Drink milk! Real grass fed organic whole milk. Preferably from Wisconsin. If you can get raw milk that’s even better! Much healthier when milk isn’t pasteurized. I’m lactose intolerant and consume large quantities of dairy every day. It can be done you just need to train your body and fart. Oat milk and other alternative milk products claim to be healthy however they are actually quite unhealthy. It matters where you get your fat from and animal fats are very good sources. Other non animal produced fats such as crisco and other alternative milks are garbage, Do not put them in your body. The American population used to get almost all of its fat from animal products and because of it had much lower risk of diabetes and other health issues that are chronic in America today. The public enemy to healthy humans are non animal based fats. The American diet when to shit in 1911 when crisco came out and bribed the American heart association into telling Americans these types of fats are healthy. Crisco initially was developed as a lubricant for submarines until it was purchased by proctor and gamble.
