Author Daniela Jakubowicz, MD, claims that when you eat certain foods matters when you're trying to lose weight or keep it off. Jakubowicz, an endocrinologist, notes that hormones that control your appetite, energy, and metabolism vary naturally around the clock.
Her plan tells you how much protein, carbs, fats, and sugar to eat within 15 minutes of waking up each morning. That will boost your metabolism and tame your afternoon or evening cravings for junk food, she says.
Along with a bigger breakfast, the plan calls for a smaller lunch and dinner.
Does It Work?
Jakubowicz created the diet while treating people with health problems linked to weight gain, like type 2 diabetes. In a 2012 study she led of 195 overweight men and women, those who went on the Big Breakfast Diet lost about the same amount of weight as those who ate low-carb breakfasts over 4 months.
Over the next 4 months, though, the big-breakfast dieters were less likely to regain weight or have food cravings.
What You Can Eat and What You Can’t
For breakfast, you get seven protein servings, two servings each of carbohydrates and fat, and one serving of sweets.
A breakfast sweet can be jelly beans, a doughnut, or a piece of cake.
You can't eat carbs or sweets at lunch or dinner. You eat less protein than at breakfast, along with fruits and vegetables.
You can have sugar-free drinks, gum, and bouillon any time of day.
After a month on the diet, you can have an alcoholic drink with a meal once in a while. Jakubowicz advises low-sugar vodka- or whiskey-based drinks over beer or wine.
Level of Effort: Medium
A large breakfast and small dinner might be hard to get used to. You never skip breakfast on this plan.
