Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration. This is because the waste products of fermentation still contain chemical potential energy that can be released by oxidation.
If you use the Neckline Slimmer daily, you will see results. In my personal experience, I believe the Neckline Slimmer to be a great way to obtain a non surgical face lift. The Neckline Slimmer really does work.
Full length barbell deadlift style won't work because knees get in the way when the rump gets down by the floor. In dead lift the rump is high and the shins vertical so the bar clears. Not so with squats, thus the dumbbell solution for safety. The loss is the need to develop balance when the weight is over your neck.
