"I have a slow metabolism."
"I'm only eating 1200 calories a day and can't lose."
"Abstract
BACKGROUND AND METHODS:
Some obese subjects repeatedly fail to lose weight even though they report restricting their caloric intake to less than 1200 kcal per day. We studied two explanations for this apparent resistance to diet--low total energy expenditure and underreporting of caloric intake--in 224 consecutive obese subjects presenting for treatment. Group 1 consisted of nine women and one man with a history of diet resistance in whom we evaluated total energy expenditure and its main thermogenic components and actual energy intake for 14 days by indirect calorimetry and analysis of body composition. Group 2, subgroups of which served as controls in the various evaluations, consisted of 67 women and 13 men with no history of diet resistance.
RESULTS:
Total energy expenditure and resting metabolic rate in the subjects with diet resistance (group 1) were within 5 percent of the predicted values for body composition, and there was no significant difference between groups 1 and 2 in the thermic effects of food and exercise. Low energy expenditure was thus excluded as a mechanism of self-reported diet resistance. In contrast, the subjects in group 1 underreported their actual food intake by an average (+/- SD) of 47 +/- 16 percent and overreported their physical activity by 51 +/- 75 percent. Although the subjects in group 1 had no distinct psychopathologic characteristics, they perceived a genetic cause for their obesity, used thyroid medication at a high frequency, and described their eating behavior as relatively normal (all P < 0.05 as compared with group 2).
CONCLUSIONS:
The failure of some obese subjects to lose weight while eating a diet they report as low in calories is due to an energy intake substantially higher than reported and an overestimation of physical activity, not to an abnormality in thermogenesis."

yes, if I would walk more to burn more calories, I would loose more weight. when you have damaged your body by smoking as long as I have, it's hard to breath in 93 degree weather much alone do anything else. I had to make changes or else I was looking at a life of self pity and misory. I'm happy with my results today and trying to stay on track.

Those results tell the tale. I worked (online not IRL) with a f/mid 60's/obese/no thyroid slowly change her habits. She started walking at a local lake. She understood her generic synthroid and how she could improve her diet. 3 years ago she was 115+ pounds lighter and walking the 22+ around the lake with some frequency after 18 months of change and improvement. People with low thyroid can find a way or they can continue to use it as an excuse. Either way, we can see the outcome.

47 percent underreporting! wow. Yes, I know that this is often the case - "I barely eat anything!" from people who just can't lose weight who also don't measure or weigh anything.

Great article - I have read that finding before on the under reporting calories and over reporting activity.

this is both encouraging and discouraging. make sure to look at the half full glass, your body is most probably not different, and with the correct adjustments you will loose weight

When you track every day- it's easy to see how a couple days of large surplus can ruin a good month. Or maybe not ruin it- but lessen the losses. Looking back to April- I only lost 4 pounds or something that month even though I lifted daily. It would be easy to say- I barely ate anything- I always ate 1800 calories- and I did- in fact- do that almost every day- but the days I didn't- I ate BIG and it had a lasting effect. When you use this app and it tells you what your average daily intake is amounting to- it's easy to see... I think people forget about the overeating when they are within their RDI 85-90% of the time- but the overeating doesn't forget about YOU. And also- just the little things that add up when you mindlessly eat. I just try to overestimate calories and under report exercise.

I know that when I got my brain injury 20 months ago, I lost muscle mass from being in pain and unable to move. Even walking was too much for me. I gain 40 pounds and got weak - a bad combo. It is very convincing to me that I need to focus on gaining back that muscle and then some. This however is a case of being metabolically challenged. There are people, many, for whom building muscle is not possible. I feel blessed that I'm rebuilding my stamina, vigor and strength, as I recuperate. It's slow, but I'm working on it. Thank you to the muscle builders for encouraging us all to get to the gym. I'm waiting until after the gardening season, but then I'm joining up again and bringing my older husband with me.
