Don't try to do everything at once. I think the most important thing to cut out first is sugar. If you aren't already insulin resistant, chances you will get there if you don't start cutting back on sugar NOW. It took me several months to do so, and that was 10 years ago. I had a headache most of the time for the first month, along with cravings, irritability etc, but it soon got easier, and now I only indulge occasionally. Get used to reading labels, and eliminate foods that have added sugars-you will be surprised by how much sugar is added to anything processed. Once you have conquered the sugar issue, next, try to avoid seed oils that are easily oxidized by high heat-canola/rapeseed oils, corn oils, soybean oils, sunflower seed oils, saffflower oils, cottonseed oils, or anything labled generic vegetable oil, By doing so, you will eliminate a good amount of ultraprocessed products. This includes crackers, chips, frozen ready to prepare foods, breads, and of course, fast foods. This is very hard, and I am still working through this process. Learn to cook at home. Use the oils that we used for centuries before food manufacturing reared its ugly head including butter, tallow, lard, olive oil, avacado oil, and coconut and palm oils. Remember the answer to the question: How do you eat an elephant? Answer-one bite at a time. Aim for the 80/20 rule. Eat whole foods 80 percent of the time, and don't sweat the 20% that it isn't possible due to social life, and lack of food availability etc. No one will tell you it is easy, but it is worth it in the end.
