ケトジェニックダイエット食品の世界市場規模：製品タイプ別、流通チャネル別、地域範囲別および予測

ケトジェニックダイエット食品の市場規模と予測

ケトジェニックダイエット食品市場規模は、2024年に163億8,000万米ドルと評価され、2026～2032年にかけて7.40％のCAGRで成長し、2032年までに289億9,000万米ドルに達すると予測されています。

ケトジェニックダイエットは、低炭水化物、高脂肪、中程度のタンパク質の栄養アプローチをサポートする食品に焦点を当て、身体をケトーシスとして知られる代謝状態に移行させることを目的としています。通常、身体は炭水化物からのグルコースを主要エネルギー源としています。

しかし、炭水化物を極端に減らすと、肝臓は蓄積された脂肪からケトン体を生成し、体に燃料を供給します。

ケト食に適した食品は、炭水化物が少なく、健康的な脂肪を豊富に含むように作られています。つまり、甘い飲料、シリアル、デンプン質の野菜、豆類などの食品を排除します。その代わりに、ケトーシス状態を維持しながら必須栄養素を摂取できる、デンプン質を含まない野菜、脂肪分の多い魚（サーモンやサバなど）、各種肉類、全脂肪乳製品、ナッツ類、種子類、アボカドやオリーブオイルなどの油脂類を重視します。

食材だけでなく、ケトジェニックダイエット食品産業は、既製スナック、プロテインシェイク、低炭水化物パン、代替パスタ、さらにはケトフレンドリーなデザートなど、さまざまな好みや嗜好に応える多様で便利な選択肢を提供するために拡大してきました。

この多様性により、ケトライフスタイルを実践している人々は、減量と代謝の健康に効果が期待できる、満足感のあるサステイナブル食生活を維持することができます。

ケトジェニックダイエット食品の世界市場力学

世界のケトジェニックダイエット食品市場を形成している主要市場力学は以下の通りです。

主要市場促進要因

肥満の有病率の上昇と体重管理の懸念：世界の肥満の流行が、効果的な減量ソリューションとしてのケトジェニックダイエットへの関心を高めています。世界保健機関（WHO）の2022年報告書によると、18歳以上の成人の39％が太りすぎで、13％が肥満です。International Journal of Obesityは、2020～2023年の臨床検査において、ケトジェニックダイエットを実践した人は、標準的な低脂肪ダイエットを実践した人よりも平均2.2倍体重が減少したことを記録しています。

糖尿病と代謝性疾患の増加：糖尿病人口の増加が低炭水化物食の需要を押し上げています。国際糖尿病連合は、2022年には糖尿病が5億3,700万人の成人に影響を及ぼし、2020年から16％増加すると報告しています。Journal of Diabetes Research誌に発表された臨床研究（2022年）では、ケトジェニック食を摂取した2型糖尿病患者の62%が、6ヵ月以内にHbA1c値を平均1.2%低下させたことが示されています。

スポーツ栄養学と運動能力への注目の高まり：アスリートやフィットネス愛好家は、パフォーマンス向上のためにケトジェニック食を採用するケースが増えています。Sports Nutrition Market Report 2023によると、ケト特異的スポーツサプリメントは2020～2023年にかけて45％成長し、売上高は38億米ドルに達しました。ケト食の採用を報告するプロのアスリートはこの期間に78%増加し、持久系アスリートの34%がトレーニングレジメンにケトジェニック栄養戦略を取り入れています。

主要課題

栄養不足の懸念：ケトジェニック食を厳格に守ると、著しい栄養不足に陥る可能性があることが研究で示されています。Journal of Clinical Medicine誌に発表された2022年の研究によると、長期ケト食者の約75％がマグネシウムの欠乏を示し、65％がビタミンDの最適レベル以下でした。さらに、米国国立衛生ラボは、ケトジェニック食を実践している人の約80％が最初の6ヵ月以内にミネラルの補給が必要であると報告しています。

高い初期費用の壁：ケトフレンドリーな製品に必要な特殊成分は、しばしば割高な価格設定となっています。コンシューマー・レポートによる2021年の市場分析によると、ケトフレンドリーな代替品は従来型代替品より30～50％高いことがわかりました。例えば、ケトに特化したパン製品は1斤あたり平均9.99ドルであるのに対し、通常のパンは3.99ドルです。国際食品情報評議会（IFIC）が2023年に行った調査では、ケト食を取り入れる可能性のある人の68%が、導入の大きな障壁としてコストを挙げていました。

限られた製品の入手可能性と入手しやすさ：市場の関心が高まっているにもかかわらず、流通面での課題は依然として大きいです。2022年の小売市場分析によると、従来型食料品店のうちケト専用コーナーを設置しているのはわずか23％でした。Food Marketing Instituteの報告によると、ケト製品に関心のある消費者の約45%が、地元の店舗でケト製品を見つけるのが困難でした。

主要動向

競技パフォーマンスの上昇と有名人の支持：アスリートや有名人の間でケト食が採用されていることが、市場の成長に大きく影響しています。2022年のスポーツ栄養市場レポートによると、プロのアスリートの約28％がケトジェニックまたは改良ケトジェニックダイエットを実践していると報告しています。2023年のソーシャルメディア分析によると、フィットネスインフルエンサーによるケト関連のコンテンツは、TikTokだけで21億回以上のビューを生み出しました。

レディトゥイートケト製品とコンビニエンス食品：便利なケトフレンドリーオプションの需要が急増しています。Food Navigator USAの市場調査（2023年）によると、レディトゥイートケト食の売上は2020～2023年の間に86%成長しました。ケト市場の利便性部門は2022年に47億米ドルに達し、食事代替製品はケト製品総売上の32％を占めました。ニールセンのレポートによると、ケトフレンドリーなスナックオプションは、2020～2022年の間に小売店での存在感が124%増加しました。

デジタル統合とパーソナライズされたケトソリューション：技術とケト食プランニングの統合は、強い動向として浮上しています。2023年デジタルヘルス市場分析によると、ケトに特化した食事計画アプリのダウンロード数は2020～2023年に165％増加しました。International Digital Health Federationの報告によると、ケトダイエッターの約38％が専用のトラッキングアプリを使用しており、パーソナライズされたケトコーチングプラットフォームは2022年に契約数が92％増加しました。

Ketogenic Diet Food Market Size And Forecast

The Ketogenic Diet Food Market size was valued at USD 16.38 Billion in 2024 and is projected to reach USD 28.99 Billion by 2032, growing at a CAGR of 7.40% from 2026 to 2032.

The ketogenic diet focuses on foods that support a low-carbohydrate, high-fat, and moderate-protein nutritional approach, aimed at shifting the body into a metabolic state known as ketosis. Typically, the body uses glucose from carbohydrates as its main energy source.

However, when carbs are drastically reduced, the liver produces ketones from stored fat to fuel the body, marking the core concept of the keto diet.

Keto-friendly foods are crafted to be low in carbs while rich in healthy fats. This means eliminating foods like sugary drinks, cereals, starchy vegetables, and legumes. Instead, the diet emphasizes non-starchy vegetables, fatty fish (such as salmon and mackerel), various meats, full-fat dairy, nuts, seeds, and oils like avocado and olive oil, all of which provide essential nutrients while maintaining ketosis.

Beyond just ingredients, the ketogenic diet food industry has expanded to offer diverse, convenient options that cater to different tastes and preferences, such as pre-made snacks, protein shakes, low-carb bread, pasta alternatives, and even keto-friendly desserts.

This variety allows those following the keto lifestyle to maintain a satisfying, sustainable diet with potential benefits for weight loss and metabolic health.
