Oatmeal vs White Rice
Straight answer: the per-100g table flatters rice only because the two rows stand on different bases — the oatmeal row is weighed dry (389 kcal/100g) while the rice row is weighed as served, cooked (130 kcal/100g). Put each on its real plate and the picture flips: half a cup of dry oats (40g ≈ 155.6 kcal) comes out lighter than one cup of cooked rice (150g = 195 kcal), and brings 4g of fiber along against the rice's 0.6g. Oats win the staying-full game; rice wins the fast-fuel game — the verdicts below split the rest by goal.

Which one, for which goal
For a calorie deficit
Oats, and the reason is the fiber line: 4g inside the 40g bowl (the rice cup carries 0.6g) — and their soluble fraction is the most-studied satiety lever among breakfast grains. A bowl that keeps the morning quiet until lunch is worth more to a deficit than a 39-kcal arithmetic edge.
Fuel around training
Rice. The cooked cup delivers 42g of carbohydrates that arrive fast and sit light — restocking what a heavy session spent without making the stomach negotiate first. Oats' 26.4g come packaged with the very fiber that slows them down, which is the wrong direction when the clock says "train soon".
The basis honesty
Whichever you eat, weigh it the way your tracker expects: oats dry or cooked — but consistently — and rice cooked. Both bowls fit a budgeted cut (155.6 vs 195 kcal on the real servings); the deficit dies from uncounted oil and toppings long before it dies from the grain choice.
Common questions
Is oatmeal fewer calories than rice?
On real servings, yes: 40g of dry oats ≈ 155.6 kcal while a 150g cup of cooked rice = 195 kcal. The per-100g column looks inverted (389 vs 130) only because oats are listed dry and rice cooked — compare plates, not bases.
Which one has more fiber?
Oats, by a wide margin: 10g per 100g dry — 4g in the standard bowl — against rice's 0.4g per 100g cooked (0.6g per cup). That fiber gap is the whole satiety argument of this comparison.
Can I keep both in a fat-loss plan?
Yes — and it often works better than banning either: oats for the slow morning, rice around training when speed matters, each counted at its real serving. The plan fails on the untracked extras, not on having two carb sources in the kitchen.
