• High-protein ketogenic diet — This method is a variant of the SKD. In a high-protein diet, you increase the ratio of protein consumption to 10 percent and reduce your healthy fat consumption by 10 percent. In a study involving obese men that tried this method, researchers noted that it helped reduce their hunger and lowered their food intake significantly, resulting in weight loss.11
So what makes cycling so special for weight loss? In short, it makes you happy, says Jimmy Weber, of Enid, Oklahoma, who at 6’2” and 260 pounds is not a small rider, but is now 150 pounds lighter than his max weight of 410 pounds eight years ago. He initially shed weight through bariatric surgery and a lot of walking. But walking his usual seven miles a day got boring and running was out of the question.
When you're on the elliptical or stationary bike, or you're running on the open road, play something like "Right Here Right Now" by Fatboy Slim, "Ice Princess" by Azaelia Banks, or "Circles" by I See Monstas — three songs that SoulCycle instructor Lily Miesmer likes to play during the interval portions of her classes. With brand new songs, your mind doesn't know what's tempo is coming, so your body won't either. And working hard to keep up when that beat drops will increase your overall calorie burn.
4. Do not fear weights. While lifting weights won't necessarily burn fat, it will build muscle. The more muscle you have, the more calories your body burns after you leave the gym and plop down on the couch, Jackowski explains. Another thing: Weight training keeps your muscles in shape so they looked toned when you shed the fat that's now covering them up.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.
• Cyclic ketogenic diet (CKD) — Whereas TKD is focused on fitness enthusiasts, CKD is focused more on athletes and bodybuilders. In CKD, you cycle between a normal ketogenic diet, and a short period of high carb consumption or "re-feeds."8 The idea here is to take advantage of the carbohydrates to replenish the glycogen lost from your muscles during athletic activity or working out.9
The research is pretty conclusive: Most people who exercise only because they know they should don’t stick with it—at least not for very long. Up to 80 percent of people who start exercising throw in the towel within a year. The novelty quickly wears off, and they become bored and find things that are more fun to do. But riding a bike makes you feel like a kid. You can go places and explore, pedal through pretty scenery, and feel the fresh air wash over you. You can ride with friends or family or relish in some alone time. You’re not looking at the clock willing your obligatory 30 minutes to go by. You’re enjoying the ride. Oh, and getting some exercise.
