I think all of that are contributors to the obesity rate in both the United States and the UK. The bottom line is people need to be more disciplined with better food choices and eating patterns. Food choices meaning staying away from the Fast Food/Fatty Foods and eating patterns meaning not snacking on potato chips, cookies, and stuff like that between meals and late at night. The alcohol consumption needs to be done in moderation as well. I don't have a problem at all have a drink or two each night, but when it becomes a high amount consumed each day that is not good. Depression definitely can lead to wanting to snack to attempt to cover up the depression.
