Bulking starter guide: the first 14 days

A bulk rarely fails for lack of motivation: it fails because you start too hard, too vaguely, or without a system. The first fourteen days are for locking in a realistic surplus, meals you can keep, and tracking light enough to last past the first burst of energy.

Set the number first. Estimate your TDEE (total needs), then aim for a moderate surplus of 200 to 400 kcal per day — not a “dirty bulk” of +800 kcal that mostly inflates fat mass. A pace of +0.25 to +0.5% of body weight per week is a good landmark for a clean bulk. Daizu’s calorie-needs calculator gives you a baseline in three minutes if you do not have a number yet.

Lock in protein from day 1: 1.6 to 2.2 g per kg of body weight. For 75 kg, that is about 120 to 165 g per day, spread over 3 to 5 servings. Carbs support sessions (rice, pasta, potatoes, fruit); fats stay comfortable without crushing food volume. You do not need a perfect spreadsheet — you need a target and meals that carry it.

Structure a typical day rather than a list of “good foods.” A simple example: a protein breakfast + starch, lunch of protein / starch / vegetables, a post-workout snack (Greek yogurt, a shake, bread + eggs), a generous but easy-to-digest dinner. If you struggle to eat enough, first increase the starch bowl and add a snack, before stacking sauces and fried food “for the calories.”

Groceries and meal prep decide whether you last two weeks. Sunday or Monday: cook a starch in large volume, a neutral protein (chicken, 5% ground meat, tofu, tuna), roasted vegetables, and plan easy dense foods (oats, fromage blanc, peanut butter, dried fruit). Without those bases, the surplus depends on delivery — and the bulk becomes uncontrollable.

Tracking without obsession. Weigh yourself once a week, same conditions. Note strength on 2–3 key lifts (bench, squat, row…): if the loads stall three weeks in a row while you are eating in a surplus, the problem is often sleep or the program, not “not enough calories.” Restaurant slips get logged; they do not cancel the week.

Classic mistakes of the first two weeks: a surplus that is too big from the start, zero vegetables (“I’m bulking”), skipping tracking because “I eat a lot anyway,” and believing you have to finish every plate until you feel sick. A clean bulk is a controlled surplus + progressive training, not a buffet contest.

Action plan day 1 → day 14. Day 1: calculate TDEE + surplus, set the protein target. Day 2: grocery list and batch the bases. Days 3–7: follow the menu, adjust portions if you are not hungry or if you struggle to finish. Day 8: weigh-in + strength review. Days 9–14: stabilize the rhythm, correct one lever at a time (starch portion or snack), and decide whether the surplus stays in the 200–400 kcal range.

Daizu can carry this start as a nutrition program with tracking: you enter a bulking goal, the app calibrates menus and calories, generates the grocery list, and lets you log the unexpected by photo. It is not a medical device — for a high-level sports protocol or a clinical need, a professional remains the reference — but it is a system for holding the first fourteen days without improvising every evening.
