Another possible explanation is that large amounts of processed carbs may induce large swings in blood sugar. As the blood sugar goes down rapidly again (an hour or two after a meal) the body may have to release stress hormones like adrenaline to avoid low sugar. This may accentuate symptoms associated with ADHD. Avoiding processed carbs may stabilize blood sugars and thus avoid this problem.
But Paleo isn’t even really about imitating hunter-gatherers, ancient or modern; it’s about how humans can eat to be healthy and strong. And the research here also backs up the “different strokes for different folks” theory of macros. Different people have hugely varying “optimal” macro ratios, and some lucky people who are relatively healthy can adjust to a huge range of equally acceptable options.
Hey there. I have been on a low carb diet for 5 years now. I lost weight in the beginnng but now I’m simply just maintaining my weight. I have gotten so used to eating this way I will probably always will. I just feel so healthy. My problem is my body has obviously gotten used to the way I eat and I can’t seem to lose any more weight. What do you suggest? I have done an “egg fast” for a week and maybe I lost a pound.
Maryann – Bad as in still too many carb or not enough? While I can’t really make a dietetic recommendation, you can try adjusting 5 grams one way or the other until you get the right number. I started with 20 or less, and have moved up just slightly because my body seems to do better that way. In order to experiment, you really need to track your food with a counter like MyFitnessPal.com. There are many out there, but it’s invaluable information when you are trying to figure these things out.
Thanks for the reply. What’s most confusing is that keto introduced many low-carb but high fat, and therefore, caloric foods. So for instance, before keto, I drank black coffee. On keto I switch to full fat cream and I really like it so I’m still drinking coffee with full fat cream but that means I’m consuming about 5 times the amount of calories I would with my coffee. In ketosis it doesn’t matter because that fat is used up directly as fuel for the day, but if I’m not in ketosis should I switch back to black and start counting calories again?
I like a number of your recipes. I am cooking for my wife who is overweight. Not going into details. Although I have her on a keto diet, I don’t believe it is totally a keto diet. I can say that I am making her some keto recipes and low carb recipes. We were successful in having her lose weight twice, but she fought continuing. This time, she is on it no matter what, after a Dr visit. My wife was always a meat and potatoes girl, meaning she fights vegetables especially. But I am being successful in other ways to see that she eats her fruits and vegetables. Some of your recipes she will not eat. Me, I eat almost anything. So she is a challenge. I want to find or make through recipes foods that are close to what she was use to eating. I am making her tortillas for example. I found an acceptable recipe.
Im on my 5th day of full keto zero carbs. I want to stay with that for a year if I can. I had gastric surgery 10 year ago with no issues but i still have a very small stomach. Im finding that i cant drink my water with out pain because im always full.seems my meat is having a hard tim digesting. Any ideas on what i can do to help the food digest and to get my water in..thanks love your artical
I was on keto for 4 months and felt like CRAP. I ate 1500 cals a day, ate plenty of fat – kept it “clean keto” and could not for the life of me maintain enough energy to workout by the end of the day. It sucked. Yeah, I lost close to 70 lbs, but I felt lousy all the time (and yes, my electrolytes were fine; I took mag and potassium supplements, drank salted bone broth daily – I did it all).

Can you share a few of your low carb recipes with me? I’m trying to lower blood pressure naturally, but at the same time, I don’t want to do the typical DASH diet because , frankly, it has too many grains & carbs in it. The Keto diet has too much fat. & I got tired of the South Beach Diet (which did help me lose 20 pounds a few years ago, I have to admit).
Ketogenic diets usually do cause weight loss and may improve insulin sensitivity in patients with diabetes. In fact when compared to a low-fat diet a ketogenic diet appears to achieve greater long term reductions in body weight. However, the success long term is dependent on your ability to adapt your dietary habits once you start to introduce a more balanced and healthy approach to eating.
I’m 68 yrs. old & was diagnosed as diabetic 6 mos. ago with an A1C of 6.8. My Dr. prescribed Metformin for me, but after seeing the side effects it could cause, I decided to not take it & try Low carbing instead. In 6 weeks, I lost 16 lbs. and lowered my A1C to 6.4. That was enough to convince my Dr. that I could forego the medicine and stick with my diet. 4 mos. later, I’d lost another 14 lbs. and my A1C was down to 5.9! My cholesterol ratio is in the middle of the recommended range, and my triglycerides (I have Fibromyalgia which is said to raise triglycerides) have dropped 100 pts. I’ve lost another 5 lbs. in the last 2 weeks. My Dr. And I are both thrilled, so I highly recommend a Low Carb diet for controlling your glucose level and cholesterol.

