I'm trying "The Organ Diet" for next 6 days. Sat thru Thursday.

[arakboss]

I will be eating about 1000 calories a day. This roughly equals the amount of energy the body's organs burn at rest per day. That means any other energy expenditures will have to come from my generously sized reserves. I will post a screenshot of my food intake and weigh in each day starting Sunday morning through the last day Friday the 27th.

Here is link to where I found estimates of organ energy expenditures.

Specific metabolic rates of major organs and tissues across adulthood: evaluation by mechanistic model of resting energy expenditure

Background: The specific resting metabolic rates (K[i] ; in kcal · kg[−1] · d[−1] ) of major organs and tissues in adults were suggested by Elia (in Energy metabolism: tissue determinants and cellular corollaries. New ...

200 for liver, 240 for brain, 440 for heart and kidneys, 13 for skeletal muscle, 4.5 for adipose tissue, and 12 for residual organs and tissues.

I am leaning towards Protein Sparing Modified Fast menu to get my 1000 calories in. I will continue with light resistance training but very little cardio.

I just weighed in at 207 on the nose, Organ Diet starts today.




Edit: I am trying to get to 200 or less by July 4th. That will leave me with July, Aug, Sept and Oct to shed the remaining 25lbs.

Some might consider a 1000 calorie diet extreme but consider this. I have an extra 32 lbs of adipose tissue on me which translates into roughly 112,000 calories of energy reserves. I have until the end of Oct or 160ish days to use up that 112,000 calories. That means I need to burn about 700 calories per day of my reserves. I am not sure what my total daily energy expenditure is on a typical day but it is probably not much too much higher than 1700 calories. I would rather not wait until the last day of my weightloss challenge to make my goal weight so I will want my TDEE to be higher than 700 calories plus whatever calories I am taking in everyday.

Are you moving more or just cutting calories?

Gotta do both to maximize your weight loss.

I have had little extra energy for walks lately but did get one in this morning.

You might want to do some reading on metabolic set point and adjust your calculations accordingly. A simple calculation of calories vs basal metabolic rate over time is inaccurate because your body changes as it reacts to the diet.

Edit - just noticed this is a six day diet. So set point probably won't impact you.

I have been doing a lot of research regarding adaptive thermogenesis. I think it's very difficult to know how much of that occurs. The research studies are all over the place. I am going to have to keep the calories lower for the next four months or so, hopefully not at 1000.

Biolayne made this video on how the fat cells shrink, multiply and regain a set point with yo yo dieting.

 

[monkeybutler]

Yup.

I think of (cardio) exercise as not as a way to lose weight but as a hedge against metabolic slowing.

Somebody who knows way more than me about this stuff commented that he lifts weights as the same kind of hedge. Makes sense to me.

Not a good start to my diet weigh in, scale said 208.2lbs this morning, yesterday was 207lbs. I just about hit my target of 1000 calories but went a little over. The only food I didn't count was spinach, romaine lettuce and a tomato. I got in three walks yesterday and a few minutes of resistance exercise.

I came up short hitting my protein goal and I might have to revise that goal downwards or bump up the calories a bit to get 170grams of protein a day. If I continue this 1000 calorie diet beyond the six days I will probably add a cheat meal day in once a week and bump the calories up to 1200 per day.

 

[arakboss]

Day 2 results not good. My weight has jumped up to 210lbs Menu list doesn't include vegetables/greens that I ate today. Came up short on protein goal again.

Tell us about your salt intake.

 

[arakboss]

Tell us about your salt intake.

500mg sat
1900mg sun
800mg so far today.

I weighed this morning and was 213.8lbs so I am retaining water bad. I expect at some point that water will fall off, hopefully soon.

Retaining that much water aint healthy. Something funky is going on.

In that case.

Yes, that dress, makes your arze look huge.

I cut my caffeine intake way back for this diet. Maybe my body is relaxing a bit and hanging on to more water, without the diuretic effect of the caffeine? I am going to stick with the diet through at least Thursday, I know the weight gain can't be from fat as I have eaten less than 4000 total calories (including vege) since Saturday morning. My metabolic rate may be low but it ain't that low. I am going to take two caffeine pills tonight (400mg total) and see if that does anything for me. Work is going to be a real slog again this week.

Body may be going into "starvation" mode and storing the fat, instead of burning it.

I am eating just enough calories to supply my organs with enough energy to function. It seems impossible that my body could be finding an energy surplus at this level of caloric restriction. I have been losing weight at 1500 calories per day (plus vege) but not fast enough to make my goal. I haven't found a physiological explanation for the "woosh" effect but I am betting that it happens to me this week (I hope).
