Sound familiar?
You are eating next to nothing and slogging away at the gym only to see no change on the scales.
How is this possible?
Well it turns out that we are exceptionally bad at estimating both our calorie intake AND our energy expenditure.
Lichtman et al (1992) discovered that subjects in their study UNDER-ESTIMATED their calorie intake by an average of 47%! Think about that for a second….
You think you are consuming 1,200 calories, yet in reality you are probably consuming somewhere nearing 1,800.
Holy moly!
Not only that but subjects in this study also OVER-REPORTED calorie expenditure by 51%!
“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” (Lichtman et al, 1992)
So, if you are struggling to lose weight, it is most likely because you are not in a calorie deficit, even though you think you are.
So what reasons contribute to this massive imbalance between what we THINK we are eating, and what we are ACTUALLY eating?
