Back to basics: High fiber, low fat, very low saturated fat, very low sugar (simple carbs), no juice, no soda, no gatorade. Limit sweets a lot. Eat regular meals spaced evenly through the day - do not eat most of your calories at dinner. Get 22-30 min of exercise (a brisk walk) every day. Avoid packaged foods, avoid eating out, eat fresh food that you prepare from scratch most of the time. You can do it.
