Hi Thea, That’s wonderful that IF has worked for you. Diets, and particularly fasting, can be very triggering for others with a history of an eating disorder. People who have been in remission can relapse. For more about what concerns and problems others have had, there is alot of information out there, and for starters I recommend this thorough article from Psychology Today: https://www.psychologytoday.com/us/blog/hunger-artist/201411/the-fast-diet-fast-route-disordered-eating
Those studies above, in working with small sample sizes, and different types of fasting than recommended here, would lead me to believe that fasting affects men and women differently, and that many of the weight loss benefits associated with intermittent fasting (that affect insulin and glucose responses) work positively for men and negatively for women.
The Mayo Clinic Diet is designed to help you lose up to 6 to 10 pounds (2.7 to 4.5 kilograms) during the initial two-week phase. After that, you transition into the second phase, where you continue to lose 1 to 2 pounds (0.5 to 1 kilogram) a week until you reach your goal weight. By continuing the lifelong habits that you've learned, you can then maintain your goal weight for the rest of your life.

Cortisone as an oral drug is another common issue (e.g. prednisolone). Cortisone may cause weight gain in the long run, especially at higher doses (e.g. more than 5 mg prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
Drink at least 2 liters (0.53 US gal) of water each day. Water has the double effect of both hydrating your body and filling your stomach with a certain volume of a liquid that has zero calories. The Institute of Medicine determined that an adequate intake (AI) for men is roughly 3 liters (0.8 US gal) (about 13 cups) of total beverages a day. The AI for women is 2.2 liters (about 9 cups) of total beverages a day.[12]

It has totally regulated my appetite and normalised my relationship with food. My obsessive thoughts have completely subsided, my black and white thinking around food has gone, and I no longer binge! This is amazing. For the first time in my adult life I feel like I know what it is like to have a normal relatinoship with food. I eat when I eat, a range of healthy whole foods and occasional less healthy foods. In normal amounts. In manageable amounts. And when my meal is over, I stop! Normal for others, a seeming impossibility for me (and, I’m guessing, others with eating disorders).


I believe this is a disservice to those, like me, with a history of eating disorder. It has made experimenting with IF unnecessarily stressful. Despite my worry about what might happen (reading all these baseless cautions), I went ahead and experimented. In my experience, contrary to this “expert advice”, IF has been the most profoundly effective intervention I’ve experienced for my bulemia.

Sleep enough – for most people at least seven hours per night on average – and keep stress under control. Sleep deprivation and stress hormones raise blood sugar levels, slowing ketosis and weight loss a bit. Plus they might make it harder to stick to a keto diet, and resist temptations. So while handling sleep and stress will not get you into ketosis on it’s own, it’s still worth thinking about.

Therefore, following a gluten-free diet will likely change your nutrient intake. Some gluten-free breads and cereals have significantly varied nutrient levels than the products they are replacing. Some gluten-free foods also have higher fat and sugar contents than the gluten-containing food being replaced. It's important to read labels, not only for gluten content but also for overall nutrient levels, salt, calories from fats and calories from sugars.


The benefits above are the most common ones. But there are others that are potentially even more surprising and – at least for some people – life changing. Did you know that a keto diet can help treat high blood pressure, may result in less acne, may help control migraine, might help with certain mental health issues and could have a few other potential benefits?

I was very curious about this, so I asked the opinion of metabolic expert Dr. Deborah Wexler, Director of the Massachusetts General Hospital Diabetes Center and associate professor at Harvard Medical School. Here is what she told me. “There is evidence to suggest that the circadian rhythm fasting approach, where meals are restricted to an eight to 10-hour period of the daytime, is effective,” she confirmed, though generally she recommends that people “use an eating approach that works for them and is sustainable to them.”

Nutrient-dense, good food is certainly the foundation of weight loss. But an adequate amount of vitamin D can be difficult to ingest via food, especially for those who are vegetarian or don’t eat fatty fish (the main dietary source of vitamin D) on a regular basis. In the case of a lack of sun (such as during the darker months of fall and winter), it’s wise to supplement for multiple health reasons – and perhaps even for your weight.
Reduced hunger. Many people experience a marked reduction in hunger on a keto diet. This may be caused by an increased ability of the body to be fueled by its fat stores. Many people feel great when they eat just once or twice a day, and may automatically end up doing a form of intermittent fasting. This saves time and money, while also speeding up weight loss.

