No, the NHS under the Tories received real terms budget increases every year but one (in the second year of the Coalition, when NHS spending rose by very slightly less than inflation).

The problem is that, with large sections of the general public living more and more unhealthy lives, the demands on the NHS have been growing even faster than the real-terms budget. Obesity is correlated with a range of serious health problems - diabetes, cardiovascular disease, various cancers - that devour NHS resources, so the real-terms NHS budget would need to grow at a much faster rate than inflation to cope with the continuing deterioration of public health.

Ultimately, this isn't a problem we should have been trying to spend our way out of anyway. The solution to an obesity epidemic shouldn't have been to try and load the consequences onto the NHS; it should have been to take strong preventative measures to head it off well before the point when a quarter of the adult population of England were technically obese (and as many again were overweight).

When Covid hit, we went into lockdown to avoid overwhelming the NHS - where was the obesity equivalent of the Covid lockdowns?
