Alex said: “If someone is looking for fast weight loss then sure, there are ways like this to achieve it, however, there could be many downsides.
“Losing weight that fast, and eating in such a restricted diet makes it very difficult to maintain muscle.
“Which really should be the goal of any diet, because muscle is so metabolically active, therefore you’d want to keep your muscle in order to have a higher metabolic rate. Let alone looking better and being stronger
“Another downside is that the chances of stopping the diet and going back to your old habits and gaining weight could be highly likely.
