Depending on your lifestyle and when you can manage to stop eating, the best hours for intermittent fasting include the 16/8 or 14/10 fasting periods. Intermittent fasting is hailed by many as the new mantra of weight loss, disease prevention, and reversal of aging.

In a 'fasted' state, which typically starts 10–12 hours after your last meal, the body is depleted of this form of glucose. Then the liver begins to break down stored fat into fatty acids called ketones to use as fuel. This process is known as 'metabolic switching' and is a reason why fasting can lead to weight loss.

If you consistently stay active while following intermittent fasting, you can lose as much as 6-8 pounds per month. This estimation is shockingly high when you consider that all you have to do is not eat for select hours throughout the day.

A 2023 review of research found that the 16/8 method and 16/8 combined with restricting calories were effective strategies for weight control in adults with overweight or obesity. An eating window starting before noon led to greater weight loss than one that began after noon.

Technically speaking, eating or drinking any calories breaks a fast. That means it's generally considered OK to drink black, unsweetened coffee or tea, as well as water.

According to some researchers, fasting for 10–16 hours can cause the body to turn its fat stores into energy, which releases ketones into the bloodstream. This should encourage weight loss. This type of intermittent fasting plan may be a good option for beginners.

The 5:2 diet is based on a principle known as intermittent fasting. This is where you eat normally at certain times and then fast during other times. There are different versions, but the 5:2 diet involves eating a normal, healthy diet for five days every week and 'fasting' on the remaining two days.

It's difficult for some people to stick with intermittent fasting, but these tips may help you maximize your results. Focus on fresh, whole foods—including filling fiber, healthy fats, and protein—instead of processed foods. Make your fasting days your rest days from exercise to avoid feeling fatigued.

Is it better to skip breakfast or dinner in intermittent fasting? ›

“Biologically, this makes sense, as skipping breakfast is known to affect glucose and lipid control, as well as insulin levels,” said co-author Anna Palomar Cros. The research also found that eating dinner after 10pm increased the risk further, while eating about five times a day was linked to lower disease incidence.

As much as IF is filled with benefits, there are mild side effects that can happen during fasting, which do not generally require medical or surgical treatment. Possible side effects can include dizziness, nausea, insomnia, headache, weakness, etc.

Weinandy says that results are usually apparent around the 10-week mark, adding that she sees an average weight loss of seven to 10 pounds over that period through any of the three approaches to intermittent fasting mentioned previously. It might take longer than that since everyone's metabolism works differently.

Put simply, when people practice intermittent fasting without exercising, they are losing weight, but much of it often comes from the muscle in the lean mass. If they are exercising, then that shifts from a loss of muscle mass to a loss fat mass, so that's a large benefit.

That's how long it takes your body to switch from using glucose for energy to using fat for energy. Additionally, it will take your body a while to get used to this new eating schedule. So don't expect results right away. You may need to wait between 2 and 4 weeks to see or feel any results.

While practicing intermittent fasting, your body moves through several phases of the fed-fast cycle, depending on the amount of time that you fast. The four phases include the fed state, early fasting state, fasting state, and long-term fasting state (starvation state).

A good option for beginners, then, is to fast for a set number of hours each day. This option allows you to start with fasting for around 12 hours a day, most of which you will be asleep. After you get more comfortable with 12-hour fasts, you can slowly lengthen the time of the fast.

Alternate-day fasting (ADF) is an intermittent fasting approach. The basic idea is that you fast on one day and then eat what you want the next day. This way you only need to restrict what you eat half of the time. On fasting days, you're allowed to drink as many calorie-free beverages as you like.

The easiest way to do the 12-hour fast is to include the period of sleep in the fasting window. For example, a person could choose to fast between 7 p.m. and 7 a.m. They would need to finish their dinner before 7 p.m. and wait until 7 a.m. to eat breakfast but would be asleep for much of the time in between.
