The trend of returning to the old master list Paleo diet is not new. Paleo remains a popular weight loss and fitness regimen. Many people have successfully with one of the ten science-proven Paleo steps or algorithms for long term weight loss with minimal guilt. The behavioral sciences point toward a biochemical process including
- energy balance
- consumption habits
- weight maintenance
The human body relies heavily on energy metabolism through calorie-burning as the primary way to process food. We possess nearly every energy required to function. This is why following a diet that deliberately or subtly reduces the amount of energy you consume does not negatively affect the function of your body.
Restrained energy consumption can be much different than the ketogenic diet which involves a reduction in calorie intake to near fat level. This is not the human body and behavior that is responding.
The neurological responses to this often positive experience can be negative and interfere with food control.
In the sleep phase and beyond, metabolism is controlled by neurons and endocrine systems. When energy (calories) are insufficient, metabolic activity surges. Cells that normally sense decreasing energy consumption trigger a signal to energy restriction. This results in lower blood glucose levels than previously normal to compensate for some type of deficit.

This often results in the rapid decline of glucose levels. This disruption is the first step in the metabolic rhythm. The breakdown of glucose occurs in the muscle and fat tissue. These changes produce a surge of endorphins which frequently prevent the reaction. When these supply are long past the point of recovery, the effect of ketosis is far less dramatic. These negative effects linger long after the body has been re-established.
Losing or maintaining weight on a ketogenic diet may negatively impact muscle and energy metabolism. It might even result in a compound imbalance (transient insulin resistance syndrome) where both speed to insulin and insulin resistance worsens. The molecular mechanisms that process glucose affect the ability of the hormone insulin to remain stable throughout the day. This causes the secretion of insulin to fluctuate. This usually resolves itself in the long term. In the meantime, the adrenal glands begin to produce more cortisol, a hormone that assists in the production of testosterone and natural growth hormone.
The application of ketogenic metabolism to athletic performance has been found to increase maximal effort for distance running and to significantly increase endurance over a six week period.
In the long run, consuming less energy might remove the desire for food. In the short term, it can send signals to the brain that go beyond this gradual physiological response. Results in prolonged serotonin release, associated with guilt. There is even a word for this unconscious motivation to avoid food, often called “hungry brain”. It also explains why, after some people with this condition go on a ketogenic diet, they often feel guilty afterward because they were determined to avoid food.
Effects On Weight Gain
Keto diets generally contain no carbs. This is because the body fat is low in carbohydrate content, so the body is unable to make any glycogen or new fat cells. This means all carbohydrates from breads, cakes, crackers, or even ordinary vegetable or meat food, must be strictly eliminated. At a loss for other options, the pressure of elimination also contributes to weight gain.
As stated above, the state of ketosis is temporary. The normal metabolic rhythm returns to an energy balance with the loss of this temporary energy source. Nutrition Myth. The elimination of carbohydrate, insulin sensitivity, and the loss of the endorphins can result in the short term in weight gain. In fact, the decline in total sugars and concentrated carbs already high in the diet can result in weight gain. Individuals on the ketogenic diet have been shown to gain more than seven pounds in the first few weeks of weight loss. Over the next few months, the weight can be lost, but this can be much harder than normal.
Conclusion
Keto is not a recipe for weight loss. The behavioral sciences suggest a gradual lowering of carbohydrate intake.
To ensure total control of energy consumption, the retraining of energy consumption habits and weight maintenance, access to quality foods and relaxed body temperature is required to sustain the physiological response to a ketogenic diet in a long-term way.
