Carb Cycling: A Daily Meal Plan to Get StartedA strict nutritional regimen of low calories or low carbohydrates can be hard on the body and the spirit, especially over the long haul. For high-level nutrition lean cycle carb cycle, one solution to this dilemma is carb cycling. In the most basic format, carb cycling is lean cycle carb cycle planned alteration of carbohydrate intake in order to prevent a fat loss plateau and maintain metabolism along with workout performance. Carb cycling is considered an aggressive and high level nutrition strategy. Only people such as physique athletes whose nutritional adherence is extremely high, and who require a more meticulous nutritional approach, should use it.

A strict nutritional regimen of low calories or low carbohydrates can be hard on the body and the spirit, especially over the long haul. For high-level nutrition programs, one solution to this dilemma is carb cycling. In the most basic format, carb cycling is a planned alteration of carbohydrate intake in order to prevent a fat loss plateau and maintain metabolism along with workout performance.
Carb cycling is considered an aggressive and high level nutrition strategy. Only people such as physique athletes whose nutritional adherence is extremely high, and who require a more meticulous nutritional approach, should use it. Carb cycling is designed for short-term use. It is not a long-term solution for body fat management.
In fact, if used for too long it may be downright unfavourable. Although the body handles short-term deprivation relatively well, a strict nutritional regimen of low calories or low carbohydrates can be hard on the body over the long haul. For example, a recent study in the American Journal of Cardiology Horne et al noted that occasional and short bouts of fasting e. For example, as a result of long-term restriction, dieters may experience reduced metabolic rate, thyroid hormone output, sympathetic nervous system activity, spontaneous physical activity, leptin levels, and reproductive hormone output Douyon ; Friedl ; de Rosa ; Klein ; Ahima ; Weyer ; Mansell ; Kozusko ; Dulloo Not only can this have consequences for overall health, it can bring body composition gains to a standstill.
This is where carb cycling comes in. However, they can still lose fat if they still take in fewer total calories than they expend — i. Higher carbohydrate intake days can increase thyroid output and control hunger Douyon ; Friedl ; de Rosa Manipulating carbohydrate intake can also help one take advantage of certain anabolic hormones, namely insulin.
Insulin regulates amino acid and glucose intake entry into the muscle cells. If insulin is seldom elevated, dieters will not reap its anabolic benefits. There are different methods of carb cycling. However, the common theme behind them is that protein and fat intake stay relatively constant while carbohydrate intake is manipulated.
Carb cycling also typically involves calorie cycling. Since carbohydrates have 4 calories per gram, adjusting carbohydrate intake while keeping fat and protein more or less the same can greatly alter calorie intake.
Berardi gives a nice definition of re-feed as a planned increase in calorie intake that lasts 8 — 12 hours and usually consists of a large increase in carbohydrates. Re-feeds usually occur when dieting and are scheduled in order to provide a brief day of psychological relief as well as a number of physiological benefits.
An example of a re-feed is following a strict diet of kcal 5 days per week and consuming kcal of clean bodybuilding foods the additional kcal coming mostly from carbohydrates on the other 2 days.
Since carbohydrate intake will be increased on the re-feed days, it is important to scale back the fat and protein intake slightly. Carbohydrates have a protein sparing effect so less dietary protein is required. This consists of structuring different menus with moderate carbohydrate intake at strategic intervals during a lower carb intake phase.
This approach steers away from an extremely high carbohydrate intake because the menu changes regularly. But it does allow for metabolism to play catch-up with dietary intake. Those interested in gaining muscle mass need a calorie surplus.
Thus, one way to optimize muscle gain over fat gain during a muscle gaining phase is with carb cycling. Menus are planned according to your weekly schedule in order to create a temporary calorie surplus. This can assist with lean mass and strength gains. Carb cycling may help control leptin and ghrelin levels. These are appetite and fat homeostatic hormones — in other words, they are sensitive to body composition and food intake; their job is to try to make sure we eat enough and have enough body fat.
With a lower carbohydrate intake, fiber intake will also be lower. Make sure to consume high-fiber foods and supplements and drink plenty of water to prevent constipation. Our next group kicks off shortly.
