It’s really a combination of healthy living and healthy eating.
A habit needs to be developed where some sort of exercise is undertaken on a regular basis. This must be coupled with healthy eating. I find there are alot of foods that can be avoided quite easily.
I think this is just restating what niksik said.
Also, dont starve. Ever. After starving people tend to eat ALOT which is not good.
Eating alot isn’t always the problem as much as how often you eat. If you take the amount of food you eat over 3 meals and eat it instead over 6 it will be alot healthier. Infact you’d be probably eating more over the 6 meals but it still wouldn’t be as bad as sitting down for 3 and just going bonkers; that would result in a bloating feeling.
