And so on. But hey eat like a pig and exercise like a Spartan if it makes you happy.

[i]"Rather than increasing total energy expenditure linearly in response to physical activity, individuals tend to adapt metabolically to increased physical activity, muting the expected increase in daily energy throughput"[/i] 

[i]"The human body adapts dynamically to maintain total energy expenditure (TEE) within a narrow physiological range. Rather than increasing with physical activity in a dose-dependent manner, experimental and ecological evidence suggests the hypothesis that TEE is a relatively constrained product of our evolved physiology."[/i] - Constrained Total Energy Expenditure and the Evolutionary Biology of Energy Balance. Exerc Sport Sci Rev. 2015 Jul;43(3):110-6

[i]"TEE adjusted for weight and age or PAL did not differ significantly between developing and industrialized countries, which calls into question the role of energy expenditure in the cause of obesity at the population level."[/i] - Energy expenditure in adults living in developing compared with industrialized countries: a meta-analysis of doubly labeled water studies. Am J Clin Nutr. 2011 Feb;93(2):427-41

[i]"As expected, physical activity level, PAL, was greater among Hadza foragers than among Westerners. Nonetheless, average daily energy expenditure of traditional Hadza foragers was no different than that of Westerners after controlling for body size."[/i] Hunter-gatherer energetics and human obesity. PLoS One. 2012;7(7)

[i]"variation in physical activity within the range engaged in by the US population is not modulating obesity risk. Only reduction in calorie intake will result in weight loss, whether done in isolation or together with increases in exercise."[/i] Physical activity does not influence obesity risk: time to clarify the public health message - International Journal of Epidemiology, Volume 42, Issue 6, 1 December 2013, Pages 1831–1836

[i]"No statistically significant changes were found in energy intake or nonexercise physical activity that could explain the different compensatory responses associated with 30 vs. 60 min of daily aerobic exercise. In conclusion, a similar body fat loss was obtained regardless of exercise dose"[/i] Body fat loss and compensatory mechanisms in response to different doses of aerobic exercise--a randomized controlled trial in overweight sedentary males.
