Lost 5lbs in 48 hrs - Intermittent Fasting

deimosphoebos · March 2018

Has anyone experienced this?

I have been consistently losing weight (2lbs/week) over the last three months, and yesterday I began intermittent fasting 16/8.

At my weigh in yesterday I had lost 3lbs, and today another 2lbs.

The only change to my routine was limiting my food intake to that 8 hour block, I have even been eating more than my avg caloric intake these last few days.

Has anyone experience similar effects with intermittent fasting?

Thanks ahead of time for any input.

HAVE you been tracking your calories over the last three months AS WELL AS the last 48 hrs?

IMO you're either more dehydrated or you ate less sodium. Have you been drinking during your IF?

Lost 5 pounds of what, that's the question.

I have been tracking all my calories religiously over the last 3 months as well as the last 48hrs.

I am not drinking more water than usual, I normally avg 8-12 cups per day.

My sodium intake also is not that different that it usually is.

I expect I will have more info once I continue with this routine for two weeks.

So how much higher is your caloric intake?

Like 500ish more than I aim for. I aim to eat 2400 cals a day, and with my current activity levels that is a 1000 calorie deficit. The last 3 days I've had an intake of 3000-3200 cals

My diary is public if you guys want to take a look at it

It happens. These are just blips. I lost and regained 5 lbs in the past 3 days. If you've been eating more, it's possible that your stress hormones went down and along with them some chronic water retention. It also appears you've been less active unless you haven't logged your exercise in the past couple of days. That too can lead to the shedding of some water weight.

My activity has not decreased, I just turned off my exercise calories. I'm letting my FitBit track that data.

Weight fluctuations happen for all different sorts of reasons. There's lots of stuff in your body other than fat, and that stuff waxes and wanes every day. You didn't lose 5 lbs of fat in 2 days, it's not physically possible.

You've been losing weight rather quickly, that can have all sorts of effects on your body as well. I would guess its a coincidence that the loss happened when you started IF, but there's no way to really know what happened or why. Don't be surprised if you gain some of it back soon, but enjoy the lower number on the scale anyway

I hate you!!! 3000 calories?! Really?! I've got nuthin on the subject.

Jthanmyfitnesspal · March 2018

But seriously: I have had up to 5lb fluctuations from a number of things, notably a long (multi-hour) endurance effort.

My fluctuations normally don't go beyond 2lbs. The last time I had a drop like this was when I began my journey (I lost 10lbs in 6 days).

Its not possible to drop 5 pounds of real weight from IF alone in 48 hours. IF is just an eating schedule no magic formula. Add in the fact that you ate more than you normally do on these two days.

I was thinking maybe you were due for a whoosh, but you said you were losing a steady 2 pounds a week?? All kinds of variables at play... you ate closer to maintenance calories for two days, if you possibly were a little lighter in your exercise/activity add in glycogen replenishment needed, you did not drink as normally you do, hormone resetting from eliminating an aggressive calorie deficit. It usually takes more than a couple of days, but I don't know anything about your exercise and weight loss history as of this.

Give it a few days, this will all come back, unless a couple of these pounds is is your 'normal weekly expected loss' then you will gain back 3-4 pounds of water.

Sounds good. From what everyone is telling me, it does seem more like a coincidence. Thanks for the input

Nice...5 pounds!
I have experienced eating low calorie many days in a row and all of a sudden one day i over eat my goal by at least 500. The very next day i drop a couple of pounds.

lynn_glenmont · March 2018

Well, there's the theory that your aggressive calorie deficit over the last three months increased your stress hormone levels, leading to water retention, and the more moderate deficit of the last couple of days reduced the stress hormone levels, leading to a water whoosh.

Look up intermittent fasting. what you've experienced is normal. My sister is on her second week and she has dropped 9lbs last week.

gophermatt · April 2018

Tried IF, didn’t change my rate of loss at all overall, but my intake was further away in time from my weigh ins. If IF is helpful for you to maintain a deficit, have at it. Some people really like it. The whooshes are a great feeling. I dropped 8 lb in 3 days when I changed my exercise regimen. Felt great, but I knew darn well most of that was coming back, and it did with the exception of the pound or so per week I can drop on my deficit.

Good luck and have fun learning your body. We’re all a bit different, find what works for you to maintain a deficit!

It's just changing your eating schedule. What's the big deal about long term effects? It's like if you skipped breakfast for a few years and then decided you weren't going to skip breakfast anymore.

People are making IF seem like it's some huge life-changing deal when it's nothing of the sort. You're eating one less meal and cramming the calories into a shorter time frame for the rest of the day. If your body can adjust to that, surely it can un-adjust to it just as easily if you ever decide not to do it anymore.

You can lose a significant amount of weight and fat on any diet which involves consuming less calories than you expend. Because that's how weight loss works.

I agree about IF...it is just an eating schedule. I have an early supper on average so done by 5:30 then nothing else for the rest of the night..then I just skip breakfast and don't eat until lunch which is about 11:30 ish give or take.

I know lots of people who do not have weight issues and I find that they seem to all have some of the same habits, i.e. not eat after supper, skip breakfast or just have a smoothie for breakfast, etc.

I am extremely interested in this diet plan.

I believe you can lost a significant amount of weight and fat but I’m not sure about the long term effect. I don’t think you can eat normally again because your body is already accustomed to the diet. Unless, you are going on intermittent fasting for the rest of your life?

I’ve actually tried a similar diet called OCD, it’s a diet where you can eat anything from 1pm - 5pm and then fast. I lost 2kg in a week. But due to my low blood plessure, I quit the diet and my weight bounce back.

Exactly....it is definently not radical! I am usually done supper by 5:30 p.m. and then have nothing else for the rest of the evening, then bedtime, then I skip breakfast.

Great if you can get a workout in as while before you start eating again.
