First created in the 1920s by 内科医 William Howard Hay, the Hay 国会 was created to 達成する the わずかな／ほっそりした, hip-いっそう少なく, flat-chested look of the ダンサーs.

Its 原則s have stood the 実験（する） of time and it has 獲得するd much 賞賛する by 栄養 専門家s for its far-reaching health 利益s 同様に as its ability to help manage 団体／死体 負わせる.

Unlike faddy 衝突，墜落 diets or 洗浄するs, the Hay 国会 促進するs the idea that it's not so much what you eat, but what you choose to eat with it- artist Man Rey was a 著名な fan in the 1920s and modern fans 含む Elizabeth Hurley and Catherine Zeta-Jones.

How it 作品: The Hay 国会 is based on the 原則 of segregating 確かな food types to 持続する a healthy 負わせる and the 重要な to the diet is understanding that some food groups shouldn't be 消費するd with others, but is it really 効果的な?

This is because 食餌療法している人s believe that the 団体／死体's natural ability to digest food and 燃やす fat is 妨げるd and slowed 負かす／撃墜する by 取り組むing both protein and carbohydrate foods at the same time.

In the Hay 国会 枠組み, food is also grouped into two その上の 部類s - alkaline and acidic.

This is to 確実にする that ones diet is not too acidic as this is believed to be the 原因（となる） of health 複雑化s such as 酸性の indigestion and irritable bowel syndrome (IBS).

High acidic foods they advise 避けるd are cranberries, white flour and cheese, which should be 取って代わるd by low acidic foods such as spinach, plums and eggs.

No mixing: Whilst に引き続いて the Hay 国会 no one meal should 含む／封じ込める both protein and carbohydrates at one sitting, but some nutritionists say this is 'unfounded'

'It is the perfect method for those who are looking to 器具／実施する clean, healthy habits to 上げる their fat-燃やすing abilities and 上げる their energy levels rather than a get-thin-quick 計画／陰謀 which often fails and leaves 食餌療法している人s with low energy and no 重要な difference in their 負わせる.'

Whilst it counts celebrities as fans, the theory that carbohydrate and protein rich foods should be eaten 分かれて is considered 'unfounded' by some nutritionists who （人命などを）奪う，主張する it ignores the fact that carbohydrate rich foods all 含む／封じ込める 重要な 量s of protein.