I’ll treat my self to a cheese cake occasionally too. It works for me so far. My brother got me on this diet, the first week I told him I don’t know if I can do this and he basically said carry on as you were then and nothing will change and there really is no other way, either you want to lose weight or you don’t and it’s not like you’re suffering or anything so don’t give up. Find a replacement for everything that you miss one by one and soon you will get used to it and you won’t even think about eating any of that junk anymore and if you really do then treat yourself occasionally but just don’t give up.
When you approach your normal body weight, the weight loss will slow. Just remember, a “normal” body weight differs from person to person depending on our genetics and environmental exposures and may not fit what we see in the popular media. The weight loss won’t go on forever. As long as you follow the advice to eat when you are hungry, you will eventually stabilize your weight.
After imagining I'd have a Biggest Loser-type reveal, after two weeks on the diet, I was disappointed to find I'd only lost 1.5kg. But I was pleasantly surprised by the lack of hunger I experienced. For example, if I started the day with bacon and eggs, I wouldn't get hungry again till the afternoon, whereas my typical instant oats breakfast leaves me ravenous by 11am.
Look for ways to scale back that don't feel restrictive: eat one piece of toast at breakfast instead of two. If that's manageable, cut back by another 15 grams and ditch half the bun on your burger at lunch. Ideally, you'll want to get about 30-40 percent of your calories from carbs, says Weinandy. Don't overlook total calories, protein, and fat: all are important to maintain a balanced diet.

  A week and more into the low carb diet, I bumped into the term called ‘Macros’ and everyone over the internet was talking about macros this and macros that. After a bunch of google search I finally found out that macro was a short form of ‘Macronutrients’ and keeping count of such nutrients is really essential as you tend to indulge in a weight loss plan.

As there aren’t yet any studies on stricter low-carb or keto diets for acne at this time, it’s difficult to determine the degree of carb restriction needed to achieve the best results. Similar to losing weight or reducing blood sugar, the necessary carb reduction for potential acne control likely varies from person to person. It’s possible that stricter low-carb diets are more effective.

Carbohydrates have been linked to this skin condition, so cutting down on them may help. And the drop in insulin that a ketogenic diet can trigger may also help stop acne breakouts. (Insulin can cause your body to make other hormones that bring on outbreaks.) Still, more research is needed to determine exactly how much effect, if any, the diet actually has on acne. 

A low-fat diet may be preferable for some individuals while other individuals may do better on a low carbohydrate diet. The fact that I may recommend a Paleo or an Atkins type diet for some people, does not mean that I am against whole grain or potatoes. Although  I recommend everybody to avoid simple refined sugars and junk food, I think complex carbohydrates, starches, and not least fiber can be a part of a healthy diet for many people.
I eat a diet that varies from ketogenic to simply very low carb, and I love it. After a lifetime of being overweight and unfit, I am now, in middle age, in the best shape of my life. I weigh less and wear a smaller size than I did in my teens. I am also stronger and fitter than ever. In addition, my physician was "keep[ing] an eye on" a number of health issues of the type that most people assume are the inevitable result of ageing: Elevated blood lipids; elevated blood pressure; elevated blood sugar. I attribute a great deal of my success to the fact that I was motivated this time much more by health than vanity. They wanted me to go on statins, and I just refused. I applied myself in earnest to a low-carb way of eating, and in the course of my research I learned about ketogenic diets. I normally eat about 75 grams a day of fat; when I am riding regularly, that's often 100 or more; during long-distance rides, 150+.
Joan – Thanks for stopping by! I’ve been playing around with my macros for a while now. I’ve also been reading a bit here and there about carb-up days. It seems to be a hormonal thing that is particularly good for women. I haven’t actually tried it yet because I’m worried it will knock me out of ketosis. But I know eventually I will. As I understand it, it’s very helpful if keto makes you feel tired. From what I’ve read, it’s a good thing to practice, but in the end, the only thing that really matters is how you feel and how your body responds. We are all so different! If it works for you, then I say stick with it. 🙂
Heart attack in April 2019, very little heart damage. Typical:- high cholesterol, high blood pressure, prescribed atorvastatin, 80mg (serious muscles aches and worrying chest pains) ACE and Beta Blockers. Aspirin and clopidogrel. HbA1c reading 43 in July, Started a low carb high fat diet and was doing intermittent fasting for minim 12hrs max 20hrs and my results are that I have lost 5kg in 4weeks. HbA1c 6weeks after starting was 39, waist reduction, blood pressure is lower, I’m Moving easier, got lots more energy, I’m more focused, no gym visits only walking the dog in the morning. If you’re fat, then you’ll be sick, not if, when.. Focus on the basics and keep it as simple as you can. Eat when your hungry, but try and fast for over 12hrs (use your sleeping to fast as much as possible) fasting increases your body’ ability to tune back into to burning fat. But DONT eat carbs until you’ve got your health back (weight is a poor measure of health) How you feel when your moving about is more important than a number. There’s lots of info on the public health collaboration website, also, you tube Aseem Malhotra, very interesting stuff.
The problem is that when your body is used to burning primarily carbohydrates – as is the case with most people are today – your fat stores are not easily available, and they can’t fuel your brain. This results in your constantly having to fill up by eating before, during and after longer exercise sessions. Or even just to fuel your daily activities and avoid “hanger”.
Cut back on ultra-processed foods and drinks – healthy wholegrain carbs are not the enemy, but junk food certainly is, says Professor Collins. "In Australia, one third of our total daily kilojoule intake comes from 'discretionary choices'." Always being prepared with healthy snacks is a great way to stop you from going to the vending machine mid-afternoon.
But Paleo isn’t even really about imitating hunter-gatherers, ancient or modern; it’s about how humans can eat to be healthy and strong. And the research here also backs up the “different strokes for different folks” theory of macros. Different people have hugely varying “optimal” macro ratios, and some lucky people who are relatively healthy can adjust to a huge range of equally acceptable options.
When you eat less than 50 grams of carbs a day, your body eventually runs out of fuel (blood sugar) it can use quickly. This typically takes 3 to 4 days. Then you’ll start to break down protein and fat for energy, which can make you lose weight. This is called ketosis. It's important to note that the ketogenic diet is a short term diet that's focussed on weight loss rather than the pursuit of health benefits. 
Blood levels of triglycerides have emerged as a very important risk factor for cardiovascular disease.  High serum triglyceride level is associated with abnormal lipoprotein metabolism, as well as with other risk factors including obesity, insulin resistance, diabetes mellitus, and lowered levels of HDL cholesterol. It has been shown in a number of studies that carbohydrate restriction lowers triglyceride levels significantly.
Diabetics, especially, type 1 diabetics are at risk of complications if they attempt to follow a ketogenic diet. For this reason diabetics and anyone with a blood sugar management issue should discuss the potential implications with their GP and healthcare team before embarking on such a regime. Similarly anyone with kidney disease or a family history of such should consult their GP. 

