Carb Cycling: The Fit Cycle

Do you want to “lean up” without compromising your athletic performance? Do you want to train for long periods of time? Then the Fit Cycle is the cycle for you. The Fit Cycle not only eliminates fat, but it also supplies your body with the fuel it needs to perform successfully, no matter what sport you choose to excel in.

Unlike the other three carb cycles, the Fit Cycle only has two low-carb days per week, and there’s a very important reason for this: The extra high-carb day allows your muscles to absorb more fuel (glycogen), which you’ll need for maximum athletic performance. During your low-carb days, when this supply of glycogen gets depleted, your muscles will develop insulin sensitivity. When you then have a high-carb day or your reward day, these insulin-sensitive muscles will actually soak up more carbs, your body will burn this extra fuel instead of storing it as fat, and you’ll still lose weight. It’s an amazing process!

Here’s what a Fit Cycle week looks like:

With the Fit Cycle you won’t lose weight as fast as with the Turbo Cycle, but you will be able to maintain your athletic performance. However, if you do experience a slight decrease in your athletic performance with this cycle, and you’re not as concerned about losing weight, try combining the Fit Cycle with pre- and post-workout supplements or meal replacement shakes with some extra macronutrients.

And as with the other cycles, you can stay on the Fit Cycle or change cycles at any time. It all depends on your weight loss and athletic goals.

    I am a group fitness instructor and teach 15-18 classes a week. My question is how do I balance the high and low carb days to the level of workouts for certain days. Mondays I teach 2 high cardio and one low cardio class. Tuesdays I have a mix of toning and high cardio, Thursday is a rough day with 4 high cardio and a stretch class. Wed and Fri is mostly senior fitness or mat toning. Weekends I don’t work so if I workout it my choice of workout. I usually have my “reward day ” on the weekend. My goal is be fueling my body to build muscle to be lean and toned, I am not so worried about weight loss. I have a 4lb range I pretty much stay in. Should a high carb day be the day before or the day after a high cardio day? What level of activity should happen on a low carb day? Thank you for your help and advice. You are so awesome!

    • Team Powell - December 4, 2014

      There’s cardio built into each day (Monday-Friday) during each week, no matter which cycle you’re following. It sounds like the Fit Cycle is definitely the cycle for you, and here’s a post about maintaining your weight that might help: http://heidipowell.net/5137/weight-loss-maintenance/. You can move the high/low carb schedule a bit to better fit your workout energy needs if you’d like. For example, instead of beginning the week on Monday, you can begin it on Sunday or Tuesday. Just don’t change the order of the high and low carb days. Hope that helps!

    Dear Team Powell

    I am wondering what carb cycle I should do: I am an avid gym goer. I work out 60 minutes, 6 times a week. I have shed 40 lbs and have kept it off for 2 years. I am looking to shed the last 10 lbs that I first set my goal at. I am 5’6 and weigh 144 lbs. I want to shed these last 10 by Christmas time. Any advice would help!
    Thank you

    I am looking to start carb cycling. Most days I do my workouts at night. Do I save one of my snacks for after or add an addtional protein after or do something totally different? Thanks

  4. Roberto Cartagena - October 4, 2014

    How many carbs per pound should I eat? I have a pretty good athletic build. N just wanna try this out. I need to change my diet instead of my regular one that I’ve been on way too long. I’m not seeing any changes in my current diet. This looks like it will change me in a good way.

    Hello, I don’t miss an episode of your show! It inspires so many, me being one of them! I lost 50lbs and what I did was watch my calories with myfintesspal and use bodymedia to track what I burned. I’ve always wondered about carb cycling and after reading this I have a few questions. On reward day what does that consist of, one meal of your favorite food or is it all meals? And the portions are not based on servings but on using your hand to figure those portions out? Are they close to what the nutritional facts are on the label? Thanks for your time….I think to better my diet I’m going to try this.

    • Team Powell - October 2, 2014

      Great questions! 1. On reward days you can eat up to 1000 extra calories of any foods – nothing is off limits. 2. There’s a great graphic in this post that explains the portion sizes as well as other awesome info: http://heidipowell.net/4514/carb-confusion/. There’s also a great foods list beginning on page 192 in “Choose More, Lose More for Life,” that outlines some calorie-related serving sizes. 3. Nutritional facts on labels can have very different serving sizes, and the serving size can be different for two products in the same categories (cereals, for example). Hope that helps! :)

    Hi, Heidi!

    First, love the show! You & Chris are awesome! The transformations are so inspiring!

    I’m thinking about trying carb-cycling. I don’t need to lose weight, per se, but would like to reduce my body fat % from the current 25% down to about 20% (top end of athlete range for my gender & age – 49 yr old female).

    I’m a mom (grown kids), grandma to 1, have a full time office job, and am a certified personal trainer, running coach, & Insanity Instructor (evenings & weekends). I’m also a distance runner myself, currently training for 2 half marathons in October, and will be training for the LA Marathon (March) starting in November. I eat high carb most of the time since I expend A LOT of energy! So – obviously, I need to do the Fit Cycle.

    Currently, I track my food & exercise on the MYFITNESSPAL app. I aim for a calorie breakdown of 60% carbs, 25% protein, and 15% fat (every day). My question is, if I do the Fit Cycle, what % of my calorie take should be from carbs on high carb days & low carb days?

