what about
calorie is calorie=if it fits your macro (IIFYM)

well thats better, but can be misinterpreted imo.
example:
all protein from protein powder
all carbs from sugar
all fats fom cookies and icecream
ppl can say what the hell they want, but carbs and esp sugars have extremely different effects than a low carb diet, one example,and very important example being the insulin reaction and the bloodsugar reaction,with the followup reaction from the brain and the hunger hormones.
one just needs to look at a bloodsugar graphic which shows what kind of effect eating sugars has on the bloodsugar and insulin release.then they can compare that to complex carbs,whch are nothing else but chained simple sugars, and then compare that to low carb.
and can try to add or reduce protein and then see what happens to the graph, and check if they think fatloss for example being possible at what respective insulin levels.
or even more simple, go to a jacked guy, a bulker and a shredded one and ask them about their diets.
