Study: Wearable Fitness Trackers Result in Weight GAIN!

Not effective for weight loss

Not effective for weight loss

Should you move more to lose weight? Should you even invest in a smart watch that can track how much you exercise – would that help you lose a few more pounds?

It sounds like a reasonable idea. But many studies have questioned how effective exercise really is for weight loss. So how about actually testing if it works?

In a new study, people in a weight-loss program were divided into two groups. One group was the control group. The other group was identical, with one addition: they got to use a wearable fitness tracker. This was to be worn on the wrist to help them track their exercise and hopefully lose more weight.

Unfortunately it did not work… instead it backfired in a spectacular way. Not only did the wearable fitness-tracker group fail to lose extra weight. While wearing it they actually GAINED about 5 additional pounds (2 kg) compared to the control group.

The negative effect of the fitness trackers on body weight was statistically highly significant.

How is this possible? These trackers measure movement and can adjust one’s “allowed caloric intake” accordingly. Thus many people may feel they are allowed to eat more bad foods if they have exercised. This could very well result in weight gain – given that exercise is almost completely useless for weight loss.

These fitness-tracker measurements may become a distraction to what’s really important: what you eat. Getting distracted from the most important thing sets people up to fail.

Are there smarter ways to lose weight? Sure. Eat real low-carb foods, maybe do some intermittent fasting. While you’re doing that, feel free to exercise for health, fitness and wellness reasons – that’s great.

Just don’t believe that exercise will help you lose a significant amount of weight.

Low-Carb Ketogenic Diets for Athletes


4.9 out of 5 stars5 star96%4 star0%3 star0%2 star0%1 star3%28 ratings795 viewsHow can low-carb ketogenic diets help athletes perform better, improve endurance, and prevent bonking?

Such questions used to be considered heretical, but now that more athletes are using ketogenic diets and winning, many people are beginning to sit up and pay attention. Especially since it emerged that the two top finishers of this year’s Tour de France were using some form of low-carb diet.

Possibly the world’s top expert on the topic is Professor Stephen Phinney. In this presentation from the LCHF Convention he shares his decades of expertise.

Former Wimbledon Champion Goes LCHF

1379098-29578311-1600-900

More and more athletes are throwing the old high-carb diet advice in the trash, and beginning to implement LCHF principles instead. One of them being former Wimbledon champion Pat Cash.

Quora: What Was Your Diet Like As a Tennis Player?

Cash was a professional tennis player between 1982 and 1997. After having experimented with both traditional carb loading and the “eat right for your blood type” diet, Cash discovered that an LCHF diet was the best fit for him:

Today I know that a high carbohydrate diet is not the most efficient. I’m now on a diet high in protein and fat with a low or balanced carbohydrate intake.

He even mentions that he uses a stricter version of a low-carb diet – a ketogenic diet. So he’s saying that you don’t need massive amounts of carbs as an athlete? Never would have guessed!

What do you think of Cash’s switch to a low-carb diet?

But exactly what does insulin do in your body? What factors raise and lower insulin? How can you effectively control your insulin?

Dr. Ted Naiman gives you tons of knowledge in this great presentation from the Low-Carb Cruise 2016.
