What and when to eat to reduce insulin

healthy eating, diet, gesture and people concept – close up of m

Here’s a startling truth. I can make you fat. Actually, I can make anybody fat. How? I simply prescribe insulin injections. Giving people extra insulin inevitably leads to weight gain. In type 1 diabetes, when insulin levels are extremely low, patients lose weight no matter how many calories they eat. Give insulin – gain weight. No insulin – lose weight (even to the point of death). The implication is clear. Insulin causes weight gain. Knowing this is crucial, because if insulin causes weight gain, then lowering insulin should help with losing weight. But this very different than just counting calories.

The standard (failed) weight loss advice is to restrict a few calories every day by reducing dietary fat and eating multiple times per day. This does not lower insulin much since dietary fat has little insulin effect and eating frequently constantly stimulates insulin secretion. This ‘caloric reduction as primary’ advice has an astounding failure rate. So, if you have tried calorie restriction to lose weight and failed, you are not alone.

So here’s the situation. ‘Medicine’ tells you that obesity is a caloric balance problem and that you should eat less and move more. ‘Medicine’ tells you to eat a low-fat diet, and to eat six or more times a day. This advice doesn’t work for most people. When it doesn’t work, ‘Medicine’ frequently assumes it’s your fault for not being able to stick with the advice. Our advice was good, ‘Medicine’ tells you. You just didn’t do it right.

Imagine, though we have a classroom of 100 pupils. One fails. It’s likely his fault. Maybe he played too many video games. But if 99 students fail, then it’s not a problem with the students. The problem is with the teacher. In obesity, the problem of rampant obesity means that it is obviously not the fault of the people. The fault lies with the official dietary advice.

Understanding that obesity is as much a hormonal disorder as it is a caloric imbalance (as discussed in our last post) means that we must also focus on the insulin effect rather than just the number of calories to successfully lose weight. Reducing insulin depends mostly upon 2 things:

  1. What you eat
  2. When you eat

We often think and talk about the first problem, but both are equally important in lowering insulin levels.

What to eat

The three different macronutrients stimulate insulin to different degrees. Carbohydrates, particularly refined carbohydrates raise insulin the most. Protein also raises insulin somewhat, but likely doesn’t contribute to chronic hyperinsulinemia. Dietary fat raises neither glucose nor insulin.

Most natural foods contain varying combinations of the three macronutrients and therefore raise insulin to varying degrees. For example, refined carbohydrate-rich foods like cookies have the greatest effect on raising insulin and glucose. Fat-rich foods like salmon have little effect on insulin. This differing ability to stimulate insulin means that foods also differ in their fattening effect. This is only common sense.

The overlap between calories and insulin effect is what causes the confusion between the hormonal (insulin) hypothesis of obesity and the caloric hypothesis of obesity. Many people say that ‘A calorie is a calorie’, which is, of course, true. But that’s not the question I asked. The question is ‘Do all calories equally lead to weight gain’? To which the answer is an emphatic no. Insulin-stimulating foods like glucose are more likely to lead to weight gain than non-insulin stimulating foods like kale, even if you have the same number of calories.

Certain factors increase insulin which encourages weight gain. The most important factors raising insulin are refined carbohydrates and insulin resistance. Fructose, from added sugar and fruits can directly cause fatty liver and insulin resistance. This leads the body to increase insulin secretion to compensate.

Other factors decrease insulin, protecting against weight gain. Acids found in fermented foods (sauerkraut, kimchee) and vinegar can lower the insulin effect of foods. Animal protein causes the secretion of incretin hormones that slows the absorption of foods thus lowering insulin. Thus meat has both pro- and anti- insulin effects. Fibre also has the same effect of slowing absorption and insulin effect.


Thus, the main principles for lowering insulin and losing weight would include the following, as detailed in The Obesity Code.

Rules for ‘What to Eat’

  1. Avoid added sugar – causes insulin resistance and high insulin
  2. Eat less refined grains – High insulin effect
  3. Eat adequate protein
  4. Don’t be afraid of eating natural fats – Low insulin effect
  5. Eat real unprocessed foods – refining increases insulin effects

Funny. That’s precisely the sort of no-nonsense advice your grandmother would have given.

