# Thread: Scooby's Fat Loss Calculator

1. ## Scooby's Fat Loss Calculator

http://www.scoobysworkshop.com/caloriecalculator.htm

Any opinions on the variables he selects in calculating calories needed to maintain, and/or lose fat? Seems that any "fat calculator" will be hard pressed to quantify metabolic rates per individual.

So far, it seems to work, in the sense that, I'm now counting calories and protein grams for the first time ever. Calculating what I'm putting onto my plate, and recording it, rather than using the old, "I think this is roughly x calories/protein" approach, I think, is making most of the difference.

I'm 43, 200 lbs., 69" tall, and I'm shooting for a 25% calorie reduction. So, my macro intake, according to Scooby, should be 40/40/20 @ 6 meals per day. I selected 5-6 hours per week of strenuous exercise, and the final calculation results were as follows:

Basal Metabolic Rate: 1926
Daily calories to maintain weight (TDEE): 3323
Daily calories based on a reduction goal of 25% less calories (below maintenance) per day: 2492

2. btw, 2492 calories for a 25% calorie deficit below daily maintenance seems like a lot of calories. I would have guess that my maintenance wouldve lower by a few hundred, thereby placing me below 2000 calories per day to cut by 25%. I know if I go below 2000 calories per day, I will be quite miserable and highly irritable!

3. Bump^^

4. I'm about the same stat's as you. 69" 190lbs. wanting to be 175-180 at low bf. I have been using his calculator and tracking my food at fitday.com

By eating clean, working out and tracking my Macro's I have lost probably 5 lbs of fat while adding muscle in a very short period of time maybe 20 day's. So he stuff work's or is pretty close. Play with your macro's and see what work's for you as everyone's body/metabolism etc. is different.

5. seems to calculate on the low side for BMR. (about 200 cals from others I have seen) There is a thread around here somewhere where they posted a great calculator in excel format. But if you look in the stickies you should find some more accurate info.

Also I would not cut by % cals but rather by a specific amount such as 500 (= 1lb per week loss)

First, although the equations used to calculate this are complex, they are just a very good educated guess! They could be off by 10% but this is far,far better than any chart or rule of thumb but not nearly as good as the real world.

The thing thats really, really tough to take into account is the exercise and its effect on the BMR. How does walking 8hours a day like a postman does compare to 20 minutes of HIIT? How does a 60 minute powerlifting workout compare to a 2 hour bikeride or a 1 hour swim?

Here is what you need to do. Choose a calculator, count calories for two months while carefully monitoring your bodyfat with a skinfold caliper and weighing yourself every day. At the end of the two months, see how the calculator's predicted results compare with reality. For example, if my calculator said you should be losing fat at the rate of 5lbs a month but you lose 6 pounds of fat, then you know that for you, you need to add 116 calories ((3500x1)/30) per day to whatever the calculator tells you.

lol OMG! is this the THE SCOOBY? huge fan lol, love you're youtube coaching lessons, welcome. To the OP give or take a few calories, my stats etc, my plan is pretty much the same and sounds right, good job, I have been consistent from 190ish of dropping 1-2 lbs per week on this plan like you'res-Ty, FYI I'm low 170ish now about 13% bf coming from 22%bf

Talk about good counterintelligence and I'm not talking about the Scooby-Doo guy
