60 with htn, low glucose, high cholesterol. What is best diet?

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.