When to eat

The second and equally important part of lowering insulin is understanding the question of ‘when to eat’. All foods, aside from pure fat, can raise insulin, which can lead to obesity. But there is another important contributor to high insulin levels outside of food – insulin resistance. This refers to the situation where normal insulin levels are unable to force the blood glucose into the cells. In response, the body raises insulin in a knee-jerk reaction to ‘overcome’ this resistance, and these high levels can further drive obesity. But how did insulin resistance develop in the first place?

Our body follows the biologic principle of homeostasis. If exposed to any prolonged stimulus, the body quickly develops resistance. A baby can sleep soundly in a crowded restaurant because the noise is constant, and the baby has become noise ‘resistant’. But that same baby, in a quiet house, will wake instantly at the slightest creak of the floorboards. Since it has been quiet, the baby has no ‘resistance’ against noises and thus awakens quickly.

If you listen to loud music constantly, you will become slightly deaf. This ‘resistance’ to loud noises protects the ear from damage. Raising the volume to ‘overcome’ this resistance works but only temporarily. Volume increases and you become progressively more deaf (resistant to loud noise), which leads you to raise the volume again. The solution is not to keep raising the volume, but to shut it off.

Think about the story of the boy who cries wolf. Raising the alarm constantly may work at first but eventually leads to the villagers becoming resistant to the signal. The more the boy cries, the less effect it has. The solution is to stop crying wolf.

Insulin resistance is simply a reaction to too much insulin. The body compensates by raising insulin, but that only makes things worse because higher insulin levels lead to more resistance. This is a vicious cycle.

  • High insulin leads to insulin resistance.
  • Insulin resistance leads to higher insulin.

The end result is higher and higher insulin levels, which drives weight gain and obesity. Therefore, a high insulin level depends on 2 things.

  1. High insulin levels
  2. Persistence of those high levels

Providing extended periods of low insulin levels can prevent the development of insulin resistance. How to provide those low levels? Periods of fasting.

This may sound strange, but this is the way we used to eat. Suppose you eat breakfast at 8 am and dinner at 6 pm. You eat for 10 hours of the day and fast for 14 hours. This happens every single day, and the reason we use the word ‘break-fast’. This is the meal that breaks our fast implying that fasting is simply a part of everyday life. The body spends roughly equal portions of every day in the fed (insulin high, storing fat) and the fasted state (insulin low, burning fat). Because of this nice balance, weight tends to stay stable over time. Up until the 1980s, this was pretty standard practice and obesity was not a big issue.

Somehow, we moved away from this traditional way of eating and now eat constantly. We frequently eat the minute we get out of bed in the morning whether we are hungry or not, believing that eating white bread and jam or whole grain cereal is better than eating nothing at all. We eat throughout the day and don’t stop until it is time for bed. Large surveys show that most Americans eat 6-10 times per day. Now our body spends the majority of time in the fed state, and we wonder why we can’t lose weight.

Eating constantly does not provide the critical period of very low insulin to balance the high insulin periods. Persistently high insulin leads to insulin resistance, which leads only to higher insulin. This is the vicious cycle of weight gain that we must break with fasting.


For the boy who cried wolf, which is the better strategy? Stop crying wolf for a month, and then cry loudly once, or cry wolf constantly, but a little more softly? Similarly, to start burning body fat, you must allow prolonged periods of time of low insulin.

Rules for ‘When to Eat’

  1. Don’t eat all the time (time-restricted eating or intermittent fasting). Stop snacking.
  2. If you want to lose more weight – increase the fasting periods

We often obsess about the foods we should or should not eat, the question of ‘what to eat’. But we often ignore the equally important question of ‘when to eat’. By attacking the insulin problem on both fronts, we have a far higher chance of successfully losing weight.

    I have been eating the keto diet for 2 months now and I have not lost a single pound! I wake up in the morning and have Bulletproof Coffee. Then around noon I will have a keto friendly lunch and dinner around 6 and then not eat again until noon the following day. All of this makes so much sense to me but I just can't figure out why I'm not losing weight? I also have given up cheese thinking I was eating too much cheese but to no avail. Can anyone help out with this? I would greatly appreciate it! I love eating this way and I don't miss my carbs or sugar but I would like to lose some weight... 40 lb to be exact!

