Portion Estimation

Portion control drives energy balance, but most people don't want to weigh food forever. Two practical estimation systems:

Hand portions (scale with body size, so they self-adjust):

• Protein: a palm-sized portion (~20–30 g protein) per meal — e.g., 2 palms for larger or muscle-building appetites (see protein).
• Carbohydrate: a cupped-hand / fist-sized portion of grains, starches, or fruit.
• Fats: a thumb-sized portion of oils, nut butters, or cheese (energy-dense — see dietary-fats).
• Vegetables: a fist or two — high volume, low calories; fill up here.

The plate method: fill ½ the plate with vegetables/fruit, ¼ with lean protein, and ¼ with whole-grain or starchy carbohydrate, with a small amount of healthy fat. Simple, no counting, and naturally portion-controlled.

Visual cues for reference: a deck of cards ≈ 3 oz meat; a tennis ball ≈ 1 cup; a golf ball ≈ 2 tbsp; a thumb tip ≈ 1 tsp. Calibrate occasionally by weighing a few foods so your hand/eye estimates stay honest — portions tend to drift larger over time, which is a common hidden cause of stalled fat loss. For label foods, anchor to the stated serving size (see nutrition-labels).

• Hand portions: palm = protein, fist/cupped hand = carbs, thumb = fats, fist+ = veg.
• Plate method: ½ vegetables/fruit, ¼ protein, ¼ whole-grain/starchy carb.
• Visual cues: deck of cards ≈ 3 oz; tennis ball ≈ 1 cup; thumb tip ≈ 1 tsp.
• Hand portions self-scale with body size.
• Recalibrate by occasionally weighing food; portions drift larger over time.

• nutrition-labels — serving sizes anchor portions.
• calorie-targets — portions execute the calorie goal.
• meal-planning — building meals from portions.
• eating-out — estimating restaurant portions.
