Why Diets Fail

Most diets advocate; to lose weight you reduce calories and you will, but, only for a limited time. Reducing calories, drops your nutrients. Your metabolism slows to match the lower incoming calorie and nutrient level.


Your body chooses where to distribute the reduced available nutrients. Your brain gets priority. Your hair, skin and nails can probably function without the best nutrition for a while. These areas gradually lose their sparkle and energy. However, alarm bells will be going off in your brain with a strong message to upload more nutrients. This can make you hungry, tired and grumpy. Weight loss slows down and to maintain weight loss, requires further calorie reduction.


Few people can withstand this, eventually succumbing to their body’s demands for more food.


During WW II, the US Government commissioned a starvation study. The Minnesota Starvation Experiment. 36 male volunteers spent 6 months on 1600 calories per day. They ate mainly potatoes, turnips, bread and macaroni. A high carbohydrate diet.


They became depressed, lost concentration, became preoccupied with food and very distressed. Some ended up hospitalized, yet most weight loss programs use this type of approach to diet.


There is a better way. In the 1970’s, 2 researchers, Blackburn and Bistrian at Harvard Medical School developed a “protein-sparing modified fast” to treat obesity: 650 to 800 calories a day of nothing but fish and meat. Effectively no carbohydrates, making it a low-calorie keto diet. One publication highlighted the average weight loss of 700 people was nearly fifty pounds in four months. The patients felt little hunger. “They loved it,” Bistrian said. “It was an extraordinarily safe way to lose weight.” Sadly they stopped, because they mistakenly thought that low carbohydrate levels were unhealthy.


The difference between these diets is the carbohydrates. High carbohydrate diets with low calories, force your body into starvation mode because the resulting high insulin level prevents the body from accessing fat reserves. But if you become fat adapted, eating higher fats and very low carbohydrates, the body can use stored body fat to replace missing calories.


A successful way to get fat adapted is to severely reduce carbohydrates in your diet. Replacing most carbohydrates with good fats. Carbohydrates are not essential because your liver will make glucose from fat if needed.


I have eaten this way for 3 years. No weighing food or counting calories. I seldom feel hungry. Do I need carbs for exercise and energy? No way. I run, swim, use the gym, or kayak with no shortage of energy. Fat adapted people claim increased energy. My weight is down 11 kgs and blood pressure is back to normal.


Reducing calories does reduce weight, but unless done right, is unlikely to be sustainable.


Seek professional medical advice before any changes, particularly if you are on medication or have any underlying health problems.
