Fasting for weight loss: Time-restricted vs. PeriodicIntermittent fasting for weight loss -
each day. The last group was the control group, so did not change their regular eating habits. After the six-month period ended, the researchers tested whether the changes helped people keep weight off. For six more months, the intermittent fasting group expanded their eating window to 10 hours and the calorie counting group ate enough calories to satisfy their energy needs.
By the end of the year, the intermittent fasting group had consumed fewer calories per day, on average, than the control group and lost about 10 more pounds.
The calorie counting group, meanwhile, ate around fewer calories per day than the control group and lost about 12 more pounds. Prior research on intermittent fasting has shown mixed results when it comes to weight loss. A study found that restricting eating to a narrow time window was no better for weight loss than eating throughout the day.
Another study , published in the Journal of the American Heart Association in January, suggested that eating fewer, smaller meals may actually be more effective for weight loss than time-restricted eating.
However, other research has indicated that intermittent fasting could help people with obesity lose weight. In an editorial published alongside Varady's research Monday, two Colorado researchers suggested that intermittent fasting likely only leads to weight loss under certain conditions.
In general, people have more success with weight loss when they receive intensive counseling, said Dr. Adam Gilden, one of the editorial's authors and an associate professor of medicine at the University of Colorado School of Medicine.
However, Varady said the bulk of research has shown that intermittent fasting helps people eat less food, which in turn helps them lose weight. For example, a article suggests it can help decrease the risk of:.
Some evidence suggests that time-restricted fasting may help with managing metabolic conditions. Aligning when a person eats with their internal body clock may help optimize health and reduce the risk of conditions such as diabetes, heart disease, and liver disease.
However, a meta-analysis indicates that intermittent fasting does not influence blood glucose or blood pressure. A article suggests that intermittent fasting, such as fasting, may help increase life span and promote a higher quality of life.
However, the authors note that there are no long-term studies that show any cause and effect for fasting and aging or longevity.
The National Institute on Aging points out that, even after decades of research, scientists still cannot explain why fasting may lengthen life span. As a result, they cannot confirm the long-term safety of this practice. Human studies in the area are limited, and the potential benefits of intermittent fasting for human longevity are not yet known.
As such, more research is necessary. The intermittent fasting plan has some associated risks and side effects. As a result, the plan is not right for everyone. Potential side effects and risks may include :.

The Warrior Diet involves eating very little, usually just a few servings of raw fruit and vegetables, during a hour fasting window, then eating one large meal at night.
The eating window is usually only around 4 hours. This form of fasting may be best for people who have tried other forms of intermittent fasting already. Supporters of the Warrior Diet claim that humans are natural nocturnal eaters and that eating at night allows the body to gain nutrients in line with its circadian rhythms.
During the 4-hour eating phase, people should make sure that they consume plenty of vegetables, proteins, and healthy fats. They should also include some carbohydrates.
Although it is possible to eat some foods during the fasting period, it can be challenging to stick to strict guidelines on when and what to eat in the long term.
Also, some people have trouble eating such a large meal so close to bedtime. There is also a risk that people on this diet will not eat enough nutrients, such as fiber.

Some fasting practices may involve fasting for one day a week, every other day, or two days a week. People should speak with a healthcare professional to ensure they are staying safe when fasting. There are many ways to do intermittent fasting, and there is no single plan that will work for everyone.
Individuals will experience the best results if they try out the various styles to see what suits their lifestyles and preferences.
