My FitDay today - (after I have lunch & afternoon snack) has a total of: Calories = 1100 Fat = 41g Carb = 113g Protein = 69g But on the "percentage wheel" it looks like this: Fat 36% Carb 38% Protein 27% I just DON'T get the math here!!!! I thought I was doing well to have 69g of protein & only 41g of fat. But percentage wise, Fat 36 & Protein 27... how can it be so much less??? And because I'm so utterly confused with the math proportions, I'm thinking I shouldn't be doing a "mathmetically directed" diet. Some days are just MORE DUH than others, I guess. __________________ CHANGE IS HARD. BUT PERPETUAL DISSATISFACTION AIN'T NO PICNIC EITHER!

So of your 1100 calories: -(41g x 9 cal) 369 calories are from Fat (34% -(113g x 4 cal) 452 calories are from Carbs (41%) -(69g x 4 cal) 276 are from Protein (25%) At least, that's what my math comes up with. It's a little different from your FitDay %, but not by too much The difference in percentage on Fit Day (compared to my percentages) could be explained by fiber. Of your carbs, the fiber wouldn't have 4 cal/gram because it's indigestible. Fit Day will list the "total" carbs, but it likely takes fiber into account and doesn't count the fiber toward your calories or percentage, which would account for the slight shift from the percentages I came up with (meaning that where I found 41% carbs, FitDay lists it as less--38% because of your fiber. When that % goes down, the other two values for Fat/Protein go up) I hope that made sense... Last edited by Azure; 11-12-2007 at 01:56 PM.

Fat is just a really energy-rich food, which is why it's so easy to go over on calories when eating something like butter or full-fat salad dressing. Those things have to be carefully measured.

It's the TOTAL CALORIES that depict weight loss....? All my life I've understood that your intake & output of TOTAL CALORIES is what weight loss (or gain) is all about. Therefore, if I'm eating 1800 (give or take) calories per day, & I want to lose 1-2 pounds per week, I should drop 300-500 PER DAY. Regardless of WHERE those calories come from. Right? (and why am I suddenly getting so many brain farts in this area????) __________________ CHANGE IS HARD. BUT PERPETUAL DISSATISFACTION AIN'T NO PICNIC EITHER!

But it's pretty obvious that if you ate 1800 calories of butter, it would not be the same as eating 1800 calories of whole wheat bread. Nutrition is more complicated than the laws of physics. Different types of programs use different percentages for protein/fat/carb. I've been using what I think are the Zone percentages--or I try, anyway--which is 30/30/40. Does that make it any clearer?

Could you lose weight eating 1500 calories of doughnuts a day? Yes. But you probably will feel like crap if you do it that way That's where the macronutrients come in: where do you put them so that you feel satisfied all day long and have energy? For me, I'm on a very low carb diet (a ketogenic diet) and my macros are more like 6% carbs / 44% protein/ 50% fat on a daily basis. Those ratios keep me feeling full all day on 1500 calories/day. Other people have a lot of success with other ratios...it really depends on how your body handles different foods. But in the end, whether I'm eating 6% carb/44% protein/50% fat ratio on 1500 calories a day or 60% carb/ 25% protein/15% fat ratio on 1500 calories a day, I'm still in the same caloric deficit and I'll drop the same amount of weight per week (technically). But for me, if I ate 60% carbs a day I'd be miserable and STARVING on 1500 a day, whereas I'm completely satisfied on 6% (all coming from vegetables) with the rest being protein and fat for that many calories. I don't mean to be confusing...I hope it helps? The macronutrient breakdown is really individual, it's the calorie deficit that ultimately matters. Last edited by Azure; 11-12-2007 at 05:40 PM.
