What Foods Can I Eat And What Do I Have To Avoid
This is a huge perk of intermittent fasting: You technically dont have to alter what you eatyou just have to eat within a certain window of time. On an intermittent fasting diet you dont need to avoid any foods, Gans says. However, one should focus on consuming foods that are high in fiber and healthy fats for satiety, such as quinoa, black beans, spinach, strawberries, avocado, and almonds, and of course other nutrient-dense foods for overall health.

At the same time, its a good idea to limit sugary drinks, processed foods, and simple carbs like white bread, advises Cording. Theyre not providing you with much nourishment, she says. You really want to focus on foods that do you a favor.
That said, plenty of people have paired intermittent fasting with another type of diet, like keto. Again, its not a requirement, but doing intermittent fasting while also altering your diet could help you get results faster.
How Can Intermittent Fasting Help With Weight Loss
Intermittent fasting can be effective in reducing body weight in people of every size, according to a report in Nutrition Reviews . Most studies focused on alternate day fasting or whole-day fasting trials, but there is also evidence to support the success of time-restricted eating. As well as weight loss, intermittent fasting can have cardiometabolic benefits for those with obesity, as found in another review in the 2021 Annual Review of Nutrition .
Similar to the way the keto diet helps with weight loss, intermittent fasting can put you into a state called ketosis where you are using ketones as fuel. A study in the journal of Cell Metabolism indicates that in the state of ketosis, the body metabolizes fat and produces ketones, which the body can use as an alternative energy source.
After a meal, you pass through four different metabolic states as your body digests the food, explains Dr Deborah Lee, MD, from Dr Fox Online Pharmacy . These are: the fed state, the post-absorptive state/early fasting state, the late fasting state, and starvation.
Having worked for many years in the U.Ks National Health Service, initially as a GP, and then as Lead Clinician for an integrated Community Sexual Health Service, Dr Deborah Lee now works as a health and medical writer, with an emphasis on womens health. She is a menopause specialist.
Clearly Define The Reason Youre Doing It
Chiropractor Kira C., 29, has been doing intermittent fasting for about three years. She typically fasts once a week, and Kira says she decided to do intermittent fasting knowing it could support her gut health.
Kira points out that intermittent fasting can be tough to stick with if you dont have a reason in mind for following the eating plan. Clearly define the reason that you are doing it, she says. Certain hours get very challenging and you can feel pretty terrible at the moment. Let your ‘big why’ drive you to push through the tough times. For me, that was improving my gut health.

Individual Differences Among Women
Intermittent fasting for women doesnt follow a set of rules that work for everyone. Body shape and composition are a predictor of different biochemical markers among women. The point is: Intermittent fasting will impact different women differently. Each person is unique this fact doesnt stop at gender differences. You are the owner of your body. For this reason, you need to experiment to see what works for you.
Before You Begin Intermittent Fasting
Before you start intermittent fasting, you need to determine if the plan is suitable and safe for you.
If you are diabetic on medication designed to lower your blood sugar, the medicines need to be adjusted to match your eating schedule. As a doctor in clinical nutrition, I would recommend avoiding whole-day fasting plans and talking to your medical doctor to adjust your medication to match your eating and fasting times.
In addition, speak to your health care provider if you are taking medications that must be taken with food.
Finally, the plan might not be suitable for you if:
- You regularly experience low blood sugar
- You are underweight

Heres What Happened When I Tried Time Restricted Feeding
Krista Scott-Dixon, PhD, Precision Nutritions director of curriculum, is a morning person.
I didnt want to give up my big breakfasts, so I chose evening fasting first. she says. I normally trained in the mornings, so this worked for me.
However, she noticed three things about her sleep when fasting in the afternoons and evenings.
First, she was much more tired. Once my battery ran out, I was done. Getting up the stairs to bed was a terrific ordeal, she says.
Second, although shed conk out quickly, she didnt sleep well.
Third, she woke up extremely earlyat a consistent 4am.
Later, she experimented with skipping breakfast and lunch.
At first, that felt like much more of a sacrifice, she says,
Eventually she got to like the efficiency of waking, grabbing a cup of tea, and getting straight to work. And she slept a lot better after a good meal in the evenings.
Bottom line: For any fasting schedule, youll want to experiment, tweak the plan, and do what works for you.

Intermittent Fasting For Women: The Menstrual Cycle
The menstrual cycle has four uterine stages: the proliferative stage, ovulation, the secretory stage and menstruation. Additionally, over these four uterine stages the ovaries are either in a follicular phase or a luteal phase . Because of this constant fluctuation of hormones, intermittent fasting may not be suitable for women at every stage of the reproductive cycle.
A study in the Journal of Endocrinological Investigation indicates that gonadotropins, the hormones responsible for moderating the follicular and luteal phase, can be interrupted by weight loss related factors, causing changes in reproductive functions including anovulation and infertility.
During a typical menstrual cycle, your estrogen levels start to decline the week before the onset of your period, if an egg is not fertilized, explains Dr Kumaran. The decline in estrogen in the body can be stressful and cause a rise in cortisol levels. As such, adding extra stressors to the body, such as intermittent fasting, may be counterproductive. Similarly, during the first three days of your period you may be losing lots of blood, which again can be quite stressful for the body. It is best to wait for the bleeding to reduce in severity, and then intermittent fasting can safely be resumed.
The best way to approach intermittent fasting as a woman is to feel out how you react to fasting at different times during your cycle some times may feel less sustainable than others.
Intuitive Fasting For Women
Women may benefit from an intermittent fasting approach that is known as intuitive fasting.
Intuitive fasting avoids fasting times that are too long and helps you learn which schedule is right for you. Itâs very simple:
- You wait to eat until you are clearly hungry
- You then eat until full
- You wait again until youâre hungry
With time, your body gets used to this way of eating, and youâll notice that you can increase the time between meals without getting too hungry.

