I had someone ask me about changing caloric intake to shock your metabolism. Example one day your intake would be 1900 another 2300 another 2100 and so on....Has anyone heard of this or do this??? Does it work? Mindy
This is what I am using now and as Namita said it's call the zig-zag method. According to Tom Vesuvo's Burn the Fat, Feed the Muscles (BFFM) it's the best method to lose weight and burn fat. You must have a caloric deficit to loose weight, but you don't want to stay in a large deficit for an extended period of time. By zig-zagging your caloric intake you outsmart your body's starvation response.
The basic zig-zag rotation is:
Low calorie days (15-20% below total daily energy expenditure or TDEE) ex: 1500 3 days
High calorie days (maintenance level) ex: 1900 1 day
For an accelerated fat loss rotation:
Low calorie days (30% below TDEE) ex: 1400 cal 3 days
High calorie days (TDEE) ex: 1900 1 day
To prevent lean body mass loss:
Low caloie days (15-20% below TDEE) 3 days
High calorie days (TDEE) 3 days
So it basically depens on your situation as well as your goals. For more information I highly suggest getting BFFM. You can download the book online but he also has a new hardcover book that it coming out now called the Body Fat Solution. It really has no kimmick, just sound advice. Easy?.....No, but nothing worth getting is easy in life!
Hope this help.
