In fact, once all our our reserved glucose/glycogen runs out after several days on a low-carb, keto diet, our bodies create compounds called ketone bodies (or ketones) from our own stored body fat, as well as from fats in our diet. In addition, researchers have discovered that ketones contain main benefits, such as fat loss, suppressing our appetites, boosting mental clarity and lowering the risk for a number of chronic diseases.
OK, that’s all good but you still need to hit your “climbing” weight. Well, as Eddy Merckx rather eloquently said, “Eat Less, Ride More”. Don’t we all wish. Basically it all comes down to taking in fewer calories than your daily caloric requirements, otherwise known as a caloric deficit. Some athletes can successfully ‘diet by math‘ to lose weight and if you want to try, I recommend a 500 calorie caloric deficit per day. Over 1 week that is 1 lb. 10 weeks = 10 lbs. Don’t diet more than that because your power on the bike and recovery off the bike will decrease.
These machines were originally designed to minimize impact on the knees and hips, but still allow a great workout. “Because the impact is quite low, the calorie-burning effect isn’t as great as other cardio machines, like treadmills and stairmasters,” explains Roger Adams, Ph.D., an expert in nutrition and weight loss. “However, the elliptical machine can be an excellent way to burn calories without wearing out your joints.” While the average 180-lb. man may only burn close to 500-600 calories per hour if he’s going at an above moderate pace, you can get even more out of it by switching up the intensity, speed, and resistance.
Yes, you lose weight when you cut calories, but pounds lost aren’t always fat. Some of your weight loss may also come from muscle tissue. Cyclists that diet often end up thinner, but risk becoming slower and weaker on the bike. As pioneering diet expert Covert Bailey once wrote, “When someone says that they lost 20 pounds, the key question is: 20 pounds of what?” Some dieters can end up having a higher percentage of body fat even as they lose weight. And don’t forget that muscle burns calories. The more muscle volume you have, the more calories your body can burn—even when you’re just lying on the couch.
