Aggh what is happening?

Could it be that your take out meal has a large amount of sodium? It takes me several days to get my weight back down after a high sodium meal.

First of all, you don't gain 1.5kg of fat overnight. It is perfectly normal for your weight to fluctuate every day, and it can fluctuate quite a bit. So don't worry about that.

Second, I agree with the second poster and think you are under eating. As a comparison: I weigh 53kg (at 1.52m) and I eat around 1500 calories to lose weight, around 1800 to maintain. You are heavier and most likely taller, and definitely more active than me so you need more calories than me.

I did Weight Watchers for years and honestly thought I was losing weight the healthy way. Earlier this year I quit WW, and found MFP. I was shocked to find how little I was eating on WW, just about 1000-1100 calories a day. No wonder I was always tired and hungry.

Here on MFP I read about the TDEE method. TDEE is the amount of calories your body needs to maintain the weight. This number is based on your age, height, weight and activity level. You then eat between 10-20% less than that for weight loss.

So I decided to give it a try and upped my calorie intake. In the beginning my weight fluctuated a bit within the same kg, but it has been going down since. I eat at a small deficit because I don't need to lose a lot more. But I am actually eating lots more than on WW and still losing. To be more precise: I am at my lightest weight in about 13 years.

If you eat 1300 calories and don't eat back your exercise calories, you are netting even less than that. It means that technically you are only eating 800-1000 calories. Your body needs way more than that simply for the energy needed to keep your organs working.

I know it's really scary to go up in calories, but look up the TDEE method and read some of the success stories :-) Good luck!

More data is required! Are you eating back your exercise calories? How tall are you? 1300 to maintain is very little calories, actually. You may have lost a lot of lean body mass doing WW. But we can't really help unless you give us more stats and open your diary.

Depending on your age, weight, sex, you could be vastly under eating. So.. fill us in with more data.

OR OVEREATING. Which, since there is a weight GAIN, is much more likely. :grumble:

God, are you always this cranky?? I DARE you to look at this and NOT LAUGH!

Who's cranky? Cute critters by the way.

But I get tired of the FIRST piece of advice for a person who "can't seem to lose weight" always being "you need to eat more calories! Mmmmmmm!". If a person is not losing weight, and is in fact GAINING weight, that person is in all likelihood eating PLENTY of calories, they just don't realize how many they're really eating. That should be the first thing checked. But no, people assume people self-report their calories in and calories out with extreme precision, and just spout the Eat Moar Caloreez mantra like they're getting paid to do it. :grumble:

puhleazeeeee...read through the posts and think...before...you.....post. >>1300 calories a day<< IS low and very well could be the reason she isn't losing like she wants.

You're really bad at math. When you eat FEWER calories, you LOSE weight. When eat MORE calories, you GAIN or MAINTAIN weight. Math. You know that you're not making math work for you when you're not losing weight. See how that works?

And people notoriously underestimate the calories they consume. It happens. "What, I'm supposed to count vegetables?" "What, I'm supposed to count beverages?" "What, I'm supposed to count candy?" :huh:

. But no, people assume people self-report their calories in and calories out with extreme precision, and just spout the Eat Moar Caloreez mantra like they're getting paid to do it. :grumble:

If I lose weight at 1500 calories, being 5' and weighing almost 60lbs less than OP, and she is trying to MAINTAIN at 1300 calories, you can't seriously think that she is overeating.

Clearly you missed the point. Just because she SAYS she is eating 1300 calories/day doesn't mean she actually is. If you are eating at a deficit you CANNOT gain wait. It is against the laws of thermodynamics for god sake. We should first ask the OP... are you weighing your food, logging every single bite that enters your mouth, etc, etc, etc... I'm here to tell you that if you eat at 1300 calories/day you will lose weight. Period. Unless you are 3 feet tall and weight 60 pounds.

One person has lost 160 the other 14.... I am pretty sure I know who I would listen to.

You can easily gain weight eating at a deficit. Fat, no, but weight, yes.

There are also plenty of people taller than 3' who will not lose weight on 1300 calories. Physiology is a very complicated thing. There are mechanisms in place which, when faced with an extreme or prolonged calorie deficit, seek to minimize the negative consequences of under feeding by downregulating metabolism through both physiological and behavioral mechanisms. I don't know what's going on in the OP's case, but it's incorrect and overly simplistic to say that the only possible reason is that she's actually eating twice as much as she thinks she is. Sometimes, advising people who have been chronically undereating to eat even less is very dangerous advice.

It isn't even clear how much weight the OP needs to lose -- she said she was maintaining at 80kg and is now at 82kg and trying to lose -- if you only want to lose a few pounds, eating at that big a deficit is definitely counter productive.
