Basically, carbohydrates are the primary source of energy production in body tissues. When the body is deprived of carbohydrates due to reducing intake to less than 50g per day, insulin secretion is significantly reduced and the body enters a catabolic state. Glycogen stores deplete, forcing the body to go through certain metabolic changes. Two metabolic processes come into action when there is low carbohydrate availability in body tissues: gluconeogenesis and ketogenesis.[4][5]

Never met Kristen McGee in person, but hope to join one of her classes next time I'm in NYC as this is my ultimate Pilates DVD. I'm 35 years old, married, no kids, busy work-schedule and this DVD simply keeps me in shape. I like her attitude, which is not obnoxious as some trainers tend to be... I can relate to her and her instructions are always very clear.


If you live in a challenging climate (e.g. almost anywhere in Canada!), remember that you do not have to cycle outdoors to lose weight. In the winter, spin classes could work really well for you, especially if you value having someone else to encourage and guide you. Although bear in mind that these can be quite fast-paced, so they will be a bit much for a beginner. I actually tried one back in the day when I was just starting out in cycling, and had to leave the class, red-faced and exhausted, half-way through. I was too embarrassed to ever go back – which, in retrospect, was stupid of me. Everyone has to start somewhere!
If you haven't used your gym's rowing machine, you're missing out on one of the best pieces of cardio and strength equipment. Working your quads, glutes, hamstrings, core, arms, and back, you get a total-body workout that'll have you pouring sweat. Contrary to what most people think, the power of rowing mostly comes from your legs—not your arms. Engaging your quads and glutes, you drive your legs back to pull the handle towards your chest. Follow these pro tips to perfect your rowing form.
Doing intervals is an excellent way to keep your metabolism up long after you finish your exercise. Interval training is when you start out at a slow speed for one to two minutes, then go faster for one to two minutes. Continue to do this routine until you are finished and then do a five minute cool down lap. If you are unable to do the faster pace for a whole minute, just increase the speed for 20-30 seconds and then slow down letting your heart rate come down. Then repeat the intervals.
Insulin is a hormone that lets your body use or store sugar as fuel. Ketogenic diets make you burn through this fuel quickly, so you don’t need to store it. This means your body needs -- and makes -- less insulin. Those lower levels may help protect you against some kinds of cancer or even slow the growth of cancer cells. More research is needed on this, though.
Olivier Poirier-Leroy is a former national level swimmer and the author of the books YourSwimBook and Conquer the Pool. He writes all things high-performance swimming, and his articles were read over 3 million times last year. His work has appeared on USA Swimming, SwimSwam, STACK, NBC Universal, and more. He's also kinda tall and can be found on Twitter.

A ketogenic diet helps control blood sugar levels. It is excellent for managing type 2 diabetes, sometimes even leading to complete reversal of the disease. This has been proven in studies. It makes perfect sense since keto lowers blood-sugar levels, reduces the need of medications and reduces the potentially negative impact of high insulin levels.


Seems like a lot, right? Wrong. These workouts were challenging, but really simple to do. Since the workouts were only 30 minutes long, and the app tells you exactly what to do, I never got bored doing the workouts. It felt good to go really hard and push myself, and by the end of the 30 mins I was usually exhausted! It’s amazing to see yourself drop time and swim faster every single week.

Spinning, whether it's on an actual bike or a stationary one, is one of the best ways to burn calories and build endurance. If you don't like running, spinning is a low-impact alternative that'll crank up your heart rate. But there's more to pushing the pedal than speed. By practicing good form and engaging your core as well as your thighs and glutes, spinning can be a full-body workout, too. Whether you're doing a heavy climb in first position or sprinting in second, your core is the key to spinning efficiently and quickly. And as you drive your foot down with each stroke, it's all about squeezing your inner thighs.


The ketogenic diet is a mainstream dietary therapy that was developed to reproduce the success and remove the limitations of the non-mainstream use of fasting to treat epilepsy.[Note 2] Although popular in the 1920s and '30s, it was largely abandoned in favour of new anticonvulsant drugs.[1] Most individuals with epilepsy can successfully control their seizures with medication. However, 20–30% fail to achieve such control despite trying a number of different drugs.[9] For this group, and for children in particular, the diet has once again found a role in epilepsy management.[1][10]

On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids.[57] Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.[56]
This workout plan is between 4 and 12 weeks long, depending on how much weight you want to lose. Follow this workout plan and practice healthy eating and portion control, which means eating the right food in the right quantities at the right times, and you’ll be able to burn off at least a pound or two of body fat each week. But remember, you’ll also be doing resistance training to gain muscle in all the right places, so you’ll want to keep track of your progress with body measurements and, if you can, body fat percentage.

