How To Do A 48
In theory, a 48-hour fast is simple you merely give yourself a full, two-day break from eating. One common method is to stop after dinner on the first day and begin eating again at dinnertime on the third.
Contrary to popular belief, you can still drink zero-calorie fluids, such as water, black coffee, and tea, during the fasting period.
Its vital to drink plenty of fluids to prevent dehydration, which is one of the major potential complications of longer fasts .
Afterward, its important to gradually reintroduce food. That way, you avoid overstimulating your gut, which may lead to bloating, nausea, and diarrhea .
Your first meal post-fast should be a light snack, such as a handful or two of almonds. This would be followed by a small meal one or two hours later.
On non-fasting days, you would maintain your usual eating pattern, making sure to refrain from overindulging in higher-calorie foods.
Its most common to do a 48-hour fast 12 times per month as opposed to once or twice per week, as required by other fasting methods. Appropriately spacing out your 48-hour fasts may offer greater health benefits .
As 48-hour fasting is not advisable for everyone, you should try shorter fasts, such as the 16:8 or alternate-day methods, before doing a 2-day session. This will help you understand how your body responds to a lack of food.
Although the health benefits of intermittent fasting are well documented, specific research on 48-hour fasting is limited.
Intermittent Fasting For Healthy Weight Loss
As weve said, not all weight loss is the same. Its essential to make sure youre losing weight in a healthy way. Can intermittent fasting help with healthy weight loss?
Here, the data are conflicting.
On one hand, intermittent fasting can help improve metabolic health by reducing blood sugar and blood pressure while also improving blood lipid levels.4
On the other hand, two trials suggested that intermittent fasting may not lead to greater weight loss than usual care, or even worse may lead to greater loss of lean muscle mass than usual care or continuous calorie restriction.5
A healthy weight loss intervention also should be relatively easy to comply with and maintain long-term. Fortunately, intermittent fasting may fit that criteria.
One study reported that working adults found time-restricted eating with an eight-hour eating window easy to comply with and maintain for three months.6
That fits with frequent clinical experience suggesting many people easily adapt to time-restricted eating, especially when they follow a low-carb or high-protein diet that helps improve satiety and reduce appetite.7
So, in terms of convenience and ease in your approach to healthy weight loss, intermittent fasting seems to be a winner.
Loss Of Lean Body Mass
In one study, scientists proved that it’s possible to destroy as much as 13 pounds of lean body mass during a 21-day water fast.
Now, maybe you’re the kind of person who doesn’t really care about how much muscle mass they lose during a water fast.
Maybe you just want to get rid of that annoying body fat as quickly as possible, and you’re willing to sacrifice some lean body mass as you do that.
But even if that’s you, you should know that the single most important muscle in your body that can suffer because of this is your heart.
And while a short water fast isn’t likely to cause any serious damage your heart, I’m telling you about this stuff to make sure you always stay on the safe side with fasting.
But still. If you ask me, losing even a single pound of muscle mass mass as you go after a quick drop of that number on your scale isn’t really worth it.
Especially since science has already discovered a better and more effective way of fasting.

What Can You Eat On A Ketogenic Diet
There are myriad options, but the key is to keep your carbs low and your fat intake high.
Heres a basic idea:
Include things like meat, fish, poultry, eggs, leafy greens, other non-starchy vegetables, berries, nuts, cheeses, avocados, coconut oil, olive oil, and butter.
Thats not a complete list obviously, but that should give you quite a few options to consider.
Ive also created a really thorough list of simple and easy ketogenic food options, so if youre thinking about trying low-carb check that out as well!
By the way, youll probably need to increase your salt intake on keto as well, because once your insulin level drops youll be peeing out more salt than before.
How Fast Will You Lose Weight
You may lose 510 pounds of weight sometimes more in the first week of a diet plan and then lose weight consistently after that. The first week is usually a loss of both body fat and water weight.
If youre new to dieting, weight loss may happen more quickly. The more weight you have to lose, the faster youll lose it.
Unless your doctor suggests otherwise, losing 12 pounds per week is usually a safe amount. If youre trying to lose weight faster than that, speak to your doctor about a safe level of calorie reduction.
Aside from weight loss, a low carb diet can improve your health in a few ways, though the long-term effects are not yet known:
- blood sugar levels tend to significantly decrease on low carb diets
- triglycerides tend to go down
- LDL cholesterol goes down (
). Ultimately, you may find a more balanced diet that includes complex carbohydrates is more sustainable.
Significant weight can be lost on a low carb or low calorie diet, but the speed depends on the individual.
General weight loss can improve certain markers of health, such as blood sugar and cholesterol levels.

Benefits Of A Whole Food Diet
In a 2014 analysis by Yale University, they concluded that a diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention.
A diet rich in fruit and vegetables or other high-fiber foods like whole grains and nuts is really important in maintaining good long-term health and preventing health problems like diabetes and cancers. These kinds of foods also help our bodies to cope and control the effects of inflammation.
In fact, one review from 2019 stated that diets high in plant foods could potentially prevent several million premature deaths each year if adopted globally. This is a big endorsement for a whole food diet.
Remind Me Again: What Is Intermittent Fasting Exactly
Essentially, intermittent fasting is a type of eating plan that involves periods of fastingduring which you can consume only water, coffee, and teaand eatingwhen you can generally eat what you like. Such freedom to choose your own chow is one of the many reasons the diet’s racked up so many fans, including stars like Vanessa Hudgens and Halle Berry.
And in a world where many of the top trending diets involve a lot of, well, math, IF stands outs for being fairly simple to understand. It doesnt require counting calories, macros, or measuring ketones. You can eat most anything you want between a specific window of time, although most programs recommend eating healthfully when you do eat,” Sonya Angelone, RD, a spokeswoman for the Academy of Nutrition and Dietetics, previously told Women’s Health.

