But it requires massive willpower to overcome those first few days of cravings, pain and mental anguish and then extended willpower to keep it going for at least 30 days so you can build some tolerance to the new reality of clean eating and exercise...and then even more willpower after losing all the weight not to fall back into a bad habit and refill all those dormant empty fat cells that your body does not destroy for at least 7 years. Combine that with the fact that a lot of people are living paycheck to paycheck/working multiple jobs to survive and may not have access to clean nutritious foods without extended effort and you see how we ended up in this situation.
