How to maintain weight ?

When I hit my goal weight I just added 100 calories at a time until I was satisfied I had my TDEE.

As for a flat tummy, it might just be a matter of a little more time but I would recommend lifting weights. I used to work on building chest, back, shoulder, quad and hamstring muscles only and my tummy was the flattest ever then. Today, I'm still happy with my body and my main form of exercise is running.

Congrats on your progress so far. The first thing I would suggest is to give yourself a 10 pound range (what you weigh now + 10 pounds) that you can maintain in. Remember, you do not have to weigh an exact amount every day. Weigh yourself daily, track your calories and most importantly listen to your body. Don't go to bed hungry or you are in for a binge! Let your calories vary according to your exercise demands, stress..... Tighten up when you can, relax when you need to and give yourself a comfortable weight range to live in. The journey should be pleasant or it's not worth taking.

I do a very physical job - ten hour shifts stacking shelves. So don't need any more exercise. Just not sure how to maintain weight. At the moment I'm still losing but that's got to stop. I've lost the weight on my own so have had no guidance and now need advice on how to maintain weight properly. On the odd occassion when my weight has gone up again by a pound or so it freaks me out ! What is the norm for weight fluctuation ?

Simple answer is you eat the right number of calories to stay within a reasonable range of weight either side of your goal weight. +/- 3 or 4lbs would be sensible. Some people's weight jumps around more, some remain relatively steady. I'm sensitive to salty foods and alcohol - both cause rapid weight change (water). On holiday I gained over a pound a day - but only a small amount was actually fat.

If you are still losing you need to eat more - that's it. No mystery really.
Walk up your calories bit by bit until you find the sweet spot. It really is just a numbers game, people make it more complex than it really is.

Why the terror and fear? You know how to lose weight so why would you lose control?

The worst thing you can do if keep freaking out over normal fluctuations, weight is not just fat and rapid changes in weight can only be fat if you are over or under eating by many thousands of calories.

Hi Bullieforme, I lost 25 kg by diet and exercise and went on a four week vacation and only put on 2kg, I ate whatever and whenever I liked. I know if I had been home and near scales I would have dieted as soon as the 1kg went on, but going away for 4 weeks was a blessing, because my weight fluctuations were not noticable - clothes wise and I honestly thought I would have gained at least 4 kg. So give yourself a break from the scales for 4 weeks, eat sensibly and then see what the "damage" is. I guarantee it won't be nearly as bad as you think. Give your metabolism a chance to catch up to your new way of living. Ditch the scales for 4 weeks, I guarantee you wont regret it. This is now living. I can function, exercise and eat like a "normal" person.

For maintaining your weight you have to make two plans one for putting efforts toward reducing extra weight maintaining your weight. And the other is you have to focus on your daily calorie requirement of your body, and choose the correct food for your body. Try some good exercise and do physical activity to burn extra fat. Every one having different body needs so be aware of your own body need. Take the required vitamin. For tightening of your skin you have to follow a best surgery plan for extra loose skin removal.

Just not sure what to do? Also need to find a way of tightening the flabby skin on belly. Advice please?

Will need to find out what your TDEE is and play around that number to see how your body responds.

Getting rid of excess skin, will take time for one.
But I would encourage weight lifting, and maybe still stay in caloric deficit till it shrinks back