So Does It Matter How Long You Fast
Interestingly, the researchers report there are no differences between the two fasting groups in terms of weight loss or any other health markers. Without major differences, the UIC study suggests giving yourself a larger window to eat in may be a more convenient option.
Its also telling that there was no added weight loss benefit for people who sustained a longer fast until we have further studies that directly compare the two diets or seek to study the optimal time for fasting, these results suggest that the 6-hour fast might make sense for most people who want to pursue a daily fasting diet.
Fortunately, researchers also find no serious health problems or complaints among the study participants. Although mild adverse events such as dizziness and headaches were reported by some, these were limited primarily to the beginning of the study.
The study is published in the journal Cell Metabolism.
What Can You Eat On The 1: 8 Diet

Make sure to eat a balanced diet.
Tom said, Many people fail the 16:8 diet by packing in too many calories into the 8 hour period, often trying to get some in before the 8 hours ends. You should still be following a strict diet with a complete nutritional breakdown, to ensure you are consuming a targeted number of calories, not to mention macro nutrients and ensuring youre not consuming too much sugar.

The Truth About Fasting
The bottom line: Nutrition experts agree that fasting is a potentially dangerous, and not particularly effective, way to lose weight.
Instead of a fast, opt for a healthy eating plan that you can stick with long-term Healthy diets provide a minimum of 1,200 calories and include a variety of fruits, vegetables, whole grains, low-fat dairy, lean protein, and healthy fats, along with regular physical activity.
If you are not convinced and want to go on a fast, be sure to consult your physician first.

Cut Way Back On Carbs
Start by eliminating foods high in carbs: sweets, bread, pasta, fruit, and similar foods. Going low carb can significantly speed up weight loss, for several reasons.
First, according to high-quality research, very-low-carb diets also known as keto diets reduce hunger.8This allows you to eat less and lose weight quickly without deliberately restricting calories and without feeling hungry or deprived.9
Several studies have shown that low-carb eating is more effective than other diets for losing fat quickly.10
This impressive fat loss may be partly due to the drop in insulin levels that occur during keto eating. When insulin levels are low, your body is primed to burn rather than store fat.11
Finally, some research suggests that continuing to eat low carb to maintain your new weight may help keep your metabolic rate up, increasing the likelihood that youll keep the weight off.12
How many carbs should you eat to lose weight quickly? Sticking to 20 or fewer grams of net carbs per day may produce the fastest results.13
But instead of counting every carb, you can simply choose foods from our ketogenic diet foods list below and avoid any foods that arent on it.
Note: Be sure to read our tips to avoid or minimize symptoms of the keto flubefore going low carb.

How Does Intermittent Fasting Work
There are several different ways to do intermittent fasting, but they are all based on choosing regular time periods to eat and fast. For instance, you might try eating only during an eight-hour period each day and fast for the remainder. Or you might choose to eat only one meal a day two days a week. There are many different intermittent fasting schedules.
Mattson says that after hours without food, the body exhausts its sugar stores and starts burning fat. He refers to this as metabolic switching.
Intermittent fasting contrasts with the normal eating pattern for most Americans, who eat throughout their waking hours, Mattson says. If someone is eating three meals a day, plus snacks, and theyre not exercising, then every time they eat, theyre running on those calories and not burning their fat stores.
Intermittent fasting works by prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat.

/6types Of Dry Fasting
Dry fasting can be easily done with intermittent fasting, alternate-day fasting, eat-stop-eat or periodic fasting. Generally, dry fasting is of two types- soft dry fast and hard dry fast.
Soft dry fast: In soft dry fast, dieters are allowed to use water to brush their teeth, take a shower and wash their faces.
Hard dry fast: In this type of fasting, dieters are not allowed to come in contact with water at all.
What I Ate And How I Exercised While Doing Intermittent Fasting
Limiting my eating to an eight-hour period of the day seemed reasonable. If I exercised in the morning, my first meal would be an early but large lunch at around 11:30 a.m. By 3 p.m., if I was hungry, I could have a snack. At 7 p.m., I would eat a reasonable-size dinner. No snacking after that.
My first thought was that there was no way I would be able to skip breakfast and still work out. My mind was telling me that I would be hungry. The first few days that I tried it, as I would warm up for my workout, I would have visions of chicken with broccoli from a nearby Chinese restaurant in my head. But once I got into my workout, a funny thing would happen. I would completely forget about being hungry. My body would stabilize and water would be enough to keep me moving.
But by the time I got home from the gym, I was starving. Early on, I decided that was going to be my biggest meal of the day. Sometimes it was a lean shoulder steak with a sweet potato. Other times, I would eat an entire chicken along with two cups of broccoli, and the sweetest bottle of Gatorade I ever had. Or occasionally, I would make a taco bowl out of seasoned ground turkey, cheddar cheese, and tomatoes, or a stir-fry with beef and a variety of peppers. It turned out that my calorie intake and lunch would be anywhere from 800 to 1,000 calories, though this part was not an exact science.
