Is it possible to eat too many calories on LCHF?


Is it possible to eat too many calories on LCHF?

The answer to this and other questions – for example, what type of exercise is best on LCHF? And what should you do if you sleep really poorly? – in this week’s Q&A with Dr. Andreas Eenfeldt:

Exercising on LCHF – cardio or weights?

I have just recently started this way of eating and am going to the gym five days a week. I am morbidly obese. I am enjoying the exercise, I will do a mix of boxing, HIIT circuit, PT session and cardio and weights.

I have been told that cardio any more than once a week is no good and has adverse effects. Could you elaborate further on this for me if it is indeed true or is it up to the individual?

For me personally, I feel that the exercise can only benefit me. On a side note, my PT actually supports this way of eating too!


Hi Christine!

I think the exercise and the cardio is likely to benefit you. Just remember that if you’re morbidly obese then diet quality (few carbs) and only eating when hungry are the most important things, at least when it comes to weight loss.

So focus on getting those right first and consider postponing exercise until those earlier habits are simple to maintain. However, if you’re confident you can do everything at once, good for you!

Can I eat too many calories?

Can I eat too many calories? My carbs are under 18 grams per day, my fat is quite high 130g – 250 grams and my protein around 80 grams. My calories are around 2,500… sometimes up to 2,800.

I have 48 kg (105 lbs) to lose. My blood ketones read 0.3 – 0.4 mmol/L in the mornings and in the evening 0.6 – 1.6mmol/L.

I eat no junk or processed foods or sweeteners or sugars. I am aged 59, partially disabled with fibromyalgia, CFS and arthritis. My weight loss is very slow – non-existant.

So looking at the figures – if I’m eating so many calories will I gain weight? I.e. if my body does not require this quantity of calories, what happens to them? Are they turned into body fat or does the body excrete them?

Some low-carb experts say calories do not matter, others experts say they do, Dr. Jason Fung says reduced calories causes the bodies metabolism to reduce hence no gain in reducing calories… However Dr. Eric Westman says calories do matter. I’m very confused – please can you clarify this for me?

Many thanks,

Hi Joules!

If you eat more than you need, then it will slow down or stop weight loss, even on a low-carb diet. The magic trick for effective weight loss on low carb is to eat ONLY when hungry, try not to eat unless you’re hungry, as that will slow weight loss.

Personally, I think counting calories is not very useful, as it’s often misleading and as you can get at least as good results with less effort by eating only when hungry and if necessary add intermittent fasting.

Sleeping very badly


I am really excited, I have lost 8 kg (18 lbs) since September and have ways to go but I feel good! So LCHF is working well for me.

However, I have recently had a lot of trouble sleeping. I wake up a lot and get up way too early. I do exercise during the morning hours, I stop drinking coffee around midday and try to get to bed at regular hours. I am getting to the point where my cravings for starch and sugar is coming back and so far I have resisted… Any suggestions? I would appreciate it!


If you’re in deep ketosis and get so energetic that you have trouble sleeping it could be good to reduce the ketosis a bit. You could eat more protein, and possibly add just a little bit of unrefined carbs like more veggies, nuts, and perhaps some root vegetables.

Otherwise, just regular advice for sleeping problems, easy to find online via Google.

    I think the sleep issues is not being addressed well. I'm not the only one who can't sleep on this plan. The hunger and inability to sleep is a recipe for failure and saying "Google it" is an insult. Lack of sleep also seems to cause the body to hold onto the excess fat. So. Why can't I sleep on low carb IF? That needs to be addressed or studied.

    You are right i was surprised of the reply google it.. It is non professionnal.. I had this problem it is related to carbs cut.. You need to eat a little carb like an apple before bed.. Mag supplement 3h before bed . Melatonin 5mg 2h before bed. And consule salt in meals.. This is temporary transition phase. Try it and tell me.

    I think the "insult" is in the eye of the beholder -- written communications cannot convey warmth behind the simplicity of the message, and so sometimes are open to misinterpretation. In this case, the message is: here are the reasons that might be related to your diet; otherwise, the general advice you can get anywhere will probably help you ... and he won't insult you by pretending he came up with it :) I suppose the answer could have been irritably short on purpose, but that does not comport with the general tone of this website. So I'd guess the insulting tone *received* was not actually the tone *intended.* (Haha, the advice on reading online stuff charitably is also readily available if you google it, too.) :)

    I find eating at bedtime is a poor habit--your body is getting ready to significantly slow down, so adding energy at that point seems a mistake, unless you are literally starving. I'd guess that's unlikely here, though.

    I'd also give it time. It sounds like you've made a major dietary shift in a very short time, and maybe your body clock is just trying to catch up!

    If diet turns out not to be the reason, and conventional wisdom doesn't help, I'd guess the next step would be to discuss it with your doctor.
