A lot more causes water retention and high blood pressure than sodium intake. If you are not hypertensive/pre hypertensive or a few weeks out from competition, and you exercise and drink adequate water, then there is no need to restrict sodium. Although, I agree excessive salt is not good.
Define a "bad fat" or "good fat". Trans fats and hydrogenated oils are terrible for you - agreed. The FDA also claims that unsaturated fats are good fats...but we know how unhealthy polyunsaturated fats are - soy bean oil, corn oil, etc. Further, most saturated fats from animals are converted in mono-unsaturated fats, and do not have a bad effect. And, the saturated "scare" is an unsubstantiated hype based on poor science that was recognized as poor science 50 years ago, but still some how made it into the FDA and medicine.
n=1 on the fasted cardio means little except "it works for me". I'm not trying to insult, but rather educate everyone who is reading this thread.
We know a few things, first of all, the amount of calories burned during training is only part of the fat loss equation. Its the amount of calories burned following the training that is also important. Here's what the research shows:
At moderate intensities, fed cardio increases performance, without affecting fat oxidation during exercise, and results in a greater caloric expenditure during the following 24 hours.
Fed cardio spares liver glycogen, which is an important for anticatabolism during hypocaloric consumption (i.e.: eating to drop body fat).
You are right, the majority of people in the gym are not 4% or near competition, and that is why HIIT training is superior for reducing body fat.
Anecdotal evidence: we can look at the physiques of athletes who perform HIIT training: sprinters, football players, etc.
Empirical evidence: HIIT training causes a perturbation in the homeostatic (normal) state of the internal environment (body). HIIT results in the generation of acid, lactate, and the rapid utilization of fuels. The result is two fold:
First, it requires energy to bring the body back to homeostasis. This energy is expended in balancing pH, metabolizing lactate, rebuilding ATP, and replenishing fuels.
Second, the nature of the exercise results in adaptations that promote nutrient partitioning (i.e.: oxidation of fats for resting energy expenditure, carbs to be stored as glycogen, protein synthesis). Next, cellular changes occur. Enzymes responsible for CHO and Fat burning are increased in the muscle cell. This means the athlete can burn more fat as fuel per unit time that someone who is doing low intensity fasted cardio.
I am a nutritionist, am finishing a PhD in exercise physiology, I have competed, and I have prepped several bodybuilders/fitness models for competition, currently am a collegiate bodybuilding team coach, and have also worked with many athletes at various levels from amatuer to pro.
