A Facebook executive says fasting for 15 hours a day changed his life

Dan Zigmond lost over 20 pounds in less than a year through intermittent fasting

In 2014, Dan Zigmond, director of analytics at Facebook, lost more than 20 pounds in less than a year. He didn’t track steps or count calories. Instead, Zigmond gave up eating for 15 hours a day.

“I don’t think about it as ‘fasting,’ per se. There’s a period of time where I eat, and there’s a period of time when I don’t,” Zigmond told Business Insider. “Life is all about balance.”

Bullies and their victims obsessed with weight-loss

School bullies and their victims are more obsessed with weight-loss than anyone else, according to new research by the University of Warwick.

Professor Dieter Wolke and Dr Kirsty Lee, in the Department of Psychology, discovered that teenagers who are involved in bullying in any way — from bullies, to their victims, to those who both bully and get bullied — are more likely to develop concerns about their eating and exercise behaviours, and become preoccupied with losing weight.

Almost 2800 adolescents in UK secondary schools were screened for involvement in bullying, through self and peer assessment.

A sample of those involved in bullying – around 800 teenagers — was analysed for eating and exercise thoughts and behaviours, self-esteem levels, body image and emotional wellbeing.

They were asked to complete established questionnaires — such as Rosenberg’s Self-Esteem Scale, the Strengths and Difficulties Questionnaire, the Body Esteem Scale for Adolescents and Adults, and the eating behaviours component of the Child and Adolescent Psychiatric Assessment.

Results from these tests showed that 42% of bullies have extreme preoccupation with weight-loss, as well as 55% of bullying victims, and 57% of teens who both bully and are bullied. This is compared with adolescents who have no involvement with bullying – 35% of those are obsessed with losing weight.

The researchers say that bullies are preoccupied with weight-loss because they are driven by the desire to be the most attractive, strongest and fittest.

Victims of bullying suffer from reduced psychological functioning due to being picked on — causing weight-loss obsession, chronically low self-esteem levels, and eating disorders.

Teenagers who are bullied, and also bully their peers — bully-victims — have the highest pre-occupation with weight-loss and are most likely to develop eating disorders, as well as other psychological problems.

Bully-victims are doubly affected, by both the desire to be attractive, strong and popular, and the psychological harm and lowered levels of self-esteem which come from peer victimisation.

From the results of this research, Professor Wolke argues that clinicians dealing with victims of peer bullying should directly target their emotional wellbeing, and issues with self-esteem and body image.

Professor Wolke comments:

“Bullies are bi-strategic — they want to be popular by being dominant though bullying but also want to look good”.

“In contrast those who are bullied, the victims, are occupied with weight because they have poor body and self-esteem and are emotionally stressed and hope that looking good might make them feel better.

“If we could reduce bullying, it would help to improve self-worth, body image, wellbeing and healthy ways of keeping fit.”

The research, ‘Does psychological functioning mediate the relationship between bullying involvement and weight loss preoccupation in adolescents? A two-stage cross-sectional study’, is published in the International Journal of Behavioral Nutrition and Physical Activity.

¿Qué Es Más Eficaz para Bajar de Peso, Comer Bien o Hacer Ejercicio?


Por el Dr. Mercola

Entonces, necesita perder unas cuantas libras. La pregunta es ¿cómo lograrlo? Si es como la mayoría de las personas, probablemente piensa que debe comprometerse a ir al gimnasio más seguido. Sin embargo, esta idea podría ser lo que le está  impidiendo tener éxito.

Cuando se trata de bajar de peso – y mantenerlo – es sumamente importante entender que todo depende de su boca. Su alimentación es mucho más importante que el ejercicio,1 aunque el movimiento físico realmente lo ayuda realmente a optimizar su salud y estado físico.

El ejercicio ha demostrado ser tan eficaz (o más) que muchos terapias a base de medicamentos para  tratar los problemas de salud comunes como la diabetes, las enfermedades cardíacas y la depresión, por mencionar algunas.

Así que, el ejercicio definitivamente desempeña un papel muy importante en la salud óptima–pero simplemente no es la clave para bajar de peso.

No puede llevar una alimentación a base de comida chatarra y pensar que por el simple hecho de hacer ejercicio bajará de peso. Además, la hora y la cantidad de comida que consume también pueden influir en todo esto.

Comer menos y programar sus comidas puede ser particularmente útil para llevar su metabolismo en la dirección correcta.

This Is The Best Exercise To Lose Your Belly, Says Science

belly fat exercises
In the weight loss game, not all fat is created equal. And if you’re trying to lose that belly you just know is hiding a six-pack, stomach fat is a particularly stubborn beast.
But never fear: A recent study just found that one workout is particularly adept at burning off belly—aka visceral—fat.

Visceral fat is not only a pain in the butt, it’s also extra unhealthy, since it’s located in the abdominal cavity and surrounds several important organs. So researchers looked into how certain types of training could slim this particular area. (Got 10 minutes? Then you’ve got time to lose the weight for good with Prevention’s new 10-minute workouts and 10-minute meals. Get Fit in 10: Slim and Strong for Life now!)

In the study, which was published in the Journal of Sports Medicine and Physical Fitness, participants did four workouts a week, doing various types of exercise. One group did four steady-state cardio and strength workouts, while another group did two steady-state workouts and two high-intensity interval training (HIIT) workouts.

Turns out HIIT is queen: The HIIT group not only lost more weight overall, they also lost more inches from their waistline, showing a significant reduction in visceral fat, compared with the group that stuck to the steady-state gym routine. As a bonus, the HIIT group saw an increase in cardio-respiratory fitness, while the other group did not.

The researchers say the fact that HIIT workouts are short and intense—allowing you to push your bod to the limit—may be why HIIT does such a killer job at incinerating the most unshakable fat.

So, ready to HIIT it hard? Start with this 5-move HIIT workout. That six-pack will reveal itself before you know it.

Water intake overlooked in obese people, study shows

Water intake overlooked in obese people

Researchers are learning whether a simple part of our diets might be linked to a healthier weight — and it has nothing to do with carbs, fat or protein.

The potential secret weapon? Water.

People who are obese and have a higher body mass index (BMI) are more likely to be inadequately hydrated and vice versa, suggests recent research from the University of Michigan published in Annals of Family Medicine.
