Diets work temporarily.
If you want/need something long-lasting, change your lifestyle, including your diet/nutrition, exercise habits.
Lifestyle changes succeed long-term.
Intermitten Fasting is the way to go.
Permanent changes. Yep.
I have found several things I can permanently change. Stuff like switching from lattes to cappuccinos. Using low cal mayo instead of regular. Weighing out my cereal so I stay aware. Etc.
For life! Or it doesn’t work.
