Breakfast options
A good low-carb breakfast is built around protein and natural fat with almost no sugar or starch, which keeps you full through the morning and steadies your blood sugar. The simplest version is eggs. A high-protein, egg-based breakfast has been shown to increase fullness and reduce how much people eat later in the day,1 and scrambled eggs are a perfect low-carb breakfast for any day.Our goal with the low-carb challenge is to make it as simple and tasty as possible, so start with scrambled eggs and add whatever you like. Choose one option, several, or all of them:
- Fried bacon (you may have to buy some extra to add this on weekdays too)
- Butter on top of the eggs
- Smoked salmon (additional shopping required)
- Cheese on top of the eggs (sliced or grated, let melt on top)
- ½ – 1 avocado (additional shopping required)
Other options
Feel free to switch breakfast at any time – every day if you want – to any of the recommended below. Some extra ingredients may have to be bought (see below).
- Bacon & eggs: You may need to buy additional bacon, if you want this on weekdays too
- Scrambled eggs with spinach and smoked salmon: Requires buying some spinach and smoked salmon.
- Egg muffins: Requires buying a couple of additional scallions, some more bacon or chorizo, more shredded cheese and possibly extra pesto.
- Boiled eggs: Buy additional avocado or asparagus if you want to add.
- Dairy-free latte: Buy coconut oil, vanilla extract and ground ginger.
- Fried eggs with tomato and cheese: Buy a tomato and more cheese.
More breakfast options with additional shopping
These breakfasts require some additional shopping; pickled jalapeños for the mexican scrambled eggs, and fresh spinach for the frittata.
The no-breakfast option
Skipping breakfast is normally fine on a low-carb, high-fat diet – as long as you’re not hungry.2 It may speed up weight loss and diabetes reversal.3
However, we do not recommend starting this habit during the two-week challenge. It’s better to change one thing at a time – what you eat.
Once you’ve gotten used to eating low carb – which normally takes several weeks – you may be ready to add intermittent fasting, like skipping breakfast.

The old idea that breakfast is important for health or weight control is mainly based on observational studies, a notoriously weak form of evidence.
When tested this idea does not appear to hold up, at least not for weight loss. A recent meta-analysis of randomized clinical trials found that people assigned to skip breakfast ate less overall and lost more weight than those assigned to eat breakfast daily:
British Medical Journal 2019: Effect of breakfast on weight and energy intake: systematic review and meta-analysis of randomised controlled trials [strong evidence]
Even the observational data is inconsistent, for example with findings like in the study below: “compared to breakfast eating, skipping breakfast was significantly associated with better health-related quality of life and lower perceived stress.”

To our knowledge, there are still no randomized trials exploring the effect of true (zero calorie) intermittent fasting on type 2 diabetes. Here are the best existing studies:
BMJ Case Reports 2018: Therapeutic use of intermittent fasting for people with type 2 diabetes as an alternative to insulin [very weak evidence]
JAMA Network Open 2018: Effect of intermittent compared with continuous energy restricted diet on glycemic control in patients with type 2 diabetes: a randomized noninferiority trial [moderate evidence]
Diabetes Research and Clinical Practice 2016: The effects of intermittent compared to continuous energy restriction on glycaemic control in type 2 diabetes; a pragmatic pilot trial [moderate evidence] ↩
