Lose weight the week i eat over my calorie allowance

It seems kind if weird, but a lot of people have bitten plateaus and once they increase their calories a bit, they are able to lose the weight. I would stay where your at and keep at it. Great job!

Could be a sign 1200 is too low to keep your metabolism up. But I've experienced the same thing. I had a terrible weekend food-wise and have already lost weight this week. I wouldn't be surprised if weight you lose one week has less to do with what you did that week than with previous weeks and your body is catching up.

This happens to me all the time. I've been in a deficit (1500-1700 Cals) since January, but occasionally I will have a day where I eat at maintenence about 2100 calories. Usually within a day or two the scale will drop. I don't know if it's just the body saying "okay, we're not starving here, let go of some of this weight now" or what, but it seems to help. If I feel like the weight's not dropping for a long period of time, I actually eat more for a day on purpose now to help the process along. Don't know and don't care if there's scientific evidence to back this up or not, it just seems to be the way my body works.

The rate of digestion and weight loss varies from week to week due to normal body fluctuations such as bowels, water retention, exercise, etc.

You should eat enough to meet all of your nutrients' requirements (carbs, dietary fat, protein, fiber, vitamins, minerals, etc.) and properly fuel your workouts. It is hard for many people to do this on 1200 calories. With only 8 lbs. left to lose, shooting for almost 2 lbs. a week is aggressive.

Here is some information you may find helpful:

As a rule of thumb, the following weekly targets would give a balance between minimizing negative side effects and seeing a reasonable weekly weight loss:

More than 75 lbs. 2 lbs./week
40-75 lbs. 1.5 lbs./week
10-40 lbs. 1 lb./week
Less than 10 lbs. 0.5 lb./week

It could be 1200 is too low for you. Maybe try upping your calories by 200 and see what happens?? I lost more weight when I ate at 1600 than I did 1200.

Think how much you'd have lost at 2000!

The only way you could lose more at 1600 than 1200 is to burn at least 401 more calories per day.

PS for info, I have lost 49lbs with 8lbs left to loose. I know it will be harder to loose the last 8lbs to get to pre-pregnancy weight.
The last 11weeks I've lost 6lbs, so it's roughly 1.8lbs per week which seems normal?

6lbs. in 11 weeks is .55 lbs/week, not 1.8lbs. but nice job!

Regarding losing in the weeks you eat more, it could just be that is when your body would've lost at the original calorie level. It's never even week to week with me. Though there is some adaptive thermogenesis where we do move less at lower intake levels so you could just be moving more during weeks you eat more. Though it'd have to be a lot more, like all day you're being more active without realizing it.