    I understand you so well - I have the same issue - low carb (no more than 30g /day), high fat and no results. I truly believe in keto that is why I keep this style of life for the last 6 months now. I do not loose weight though. My husband thinks it is the age :)

    Debbie, you could try increasing your water consumption and delay your lunch an hour or so and have a bigger lunch, then skip dinner. This longer fasting time could kickstart your weight loss. Make sure you have lots of nutrients and good fats in your lunch, and some vinegar on your salad. All the best.
  21. Brenda
    To Debbie & Irina -- patience is the key. I had numerous attempts at LCHF and IF, but never had much success with weight loss. Then I read a comment on a blog by a lady who said she had to eat keto for five months before it started working and now she's losing 2lb a week. That got me searching on youtube, and I found Jason Fung and Butter Bob. Lots of wonderful videos. Change my outlook! So on December 1st I began a ten day fast, and then transitioned into OMAD. I eat for one hour a day, and fast for 23. (Once every week or two I extend my window and loosen my restrictions, and I don't always eat low carb. But I make sure I have a decent fast every day, and don't snack.) The extended daily fast gradually lowers your "base level" of insulin, which allows for a gradual increase in fat burning.

    My results? Apart from the good loss I had with my ten day fast (and I didn't regain) I had a slow start. BUT. Last month I lost 4kg (9 lb). I'm now down a total of 42lb (nearly 20 kg), which is wonderful as previously I just couldn't lose weight.

    When you're insulin resistant, and have been fat for years, your liver is fatty. It takes time, and persistence, to clear that fat out of your liver, but once that happens, your body will become much better at burning fat. Stick with it! It will be a long journey (which is why I sometimes indulge a little -- I'm determined to feel 'non-deprived' so I'll be able to keep going for another hundred pounds!).

  22. Silky
    I normally love your analogies Doc but a group of students failing at their education vs people ACTUALLY losing the weight but gaining it all back or having to reduce their food intake even further to match the lowered BMR from the adaptive process (and as a result feeling lethargic, cold all the time, losing hair and suffering depression and anxiety) wont ever been looked at the same.

    One is immediate and the other takes time to show up.

  23. Don
    I agree with this WOE. I am down 50 lbs,, all bad metabokic markers are reversed amd I feel great. It took a bit of time to adapt but now is normal and more than a year in maintenance! The other thing I don’t do anymore is fast food and especially drive-throughs (except for the odd small cappacino made with heavy cream). Eat Real!! ?
  24. Ray Gelabert
    I agree 100% with you. Too much insulin or insulin resistant is what make most peoples fat. For over 40 years treating diabetics with insulin, I saw that fattening effect of that hormone. It makes sense your recommendation of prolongued fasting and watching what we eat.
  25. John
    Dr Fung you are such good value! Thank you for your article.
  26. TeeDee
    If you read up on Insulin Resistance and Non-Alcoholic Fatty Liver Disease (NAFLD) you will soon learn that fruit is certainly NOT the optimal food in any way, shape or form for humans. It was used by our ancestors (and other animals) for weight gain/fat storage in the fall to carry humans over a long winter of scarcity. We rarely have problems with near starvation in our modern societies.
  27. TeeDee
    I had the same problem and discovered that 30-50gr carb was keeping me from losing (I was happy to be maintaining, but I still had about 50lbs to lose!). Then I started cutting back much more on carbs to a ketogenic level (<20g carbs) and it helped a lot, but still much too slow with weight loss. I cut out all alcohol even though it was zero carb because I figured my liver was still ailing from years of Insulin Resistance. I was never a heavy or regular drinker, but it must have been enough to keep me from losing. That REALLY helped, plus I've cut back to the smallest amount of veg I feel I "need" for variety and taste to less than 10g per day and usually less than that. It did the trick and weight loss is steady at about a pound to pound and a half per week. I eat lots of meat and chicken, so I'm never suffering with a lot of hunger and it never feels like a "diet". I'm 61, so I don't expect to lose as fast as I would have in my 20's or 30's. Experiment and see where it takes you. All the best to you both, Irina and Deb :)

