Critical Concept: lose weight = calories in < calories out
The critical concept of weight loss is that you must consume less caloric energy than you burn off. To lose weight = calories in < calories out. This oft heard saying continues to be true. So why is this so very difficult? If the answer was easy, most people would not be overweight. This is where the explanation gets quite complex.
Cravings: Hormones will overcome your Willpower
Reduce your caloric intake and all of us will feel hungry and have food cravings. Even without caloric restriction we all usually have sugar cravings. The battle between our willpower and cravings is legendary and is most usually lost, leading us to feel bad, dejected and prevents us from reducing weight. It is best to not solely rely on willpower and motivation for such long-term endeavors such as weight loss.
- burning of body fat for internal body energy and
- satiety from the foods we do eat.
This combination is critical for your success.
Burning of body fat for energy
The body has three energy sources it can burn for fuel. These are:
- Sugars and carbohydrates from eaten food. This is the easiest to digest and the most readily available source of energy. Sugars and carbs, converted to glucose, are quickly digested into immediate body energy
- internal body fat, stored when we previously ate an excess of food. This is the fuel source used when there are no sugars or carbs eaten for the last 8-12 hours. The body has in excess of 100,000 calories of stored body fat, even for those that are lean. This is the alternative fuel source and is always on hand, but only available to burn when there is no sugars or carbs (glucose) available.
- Muscle mass: This is the last resort energy source, when all other food sources are exhausted. The body works hard to preserve this at all costs.
Our Carb-centric Society and Carb Addiction
Logically if you wish to reduce weight you would want to burn body fat as fuel, as less body fat will result in weight loss. There are three main obstacles to burning body fat:
- Sugars and carbs are addictive. Our body is designed to grab these high energy food sources when it can, because it knows they are easily digested and used as fuel. Our hormones do not allow us to turn off this addiction. There is also no internal automatic mechanism to restrict sugar and carb consumption. This is beneficial when sugars and carbs are in short supply, which is almost never. Any excess consumption of sugars and carb will be stored as body fat. Further, when sugars and carbs are readily available, body fat burning is turned off.
- Our society and health organizations promote the consumption of sugars and carbs eaten on a daily basis, often in excess of 300g of carbs each day. Carbs are thought of as healthy and necessary. Much of our social eating and family meals is centered around carbs.
- Mankind has developed ultra-processed carb-based foods that are extremely delicious and therefore addictive. These may come in boxes or in the form of highly sweetened but natural fruit, below-ground vegetables, cereals, grains and legumes. There is almost no food commercial that does not have sugar and carbs prominently featured.
Enter the Ketogenic Diet: Combat your Carb Addiction and Body Fat Storage
There is another way to eat, an alternative that is designed into our human bodies. Sugars and carbs are not necessary for humans to live. The body is very capable in using eaten proteins and fats to produce glucose, or internal body sugar, for fuel. In the absence of carbs the body will also break down body fat into ketones, the alternative energy source for the body. Micro-nutrients can come from above-ground vegetables.
Feeling Full After a Meal: Satiation
If you eat enough meat protein in a meal you will feel satiated and then naturally feel full and stop eating. Meat protein includes red meat, chicken, fish, eggs. This is critical because without enough protein and fat, you will continue to eat, and even over eat, and thus store these extra calories as body fat.
Specific Diet Advice
What diet you choose is up to you. Choose one that is suitable for your lifestyle and one that you can sustain. It will be much easier if it was a low carb diet, but how low is your decision.
Consider Intermittent Fasting
Intermittent fasting is when you extend the time you do not eat and restrict the times you do eat. If you do not eat, you will not consume sugars and carbs, and your body will be forced to use ketones for energy, thus promoting weight loss. This is irregardless of if you eat sugar and carbs or not.
The Role of Exercise
While exercise will make you stronger and fitter, you cannot rely on exercise to reduce weight. In fact, doing long periods of cardio exercise might actually increase your appetite and therefore cravings and caloric intake. It is much easier to rely on dieting to restrict caloric intake.
Why Fructose is so damaging
Fructose is a different sugar than glucose. While Glucose can be readily used by all cells in the body, fructose can only be used by the liver. When eating reasonable fruit and vegetable, this should be ok. What is problematic is that many foods now contain huge amounts of high fructose corn syrup HFCS, which overloads our liver. Blood glucose and H1C tests do not detect fructose, and therefore it is vastly undercounted as a danger.
