I have gained and lost a ton of weight several times in my life. While I did also notice and make use of the hormone imbalances that affect me (depending on where your fat is you can estimate what hormone is acting up), in my experience it has been that food appetite or enjoyment is maybe 10% of the struggle with another 10% being environmental factors but 80% comes down to the answer to a simple question: Is the advantage or profit of weight loss worth the discomfort and hard work? We all know objectively speaking it is, but as an individual, do I care enough? What do I get out if it in the end that is worth it, for me?
