FitBits do NOT lead to weight loss

smart wearables

Do not bother investing in an Apple Watch if it is just to lose weight, according to new research.

Tracking your steps, blood pressure and cholesterol might motivate you, and give you an insight into your general wellbeing.

But researchers at the University of Florida found FitBits and other fitness wearables rarely lead to actual weight loss.

In an analysis of six studies on 1,615 people, the team found no users had any meaningful drop in cholesterol or blood pressure, and only one cohort recorded weight loss.

What does eating in moderation really mean? A dietitian explains

You have heard it before (definitely from me!): Go ahead and enjoy your favorite foods - just do so in moderation. It is a phrase meant to help prevent feelings of deprivation when you’re trying to maintain a healthy diet, and while in theory it is sage advice, in reality it is meaningless.

To figure out what moderation means in your day-to-day eating, here’s some help:
I follow a 90/10 approach, which means I make 90% of my food choices healthy, leaving 10% wiggle room for my favorite indulgences (pizza, cookies, ice cream).

By the time you have loaded up on wholesome picks, there is not much room left for the less nutritious stuff (see the handy chart at right for guidance). If you are counting calories, try to limit treat foods to 150 to 200 total calories a day—and do not forget to enjoy yourself!


Sitting for more than nine hours a day raises risk of death...but a brisk 24 minute walk could save you

Previous research has repeatedly suggested that sedentary behaviour is bad and physical activity is good for health.

But a team from the University of Leicester and Norwegian School of Sport Sciences in Oslo wanted to determine how indolent behaviour impacts early death, and analysed eight large studies.

During the 5.8 year follow-up 5.9% of the 36,000 people in the studies had died.

Deaths fell steeply as the total amount of physical activity increased to a plateau of about 300 minutes (five hours) per day of light-intensity physical activity - such as walking - or about 24 minutes per day moderate intensity physical activity, like jogging, tennis or heavy gardening.

However the risk of dying more than doubled for people who spent more than nine and half hours sitting.

Actually, women are not better at multitasking

Multitasking has traditionally been perceived as a woman’s domain.

A woman, particularly one with children, will routinely be juggling a job and running a household – in itself a frantic mix of kids’ lunch boxes, housework, and organising appointments and social arrangements.

But a new study shows women are actually no better at multitasking than men.

The study tested whether women were better at switching between tasks and juggling multiple tasks at the same time. The results showed women’s brains are no more efficient at either of these activities than men’s.
