So I charted using MFP today...

And having had quite a bad and not very healthy day, during which I feel like I ate a lot, and some serious crap, it turns out that a day of over-eating unhealthy crap for me is actually 1300 kcalories. So why the flippity flip do I gain weight so consistently? I'm 5 ft 6 and used to have the metabolism of a horse (which my three oldest children currently exhibit, for now anyway...) If I even attempt to eat what others consider normal I gain 2+ kg a month. In fact since DD3 was born just under 4 years ago I've gained nearly 10 kg, and not by eating all the pies neither! Gah!

Silly question but are you weighing food to check the portions? It can be really easy to under estimate the amounts of food.

[BustleInYourHedgerow]

Hmm, yes to the weighing and portions, eg. portions of butter etc always seem to be my downfall. What about drinks, what are you drinking and have you included them?

Also things like olive oil or other dressings on salads. So many hidden calories!

It may be worth having a blood test to rule out hypothyroidism, if you are eating so little and still gaining weight.

If you are eating o ly 1300 on a bad day you may not be eating enough. Have a look for the 'roadmap' threads on MFP and make sure you are eating over your Basal Metabolic Rate.

I used MFP for 8 weeks. I logged in everyday. Weighed food, recorded my drinks calories, left nothing out. I had 5 days (not together) of overeats. Most days I was under by approx 300 cals.

I am gaining. I lost 3lbs in the first week, then put it back on and more. I now weigh about 7lbs more than my starting weight.
