@captaineight - this forum addresses healthy lifestyle, including weight management, based on Sisson's The Primal Blueprint.

This is evidenced by the fact of the body achieving homeostatisis despite variation in input and overt expenditure. The secret to wellbeing is understanding how we can restore our endocrine systems to healthy function. Good things follow
