How long does the body need to adjust to a calorie increase?

bump

I followed IPORM and I gained about 10lbs over 4 weeks. Then my body started to slowly adjust and I started to drop again. Don't get discouraged. It's part of the process. I do heavy weight lifting and there is no way 1200 cal is enough.

I can assure you that if I did not find these posts I would have probably been very very discouraged. I too was a member of the 1200 club for a long while. I lost over 50 lb since Aug 2012, but stalled out...OMG, I have been stalled for WEEKS. I have recalculated my BMR and TDEE and I should be at about 1700 so I increased or I am doing my BEST to eat that for the past 1.5 weeks or so. I also adjusted my macros (higher protein)...wow, that is really hard. I am finding that the only way I will be able to get 40% protein in each day is to do protein shakes. I am not a weight lifter...although I would love to....I am just a walker...yawn...boring, I know. I am SOOOOOO afraid to get on the scale.... I have 20ish to go....
At any rate, thank you for all of your valuable input! I really needed it!

Hi all,

For about 4 months I was on MFP's "suggested" 1200 calorie limit, and while I have lost a pretty good amount of weight, I started to notice my body needed more coz of all the lifting/working out I do (Cardio/lift 5-6x a week). That, plus a bunch of research have led me to do a calorie increase. I am now really wishing I never followed the 1200 limit as I feel like my body is taking longer to adjust to the increase. What I mean by this is that I've gained a couple lbs back. It's probably the muscle increase mostly, but I figured I'd ask here to make sure I'm understanding it correctly.

Okay, in all honesty it's been about 2 weeks since the calorie increase, I just really want to know if it's still normal. At this point, it's more about dropping my body fat percentage and increasing muscle mass. Thanks to my awesome scale, I do know that my muscle mass is coming up.

Any shared experiences are greatly appreciated .

I am in the same situation. I have for 2 weeks done TDEE-20% and cant say that I have seen or felt any change. I know it can take some time but my mind is doubting me

I'm following this plan for how many calories to eat:

For fat loss, you want to aim for a range of daily calories that is calculated based on your bodyweight (in pounds) as well as other factors.

To lose fat: 8 to 12 times bodyweight
To stay the same, neither losing nor gaining (also known as maintenance): 13 to 16 times bodyweight
To gain mass: 15 to 20 times bodyweight
You will notice that these are fairly broad ranges. This is because the precise intake will depend on other factors besides your general goals.

Aim for the LOWER end of the range if you are:

female
older
less active
starting out at a fairly high level of bodyfat
Aim for the HIGHER end of the range if you are:

male
younger
more active
starting out at a lower level of bodyfat (e.g. only a few pounds of fat to lose, or trying to get from “normal” to “lean”)
For example, let’s say we have a 150 lb. woman who is in her 20s, fairly healthy and active, and who just wants to lose a few pounds of bodyfat. Her intake might ideally be somewhere between 10 and 12 times her bodyweight.

10 x 150 = 1500
12 x 150 = 1800

So, that means her daily intake of calories should be between 1500 and 1800 calories per day. Don’t forget to adjust intake downwards as your bodyweight drops. For most active women, probably somewhere between 9 to 11 times bodyweight to lose fat is about right. But feel free to tweak things up or down a little as you require.

I upped my calories like 2 weeks or so ago.. i'm really struggling to eat enough though, I was struggling at 1200 even.. However I also got my monthly cycle the week after I upped it.. So ican't give an accurate assesement of weight gain due to one or the other. LOL.

Damn femaleness...

Anyway.. I think the measurement thing is a great idea.. I stopped losing weight a bit back.. but my pants are still getting looser and I can feel the muscles getting stronger and tighter. I need to measure again.. but not this week! LOL

I can't get it down.. one day I do great.. reaching my goals only to feel full and bloated the next and totally miss my goals by a lot. Plus I exercise a lot.. so I probably still have my goals to low.. but baby steps lead to success right? Come hell or highwater I'll get this done! LOL

I'm at 1890 cals/before exercise! Eat da foods! Your body will adjust, different people will have different adjustment periods, just be patient... It's worth it!

I've recently gone from 1400 to 2160 as I was under eating, I now do TDEE - 20% and that is 2820 for me but I've not gone up that high yet, my weight is still stagnant after 9 days but I'm starting weights next week so we shall see!

My weight is still stagnant at 2160 I might up it now?
