The KETOGAINS MACRO CALCULATOR and How to Set Up Your Macros

FINAL NOTES AND CONSIDERATIONS:　より一部抜粋
It is not suggested you do extreme caloric deficits (more than 25%) unless you have a very high BF%, as you may risk either losing muscle or not having enough energy to hit the gym.
Again, a safe bet is to cut around 500 kcals from TDEE when dieting, and to add 200 kcals when wanting to add muscle.

ketogainsのFAQにも、-25%超はextreme caloric deficits、TDEE-500kcalまでが安全圏と書いてあり、これが導入期限定の注意事項とは読み取れない
“unless you have a very high BF%,” を適用できるスペックかどうかは自身でご判断を
導入後に大胆にカロリーカットしていっても代謝低下に抗える身体資本を持ってるフィジカルエリート様は自己責任でおながいしたい
