Keto Diet – Starter – Day 1 Menu Plan & Recipes

Keto Meal Plan for me and my partner. We are based in the UK and can only purchase ingredients from a small supermarkets. I am intermittent fasting – I only eat at dinner time, and my partner eats three meals per day. This Keto meal plan includes recipes using metric measurements for ingredients for meals and a provides a shopping list for all ingredients for each. Because I only eat 1 meal per day, I need to ensure that I eat enough nutrients in the dinner to satisfy the keto requirements and fat and protein so the dinner is always a lot larger and the Breakfast and Lunch meals are smaller than recipes for two.
