Phase One Overview: Beginning a Low Carb Diet
A minimum of two weeks, but you may safely follow it for much longer if you have a lot of excess weight to lose or prefer to lose most of your excess pounds relatively quickly. You'll stay in this phase until you're 15 pounds from goal weight.
Shift your body from burning primarily carbs to burning primarily fat, kick-starting weight loss.
Significantly drop your daily Net Carb intake to an average of 20 grams (no less than 18 and no more than 22) of Net Carbs, the level at which almost anyone begins to burn primarily fat.
