YES! According to the book, Wheat Belly, Genetically-Modified Foods make you fat. While you are not consuming grains while on Ideal Protein, the cow or chicken that you are grilling did!
"Over the past 50 years, wheat has been genetically altered to the point where it is genetically nearly unrecognizable as wheat — but it's still called wheat. Consuming "modern wheat" can turn you into a metabolic mess. Obesity, appetite stimulation, arthritis, faster aging, bone damage, and weak immunity have all been linked to increased consumption of wheat. Some food companies are doing to us what the tobacco companies did: They are ignoring the health facts about their products." Resource: http://www.wheatbellybook.com/wheatbellybook/makingfat
According to the AAEM (American Academy of Environmental Medicine), “Animal studies indicate serious health risks associated with GM food,” including reproductive problems, compromised immunity, accelerated aging, blood sugar imbalances and harm to major organs.
The solution is to BUY ORGANIC. While organic foods are more expensive, the protection from weight gain and assaults to your health is proven. Saving money on groceries by purchasing "sale" or "cheaper" food items can have a "rebound" effect and can cancel out the gains that you make on a weight-reduction diet.
