Time-restricted Feeding

Time-restricted eating is a type of diet that focuses on the timing of eating. Instead of limiting the types of food or number of calories that people consume, this diet restricts the amount of time they can spend eating.

What is time-restricted eating?

Time-restricted eating means that a person eats all of their meals and snacks within a particular window of time each day. This timeframe can vary according to the person’s preference and the plan they choose to follow. Typically though, the eating window in time-restricted programs ranges from 6–12 hours a day. Outside of this period, a person consumes no calories. They should, however, drink water or no-calorie beverages to remain hydrated. In some time-restricted diet plans, people may also consume unsweetened coffee or tea with no cream. Time-restricted eating is a type of intermittent fasting. Intermittent fasting refers to any diet that alternates between periods of restricting calories and eating normally. Although time-restricted eating will not work for everyone, those who have their doctor’s approval may find it beneficial. Some recent studies have shown that it can aid weight loss and may lower the risk of metabolic diseases, such as diabetes. Time-restricted eating can help a person to restrict their food intake without having to count calories. It may also be a healthy way to avoid common diet pitfalls, such as late-night snacking. However, people with diabetes or other health issues should speak to their doctor before trying this type of diet.

Does time-restricted eating work?

No single diet plan will work for everyone. While some people are likely to have success with time-restricted eating, others may not benefit from it. It is best to speak to a doctor before trying time-restricted eating, or any other diet. Many of the studies on time-restricted eating have been small or have involved animals rather than people, so large human studies are still necessary. Nonetheless, some recent research shows that time-restricted eating may have the potential to lead to weight loss and health improvement: In a studyTrusted Source designed to mimic obesity in postmenopausal women, mice on a time-restricted feeding schedule lost weight and saw health improvements, unlike the mice that ate around the clock. Another study found that mice that only ate within an 8–9 hour period each day lost weight and had improved metabolic fitness. In one study, researchers allowed obese rats to eat for only 9 hours a day over the 5 weekdays. The young adult rats whose eating was time-restricted gained less weight than those that ate at any time. However, weight gain was the same in both groups of older adult rats. A small study found that time-restricted eating helped people with obesity to lower their calorie intake and lose a small amount of weight. The study limited eating to an 8-hour period and lasted for 12 weeks. Although these studies suggest that time-restricted eating has potential, not all research shows a benefit. A 2017 reviewTrusted Source concluded that intermittent calorie restriction, including time-restricted feeding, offers no significant advantage over limiting calorie intake each day.

Gaining muscle and time-restricted eating

Research has shown that time-restricted eating can work well alongside efforts to build muscle. One study investigated time-restricted eating in young men who followed a set resistance training program for 8 weeks. The men restricted their eating window to 4 hours on the 4 non-workout days each week. The authors concluded that participants who followed the time-restricted eating plan reduced their calorie intake without losing strength. However, time-restricted eating did not result in reductions in body weight or body fat compared to a standard diet. Another study placed resistance-trained men into either a time-restricted eating group or a normal diet group. Those in the time-restricted eating group ate 100 percent of their calorie needs during an 8-hour window each day for 8 weeks. The time-restricted eating led to a decrease in body fat with no reduction in muscle mass.
