iv gained this week !! any ideas why ??

many things can play into this, water weight, time of the month espically. I usually don't track my weight during TOM cause it's usually anywhere from 3-6lbs heavier and as soon as it's past it's gone. But more than likely it's water weight from some source.

Drinking a lot of water (at least 8 glasses a day) will help with this whether it's the time of the month or not. It will fill you up and keep you hydrated. Don't get discouraged, try measuring your hips and waist. You may have lost inches and gain a little muscle or water weight.

i think it all depends on what your eating habits were before this. i know i was shocked at how much food i haad to actually eat once i started eating healthier and counting cals. if i were to go back to the way i ate, which was once, maybe twice a day, i wouldn't be getting enough cals even though all i ate was high cal food. so if that was what you were like in any way, your body may be freaking out a little bit at the amount of food it is suddenly getting. i wouldn't worry too much about a small gain unless it keeps happeneing consistantly over the next couple weeks. give your body time to get used to the fact that you are eating more food, but it is less cals, so it can happily start to let go of the weight.

I always gain about 2lbs the day after I eat too much sodium. You can go into your settings and add sodium to your food tracker and watch to see how it affects you daily.

It is impossible to gain weight if you are eating exactly how many cals MFP says, because MFP builds in a calorie deficit. If you eat less than you body spends moving and living, you will lose weight. The reason you gained would probably be:

1. You are overestimating how many calories you burn exercising, which is especially bad if you eat them back, because you will eat back more than you burned.

2. You are underestimating the calories you eat, for example, guessing food portions and being wrong, or rounding down instead of up.

3. You eat too much sugar and your insulin resistance is faulty, causing you to store fat

The less likely ones, since after a week these shouldn't matter as you would have lost weight anyways:

1. Retaining water. Eat less than 2000mg of sodium a day (make sodium a tracked nutrient on your food page) and drink more than 64 oz of water.

2. Period-related bloating and weight gain. Being on your period can cause temporary water retention and bloating that can make you gain 5+ "ghost" pounds that will go away when your TOM has passed. This doesn't happen to everyone.

3. Weighing yourself at a different time of day, for example, when you may still have food or poo in your stomach/intestines or pee in your bladder, or weighing with clothes on.

Edit: If you make your food diary public we can see what might be the problem :-)

Wow thanx so very much for your replys all very good suggestions I'm going to try not eat back my exercise for a week and see what happens. Also I'm going for a body assessment in 2 weeks to see if I'm losing body fat/gaining muscle. Also its just gone into spring here and very hot so iv gone from drinking very little water to 2.5l a day. Could this maybe also be why I'm heavier ? Thanx again 4 your help

No, drinking that much water will aid your weight loss and stop water retention. Your body only retains water weight when it think ti's dehydrated and isn't getting enough.

Oh ok thanx maybe I'm just being to eager to start losing. It has only been a week. I'm gonna play around a bit and see if I can find what works for me also hopefully the bod assessment will also help

Would you mind making your diary public? Even if you're just starting weight loss, if you ate what MFP recommended for you you'd lose weight. I might be able to help further if I can see your food log :-) If not I understand