Doug. These numbers are not uncommon on a ketogenic diet. Some people respond with a very high LDL-cholesterol and high total cholesterol. However, we don’t know what this means in terms of risk. Although LDL-cholesterol is generally associated with increased risk of cardiovascular disease, we don’t know what it means in this particular metabolic situation. Your LDL particle number is most probably too high as well, although we really can’t tell much about particle size in your situation. However, a TG/HDL-C ratio less than 2 is to your benefit. If you want to lower your LDL-cholesterol you will probably have… Read more »


Maintain a moderate protein intake. A keto diet is not meant to be a very-high-protein diet. We recommend 1.2 to 1.7 grams of protein per kg of reference body weight per day. This means about 100 grams of protein per day if your lean body mass weight is around 70 kilos (155 pounds). Check out our target protein ranges to find out how much protein you should be aiming for each day.
I have been following a fairly strict Keto diet for the last 4 months. 20g total carbs and have lost 17 lbs and feels so much better. Unfortunately, the way of eating has also given me out of control digestion problems, gas, bloating and serious runs. I am going to back off the Keto and add a few more carbs and hope it helps my tummy and that I can still lose a bit more weight. Another 10 would be perfect.
Thank you for writing this post, it’s very helpful! I started low carbing a while back (probably more than a year ago) and ended up backsliding, as can often happen when trying to drastically change your eating habits. On Friday I had my annual physical and my doctor ordered blood work for glucose and insulin because previous results indicate I’m insulin resistant. The results from Friday indicate I still am, so now I’m a little worried and going back to low carb. One phone app (and website) I’ve found to be really helpful is Fat Secret. You can choose exactly which macro nutrients you want to see and it also shows percent of fat, carbs, and protein in a pie chart that I find helps me wrap my head around what I’ve consumed. It also helps that the app and website don’t seem to promote one eating plan over another.

Jill – Low carb has a much looser definition. It’s pretty open to whatever you want to do. You may want to eat a bit more for satiety if nothing else. But no, you don’t HAVE to go as high in fat. Since there is no real outline for low carb eating, you can pretty much adjust it to anything you want. Experiment and see what your body reacts best to. I’ve brought down my fat intake a bit more as well because I found that I was stalling with 80% fat, 15% protein. I do more like 70% fat and 25% protein now. Got my weight loss moving again. So it’s just about what works best for you and your body.
Maryann – Bad as in still too many carb or not enough? While I can’t really make a dietetic recommendation, you can try adjusting 5 grams one way or the other until you get the right number. I started with 20 or less, and have moved up just slightly because my body seems to do better that way. In order to experiment, you really need to track your food with a counter like MyFitnessPal.com. There are many out there, but it’s invaluable information when you are trying to figure these things out.

The symptoms associated with ketosis are often temporary and may relate to dehydration. These may include headache, dry mouth, bad breath, fatigue and nausea. However, it’s worth noting that because the diet restricts carbs it is typically low in dietary fibre which may have a negative impact on gut health including the presence of gut friendly bacteria. 
When your body burns its stores of fat, it can be hard on your kidneys. And starting a ketogenic diet -- or going back to a normal diet afterward -- can be tricky if you’re obese because of other health issues you’re likely to have, like diabetes, a heart condition, or high blood pressure. If you have any of these conditions, make diet changes slowly and only with the guidance of your doctor.
