But in combination with a high-calorie diet
, the insulin levels were 10 times higher in stressed mice.
"Our findings revealed a vicious cycle, where chronic, high insulin levels driven by stress and a high-calorie diet
promoted more and more eating," explains Professor Herzog.

The scientists took samples from the participants at four points during the study: at baseline; when their weight peaked following the high-calorie diet
; when their weight returned to baseline; and then following 3 months of stability after their weight returned to baseline.
Researchers at Chang Gung University in Taiwan fed groups of middle-aged and young rats a very high-calorie diet
, then compared them to a control group fed a normal diet.
For instance, a chapter on the nervous system contains the subheading "The Aging Brainstem and Hearing." In this section, Merrill explains the relationship between a high-calorie diet
and age-related hearing loss.
The principle causes of the problem have been identified as sedentary lifestyle and high-fat, high-calorie diet
. But it is far more than calories in/calories out.
When exposed to a high-fat, high-calorie diet
in a laboratory, they develop marked obesity and many of the hallmarks of metabolic syndrome, including insulin resistance (IR) [15, 17-20], dyslipidemia [18, 20, 21], and hypertension [18, 20].
Building muscle requires regular weight-resistance workouts, cross training, nutritional supplements and a high-calorie diet
. But with Daez's daily schedule, he finds it challenging to strike a balance.
Working with about 100 types of mice, Aldons Lusis of UCLA and colleagues found that most strains gained weight when fed a high-fat, high-sucrose diet, but stopped gaining weight after a few weeks on the high-calorie diet
. Only a few strains continued to pack on body fat over the course of the eight-week experiment.
Suggestion: If you eat a high-calorie diet
, cut down on your calorie intake and eat foods that make up a healthy diet, such as fruits, vegetables, lean meat, fish, whole grains and low-fat dairy products.
We might speculate that because women generally are more sensitive to reward (Appetite 2005;45:198-201), exposure to high-calorie diet
options available in the United States might have a stronger effect on them than on men.
