Results will vary for everyone, but once weekly is likely ok. If your cheat days become a habit, reassess your fasting schedule, especially if you find it tempting to cheat at the same time each day, or each week. If you're going to cheat on what you eat, track this as well.
So, can you have a cheat day while intermittent fasting? Yes, absolutely. An occasional cheat day will not hinder your weight-loss progress if you do it right. In fact, it's scientifically proven that intentional cheat days can even enhance your metabolism [1].
It's totally okay to take a break if you need to. Give yourself a day to refocus. Stay on a healthy eating track but allow yourself treats like an awesome protein smoothie or a serving of healthy beef and broccoli and jump back in the next day.
A short-term fast, such as intermittent fasting, or one missed meal shouldn't have a negative impact on overall metabolic rate (metabolism), but prolonged fasting can significantly slow down your metabolism and make weight loss harder in the long run.
In short, it's okay to stop fasting over the weekend — as long as you don't let yourself go. That means you should still make a conscious effort to make good food choices and eat healthier. However, you don't need to worry as much about when you should be eating or not.
Another intermittent fasting plan, known as the 5:2 approach, involves eating regularly five days a week. For the other two days, you limit yourself to one 500–600 calorie meal. An example would be if you chose to eat normally on every day of the week except Mondays and Thursdays, which would be your one-meal days.
Intermittent fasting is safe for many people, but it's not for everyone. Skipping meals may not be the best way to manage your weight if you're pregnant or breast-feeding. If you have kidney stones, gastroesophageal reflux, diabetes or other medical problems, talk with your doctor before starting intermittent fasting.
Also, once you stop following an intermittent-fasting diet, you will very likely gain the weight back. This is a critical consideration, because many people find the diet difficult to follow long-term.
In the case of Intermittent fasting, skipping your dinner is better and easier. You can have your dinner either early or have a heavy snack and can begin your fasting. Research suggests that fasting in the evening and overnight, then eating early in the morning is the better way to follow this diet to lose weight.
This method of intermittent fasting can be repeated as often as you'd like or even done once or twice a week — whatever your personal preference is. Finding the right eating and fasting windows for this method might take a few days to figure out, especially if you're very active or if you wake up hungry for breakfast.
A cheat day causes some large weight increases, but weight because of water, not fat. Depending on what kind of diet you were on, loading up on carbs on a cheat day can increase your weight noticeably. If you were trying to lose fat, you likely were trying to cut carbohydrates out of your diet.
Final thoughts on stopping intermittent fasting
Extreme hunger, excessive weight loss, dehydration, low blood pressure, and weakness can be adverse health effects of fasting. If fasting is impacting your emotions, decreasing your energy levels, or causing extreme hunger, it may be time to stop.
The ideal way to do an intermittent fast after your cheat day is to go slow. You shouldn't expect your body, mind, or your taste buds to return to normal immediately after a day of indulgent meals. It will take time, for sure. In the meantime, try a not-too-extreme fasting schedule, such as 12/12 or 16/8.
Many people scoff at the notion that having just one cheat day per week will ruin their fat-loss efforts, but it absolutely can.
Weekly Fasts
If you choose a fasting window lasting 24 hours or longer, it's recommended to only practice intermittent fasting 1–2 times per week. Fasting more frequently than that could cause muscle loss or other adverse effects.
"Regardless of which type of intermittent fasting you do, excess calories can occur when you go off the plan," said registered dietitian Kristin Kirkpatrick at Cleveland Clinic Wellness. It makes sense: when you have more time to eat, you have more time to snack throughout the day and into the night.
Insulin sensitivity helps in fat loss and protects the body from diseases such as diabetes, high blood pressure, and heart diseases. During the 16-hour fast, your body undergoes a process known as autophagy, a process where the body destroys old or damaged cells in the body.
Yes, you can! Daily 16:8 time-restricted feeding (TRF) is safe to practice as long as you are acquiring the energy and nutrition that you need within your eating window; 8-hours is typically more than enough time to consume your daily energy/nutrition requirements.
When you fast for shorter durations, your body doesn't have enough time to go into ketosis. This means it won't burn stored fat, and there won't be significant weight loss. As one study concluded, a fasting window of 18-19 hours is more effective in terms of weight loss than those between 12-17 hours [11].
This is how much weight you can lose with intermittent fasting. In doing the fast correctly and ensuring that it is aligning with your mind, body and soul–you can expect a good weight loss of anywhere between 2 to 6 kgs a month with excellent inch loss and increase in energy levels and brain function.
The benefits of a 16-hour fasting schedule are the same as a 12-hour fasting. They include weight loss, aid in the cellular repair process, improved sleep, improved digestion, increased mental health and clarity, and reduced insulin resistance.
The same is with intermittent fasting. Experts suggest that a person needs to follow the basic rules for at least 10 weeks to witness some positive results. Following the diet properly for this period of time will help you shed 3 to 5 kilos of weight (depending on your BMR).
Intermittent Fasting isn't about what you eat – it's about WHEN you eat it. You have a 24-hour period to set your eating schedule, giving you lots of flexibility. Whether it's the weekend, a holiday, or vacation, you never have to “go off” your intermittent fasting program.
You should aim to lose about 1% of your body weight a week. The amount of weight lost each week will slowly decrease. At 250 lbs you can expect to lose 2.5 – 3 lbs a week. But once you pass the 200-pound mark, the rate will go down to 1.5 – 2 lbs a week.