    I would like to know more about the vinegar aspect, and how to incorporate that, and when. Also, how do you increase your fiber if you're staying away from carbs?
  29. Vlad
    I personally gave up on having plants in my diet. When i don't fast (right now am 48 hours in my fast, planning to go until thursday of friday, but will stop early if not well),i eat once a day. And that is only beef burger (i can't afford fancy beef), or fatty pork meat fried in butter, chicken liver, and occasionally eggs and dairy. And am doing just fine.
    Don't know about insulin and such, as i don't know what is defined by too much protein (for me, vegetal protein doesn't exist, it makes me sick only thinking about it).
  30. Jolinda
    LCHF and intermittent fasting are amazing and have helped me and my husband (both 70 + years old) reach levels of health and energy that we thought were gone for good. There is another issue that may be overlooked by some of the participants who have trouble losing weight and feeling good. It could be attributed to a sluggish thyroid. I never see this addressed on this site, but I’d like to know more. -J

    Hi Debbie. I would cut out the BPC in the morning. That will break your fast
  32. Pallen
    As the article above said, if you are eating 3 meals a day, you are not fasting enough. Try to eliminate your am coffee, extend your fast longer each day, aiming for a 20hr fast and 4 hr eating period. When I started doing this the lbs and fat started melting away. Good luck, and hang in there.
  33. TA
    Debbie, cut your carbs down below 20 grams. Fast at least 16 hours with only water with vinegar. Eat more fats and less protein. Remember you still may be losing fat and gaining muscle so start measuring your hips and waist. If you can afford a keto meter from keto mojo measure your ketos at the end of your fast before you eat you will probably be surprised at how high your keto level is

    I have a question around insulin resistance.

    If understand that if you are insulin resistant, that the insulin is not working very well/cells are resistant to it... but wouldn’t that mean that energy can not be stored as fat and prevent weight gain, rather than the opposite?

    I know this is false, but I am struggling to understand how if you are resistant to something how it still works.

  39. Andre
    My understanding is that energy storage comes only when insulin is high. It does not mean that insulin is used to store fat but essentially that it trigger the process of transforming excess glucose in glycogen or fat and storing excess diet fat,

    When glucose is consumed or stored; insulin level goes down. This is when you will start using your stored glucose and eventually your stored fat,

    When you are insulin resistant, you just need more insulin to process the same amount of glucose. This means that your blood glucose level will need to go slightly lower than a normal person before you will reach a lower enough insulin level to trigger your body to start using your energy in storage.

    Hope this will help

    I do not believe eating to much protein makes one fat. There have been several studies out about carnivore and people doing them and their labs are outstanding.

    Nothing is mentioned here about the possible negative effects of intermittent fasting on women. I had no idea about these, started doing IF ( something like 16hrs fasting, 8 hrs eating) and after about 10-14 days started having problems falling asleep and staying asleep. Also my estradiol turned out to be high, although I'm not sure it was the result of IF. In addition, my weight didn't budge in those two weeks of IF. Here's a good article about this: https://www.precisionnutrition.com/intermittent-fasting-women

    Brenda - Thank you SO much for writing what you wrote. I too have been on Keto 2 months and no loss. I've been doing Keto and IF now - OMAD for 4 weeks and NO loss. Deep down I was thinking I"m so insulin resistant and I'm certain I have a fatty liver that it's going to take a long time just to cut through all this excess fat. I only need to lose about 40 lbs but I feel like my adipose fat layer is REALLY dense. Knowing that lady took 5 months to get through it all gave me hope to keep plugging away and not give up so thank you so much for sharing. If I can just lower my 'base level' of insulin just to allow for an increase in fat burning - I too might start to see some results. I wish there were more stories like hers to give others hope and to not give up too soon. Five months is a long time but so worth it in the end if I could drop these 40 lbs. It really is so easy to fast and not count, measure and weigh. And it's FREE! ;)

    Let me add my two cents worth as a 76 year old guy. In the Old Days - long, long ago in the Before Times - people were normally slim. They had COFFEE - plain. They didn't have lattes, cappuccinos or any of the other highly sugared coffee drinks.

