Hi,
A lower calorie balanced
diet is very effective for weight loss. A
low carb diet causes the body to go into Ketosis whereby the body uses its fat as a source of energy. Also when you are in ketosis your body feels less hungry. This all sounds good except that this can also lead to kidney issues (even failure), osteoporosis, and kidney stones.
Stay balanced and control your calories and you'll lose weight and avoid the side effects.
Good luck.
