Test yourself if you're overweight, or feeling out-of-shape; Stop drinking soda for three days. See how you feel. It might surprise you how much sugar you ingest.
Stop eating potato chips and french fries for a week. See how your gut feels.
Start noticing your buying habits. Are you always going to the corner store to buy beer? How do you think your body reacts to 3-4 beers every day, of carbonated alcohol-water? Your liver has to eliminate that poison. Your gut has to deal with digesting fried bar foods while processing that carbonated alcohol.
Eat apples and bananas. Fresh ones you buy from the grocery store, not the mealy old ones you get at the corner store. Start craving something crisp and crunchy and only slightly sweet.
