New research suggests that H.I.I.T., or high intensity interval training, is just as effective as spending 45 minutes at the gym doing moderate exercise.
This means, specially designed H.I.I.T. exercise routines, or as I like to call them, 1 minute weight loss routines, can be used to replace long, boring cardio work outs at the gym!

Transcript:
Sometimes it seems like everywhere we look we’re exposed to adverts about dieting, urging us to lose weight.
Globally, the diet industry rakes in over £150 billion a year, and that figure is rising fast.
But, at the same time, worldwide obesity levels are also growing, and that matters, because obesity now kills more people than malnutrition.
So, what’s going on? Why are self-control and dieting alone unable to stop the growing obesity epidemic?
Research by physiologists suggests there are important biological factors at play.
Namely, that some of us are simply more genetically predisposed to become obese than others.
The root causes of obesity can be summed up like this: food intake, minus energy burned, equals fat stored.
So, obesity occurs when we consume more than we burn, and fat mass builds up.
But what happens when genetics are thrown into the mix?
Our understanding of this field has been advanced by scientific experiments involving a species of obese mouse.
These mice are always hungry and won’t stop eating. They never feel full.
The mice weigh three times more than normal mice because of a defect in a single gene.
Scientists identified that gene as one that codes for a hormone called leptin.
Leptin is made by fat cells and signals to the brain how much fat mass is in the body.
Without it, the brain mistakenly believes the body is starving, so the mice keep eating, even though they’ve had enough food.
Scientists translated this finding to humans when a four-year-old boy with the same genetic mutation became severely obese.
With regular leptin injections, his over-eating stopped and, by the age of eight, he was no longer overweight.
Studies of twins have helped us to identify the genetic basis of obesity.
Identical twins who come from the same egg and the same DNA have very similar body sizes.
But twins that come from different eggs show much more variability.
These studies show that while single genes are occasionally responsible most obesity cases are caused by a combination of genes working together.
Understanding the causes of obesity is far from simple but genetic factors such as leptin play an important role to regulate food intake and body weight.
So self-control alone is rarely enough to overcome the powerful effect of genes.
That’s why physiologists are working hard to assess how a healthy diet and exercise, combined with a better understanding of how genes influence obesity, can help turn the tide on this global epidemic. Video Rating: / 5

The body mass index, better known as BMI, is a measure of obesity that has been in use for over 200 years. It was a formula created by Belgian mathematician Adolphe Quetelet. It takes your weight (sorry my fellow Americans, everyone else is on the metric system) in kilograms divides and divides it by height in meters squared. And from this you get a number that represent your total body mass relative to your height and weight. The ranges go from underweight to obese, and one decimal point can tip you in either direction. BMI has been used to study obesity in large populations, and for the most part it’s okay for those types of studies. However, when individual health is the topic at hand, using the body mass index can make judging a person’s health a little bit trickier.

Lose Belly Fat | How Vitamin D3 Burns Fat | Weight Loss & Your Thyroid-
Hey, bad news for everyone that’s looking for a magic pill for fat loss. It doesn’t really exist. But, what I’m finding through a lot of research recently is that Vitamin D3 might be as close as we can get to something that can reduce belly fat as anything that’s out there. Let me explain how this works because honestly it’s pretty fascinating.
What Vitamin D is, first and foremost is a fat soluble Vitamin. It’s a fat soluble Vitamin that helps regulate mood, it can help regulate metabolism and most importantly it regulates where calcium goes in the body. But, because it’s fat soluble it means that it’s stored in the fat cell. Start thinking about this: if you have an excess amount of fat or if you’re overweight that means that most of the Vitamin D that you consume, even if you’re taking a supplement, is going to get sequestered into those fat cells and it’s going to stay there meaning you have less bio actively available Vitamin D3 to do the cool things that I’m about to explain.
Let’s talk about how Vitamin D3 actually burns fat. The first method is by increasing something called Leptin. Have you ever eaten food before and gotten full? If you haven’t you’re probably not human. Honestly, what happens is leptin signals your brain that you’re full. When you eat a lot of food you have the production of Leptin, signals your brain that you’re full and you stop eating. Problem is that without Vitamin D3, Leptin levels don’t generally increase that much. If you have enough D3 your brain can signal and your brain can be told you need to stop eating. It’s that simple. Low levels of Vitamin D3 those Leptin levels don’t get too high and you can keep eating, making it very easy to overeat.
Remember what I said about the Vitamin D3 getting stored in fat cells? Think about this, if you already are low in D3 and then you eat and you don’t have enough Leptin so you keep eating more then you’re going to develop more fat cells, which means you’re going to hold onto more Vitamin D in the fat cells and more and more to the point where you have this snowball effect where you continue to store fat. Are you one of those people that have just looked in the mirror and say how did this happen to me?
Honestly, I was one of those people seven or eight years ago. The other way that Vitamin D3 is proving to potentially be a good belly fat burner is through the modulation of the parathyroid and calcitriol hormones. The Parathyroid is a small set of glands around the thyroid in our throat and basically when they produce parathyroid or they produce calcitriol, we have a rapid increase in how our body stores fat. It tends to want to store it more. If we have enough Vitamin D3 the parathyroid and calcitriol hormones aren’t quite as crazy. They’re not going quite as haywire, which means your body slowly stores and slowly metabolizes fat versus doing it rapidly, making it where you look in the mirror and feel like it happened overnight.
Those are the two main reasons that Vitamin D3 is starting to play a big role in belly fat. This wouldn’t be a traditional video of mine if I didn’t at least reference one peer reviewed, double blind placebo study. One study took 218 women. These 218 women they gave a strict diet and exercise program to and they asked them to follow it for a year. Then they took half of these women and they gave them Vitamin D. The other half of the women they gave a placebo. After one year of time, it was found that the women that took the Vitamin D had on average seven pounds more weight loss than those that didn’t take the Vitamin D. It doesn’t sound like much but just by adding Vitamin D, it’s pretty dang interesting.
Then, there’s one other study. There is another study that found that those that were taking Vitamin D3 had a better waist to hip ration than those that were not.
