Post Crunchy Pecan Great Grains

Jennifer Singh, RD, LDN, said that her rule of thumb for cereal is less than 10 grams of sugar per serving, and a combined amount of protein and fibre that surpass the sugar. Post Crunchy Pecan Great Grains [8] ($40 for a pack of seven) meets those standards and is pretty low-carb to boot. "It has good flavour and texture," Jennifer added.

She eats hers with a low-sugar yoghurt for extra protein and tops it with vanilla extract, cinnamon, coconut flakes, or chia seeds. "This makes for a breakfast that's under 300 calories, great for those trying to lose weight," she told POPSUGAR.

"Many low-carb cereals use sugar alcohols like maltitol or artificial sweeteners like sucralose," said Andres Ayesta, MS, RD, LD, owner and founder of Vive Nutrition in Tampa, Fla.

Jennifer says many of her clients love Honey Nut Cheerios, and she's found that swapping them for Multi-Grain Cheerios [11] ($16 for a two-pack) is a good compromise. She recommends eating them with milk or soy milk or with a side of hard-boiled egg or cottage cheese for extra protein.

Old-Fashioned Oatmeal

Diana Gariglio-Clelland, a registered dietitian at Balance One Supplements, recommended oatmeal like Old-Fashioned Quaker Oats [12] ($3) because it has more fibre than most cold cereals and doesn't contain any added sugar. That combo also makes it a good carb [13] and a great choice if you're trying to lose weight, she told POPSUGAR. Adding a protein source like chopped nuts makes it even more filling, which reduces hunger and cravings, Diana added.

Homemade Muesli

Diana Schaub, MS, RD, culinary and nutrition manager at Territory Foods [14], didn't recommend a specific brand. Instead, she shared her own version of a low-carb cereal: a cheap, homemade muesli recipe. Simply mix up pumpkin seeds, unsweetened coconut flakes, pecans, hemp hearts, cinnamon, vanilla, and dried blueberries, then toast it in the oven at 350 degrees for seven to eight minutes. "It's delicious on its own, in a bowl with almond milk, or on top of low-sugar Greek yoghurt," Diana said.

Quinoa

Quinoa for breakfast? Yep! Registered dietitian Shira Sussi [15] mixes a cup or half a cup of cold, cooked quinoa, like this Lundberg Tri Colour Quinoa [16] ($6), with a scoop of nut butter, a handful of berries, some maple syrup, and any kind of milk for a tasty low-carb cereal substitute. "This homemade breakfast cereal will have much less additives than any shelf-stable cereal you buy at the store," she told POPSUGAR.

It's high in protein and fibre while staying lower in sugar than most breakfast cereal. She recommended sticking to the 2/3 cup serving size if you're looking to lose weight and pairing it with a rich protein source like turkey bacon to keep you full for longer.
