Just remember, the quality of the carbs you eat still matters, so continue to focus on minimally processed, whole-food carb sources. The science of carb cycling while following a baseline low-carb diet is still in its infancy. The key is to understand your goals and monitor your progress. Guide How few carbs are there in a low-carb diet?
It depends. Guide Are you struggling to lose weight? Have you come here looking for tips to blast away belly fat or lose weight quickly and permanently? Or maybe one of these conditions runs in your family. Some experts believe that the explosion of diseases like type 2 diabetes and cardiovascular disease are largely related to recent changes in the human diet, brought about by modern agriculture and animal husbandry.
The argument goes that we are not genetically adapted to eat so much grain, milk, and domesticated meat. Here is an article describing this position. As mentioned earlier, the science on evolutionary nutritional patterns is flawed. This is based on consistent clinical experience of low-carb practitioners. The topic of food addiction, and specifically carbohydrate addiction, is an evolving field that suffers from the lack of a uniform definition.
The following is a review of the topic. This is based on consistent clinical experience of practitioners who use low-carb diets. This is based on the consistent clinical experience of low-carb practitioners.
Diabetes Classification and diagnosis of diabetes mellitus and other categories of glucose intolerance. International Journal of Sport Nutrition and Exercise Metabolism High-fat diet versus habitual diet prior to carbohydrate loading: effects of exercise metabolism and cycling performance [randomized trial; moderate evidence]. Metabolism Keto-adapted athletes increase fat oxidation and preserve muscle glycogen.
Metabolic characteristics of keto-adapted ultra-endurance runners [nonrandomized study, weak evidence]. Sports Medicine Strategies of dietary carbohydrate manipulation and their effects on performance in cycling time trials [overview article; ungraded]. The following study showed that 12 weeks of keto-adaptation helped exercise performance and body composition. Metabolism Keto-adaptation enhances exercise performance and body composition responses to training in endurance athletes [nonrandomized study, weak evidence].
And the following three-month pilot study of CrossFit athletes found no significant change in performance when on a keto diet vs a normal diet. Sports The three-month effects of a ketogenic diet on body composition, blood parameters, and performance metrics in CrossFit trainees: A pilot study [randomized trial; moderate evidence]. Two studies from Dr. Burke and colleagues showed reduced kilometer race walking performance after 12 weeks on a keto diet.
Journal of Physiology Low carbohydrate, high fat diet impairs exercise economy and negates the performance benefit from intensified training in elite race walker [randomized trial; moderate evidence]. PLOS One Crisis of confidence averted: Impairment of exercise economy and performance in elite race walkers by ketogenic low carbohydrate, high fat LCHF diet is reproducible [randomized trial; moderate evidence]. Journal of Sports Medicine and Physical Fitness Low-carbohydrate, ketogenic diet impairs anaerobic exercise performance in exercise-trained women and men: a randomized-sequence crossover trial [randomized trial; moderate evidence].
Nutrients The effects of a ketogenic diet on exercise metabolism and physical performance in off-road cyclists [randomized trial; moderate evidence]. Journal of Applied Physiology Fat adaptation followed by carbohydrate loading compromises high-intensity sprint performance [randomized trial; moderate evidence]. One proposed explanation is the decreased oxygen efficiency of burning fat compared to burning carbohydrate. In other words, carbohydrate yields more energy per liter of oxygen compared with fat.
So, fat-adapted athletes on a low-carb diet may be better at using fatty acids to power their muscles, but this benefit may be offset by the need to consume more oxygen to generate this power. This may result in a net negative or neutral effect on performance, compared to their higher-carb peers. The following paper reviews how MCT oil plus carbs slow depletion of glycogen in fat-adapted individuals, or those whose bodies have learned to burn fat for fuel instead of carbs.
Journal of Sports Science Nutritional strategies for promoting fat utilization and delaying the onset of fatigue during prolonged exercise [overview article; ungraded]. And the following mechanistic study shows that fat burning muscles can maintain that physiology for a few days even after eating more carbs. The type and intensity of exercise also likely play a role, given that carbohydrate availability seems to be even more important for shorter, intense bursts of activity.
American Journal of Clinical Nutrition The impact of keto-adaptation on exercise performance and the role of metabolic-regulating cytokines [overview article; ungraded]. Longer adaptation is based on the consistent clinical experience of practitioners familiar with low-carb nutrition. Scandinavian Journal of Medicine and Science in Sports Fueling strategies to optimize performance: training high or training low? An oral glucose tolerance test, or OGTT, involves a fasting blood sugar test.
You then drink a gram carbohydrate drink and repeat glucose testing at one and two hours to see how high your blood sugar climbs. I added calories to both my high- and low-carb days, bringing my high-carb days back to my usual 1, calories and my low-carb days up to 1, I hoped that would be enough to power my workouts and help me build muscle, and maintain a fat-loss-friendly caloric deficit on my off days. I stuck with my same go-to foods, just ate more of them—though the extra calories also gave me some wiggle room to eat out and not have to order a dressing-free salad.
By the time I got my workouts back on track, I had just two weeks of my little experiment left. The new calorie counts felt really doable, and as I got more familiar with the calories and macros in different foods, I was able to follow my carb-cycling plan without tracking throughout the day.
Facebook Instagram Twitter Pinterest. Search for:. Me, before a month of cycling carbs. Getting Started I decided to use MyFitnessPal, which lets you set unique different calorie and macro goals for different days of the week, to track my food.
Tweaking My Approach By about two weeks in, I felt a little less bloated a common issue for me. Sure enough, within a few days I was lifting my normal weights again! Final Thoughts…and Results By the time I got my workouts back on track, I had just two weeks of my little experiment left. Eat the majority of your carbs early in the day and at the post-workout meal, tapering off as the day goes on.
Don't worry about the glycemic index of the foods, just focus on keeping total carb intake for the day at your target level. These are the best sources of clean carbs to include in your meal plan when dieting in general, and when you carb cycle:. The only time to eat simple carbs is at the post-workout meal, when you should take in 50 grams of dextrose with a whey protein shake immediately after training.
Add these carbs into your daily total, because even though they're utilized efficiently by the body at the post-workout feeding, they're still carbs. Sugar-laden junk foods are always bad and should have no place in your diet, not even if you're carb cycling.
Quitting junk food altogether can be a lot to ask, but the more you cut down, the more you'll lose body fat. Try to cut back on junk food gradually until it is totally eliminated from your diet, except for the rare treat.
You'll probably find that once you stop eating it you won't miss it as much as you'd expect. It's common to hear "everything in moderation," even with dieting.
The idea is that if you're too strict, you'll feel deprived and won't stick with the diet. But with carb cycling, as with any diet, if you have aggressive fat-loss and muscle-growth goals, such as for a bodybuilding competition, moderation can get in the way of success.
Terms like "refeed," "cheat meal," and "cheat day" almost always come up even in this article. These ideas can be used to your advantage, but it's best to wait until you're pretty close to achieving your desired body-fat percentage before even thinking about them. Simply put, you must make some sacrifices and give up all unhealthy eating habits if you want to succeed in losing fat or winning a contest! Flip the switch in your mind to eat "clean" and don't even think about giving up.
There can be no half measures. Getting your carb counts right is important, but a huge part of diet success is getting in the proper mindset and staying completely focused on achieving your goals. How much weight you lose carb cycling is a matter of how strictly you follow the program and how much you can avoid junk carbs and excess fat.
