You've likely heard horror stories of what competitors feel like when they cut carbs low, or when the average bro talks about going keto. However, the odds are that those people were not actually in nutritional ketosis, or more importantly, following a well-formulated ketogenic diet. Yes, you may experience some fogginess and discomfort, but it doesn't have to be intense if you handle it right.
In contrast, multivitamins aren’t a good solution as they are synthetic and lack a lot of nutrients like polyphenols, antioxidants and fiber that green powders and whole food sources provide. And the lack of fats and enzymes make the nutrients they do contain very difficult to process properly. Just because you’re putting something in your body doesn’t mean your body can use it.
"Sunflower seeds are a great snack option whether you follow a keto diet or not," says registered dietitian Katey Davidson, M.S., R.D. Although all sunflower seeds are an excellent source of healthy unsaturated fats, protein, and vitamin E, many companies use flavorings to season their products which can be high in both salt and sugar, says Davidson. She recommends Terrasoul Superfoods because they aren't flavored or salted. And with only 6 grams of carbs and 1 gram of sugar (per one 1/4 cup), you won't have to worry about these seeds throwing you out of your hard-earned ketosis. However, Davidson says you'll want to aim to eat just a handful of seeds, which is considered a serving. (Related: This keto smoothie recipe is delicious even without a ton of fruit.)
So people saying that – despite the lack of scientific support – likely have a financial reason to say it. Some of these products are sold under something like a multi-level marketing arrangement, so sales people are entirely paid based on commission. For example, the company Prüvit sells drinkable ketones, called KETO//OS with a multi-level marketing structure.
