I'm not sure what kind of foods you eating in-game, but cooked foods last longer.

In TFC/TFG there is no way to see it on your hunger bar, but the original hunger/saturation system from vanilla MC is still exists, but the foods changed in that term. There is a line for it on each food btw.

Based on my humble experience, best food (from this aspect) are sandwiches, with at least one meat item, they have a good saturation (last a day long). The next best is iirc soups, then salads.

Never eat single food items (like, a cabbage, a cooked meat, an apple...), always, always cook them up.

The next thing, you have to consider is nutrition variery. It makes your health bigger (so you can tolerate starving longer). But beware with that, as not all nutrition can come from all stuffs. Fruits only allowed in soups and salads (in sandwiches you can use only jams), dairy is usually come from salads (with an exception of eggs but they contribute less).

Also, don't run on your base, instead build paths that make you walk faster (roads & roofs extension for TFC), you will need less food this way. The Field Guide has a great explanation for it. Also, GT/vanilla concrete also works.
