The GM Diet

The GM Diet or the General Motors Diet is a diet that was supposedly developed by GM for its employees.  The diet is intended to help GM employees to feel healthier and to lose weight.   This is no evidence to confirm that GM is actually behind this diet, it has also been referred to as the 'cabbage soup diet' and the 'sacred heart diet'.

How does it work?  

The principle of the GM diet is that of a negative calorie diet. What this means is that it takes more calories for the foods that you eat to be digested that the number of calories that these foods contain.  

The General Motors Diet is a seven day eating regimen that is also a detox plan.  It is centered around fruits and vegetables and six to eight glasses of water per day.  No alcohol is permitted for the entire seven days.

Day 1:  Eat all the fruit that you want except bananas.
Day 2:  Eat all the vegetables (cooked or raw) that you want.  
Day 3:  Combine veggies and fruits but no bananas or potatoes.
Day 4:  Bananas, bananas, and bananas!  Eat 8 bananas with at least 3 glasses of milk.  Today is also 'Special Soup' day.  Eat this soup anytime you want today and each remaining day.
Day 5:  Lean beef and tomatoes with lots of water.  You can have two ten oz. portions of  lean beef or hamburger with tomatoes.  Drink plenty of water to flush the uric acid from the beef, try to drink at least a gallon of water on day 5.
Day 6:  Lean beef and protein and veggies with no limit on how much you can eat.
Day 7:  All the vegetables, brown rice, and fruit juices that you want.  Give your juicer a work out on day seven.

Day 8:  If you have not reached your desired weight by day seven, you can repeat this diet again and again until you reach your goal weight,

Does this diet work?

Yes.  When you combine a negative calorie diet and a detox diet, you have the ingredients for weight weight loss and significant weight loss..  This fast weight loss is what makes this diet popular.

The GM Diet is a joke and you are the brunt of the joke should you try this diet.  For starters, any short term diet does more harm than good.  A short term diet puts your body on a roller coaster ride that ends up back where you started and usually with a few added pounds.  In addition, the GM diet lacks fish, dairy and whole grains which contain essential nutrients.  Any short term diet ends and then the weight comes back, even worse, is that it can develop a mental association of short term and diet.  A real diet is long term (actually for life) and is sustainable, the GM diet is not sustainable.

In addition, it causes dehydration and puts your body into a starvation mode.  This starvation mode means that your body holds onto fat for dear life and slows your metabolism-the basis for a weight gain disaster when you stop.

The benefit of a short term weight loss is fleeting and the health risks make this diet a bad choice.  I give the General Motors diet two thumbs down!
