Last year while I was going grain free/LCHF, I decided to get him and his siblings gluten free (While planning to eventually get him completely grain free, however that hasn’t gone to plan yet lol!) The futher away from gluten he was, the more veges he started to willing eat. We just started him off with carrots as he seemed to like them more than other veges. He loves potatoes and meat so we would tell him have a carrot then you can choose to have a mouthful of potato/meat then have another carrot etc. We just kept perserving, adding in the other veges and adding in more (Eg you can have some potato after you have eaten 4 carrots etc) and now a few months ago for the first time he cleaned off ALL his veges before he even touched potato or meat without being asked. It hasn’t happened again since BUT he will eat all of one food group before having something else.
Use fat as a lever. We’ve been taught to fear fat, but don’t! Both keto and low carb are high fat diets. Fat is our source of energy as well as satiety. The key to understand, though, is that fat is a lever on a low carb or keto diet. Carbs and protein stay constant, and fat is the one you increase or decrease (push the lever up or down) to gain or lose weight, respectively. So if your goal is weight loss, eat enough fat to be satisfied, but there’s no need to “get your fats in” once you’re satisfied.
