Most trials, across various health condition, have seen a keto diet modestly increase HDL-C levels. This can be due, in part, to an increase in overall fat intake. Some people may need to lower this to under 20 grams, and some can produce more ketones even above 50 grams.
To understand the cause of keto breath, it’s important to understand how metabolism works. Your body gets energy from a variety of food sources, including carbohydrates, fat, and protein.
This energy is in the form of molecules called ‘ketones’. Supplements may be necessary for the majority of people on a keto diet. Food restrictions also may decrease total phytonutrient and dietary fiber consumption, leading to constipation and deleterious effects on the gut microbiome. Studies on weight change of participants on a low-fat diet compared to a diet with 35 to 65 percent of calories from carbohydrate foods continue to find no significant long-term differences. However, there is strong evidence that ketogenic diets better support weight loss.