How To Intermittent Fast
Whether you’re a man or woman, there are several different ways to try intermittent fasting. Here are some of the most popular ones:
16:8 fasting : Fast for 16 or 14 hours each day, and then eat within an eight or 10-hour window. For example, this may mean you stop eating at 7 PM and start eating at 11 AM the next day. This is the most popular form of intermittent fasting as you are asleep for the majority of the fast, making it more sustainable, says Ayesta and McKinney.
Alternate-day fasting: This is when you alternate days of regular eating with days of fasting or having just one meal with less than 500 calories. While this is one of the most well-researched strategies for weight loss and metabolic health, Ayesta says it can be too restrictive for some women and requires supervision from a dietitian or nutritionist.
5:2 fasting: This version has you fast for two consecutive days a week, and eat normal meals the other five days. Due to its extreme nature, Ayesta says it should only be adopted under the supervision of a health professional.
One meal a day: Here, you only eat one large meal daily, typically in the evening. However, this method can lead to binging episodes, says Ayesta, and should be implemented with caution especially for those who are physically active.
Is It Safe & Healthy For Women Over 40 To Do Intermittent Fasting
Intermittent fasting isnt for everyone, but it has been shown to be safe and tolerable for many. A randomized pilot study looked at the effects of intermittent fasting and weight loss included adults aged 18 to 55.
The researchers measured the safety and tolerability of alternate-day fasting by looking at changes in weight, body composition, lipids, and insulin sensitivity index. The researchers concluded that alternate day fasting is a safe and tolerable approach to weight loss.
As with any eating pattern you are planning on following, consult with your doctor and/or dietitian first.

Rethink Your Diet And Your Bodys Sensitivity To Carbohydrates
Different body types react to calorie consumption differently, gaining weight or not. Based on your body, its important to reconsider carbs in your food intake, and opt for a healthy and balanced diet instead.
Instead of refined sugars and highly-processed foods, make good choices like healthy fats, whole grains, and high protein sources.
You Can Lose Belly Fat With Intermittent Fasting
Intermittent fasting works to shed belly fat by training your body to burn fat for energy more than glucose. This swap happens naturally when you take longer breaks from eating anywhere from 12 hours to an entire day.
Once your body adjusts to this schedule, youll start to see your belly fat and overall weight go down. Plus, youll likely see a real improvement in every measure of your metabolism. That means intermittent fasting can help whether you have high glucose, high insulin, pre-diabetes or type II diabetes, insulin resistance, high triglycerides, or similar issues.

Does Intermittent Fasting Work For Weight Loss
There is evidence to suggest that people lose some weight when intermittent fasting. However, studies show that there is no significant difference between fasting groups and continuous calorie restriction groups. Calorie restriction is a regimen where calories are reduced from what is normal without causing malnutrition.
How Much Should You Eat During Non
When you do eat during IF, you dont have to worry about being super restrictive. Of course, eating like every day is Thanksgiving doesnt make a lot of sense if you are trying to lose weight, whether youre fasting intermittently or not. Instead, focus on eating enough that you dont feel physically hungry between meals.
Some researchers note that people generally dont overeat during the non-fasting hours, especially once it becomes part of a routine. You should always make sure you continue to drink plenty of water, which not only keeps your system hydrated but also helps you feel less hungry.
Before you get started, check with your healthcare practitioner to see if intermittent fasting is a good idea for you. This is especially important if youre severely underweight, taking blood sugar-lowering drugs, or are experiencingadrenal insufficiency. Right now, I know my adrenal health is not where it should be. If I go a long time without eating, my blood sugar drops too low and I can get spacey, shaky and irritable. Thats why, for now, Im holding off on more rigorous fasting than time-restricted eating.

To help you choose the method that fits your lifestyle, heres a breakdown of the pros and cons of each.
Intermittent Fasting And Disordered Eating In Women
Intermittent fasting may disrupt the balance of ghrelin, the hormone that tells you youre hungry, and leptin, the hormone that makes you feel satiated after eating. Disruptions in these hormones may lead to more cravings, increased hunger, and a lack of satiety. While this may become a problem in both men and women, disordered eating, emotional eating, and eating disorders, such as anorexia, bulimia, and binge eating tend to affect women more.
If you have recovered from an eating disorder it is important that you talk with your healthcare provider before starting an intermittent fasting protocol. If you are currently dealing with an eating disorder, we recommend against intermittent fasting.
