The alluring promise of intermittent fasting is that altering mealtimes rather than meals themselves may be beneficial. But what are the dos and don’ts of intermittent fasting?
How does intermittent fasting work? One of the most important controls in our dietary pattern, timing, has been dubbed intermittent fasting (IF) as a catch-all word. More accurately, intermittent fasting refers to an eating schedule that lengthens your body’s fasting condition. You can do this by narrowing the “eating window.” Typically, fasters compress their meals into a smaller window during the day by leaving a large gap between their last meal of one day and the first of the next. Fasters often aim for a 16-hour gap between meals and eat within eight hours.
The three widely used methods of intermittent fasting are as follows:
Alternate day fasting: Have a regular, healthy diet one day, and then go without eating or have one small meal the following day. The typical small lunch contains less than 500 calories.
5-day fast: Five days a week, eat normally, and two days a week, fast.
Time-limited daily fasting: Eat normally, but restrict your daily eating window to eight hours. Skip breakfast, for instance, but have lunch at 11 a.m. and dinner at 7 p.m.
Advantages of intermittent fasting
According to recent studies, intermittent fasting for weight loss may provide some short-term benefits. Short-term fasting can result in ketosis, a metabolic state in which the body burns down stored fat for energy when insufficient glucose is available. Ketone-like compounds grow as a result, which can result in weight loss and consuming fewer calories overall. Research suggests that alternate-day fasting is comparable to a standard low-calorie diet for weight loss. Fasting also changes metabolic pathways in the body that may work to minimize inflammation and enhance blood sugar regulation and physical stress response. However, most of this research has been conducted on animals, and the science needs to be clarified.
Is intermittent fasting dangerous?
According to studies, intermittent and time-restricted fasting has not been associated with symptoms like constipation, diarrhea, nausea, irritability, exhaustion, or dizziness. In the past, there was also concern that someone who practiced intermittent fasting would develop an eating disorder. But if you are at risk for an eating disorder, it is best not to take the IF route.
Are there any side effects?
Unpleasant side effects might result from intermittent fasting. These could include nausea, constipation, headaches, lethargy, sleeplessness, irritability, poor attention, and appetite. Most adverse effects disappear after a month. Some people may find it simpler to maintain an intermittent fasting schedule than to track their calories daily. However, others, especially those with hectic or unpredictable schedules, may find it harder to stick to an intermittent fasting plan.
How much weight can you lose?
Intermittent fasting may result in weight loss of 0.55 to 1.65 pounds (0.25-0.75 kg) each week when considering the rate of weight loss. Additionally, people saw a 4-7% decrease in their waist circumference, a sign that they reduced belly fat. These findings suggest that intermittent fasting may be an effective weight loss strategy. However, the advantages of intermittent fasting go far beyond weight loss; it offers a host of benefits for metabolic health and may lower the chance of developing type 2 diabetes and cardiovascular disease. Several factors, such as your sex, age, height, current weight, amount of activity, metabolic health, and whether you want to maintain, lose, or gain weight, determine how many calories you require each day.
