Eat fat only until full. Don’t eat any more than you can handle. Sometimes people think they have to eat lots of fat whereas it is really eating the fat that naturally comes with a meal (i.e:not trimming a fatty steak) and adding as much fat as feels right to your meals through sauces and cheese for example. I don’t go our of my way to eat extra fat. If you are still hungry though but don’t feel like the heavy feeling some fat brings, add some coconut cream to your smoothies.
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.
Take a break from breakfast: If you’re not hungry, feel free to skip breakfast and just have coffee (with some milk if you want it). Many people find that within a few days of eating low-carb, high-fat meals, cravings and hunger decrease significantly. This can make it easy to skip a meal, perhaps especially breakfast. Skipping a meal is cheap, fast, and might increase the diet’s effectiveness for weight loss and diabetes. See intermittent fasting
You made me smile with the food leper reference. Love it. As for snacks, there is a page here and here to look at and here is my snack finder. Boiled eggs, avocados, pork crackling, nuts, fat bombs, calamari, granola bars, cold meats … I hope these give you some ideas. Eventually the goal is to stop snacking, but in theme time, these might help you out.
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.
