Those are mostly just arguing that exercise isn't a good way to lose weight. No disagreement about that, although to be super nitpicky, "not good" doesn't mean "doesn't work", they just suggest that there is a cap on how much exercise you can do before your body stops burning more calories, so there's an effective limit on that side of the energy equation.

Also, from the second one:

    Long-term maintenance of weight loss requires sustained energy balance at the reduced body weight. This could be attained by coupling low total daily energy intake (TDEI) with low total daily energy expenditure (TDEE; low energy flux), or by pairing high TDEI with high TDEE (high energy flux

That's exactly what I'm arguing above.
