Overweight Dogs Part 2



The majority of dogs get fat from eating high glycemic carbs, not from eating protein and fat.


The reason why there are so many overweight dogs is directly related to the high carbohydrate content in dog foods, and particularly the high glycemic rating of those carbohydrates. For instance, baked white potatoes and sweet potatoes that are widely used in dog food have a glycemic index that is higher than white sugar.


Eating fat chemically triggers a feeling of being satiated or full, while eating highly processed, high glycemic carbs, like processed grains and potatoes has the opposite effect, and chemically triggers the desire to eat more.


Mother Nature has designed dogs to thrive on a diet of meat and fat. These directions are encoded in the dogs Mitochondrial DNA and passed to the next generation through the females DNA only. This extraordinary step of discarding the male Mitochondrial DNA to provide extra insurance that the diet will remain basically unchanged over tens of thousands of years reveals the strong emphasis Mother Nature puts on maintaining the appropriate food source (meat and fat) to convert into energy pathways and cellular energy to maintain long term health and survival of the species.


Has anyone seen a fat wolf?
Are there significant percentages of wolves, coyotes, jackals, or dingos in their respective packs that are overweight as a result of eating their species appropriate diet, which is predominantly protein and fat? Is there even one? Probably not.

There are two forms of DNA - Nuclear and Mitochondrial (It's very important to have a basic understanding of the huge difference between them).

Nuclear DNA determines the size, shape, physical attributes and personality in dogs, and can be manipulated fairly easily so that over a relatively short period of time new breeds of dogs can be developed that look very different from each other, and very different from their original dog ancestors

However, the new breeds, along with every other dog on the planet, have inherited Mitochondrial DNA, which determines the preferred source of energy, (the diet), and the energy pathways to transfer that energy into building the body and providing power to the cells, that has remained essentially constant for many tens of thousands of years and it has not changed simply because dogs have been "domesticated".



Embedded in the Mitochondrial DNA of every wolf, coyote, jackal, dingo, and every domesticated dog as well, is the clear voice of Mother Nature insisting on a diet that is predominantly animal protein and fat.  There is a sign on her desk for those who would ignore Her that reads. "Don't Mess With Mother Nature".

Do not confuse what a dog WILL EAT with what it SHOULD EAT.

Will your dog eat a pancake with syrup on it? Probably gobble it up, but that doesn't mean Mother Nature designed your dog to eat it and it doesn't mean that it won't harm your dog. Will your dog eat a dog food with high glycemic potatoes, processed grain, or sweet potatoes in it that have been mixed with flavor enhansors to trick the dog into thinking it's eating meat? Yes - those flavor enhancers are very convincing. In fact one of the reasons that some dogs eat poop is very likely because the synthetic flavor enhansors pass through the system in the fecal matter and trick the dog into thinking the poop is a meat source.

These kinds of high glycemic carbs will ABSOLUTELY harm your dog. Not instantly like a highly toxic poison but over time as they destroy the balance and health of the gut. It's harder to identify the true cause of a problem that develops over time than one to which there is an immediate reaction to like a toxic cleaning agent or poison. High glycemic carbs slowly undermine and destroy the balance of health in the gut and are responsible for causing everything from allergies to hot spots and itchy skin and dozens upon dozens of other health problems that are very hard to trace back to their true origen - which is a faulty diet that contains high glycemic carbs.

Although dogs have no dietary need for carbs, a minimal amount of carbs (as starch) are necessary to bind kibble together when making dog food in kibble form. So it is important to consider the carbs that are used as a binder and to use carbs that are low glycemic carbs.      

If a high quality, low glycemic carb like Cassava is used as a binder then the impact of these carbs on the system can be neutral or even slightly beneficial. I refer to the maximum amount of carbs that can safely be used in kibble as the “Carbohydrate Tipping Point” - the point below which the carb load on the system is small enough to be positive or neutral, but beyond which an increase in the carb load will begin to have a negative impact on the dogs overall health and well being.

If the carbohydrates are low quality, highly processed, and have a high glycemic index like most grains and potatoes used in dog food, the tipping point occurs almost immediately because the high glycemic carbs are detrimental at any level.

Cassava is a low glycemic source carb. used extensively as the primary carbohydrate throughout much of the equatorial regions of the world. Wherever this low glycemic carb makes up 80% of the carbs in the diet there is virtually no adult onset diabetes in the population. Compare that to the epidemic of adult onset diabetes in this country due mainly to diets full of high glycemic, processed carbs and sugar.

We’ve established the premise that dog food with high glycemic carbs and low meat and fat content is actually causing the epidemic of overweight dogs in America and that eating a “Low Fat” diet is not the solution and will only make the matter worse while making your poor dog absolutely miserable.

The ultimate answer to weight loss and maintaining your dogs ideal weight is nothing more than feeding your dog a food that is highly nutritious, high in animal sourced protein, and deviod of high glycemic ingredients.


Making a highly nutritious dog food in kibble form is more expensive, challenging, and rarely done, but it's not impossible and would consist of the following:

  • High protein content (30% to 40%)
  • Over 90% of protein is animal sourced protein
  • Proteins are human grade quality
  • Processing temperatures are kept to a minimum
  • Amino acids are added to replace those lost in processing
  • Fat is a pure Chicken Fat
  • Source of Omega 3 is pure algae sourced (versus questionable fish oils)
  • Cassava as a Low glycemic starch binder
  • Long chain PreBiotics
  • Encapsulated ProBiotics
  • Digestive enzymes
  • NO High Glycemic ingredients
  • No grain, potatoes, sweet potatoes, GMO's
  • No synthetic chemical preservatives (Ethoxyquin, BHA, or GBT)
  • No artificial coloring or flavoring
  • No Anti-biotics
  • No Hormones