Nuts. It’s very easy to eat until the nuts are gone, regardless of how full you are. A tip: According to science, salted nuts are harder to stop eating than unsalted nuts. Salted nuts tempt you to more overeating. Good to know. Another tip: Avoid bringing the entire bag to the couch, preferably choose a small bowl instead. Personally I often eat all the nuts in front of me, whether I’m hungry or not.
I’m 63 years old and I have been following a daily 19 hour protocol called Fast 5, fast5.org for two years. I eat lunch at 3pm and dinner at 7pm close my eating window at 8pm. I’ve lost 43 lbs and kept it off, feel great and I am no longer pre diabetic. I eat what I want and don’t track anything. I belong to a Facebook Intermittent fasting group called Fast Club and would to have you check it out. Fasting is free and it works!

In addition to improving your health, maintaining a weight loss is likely to improve your life in other ways. For example, a study of participants in the National Weight Control RegistryExternal* found that those who had maintained a significant weight loss reported improvements in not only their physical health, but also their energy levels, physical mobility, general mood, and self-confidence.

Another program called the 5:2 Fast Diet involves eating 5 days a week and fasting for the other 2 days, when women can get no more than 500 calories and men no more than 600. That’s a quarter of the amount you likely eat on the days when you don’t fast. Whether you eat those calories in one sitting or spread them across micro-meals throughout the day is up to you.

Over 8–10 mmol/l: It’s normally impossible to get to this level just by eating a keto diet. It means that something is wrong. The most common cause by far is type 1 diabetes, with severe lack of insulin. Symptoms include feeling very sick with nausea, vomiting, abdominal pain and confusion. The possible end result, ketoacidosis, may be fatal and requires immediate medical care. Learn more
Some people feel better supplementing the already active T3 (sometimes prepared from pig thyroid glands), as it can give a stronger effect than the T4 hormone, but its effect is often harder to control. Most health professionals rarely prescribe or offer such T3 treatment, as it appears to lack significant advantages and may pose a risk when doses are high for an extended period of time. However, T3 replacement is popular among some functional medicine practitioners and naturopathic doctors. Regardless, the key is making sure you follow your levels and symptoms to make sure you aren’t over- or under-replacing thyroid hormones.
Some people eat three times a day and occasionally snack in between (note that frequent snacking could mean that you’d benefit from adding fat to your meals, to increase satiety). However, there’s some evidence that frequent snacking isn’t wise when trying to lose weight. Some people only eat once or twice a day and never snack. Whatever works for you. Just eat when you’re hungry.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.

Very low levels of thyroid hormone usually indicate an autoimmune reaction to the thyroid gland itself. This means you’ll have to take thyroid hormone supplements orally, usually the stable form T4 (Levaxin), which your doctor can prescribe for you. Your body will transform this into the active T3 hormone when necessary. The supplement dose should be adjusted so that you reach normal hormone levels (TSH, T3, T4) and sufficiently alleviate symptoms – though a few people may feel best when keeping TSH slightly below normal.
Chronic stress and inadequate sleep may increase levels of stress hormones such as cortisol in your body. This can cause increased hunger and may result in weight gain. If you’re looking to lose weight, you should review possible ways to decrease or better handle excessive stress in your life. Although this often demands substantial changes, it may immediately affect your stress hormone levels, and perhaps your weight.
Figure out how many calories you should eat each day to lose weight. Losing weight isn't all about weight. The more aware you are of the calories in the food you eat, the more easily you'll be able to eat the right amount of food and do the right amount of exercise to drop a couple of pounds. Take your food journal and look up each item individually. Keep a running tally and add up your calorie total for the day.
In addition to improving your health, maintaining a weight loss is likely to improve your life in other ways. For example, a study of participants in the National Weight Control RegistryExternal* found that those who had maintained a significant weight loss reported improvements in not only their physical health, but also their energy levels, physical mobility, general mood, and self-confidence.

A particular diet may be chosen to seek weight loss or weight gain. Changing a subject's dietary intake, or "going on a diet", can change the energy balance and increase or decrease the amount of fat stored by the body. Some foods are specifically recommended, or even altered, for conformity to the requirements of a particular diet. These diets are often recommended in conjunction with exercise. Specific weight loss programs can be harmful to health, while others may be beneficial and can thus be coined as healthy diets. The terms "healthy diet" and "diet for weight management" are often related, as the two promote healthy weight management. Having a healthy diet is a way to prevent health problems, and will provide the body with the right balance of vitamins, minerals, and other nutrients.[4]