    Supermarkets had food - REAL FOOD from farmers. Look around now and supermarkets are 80% junk food - highly fructosed junk food.

    Desserts were a treat - not a daily consumption to ease our pain of living. Just a little ice cream once in awhile. We ate for nutrition - not for comfort. We weren't ADDICTED to sugar.

    Oh, and we moved around more. If you worked in an office you would have to GET UP and WALK up stairs or to the other end of the building to transact business. We didn't have computers where we could send an email and sit and wait for a response.

    So, we didn't need three thousand popular diet fads which changed every other day. We didn't live by the theories of whether high or low insulin caused us to be fat because there were so few "foods" that spiked insulin in those days. We NORMALLY intermittent fasted as we ate breakfast, lunch and supper AND THAT WAS ALL.

  49. Matthew
    Just eat less

    Mainly plant based foods

    Try and move a little each day

    Get your sleep 8 hrs

    To Krisin,
    I had many health problems also, ALL doctors tried to "fix" them one at a time untill I came across one who said "You're a coeliac, stop eating gluten" which I did, but it wasn't easy back then, there wasn't much gluten free food around. However most of my problems went away. Incidentally, I now live in Australia, my brother still in England.
    With respect to your father, my brother, a type 2 diabetic, visited me in Australia, and whilst here he ate what was in the house......guten free food. His insulin dependence, during his stay dropped by a massive 50%. When he went back home, and resumed his "normal" diet, his insulin dependence went back up.
    It is interesting to note that the Coeliac Society here readily admit that their experience confirmes this as frequently the case.
    Perhaps some research in this area might answer your query.
  52. No thanks
    Oh my gosh, this guy really hates MD and allied health colleagues.

    I am a female in my late 30s, with prediabetes (BMI 44, A1c of 5.6). I've been obese my entire life, even literally born overweight at 10 pounds, though mother said she did not have gestational diabetes. I do not take any medications, and am hoping to reverse my insulin resistance with diet, exercise, and fasting.

    Since I started a 16:8 intermittent fasting routine, I've noticed that my random blood glucose checks are higher. I have a glucometer to monitor my blood sugar every now and then. I took an A1c reading before staring the fasting routine a month ago, and it returned 5.6 (where I have been for the last two years). I also did a few days of blood sugar monitoring to get a starting point to compare against. My previous fasting glucose levels upon waking were in the high but not diabetic range (105 to 109), but since I've been fasting, they're exploding! I am now waking up to blood sugar readings of 115-120, which is extremely worrying. More so since in addition to only eating between 12:30pm - 8:30pm, I have also reduced my caloric intake to an average of 1400kcal per day, and dropped a lot of sugar and refined carbs from my diet.

    Worst of all is the nerve pain. I developed nerve damage in one of my fingers from carpal tunnel, which rarely bothers me. But now that finger hurts all the dang time, and I've noticed that when my blood sugar hits around 115, the pain starts (and it is excruciating). The pain generally starts after about 14 hours of fasting, and goes away when I am not in my fasting window.

    In the month since I've started IF and dropped my calories, I have lost 5-6 pounds, but I feel that my blood sugar is now out of control. I even went on a 72 hour fast, consuming absolutely nothing but water with some minerals thrown in for electrolyte balance. Even then, random blood sugar checks showed my glucose at 120.

    I don't know what to think, except that my liver is undertaking gluconeogenesis but my cells are too insulin resistant to handle the glucose. Is it possible that my lower carb, lower caloric intake is signaling to my liver to go ahead and create more glucose to dump out for energy, but without eating, there is no insulin response, so now my liver is just dumping glucose freely, and all of that sugar remains floating around in my body, doing damage? Should I continue my fasting regime (and the resulting nerve pain from the higher glucose levels) with the hope that my body just needs a few more weeks to get the message and increase insulin sensitivity, or am I doing a lot more harm than good by fasting in this particular situation?

    You may want to check in with your doctor. While some people may experience higher fasting blood sugar, nerve pain is not an expected side effect. You can also experiment with eating 2-3 meals a day and focusing on eating keto/low carb meals. When each meal has a greatly reduced impact on your blood sugar compared to standard meals, you can lower blood sugar and insulin while also alleviating side effects that some people experience when fasting.
