Yes and no. Quality of calories matters. Your body will not burn sugar the same way as quality proteins, fats and complex carbs.
High intake of sugars is counterproductive.
I'm thinking steak and eggs for breakfast (steak, not sausage or bacon) is probably more conducive to weight loss than a diet shake. More calories, but they're the kind that keep you from getting hungry again a couple hours later. Portion control is of course important.
I generally rotate through steak and eggs, oatmeal with blueberries and honey, and once a week Kodiak cakes as my pancake breakfast. If I'm really just not feeling hungry for breakfast, then a banana and some yogurt.
I'm no expert, this is just what works for me coupled with at least 30min of exercise six days a week. Also eating my biggest meals at breakfast and lunch (which is essentially my dinner) and just a small meal or snack no later than 4-5pm. I try not to eat anything after 5-6pm.
Sunday is my "cheat day" where I might have eggs and lingucia with toast and jam for breakfast or else real pancakes with tons of maple syrup, pizza and beer for lunch, and a whiskey in the hammock in the afternoon instead of exercise. :)
