Dairy products contain varying amounts of lactose (milk sugar), which slows down weight loss. What’s more, part of the protein in milk generates a significant insulin response, which can have the same effect. Consequently, cutting back on dairy products may accelerate weight loss. This applies especially to dairy products typically lacking in fat, such as regular milk and various yogurts, but be careful with full-fat dairy such as cream and cheese all the same. And don’t forget whey protein powder, which is pure milk protein.
If you don't eat meat — or any animal products, for that matter — or if you have a food allergy, you can replace anything on the meal plan with foods that have a similar calorie count and provide the same nutrients. For example, instead of eating half a cup of tuna, you can eat about 2/3 cup of tofu. Instead of eating an egg at breakfast, you can drink a cup of soy milk. On day two of the military diet, cottage cheese substitution ideas include 15-20 almonds. Almonds work to sub out the slice of cheddar cheese, too. And instead of peanut butter, you can spread almond butter or sunflower butter on your toast for breakfast of day one.
Lots of apps and website offer keto diet challenges—basically, a blueprint for the keto diet with a fixed starting and ending point (they typically last for a week to a month, though some may be longer). Speaking of apps, plenty of keto-centric ones are right at your fingertips (a.k.a., your smartphone), like the KetoDiet app, which can help you calculate your macros and track your keto diet effectively.
