In reply to Roberto.

Read the article Is Rapid Fat Loss Right for You? I addressed the metabolic slowdown issue in this piece already.

Lyle, everyone always says diet slow and less aggressive because of metabolic adaptions and that the body will “get use to the lower intake” faster then if you were to cut slowly but wont the metabolism basically only adapt based on the reduction on body weight and that the adaptive component is just simply overblown and the main true reason why people shouldn’t cut aggressively is just because of the mental stress and higher possibility of loss of muscle. the arguments for adaptions happening really soon and basically cutting to aggressive and “running out of room to pull from much sooner then if dieted slower” since u started to aggressive and have now adapted is that argument just nonsense in your opinion because i hear mixed opinions everywhere and want to know your views on both points

I am seeking your advice as I find your informations so valuable however im unclear how to apply it to myself.
I am a 33 yr old mum 72kg 30%BF 163cm . I am a habitual dieter whose diet has stalled for 6 months now. I wear a fitbit activity tracker and my average expenditure is 2500 cal a day and im eating 1600 and am not losing weight. I use a food scale and MFP. I do a cross fit style class twice a week ( HRM says 1000 calorie) and one full weights session a week ( 500 cal). I was also doing 1 hr brisk walks per day as well as training qat the gym but have stopped in an experiment to remove excessive cardio and focus on weights.
I have had my RMR tested and it was 1440 cal at rest. I went to a dietician who told me just eat 1200 cal but I feel exhausted and Hangry when I do that.
I have been focusing on increasing protein and watching my macros to find a balance 40/40/30
my fitness has improved out of sight however I cannot seem lose weight and its driving me crazy and im not seeing any measurable fat loss. im frustrated as simple maths is not working for me
what am I doing wrong?

should a aim for a smaller deficit? take a diet break? ( insert crazy lady OMG weight gain gif)

Im not looking for an easy solution . I understand body composition changes take time however I would expect to see progress after 6 months

any guidance you could provide would be greatly appreciated

thanks in advance

Hey Lyle,

I recently graduated from university, and found in the last months leading up to my graduation, i significantly let myself down – i put on almost 8 kgs! 🙁
I have been reading a lot of the articles you have posted and found myself a little relieved and a little perplexed.
Having coming back home for a holiday, 1 month and a couple of days to be precise, I decided that with the availability of healthy food, a gym right around the corner, and my mom to help keep me on track, this might the perfect (and only) opportunity for me to drop those kgs, and fast.
For about 1.5 weeks now, I have been trying to burn around 1000 calories minimum with a combination of cardio/weights per day, and i have cut out carbs from my diet almost completely, save for a spoon or two of rice or buckwheat pasta a day, so it is safe to say that my caloric intake would not be more than 1000 a day.
Is what i am doing alright? Will I be able to drop the 6kgs by the time 3 weeks come to an end? I know its sounds rash, but after trying a gazillion types of workouts, this is my last resort, and quite frankly, my last hope.

I really appreciate anything you have to say.
Thanks in advance! 🙂

Great article, and one of many I’ve read tonight, but one thing I’m confused about is the largest deficit’s impact on metabolic parameters.

Is this a permanent impact or something that irons itself out after a while?

For example, if one lost 50lbs through 33%-50% deficit, would their metabolism be permanently lowered as opposed to a person who took longer to lose the same amount of weight via a 10% deficit?

And by permanently lowered, I mean even if the weight were gained back, the metabolism would be permanently ‘damaged’.

Great article Lyle, very clear and lays out the behavioural aspects alongside the physiological. Interesting about the macro set-up for larger deficit diets being so poor. No wonder there was muscle loss.

I suppose in premise this is possible (MAP anybody?) but I still don’t think it’s a good idea. Such a product wouldn’t do anything for fullness, satiety or long-term food habits which are just as important as anything that might be gained from it.

I have a question and I want to preface it with this: I AM NOT TRYING THIS,JUST CURIOUS

Based on RAPID FATLOSS HANDBOOK, which I have read

If a person takes a great full spectrum amino supplement would that allow for a human to reduce food calories and spare organ breakdown in the body? Essentailly seriously reducing calories with out reducing “the building blocks” and essential nutrients for survival?

At some later date I will explain what I think is hapepening in full. For now, simply take it at face value and/or MAGIC! But that’s what invariably happens.

Hi Lyle,

Your articles are fantastic.
However, I do have a question.
I’ve read both here, and in one of your books (Rapid Fat Loss Handbook) that engaging in a lot of activity (mainly aerobic) while on a very low calorie diet can slow weight loss efforts?
Why is this?
If one has a high caloric deficit and then increases that with exercise, according to the energy balance equation wouldn’t that increase weight loss? I understand that with such a big deficit, the negative hormonal responses of your body are increased but you yourself have said that they’re not enough to eliminate the deficit completely.

If you could clear this up for me it would be much appreciated!!
