Dr Boz Food Guide

Getting Started With Dr Boz Food Guide

I first came across the Dr Boz Food Guide about three years ago when someone linked it in a forum thread. I wasn't expecting it to be much, but the macros it laid out actually held up during my meal prep cycle. The core idea is straightforward: you pick a food category, log your serving size, and it maps everything onto a daily macro target. That's it in a sentence. But the way it handles food substitutions and the nested carb/fat ratios is where most people hit trouble. The guide works by assigning each food an index value based on its macronutrient density relative to a baseline. Most people skip past the setup section and start plugging numbers in, which leads to errors. Here's the correct way to run through it. Open the main spreadsheet. Row 1 is your weight class and activity multiplier. Rows 2 through 8 are the food groups. Each cell contains a conversion factor that translates raw weight into a standardized unit. You don't input raw grams unless you're using the custom entry column, which only appears if you check the advanced toggle in cell B3. I learned this the hard way. My first attempt took me two weeks because I kept forgetting to set the activity multiplier, which meant every single entry came back at a default sedentary baseline. That put me roughly 400 calories under where my actual needs were. Once I set the multiplier based on weekly training volume, the outputs aligned with my bodyweight changes within four days instead of six.

Common Mistakes That Wipe Out Accuracy

Most of the feedback I see online about this guide failing comes from one of three sources. First, people input whole food weights instead of drained/drained weights for canned or packaged items. The guide assumes you're entering the edible portion, not the packaging weight. Second, they skip the cooking adjustment row. Raw chicken and cooked chicken carry different water content, which shifts the protein density by roughly 18%. Third, and this is the big one, people apply the guide to heavily processed foods without checking the index column first. The guide's database was built around whole foods and standard supplements. A protein bar with 20 different ingredients doesn't fit cleanly into any single row, so the conversion factor breaks down. When I ran into the processed food issue, I stopped trying to force entries into the guide and instead built a small lookup table in a separate tab. I matched each bar or shake to its closest whole-food equivalent using the protein-to-calorie ratio, then applied the guide's multiplier to that proxy. It wasn't perfect, but it got me within 5 percent of my actual intake versus weighing every ingredient separately, which used to take me about 45 minutes per day.

How to Set It Up Properly

Start with your current bodyweight in kilograms. Multiply that by 0.9 for a cutting phase or 1.1 for a bulk. That gives you your daily gram target for protein. The guide uses that number as the anchor point. Everything else derives from it. For carbs, the formula isn't fixed — it's tied to your training days. A light day pulls from the lower band, a heavy leg day pulls from the upper band. Fat sits at the residual. This means the spreadsheet will shift your targets slightly depending on what you enter in the training column. I keep my training column auto-populated by linking it to a simple calendar sheet where I log workouts. That way I'm not manually updating anything. One person on Reddit shared a version that uses Google Apps Script to pull from Google Calendar automatically, but the formula gets fragile if your event names aren't consistent. I'd only recommend that if you're comfortable debugging broken sheets.

Where The Guide Falls Short

It doesn't handle micronutrients at all. You won't find any mention of fiber targets, sodium, or potassium. If you're running a cut and hitting constipation issues, the guide won't flag it. You need to layer that on yourself or cross-reference with a separate tracker. Another gap is hydration. The water recommendation is hardcoded to a flat 3 liters regardless of bodyweight or climate, which is useless if you're training in anything above 75 degrees Fahrenheit. I bumped mine to 3.5 liters on hot days and adjusted based on urine color, not the guide's suggestion. There's also no integration with popular tracking apps. You're working with a spreadsheet, period. If your workflow depends on logging into MyFitnessPal or Cronometer, this adds an extra step. I just copy the row totals into my app after the guide generates them. Takes about 90 seconds. For anyone just getting started, the learning curve is maybe six sessions. After that, it runs on autopilot. The values are solid enough for most people tracking to within 10 percent accuracy, which is fine unless you're preparing for a competitive physique show where the margin is tighter. In that case, you'd want to supplement with a food scale and laboratory-grade nutrition labels, or pivot to a more granular system like the one from Precision Nutrition.
