I've spent about 4 months using MFP, and in that time I've gone from weighing 277 to 222 pounds (55 lbs). I'm 6'1".

Unfortunately, I think I may have done this the bad way. I eat 80-100 grams of protein, 20-35 grams of fat and about 100 grams of carbs everyday. I also exercise frequently (both cardio and strength) But for the past month or so I haven't been taking in more than 800-1200 calories a day. Now I'm afraid I have messed things up- because the scale hasn't moved in about 10 days.

Yes I know, I should have avoided this from the get go, but I didn't. Now, after an open forum post and being referred to this group- I have realized that a RESET is called for. Can someone help me out with a plan? these guys- http://scoobysworkshop.com/calorie-calculator/ say I should be at about 1600 calories a day. How much should i eat during this reset, and how long should it last?

Thanks for the help everyone.

I am 6'0" and 238 and my BMR is over 2100. My TDEE at lightly active is 2900. I think you have miscalculated. My 15% cut is 2465. You might want to revisit those numbers.

@heybales- Thanks for your response. Could you please elaborate on what you mean by 'a reset means you eat at maintenance' I'm really sorry I'm a little overwhelmed by all this, so this question might be silly. Also, what would be the best way to check my BF%?

So TDEE is your maintenance, where you maintain weight, no weight or inches lost or gained. So you would slowly work your way up to that level, expecting water weight increases the first couple weeks.

You usually have to estimate to get that level, as you discovered, can be very high.

And what's interesting is, you were eating more than that previously before you lost weight and started to diet.
In reality, unless you logged your food back then, the only thing you have to compare it to is what you've been eating and logging on the diet. And as you now know, you had no idea that was such a bad low number. So really, you have nothing objective to compare it to.

Use this to get decent BF%, get BMR based on it, use better activity calculator, and goal number, and log your progress.
And to lower TDEE so you don't have to eat as much, lower your exercise.
Besides which, you don't need the exercise for fat and weight loss, just a reasonable deficit. But it helps while doing it so you can eat more. So you may find you can back off the exercise, lower the TDEE and eating goal, and still get better workouts in for body improvements.
Because really, exercise tears down, rest and recovery and repair is what actually builds back up better, if given good nutrition.

@heybales: Thank you so much for the clarification and that's a great tool you shared. Just to recap, should I expect a significant increase in my weight over the next few weeks while i inch my way back up to my TDEE? And is it necesary to go back up to the TDEE, stabalize, and then target the TDEE-20%, or would it be acceptable to target an increase only to the TDEE-20%?

I'm sure every person is different, but I want to make sure I am not shocked and demoralized by the numbers i see between my feet.

Depends on how depleted of glucose stores you've been constantly running on.
500 cal's worth is 1 lb of weight.
Other improvements including blood volume will increase weight too.

I'd say at least work your way up to the recommended TDEG for whatever routine you plan on keeping. If you don't hit the weight loss mentioned and your workouts are not new and causing improvements to hide it, then start increasing to TDEE.
As guy you'll probably just be able to hit that level for a week or two and head back down slowly.

And you'll have to find your valid weigh-in days (morning after rest day eating normal sodium levels not sore from last lifting workout) and measure then too.
Because you'll need to rely on measurements while your body gets a chance to finish making improvements to support the exercise you are doing.
Most will report some inches drop even during the increase while weight remains the same or actually goes up. Some lucky ones do report weight loss while increasing. And they increase until it stops. And discover when they go back down, they get more weight loss than when they were coming up.
