The Case For & Against Carbohydrate Cycling for Fat Loss

We don't just review the best home gym equipment on this site, we also care about nutrition because it is an essential component of any fitness regime. In this article I discuss the pro's and con's of losing weight by Carb Cycling. You may have heard about this method, if not read on for some insight nd my personal conclusions.

To lose fat you have to underfeed, and because protein and fats have essential uses within the body, restricting the number of calories from carbohydrates is the obvious place to start. But is it really that simple? Restricting carbs for long periods of time can have negative effects on the body, and this is why many people turn to carb cycling; a low carb diet that enables you to maintain your metabolic rate whilst burning fat

About Carb Cycling

Carb cycling is the process of alternating periods of low carbs with high carbs to prevent a fat loss plateau whilst maintaining your metabolism. There are no set rules but here are a few quick examples:

1. Infrequent High Carb Days

Perfect for: those with good discipline and low cravings

This is a low carbohydrate diet that allows you to go to town on the carbs once every 7-14 days. Now when I say go to town on the carbs, this is of course within reason. Our overall goal is still fat loss so it’s important to try not to have more than 3 – 3 ½ times your normal daily calorie intake.

Extra tips:

  • It’s easy to let the ‘re-feed’ days slip closer together due to social events or mental lapses, but it’s important to stick to your plan if you want to see results
  • Train on your high carb day so you can make use of those added calories
  • There’s no one size fits all plan. Regularly assess your body fat with a skilled practitioner; you may find a different strategy works better for you

2. Frequent Moderate Carb Days

Perfect for: those who battle with self-discipline and are prone to binging

If you find you struggle to stay away from carbohydrates for too long, or large ‘re-feeds’ sending you spiraling into days of endless binging, this option may be better for you. This again is a low carb diet, but allows you to increase your carbohydrates intake for 1 day every 3-4 days. The easiest way to stick at this is to increase your carb intakes on training days.

Extra Tips:

  • Every 3-4 days eat meals that are similar to what you would usually eat, but add in some carbohydrates with each meal. This way you’re less likely to binge on junk
  • Focus on high quality carbs such as fruits, potatoes, rice and beans/legumes
  • Try not to go over 1 ½ times your normal daily calorie intake

3. Mixed Carb Days

If you’re already quite lean but struggle to keep onto muscle this maybe the best option for you. It just takes quite a bit of preparation and thought as you won’t be eating the same every day. This strategy uses 3-4 different menus of varied carbohydrate intakes over the course of a week. You would use low, moderate and high carb days.

Perfect for: those who are already quite lean but struggle to hold onto muscle.

This option takes a little more preparation and thought as you won’t be eating the same thing every day. Using 3 different menus of varying carbohydrate intakes over the course of a week, you will have low, moderate and high carb days.

Extra Tips

  • Schedule your high carb days on days where you train with high intensity (save it for a big squat day)
  • Plan your 3 types of menu ahead of time – this one is important for those who find it hard to stick to a plan
  • For maximum fat loss effect, have more low carb days
  • When lowering your carbohydrate intake you should generally increase your fat intake and keep your protein consistent, as long as it’s sufficient

Carbohydrate cycling is an effective method for fat loss, and done correctly you could quickly see the benefits whilst managing the negatives. Individualism of diets created by a professional is the key to succeeding, get it wrong and it could be detrimental to your health and performance.

Your body is smart and hormones will be working against you, doing everything possible to stop you starving yourself to death.

The Case Against Carb Cycling

The strong case above shows that carb cycling is mostly beneficial from a training, social and psychological aspect, but what about the evidence on hormones and metabolism?

In this instance a more moderate reduction in carbohydrates would be more appropriate and effective. This is also the case for those who are unconfident and unskilled in the kitchen.

There are some added health benefits if you can stick to this way of eating, such as reduced risk of cardiovascular disease although these benefits may simply be down to overall weight loss.
