Not eating won't directly lead to weight gain -- in fact, you may lose weight as you'll temporarily eat fewer calories than you burn. The problem is that fasting is unsustainable, so any weight-loss benefit will likely be short lived and your health will pay the price.
One of the main reasons that undereating can lead to weight gain is because consuming too few calories can cause your resting metabolic rate to slow down. This means you may burn fewer calories throughout the day.
“On a day you don't eat for 24 hours, you're guaranteed to be losing a third or half a pound of non-water weight that's mostly from body fat,” Pilon told Global News. “The truth is intermittent fasting is a way to create slow, steady weight loss.”
When you don't eat often enough in a day, you'll experience a drop in blood sugar, or glucose, the main sugar found in your blood. Low blood sugar can make you feel tired, dizzy, sluggish, shaky and like you may pass out.

Fasting for 72 hours is difficult for most people without any medical assistance. The body will also begin breaking down muscle tissue and can start leading to vitamin and mineral deficiencies and digestive issues. And that is what happens if you eat nothing for 3 days.
It breaks down the proteins in your body so you brain has at least something to run on. Muscle mass is the first thing to go — which makes you feel weak and tired, like your body is getting the flu. Next, your bones start to deteriorate, becoming weak and brittle.
Too few calories can hamper your metabolism, sabotaging any goal to lose weight. Although some combinations of macronutrients or types of foods may affect weight loss synergistically, when it comes to dropping pounds, there's no denying that calories matter.
Would you believe that eating less can result in more belly fat? It's true. While intuitively it makes sense that eating fewer calories will lead to a flat stomach, the reality is that because of the effects undereating can have on certain hormones, not eating enough can lead to fat accumulation on your midsection.
However, other studies show that while consuming 1,000 calories a day may result in significant weight loss, most people cannot sustain it and often experience significant weight regain . The reasons include regaining lost muscle mass and increased appetite. Also worth noting is that the human body can adapt.
In general, it is likely that a person could survive between 1 and 2 months without food. As many different factors influence the length of time that the body can last without food, this period will vary among individuals.
It Will Not Lead To Fat Loss
While some people do this diet for the potential health benefits, many are attracted to the fasting for 3 days diet as a way to lose weight. However, as mentioned above most of the weight loss is water weight and not fat loss.
Altogether, it seems possible to survive without food and drink within a time span of 8 to 21 days. If a person is only deprived of food, the survival time may even go up to about two months, although this is influenced by many factors.
Eating one meal a day can increase your blood pressure and cholesterol. This occurred in a group of healthy adults who switched to one meal a day to participate in a study. If you already have concerns in either area, eating just once a day might not be safe. Eating one meal late can cause your blood sugar to spike.
Research suggests that alternate-day fasting is about as effective as a typical low-calorie diet for weight loss. Fasting also affects metabolic processes in the body that may work to decrease inflammation, as well as improve blood sugar regulation and physical stress response.
Some markers include reduction in blood pressure and cholesterol levels, and surprisingly an increase of energy and clarity of thinking. One theory is that hunger initiates a constant stress level that makes us stronger and more resistant to aging.
