Does anyone know if I am holdilg water because of too much sodium wouldnt I still lose fat? I have been cutting and have lost 20lbs @ 2 a week but for the last 3 weeks I have not lost anything weight or body fat %. Even if I am reataining water do to extra sodium should i not eventualy lose more weight do to fat burn?
Too much sodium can cause water retention, yes. However, water retention should not cause an effect on fat loss, and whilst it may mean that you do not see any weight loss, be aware that you can still be losing bodyfat with no change in scale weight.
If you're not making any changes re body mass AND body composition, then take a look at your NUTRITION and/or TRAINING to find the issue and change things up, since it sounds like you have just reached a plateau.
