How Long Can We Last Without Food

How long should I stay in Ketosis? Long term, short term, cyclical, seasonal ketogenic diet?

Once you start fasting, you may feel ravenously hungry as your mind is flooded with images of your muscles disintegrating into thin air. This is simply how your mind reacts to the threat of starvation just because it feels like you will lose all your muscle and starve doesnt mean you will.

In fact, Mahatma Gandhi survived for 21 days without food while only taking in sips of water. During times when people had no food or water at all, they were able to survive for 10 to 14 days. However, these are just anecdotes what does the science say?

Many studies have been done during hunger strikes and religious fasts confirming that humans have the capacity to survive even longer than Gandhi did during his fast.

One monk, for example, set out to do a 40 day fast with medical supervision while maintaining his daily activities in the monastery. After 36 days, the medical professionals had to step in due to profound weakness and low blood pressure when standing. Although the monk fasted for 15 days longer than Ghandi, the medical professionals were able to stop the fast in time so that he could recover.

Another study tracked 33 political prisoners who were on hunger strike. The prisoners fasted for 6-24 days before being hospitalized for dehydration due an inadequate intake of fluids and electrolytes . Breaking their fast was described as being uncomplicated.

Why This Doctor Recommends Keto

Would clinical nutritionist Dr. Josh Axe, DNM, DC, CNC, recommend the keto diet? “Absolutely,” he told POPSUGAR. But there is a catch. You can’t do it forever.

A brief refresher, if you don’t already know: the keto diet is a high-fat, moderate-protein, low-carb diet in which you switch your body’s primary energy source from carbohydrates to fat . Up to 80 percent of your calories come from fat we’re not kidding when we say high-fat! That’s what differentiates this diet from something like Paleo or Atkins they’re both low-carb, but with keto, the emphasis is on the fats.

“I don’t think somebody should be on a full ketogenic diet for more than three months,” he said. “What I teach is not that everybody should be on a ketogenic diet the basis of what I teach is traditional Chinese medicine, or TCM but if somebody has the goal of overcoming epilepsy, fighting cancer, overcoming blood sugar issues like diabetes, losing weight, or even some hormonal issues, the ketogenic diet is a great temporary diet.”

“Everybody is different depending on somebody’s genetics, depending on somebody’s health goals or struggles, certain people should be on certain diets,” said Dr. Axe. For the patients he believes need the keto diet for what he calls “a breakthrough” in their health, he likes to limit it to three months.

“The ketogenic diet is a great temporary diet.”

Intermittent Fasting And Cancer

Although there is little to no literature on the effects of 2 or 3 day fasts on muscle loss in humans, many clinical trials are currently being conducted on the effects of 2 or 3 day fasts on cancer patients.

In initial case studies, people who were undergoing chemotherapy voluntarily fasted for anywhere between 48 to 140 hours. Each person reported fewer side effects and improved quality of life regardless of how long they fasted.

This may suggest that fasting for 2 days to a week can have a protective effect on the cells in the body while they are undergoing intense bouts of toxicity.

Other studies in animals have found that fasting was possibly as effective as chemotherapeutic agents in delaying the progression of different tumors and increased the effectiveness of chemotherapeutic drugs against melanoma, glioma, and breast cancer cells. Although this research may not apply to your life, it does suggest that intermittent fasting can help support your body in times of toxic stress.

Final Thoughts On Keto And Weight Loss

There are far too many factors involved in individual weight loss to predict with any certainty how long it will take to shed the pounds. Generally, youll need to adhere to a caloric deficit of around 500 calories per day. At this rate, you should start to see noticeable weight loss after anywhere from 10 to 21 days. Some may meet their weight loss goals sooner, while others may take a bit longer. Keep in mind that water weight is often the first thing the body sheds in the first week when grams of carbs are restricted, as for every 1 gram of carbohydrates that are stored, 3 grams of water are stored with it. Thats why the scale may not give you an accurate portrayal of how much body weight is actually lost. This also means that, when carbohydrates are introduced back into the diet, that water weight will come back with them, which is completely normal and healthy.

Sustainability is a more important factor than short-term weight loss results or timing, however. Although it comes with certain risk factors for those who may be sensitive to fats, the keto diet is a preferred choice for many who feel that it presents a more manageable style of eating.
