I try to munch on veggies to get a little but sometimes it just not enough. But eventually I feel OK with minimal carbs. My theory is the body adjusts to minimal carbs & starts to reach for fat for energy.........but it's a fine line........don't want it to burn any muscle. After you've gotten down to where you wanna be you take more in.....as long as you stay active.
"Eighty percent of your ability to achieve body composition goals is determined by your diet- essentially, your ability to moderate insulin production so you can access and burn stored body fat for energy, while preserving or building muscle. Insulin in an important hormone that transports nutrients into cells for storage. When the delicate insulin balance is abused by habitually consuming too many carbs, cells become insulin resistant; more fat is stored and it becomes increasingly difficult to burn. This sets the stage for the development of serious conditions like Metabolic Syndrome, type 2 diabetes, and heart disease. Synthesis of testosterone and human growth hormone are hindered by excessive insulin production, creating an artificially accelerated aging process. There are also serious immediate drawbacks to consuming high-carb snacks and meals. the sugar-high insulin-release response cycle causes problems with fatigue, mental focus, mood swings, and jitters, resulting in similar conditions to burnout."
Carbohydrates control insulin, and insulin controls fat storage.
The reason for being lightheaded, Ketosis. "If the diet is changed from a highly
glycemic
diet to a diet that does not provide sufficient carbohydrate to
replenish glycogen stores, the body goes through a set of stages to
enter ketosis. During the initial stages of this process, blood glucose
levels are maintained through
gluconeogenesis, and the adult
brain
does not burn ketones. However, the brain makes immediate use of
ketones for lipid synthesis in the brain. After about 48 hours of this
process, the brain starts burning ketones in order to more directly use
the energy from the fat stores that are being depended upon, and to
reserve the glucose only for its absolute needs, thus avoiding the
depletion of the body's protein store in the muscles"
The anti-ketosis conclusions have been challenged by a number of doctors and advocates of
low-carbohydrate diets, who dispute assertions that the body has a preference for glucose and that there are dangers associated with ketosis.
[16][17][18] It has been argued that the
Inuit
lived for thousands of years on a diet that would have been ketogenic,
and there are many documented cases of modern humans living in these
societies for extended periods of time.
[weasel words][by whom?] On the other hand, it is speculated by
Nick Lane [19]
that the Inuit may have a genetic predisposition allowing them to
healthfully eat a ketogenic diet. According to this view, such an
evolutionary adaptation would have been caused by environmental
stresses.
[20] While it is believed that carbohydrate intake after exercise is the most effective way of replacing depleted glycogen stores,
[21][22]
studies have shown that, after a period of 2–4 weeks of adaptation,
physical endurance (as opposed to physical intensity) is unaffected by
ketosis, as long as the diet contains high amounts of fat.

There is so much shit out there
This is the shit that I feel is true, however.
