Keeping a Food Diary: Tracking Your Nutrition During the Transition

Why Keep a Food Diary

The most common problem during the transition isn't “eating something you shouldn't,” but “not eating enough of what you should”—protein and iron intake, for instance, can quietly drop without you noticing. A food diary makes this kind of hidden problem visible.

A Simple, Workable Method

• Snap a photo of each meal, or jot down the main food types in a few words—no need to weigh anything precisely
• Review once a week to check whether protein sources (beans, soy products, nuts) are showing up every day
• Pay attention to how often leafy greens, whole grains, and nuts and seeds appear

No Need to Overdo It

You don't need a specialized app calculating every gram of every nutrient right out of the gate. Simple notes or a basic table, kept up for 2 to 4 weeks, is already enough to reveal any obvious gaps in your diet.

Advice for Beginners

Tracking is about understanding yourself, not about being hard on yourself. If you notice you're eating too little of something, just work it back in the following week. The format doesn't matter—use your phone's notes app, snap quick photos, or simply check a box on your calendar for “did I get enough protein today.” Whatever you can actually stick with and easily look back on is the right method for you. After keeping it up for a while, you'll have a much clearer picture of your own eating habits—and that understanding is valuable in itself.
