ok. Not sure how overweight you are but regardless honestly I would start looking at all bread, rice, pasta and potatoes as treats instead of regular staples. for life. junk food or not. learn to love sweet potatoes and quinoa if you don't already. those 2 are good. black beans are good too.
the problem is we collectively eat too much sugar, including all the things that metabolize into sugar(your complex carbs/starches). you have to starve yourself of sugar and re-train your body to use fat as an energy source.
fruit also becomes a treat under this model, with the exception of berries which are A+ since they are comparatively low sugar and high fibre. they are my primary fruit source for that reason.
when I first quit ingesting sugar for the most part, I couldn't even taste 5 packs of monkfruit sweetener in my coffee (oh yeah, stop using splenda/artificial sweeteners....they may not have calories or rot your teeth, but the effect on insulin remains...this is why it's coming out now that they commonly cause weight gain, instead of the opposite). this is because we are used to the "10" on the sweetness meter refined sugar and sweeteners provide. once you quit that stuff, your tasting of food and relative sweetness will change pretty quickly.
in the popular imagination, fat and total calories in/calories out have dominated the weight loss discourse, when in reality this is totally the wrong way to look at it. the true issue for many is sugar, insulin, and insulin resistance. Not all calories are equivalent and what type they are is more important than how many.
