There are those that claim HIIT is less effective than low intensity longer duration cardio. Their reasoning is that most of the calories burned during HIIT come from stored muscle glycogen (carbs) rather than coming from stored adipose tissue. This is true but this is not a bad thing. Research has absolutely proven that it does not make any difference whether stored carbohydrates or stored fats are used as the fuel source. The only thing that matters is how many total calories are burned and more total calories are expended through HIIT as opposed to low intensity low duration cardio.
If you feel like any extra calories you eat go straight to your belly or thighs, you're not imagining things. Those are usually the areas where you store fat because of your genes, hormones, age, lifestyle, and other factors. Your body tends to hoard calories as fat to keep you alive and safe. The challenge is learning how to get rid of that extra fat.
Are you like Old Faithful when it comes to your morning walk or evening jog? Know this: The more you do an activity, the more your body adapts to it, so you burn fewer calories. If you want to light a fire under your metabolism, consider cross-training. For example, if you normally walk, try biking instead. "Since you're not used to working all those different muscles, it's a more intense workout, which can translate into a greater metabolic after-burn because your body is working harder to recover and get oxygen to all your tissues," says Carol Espel, M.S., an exercise physiologist for Equinox Fitness Clubs in New York City.

The sugar contained in fruit is called fructose. Many people have come to believe that fructose is bad for you and will promote fat gain. This is simply not true. Fructose metabolizes differently than other types of sugar but it is still a great choice for carbohydrates. Fructose will restore liver glycogen levels quickly and muscle glycogen stores slowly. Although fructose is technically a sugar it does not cause a spike in blood sugar like many other sugars. This makes fruit and excellent choice for daily consumption.
Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
Many people have come to believe that sugar is one of the main culprits behind weight gain but this is not necessarily true. Sugar will raise insulin levels higher than complex carbohydrates which can be useful particularly around workout time. Raising insulin levels during training will decrease muscle tissue breakdown. For health reasons complex carbs are recommended for other times of the day. Here are some excellent food choices for carbohydrates:
I know for a fact that I am not done here, and as I said before, the overwhelmingly positive support system that is the FWTFL program has me coming back for more. My next comfort zone challenge is spreading the word to other friends, family and anyone that wants to make a change in their health and lifestyle. That is one BIG reason I am signed up for another round. Now that Ive gained the confidence to show the results of my hard work I really want to help in making a difference in others' lives!
2. Go to sleep earlier: A study in BMC Public Health found that people who racked up insufficient sleep on the reg were more likely to have a higher BMI. Meanwhile, researchers from the University of Chicago found that sleep loss causes decreased glucose tolerance and insulin sensitivity (those processes that cause your body to shuttle nutrients into fat cells instead of muscle cells) as well as elevated levels of ghrelin—the hunger hormone—and cortisol, the stress hormone that encourages your body to store fat. What’s more, the less you sleep, the less testosterone your body is able to produce. In short, skimping on sleep messes with all the hormones that help extra fat off your body—so hit the hay already. Shoot for at least 7 hours a night, more if you’re training hard because your body needs more time to repair and rest.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
