• Synonym過食かしょくWrittenEating to excess; also the symptom seen in eating disorders. Mostly medical, but fine in daily use too, as in 「ストレスで過食する」.
• Synonym暴食ぼうしょくWrittenStresses eating with no restraint — gluttony. Often paired with 「暴飲」 as 「暴飲暴食」. Weighs heavier than 「食べ過ぎ」.
• Synonym食いすぎくいすぎCasualSame meaning, but built on the rougher verb 「食う」; mostly men's casual talk. Use 「食べ過ぎ」 in formal situations.
• Antonym節食せっしょくNeutralAntonym: consciously eating less — to lose weight, save money, or for health. Points the opposite way from 「食べ過ぎ」.
• Antonym絶食ぜっしょくWrittenAntonym: taking no food at all, usually for treatment, medical tests, or protest — the extreme opposite of 「食べ過ぎ」.

For everyday 'ate too much', use 「食べ過ぎ」. 「食いすぎ」 is rough casual speech; 「過食」 suits medical or formal contexts; 「暴食」 stresses unrestrained gluttony and is harsher. The antonyms are 「節食」 (cutting back) and 「絶食」 (fasting).
