Fluctuating Calorie Intake... Good or bad?

I have read some places that it is good to fluctuate your calories weekly. For example

Monday:1600
Tuesday:1200
Wednesday:1700
Thursday:1500
Friday:1300
Saturday:1500
Sunday:1600

I heard it is good to keep your body guessing. But is this a good way to do it. I know I have
a really hard time keeping on a solid 1600 a day limit. I kinda want to do a varied calorie intake but what is your guys opinion? (the amounts were just random examples.. I dont think I would use those numbers)

    as long as your not going a couple of hundred either way, then its fine, it will be the average of the week that really counts, if your averaging your weight loss calories, then you will be fine, if your way over on your average, then you need to look at it and address the problem or find out where the problem is. Hope that helps.

    Not really, how does your body guess?

    If you associate this with activity it might help on performance otherwise just do whatever is easier to adhere to.

    Okay so what you are saying is as long as I average 1600 (my goal calorie intake at his time) at the end of the week it is all good?

    I suppose guess isnt really the right word.. More like it cant get use to the same thing all the time. Like how you have to change up your work outs so your body doesnt get use to it.. Does that make more sense?

    I think fluctuating calories is the most natural option, and I let it happen by itself when I was losing.

    As long at the end of the week your average net calories from week to week are the same.
  • This could definitely be good if you enjoy having a treat day, on a high-cal day, you could be able to fit in that chocolate bar you've been craving without destroying your week because you make up for it on a low cal day.
    Or it could also be good for not getting bored in general;
    You might not have a big enough cal budget on a 1200 day to eat your favorite lunch, but on another day it will feel like a treat, so you're always switching up what foods you eat.

    It's good if it helps gym performance and adherence. In itself, there is no direct impact on weight loss.

    Just looked at my weekly charts and I have been under my weekly caloric goal every week. So I guess Im not doing too bad. I just feel like crap if I go over the limit I set myself. I hate seeing that red number.

    I kinda like seeing the red number when it's on protein. wonder if that's actually good, tho?

    It's called calorie cycling. And apparently it does help with boosting your metabolism, since your body never knows how many calories to expect on any given day, it can't stabilize/slow down, etc. As long as you meet your weekly calorie goal, you can fluctuate your calories daily. I discovered this accidently during the holidays, when my calories were all over the place. I lost more by unintentionally calorie cycling, than when I was eating the same amount of calories daily. Google "calorie cycling" to learn more info...

    I have never seen anything outside anecdote that indicates that calorie cycling impacts weight loss. Refeeds at a low body fat do however. Most calorie cycling does not vary enough to be a refeed. The OP is not lean enough to see a direct benefit from a refeed anyway (sorry OP :flowerforyou: ) and the cycling is not extreme enough to actually be considered a refeed in this example in any event.

    Thank you. To be honest, the most important thing is adherence and how you feel. What will make this easier? If varying your calories will, then do that.

    When cutting, I varied my calories based on my lifting days - more calories for lifting and less for not lifting. I liked it from an energy perspective but also it enabled having a couple of 'more relaxed' eating days in the week. I still tracked, but I could eat with less restriction on calories - that helped adherence for me.

    You are correct. That is why I believe in macros ranges instead of static macros.

    Eh. For what it's worth, I do calorie cycling. And I've lost over 50lbs, and am at 15% BF.

    It worked for me in combination with some hardcore cardio training and heavy lifting.

    I will respond in the thread more fully and with a better answer but to be honest, it is really hard to assess with any degree of accuracy above about 30%. What really matters is that you are doing the 'right things' to lose weigh and that the weight is as much fat (as opposed to muscle) loss as possible.

    Eat at a reasonable caloric deficit, get enough protein and do some resistance training, and you will be doing everything you can to get your BF% down. Longer term trends in scale weight (4 weekly cycles to take out water weight fluctuations as much as possible) as well as measurements and the mirror will tell you if you are making progress.

    Yeah. Could I friend you? I have a huge lack of modivation/support here at home. I try to stick to a diet.. Then the bf brigs home something I have a hard time resisting (mainly sweets) and I get knocked off track for weeks. :(
  • Maybe this is a totally stupid question. But bare with me. I`m new to all this.

    Does this mean that if i eat few calories during the weekdays, Can I then have binge day (Saturday) where i can eat some more calories as long as my week is under as a total?

    Even if I go over my limit on the binge day?

    As long as everything averages out for the week, then it will not make an appreciable difference in the long run, assuming your total week is the same. However, this assumes some common sense in that the weekday calories are not so low as to not be getting proper nutrition (including hitting protein and fat targets) or to be creating a very large deficit.

    Totally. The biggest culprit is to allow the odd bad day here and there to derail everything. Also, working on setting an appropriate target that is achievable in the long run, but still allows for this type of thing (within reason) is very important imo.

    Lol. Thanks. Maybe you can whip my butt into shape :)
    Just did my BMR. Says with my activity level I should eat 1300 calories a day. Makes sense. Now lets see if I can do it. (1600 was close to a 'maintain weight' goal)

    Edited:: I just saw your settings. Your base of 1,600 is not to maintain. That includes a deficit. What weight loss target per week did you select?

    That seems really low.

    Can you PM me your stats (height, weight, age) and your activity - both day to day (e.g., desk job, running around after kids etc) and exercise, and I will try to work out a better number.
    Sure one sec

    Sorry - I edited my post after I realized that the 1,600 was your target (pre exercise). Still PM me your details though.

    Personally I have never tried this, but a guy on my friends list said calorie cycling broke him out of a year long plateau. One day he would eat at TDEE, the next at TDEE - 40%, and alternate. He said it helps to eat at TDEE every other day as your body isn't under pressure from a constant deficit.

    Personally I think it would be good for things social events or meals out, to have that extra calorie allowance knowing you will make it back the next day.

    Even though you may dismiss refeeds or carb cycling for OP since they're not lean enough if you've been on a caloric deficit for a long time breaks from such a "strict diet" can often help regardless of your current body fat. I have re-feeds or cheat days half structured and have not. If they come unexpectedly I adjust the rest of my week around it.

    If things are working fine, don't mess with it. I've only had to mess with my training because I still have bf to cut, but for some reason what I've done so far just stopped working. Going through different processes to find what works for you and not piggy backing others just because it worked for them is also important. The last time I plateau'd really hard I went back onto intermittent fasting and that helped. Unless you have a coach you're sending update pictures + measurements + stats there is no way for someone to help you calculate your most efficient macros.
