and sexual dysfunction is common in morbidly obese males. A new study out of the University of Louvain in Brussels showed that these problems may be reversed with weight loss after bariatric surgery.
They found low testosterone in 27 out of 75 obese men in an obesity clinic. Signs of androgen, or male hormone, deficiency included low libido and erectile dysfunction were reported in 72% of subjects. They also measured body fat and body mass index (BMI) and found the higher the BMI and body fat the lower the testosterone levels.
Between 2007 and 2010, 17 men underwent bariatric surgery and were assessed 12 months later. They had lost an average of 90.2 pounds. They had no complaints of sexual dysfunction after their weight loss surgery and their testosterone levels had increased to the normal range.