"Depending on your approach, [keto diets] can contribute to significant lean body mass loss along with fat loss," said Melinda Manore, a professor of nutrition at Oregon State University. (Typically, dieters want to shed only fat, not lean body mass, which includes muscle.) And as with other fad diets, people typically regain the weight once they go off the diet.
Most gyms have stationary bikes, but the best ones for revving up weight loss are often found in the group exercise studio – whether you ride them as part of a class or cycle solo. “Indoor bikes for group cycling tend to fit a rider differently than a stationary bike,” says Krista Popowych, a Vancouver, B.C.-based fitness expert and Master Trainer for Keiser, a company that creates exercise equipment, including bikes and education for group cycling.
Chickpeas are naturally high in carbs — a single cup contains 45 grams of carbohydrates.31 However, you can modify the recipe to make it more nutritious. Try this recipe from Pete Evans, which replaces the chickpeas with beetroot.32 Beware, though, that beets have the highest sugar content of all vegetables, so consume them in very controlled amounts.

Lie on your stomach with your forehead down, your pubis anchored to the mat, and your inner thighs pressed tightly together. Your arms should be stretched forward with your palms down, and your feet should be pointed. Lift your arms, legs, chest, and head up on one count, and hold (A). Inhale and exhale normally as you alternate lifting right arm/left leg (B) and left arm/right leg (C) without touching them down to the mat. Count slowly from 1 to 10 as you swim, lifting higher and reaching longer with each progressive count. Sit back on your heels for a counter-stretch in your lower back, if needed.

Eating while riding means you’ll be less likely to indulge in the post-ride binge. We’ve all experienced this voracious state at least once. It’s that moment when you get home feeling so depleted and starving that an entire bag of Cheetos seems to disappear in a matter of minutes. Eating while on your bike not only keeps you properly fueled and in a position for a more healthy recovery, but it also keeps you from stuffing anything and everything in your mouth after your ride.
Heavier people require more energy to move their bodies, which means they generally burn more calories. According to Harvard Health Publications, a 125-pound person cycling at 12 to 13.9 miles per hour will burn about 240 calories every 30 minutes, while a 185-pound person will burn 355 calories. If you increase your speed to 14 to 15.9 miles per hour, you can burn 300 calories at 125 pounds and 444 calories if you weigh 185 pounds.
Can't get rid of that extra fat around your thighs and butt? Fret not. When you do squats correctly, you engage your entire lower body and your core. Squats are one of the best bodyweight exercises to burn fat from the thighs and glutes, and get your lower body in shape in no time. Squats are popular amongst bodybuilders and athletes, because they work (and how)! Once you get accustomed to the regular type, you can alter the speed, maximise the reps, try new variations like jump squats, barbell squats, pistol squats and challenge yourself. 

Sprints outside, on a treadmill, or even up stairs or bleachers are great to burn the most calories in the least amount of time. No equipment is really necessary and you can do these workouts just about anywhere. “Sprinting is simple, and it burns huge amounts of calories—when looking to shed weight, it tops the list,” says Adams. “While steady-state running or jogging burns plenty of calories, increasing your speed and intensity will really pay off.”
To maximally reduce your body fat percent, you’re going to have to start in the kitchen. You may have heard the saying that abs are made in the kitchen, which is true - you can lose fat and not even pick up a single weight or run a single step. But in order to build muscle, increase muscular strength and cardiovascular fitness, you’re going to have to hit the gym. So, to stimulate as much fat loss as possible, your program will consist of 3 full body workouts per week (alternating between Workout A and Workout B) with 2 days of cardio and 2 days off.

Swimming is an excellent cardiovascular exercise that’s easy on your joints and more. Let’s take a look at how swimming can help you increase your fitness level and lose weight. Most of you probably know that cardiovascular exercise is one of the best things you can do for your health, but maybe you are dealing with achy knees, an injured back or weak ankles. There is always a way to exercise. We just have to work around your limitations and figure out what you can do.


Take a multivitamin. “Because you are removing grains, the majority of fruit, some vegetables, and a significant amount of dairy from your menu, a multivitamin is good insurance against any micronutrient deficiencies,” says Jadin. Depending on what your individual overall diet looks like, Jadin says you might also need to add a calcium, vitamin D, and potassium supplement.
Most outdoor activities are pretty dreadful when you bring them inside (see: running on a treadmill). But indoor cycling apps like Zwift, Sufferfest, TrainerRoad, as well as studio cycling classes offered virtually like Peloton actually make stationary cycling fun and entertaining. That means you’re less likely to fall out of routine when the weather turns bad.
