I have been healthy eating for 3 weeks now and was doing well. I need to lose about 6 stone in total. I had lost 11 lbs in the 3 weeks, but this week I have put on 2 lbs for no reason!

I have been exercising 3 times a week and stick to 1600 calories a day. I always watch my fat, sugar, salt and carb intake.

Why oh why have I out on 2lb?

I previously lost 7 stone in 1 year and did not put on weight once during that time. Unfortunately I have now put all the weight back on

I drink 2 litres of water a day and seem to do everything right. I can't tell if its my time of the month because I have the mirena coil fitted.

It could be a million things. It won't be fat though, and that's a good thing. It's probably just water weight. Scales are fine, but they aren't always 100% accurate. In fact they are never 100% accurate.

Just take it easy and keep doing what you're doing and the weight will take care of itself.

The same happened to me after three weeks I put on two pound, I carried on doing the same and was down three the next week. Don't worry about it just don't let it get you down. You're doing great

Tigermad, are you weighing yourself at the same time every day? Because weight fluctuates throughout the day.

Thanks for the replies guys. I will not give up!

I weigh myself in the morning, straight after I have been to the loo to be exact!

I will give you an update at the weekend when I weigh myself again.

My scales must be right because my hubbys weight is ok.

Don't get too upset and obsessed by the scales - there are so many variables to losing weight that a lot of 'experts' recommend only weighing once a month.

You're doing all the right things, just ignore the blip and carry on just as you are.

One thing I did when I hit a plateau was to zig zag my calories - this website gives a zigzag calculator: http://strengthnspeed.tripod.com/Nut.../ZigZagCal.htm (I hope the link is allowance and works.) Zigzagging stops your body getting used to a set number of calories being consumed each day.

Just a quick update. My weight has started to drop again! Yay!

I have now lost nearly a stone, all but half a pound.

I didn't give up and now I am well chuffed.

Well done for not giving up and congratulations on the loss