      Hi Cara: In carb cycling we don’t track percentages or grams – we use portion sizes. For this reason, I’m not able to answer your question. There’s a great graphic (as well as some other awesome info) in this post that might help you: http://heidipowell.net/4514/carb-confusion/. Good luck with all your races! :)

    • Cara Stone - September 18, 2014

      Thank you! Yes, the graphic is very helpful!

    Hi Heidi, I am a CrossFitter and was on a mostly primal diet, but I am finding that my energy is low and my performance is suffering a little. I do not like how wheat makes me feel and eat mostly sprouted grain products. I am trying to lose body fat and get lean, not necessarily lose weight (I am 5’6″ 132lbs), do you think the fit cycle could help me to break through this final plateau? Thanks for any advice! I absolutely love you and Chris and hope to someday help people in the same way that you do!

  8. Linda - August 27, 2014

    Hi ! You guys are Awesome! What about the hypoglycemic people that want to loose wight ?!! I am currently using a trainer 3 days a week and when I start my cardio my sugar can be as low as the 50’s or 60’s …. Any advice would be appreciated !! Thanks so much !

    • Team Powell - August 28, 2014

      It would be best to discuss Chris and Heidi’s carb cycling program with your healthcare team so they can help you make any necessary modifications for your hypoglycemia. It can be done!

  9. Ciera - August 17, 2014

    Hello Heidi, first let me stat off by saying thank you for taking the time out to read my comment an to make this blog post. i am 20 years old about 230 pounds 5’2 tall, i currently trying to lose weight. I stumbled across this blog post and today which i though was awesome, however Im confused as to what to do now. Yes i want to lose weight to lose weight but I also want to gain muscle and keep my curves. My question is which car cycle should i incorporate in my fitness routine and also is it possible to burn fat and gain muscle at the same time?

  10. Jenessa - August 11, 2014

    First off I love your book, your ago, and follow you religiously on Instagram & FB!!! I have a question I work out religiously 6 days a week running and lifting then interval training 2-3 days a week as well. Would this help me to lose weight that I want? I’ve plateaued for a year or so and work my butt off not literally at the gym!!! I need help and motivation I’m terrified to gain. I hope you’ll help answer my questions! Thanks!!!

  11. Tiffany - July 24, 2014

    Thanks for posting this. I have been thinking about buying your book for a while, but wasn’t sure if I would like the plan. I am really athletic, just completed my second marathon a month ago, but nutrition is my weakness. I would love to lose 5 pounds from my last pregnancy before starting a new one! i have upped my game with weight lifting to improve my physique, but I think to get the results I want I will finally have to make changes in the kitchen and stop blaming these 5 pounds on nursing! I think I will try the plan for a week or two and if it seems like a good match for me I’ll get the book. Love extreme weightloss; you and Chris are amazing people. Wishing you well!

    • Christa - October 22, 2014

      Quick question:
      How do you stray from those awful afternoon sugar cravings?

    • Team Powell - October 22, 2014

      Try chewing some minty gum, drink some water (sometimes thirst masks itself as hunger), take a walk or do some other form of exercise, do an activity you enjoy, or anything that will keep your mind off those cravings. And make sure you’re getting enough sleep too, because sometimes cravings hit because you’re sleepy.

    Hi!
    my problem is not my food portion so much but it’s staying motivated. I have lost 70lbs and gained more than that back in two years. I like walking and I would walk for hours but I just keep failing. I can give up the food easily but staying motivated is a struggle. I need to loose this weight so i will give this carb cycle a shot….. wish me luck

    • jason - July 24, 2014

      I have that struggle too. Im 36 yr old man 5’9″ 339.6. When I started to think about my health was when the dr said that I would end up eating myself to death. I have lost 31 lbs and still going. What I use for motivation is looking deep within myself and asking myself if I want to watch my girls grow up. I. Hope this helps. . If you need some more motivation hit me up on. My email pig weight @yahoo.com

    • Cara Stone - September 17, 2014

      Hi Pete-gaye ~

      When you feel your motivation lagging, remember why you started this journey. Your own personal ‘why’ can carry you through ANY workout and help you stay on ANY good nutrition plan (like carb-cycling).

      It would help to work with a trainer or at least find a friend who has a similar goal for added accountability. (Less likely to skip a workout if you have an appointment with someone).

      Always keep your goal and reason in mind! You can do this!

  13. Melody - February 19, 2014

    I just started the Turbo Cycle and must have missed this Fit Cycle. I would like to lose about 15 lb (currently 5’6, 155 lbs)but mostly, get lean and gain muscle so weightloss is flexible. I try to work out (I’m a lover of running!) for 30-60 minutes every day. What signs should I look for from my body that might suggest it’s time to switch to Fit?

  14. Julie - January 9, 2014

    Question: If I’m doing Insanity, the w/o, would I still be able to do a carb cycling diet for weight loss? I just can’t seem to lose weight anymore and I want to try something different! Thank you in advance.

    • JS - July 13, 2014

      I’m combining Insanity HIIT workouts with Chri and Heidi’s “fit cycle” diet plan…and so far so good. I have plenty of energy for working out and am losing weight. No real cravings or hunger. Diet is probably 80% of successful weight loss, and I’m very happy with the Powell’s nutrition plan.

      Chris’ workout plan seems very “solid”, and I’ll probably fully incorporate it into my workout in the future.

    • Cara Stone - September 17, 2014

      AS JS stated, for optimal energy, which you NEED for Insanity, I’d definitely go with the Fit Cycle!
