Bottom line:  While there might be a ‘metabolic advantage’ to a ketogenic diet over one containing a fair amount of carbohydrate, on average the difference is small.  This does not explain why some people seem to lose weight relatively easily when carbs are restricted, which may be due to inter-individual variation. However the common observation of significant and sustained weight loss over months and years (Hallberg et al, 2018) is more likely a result of the benefits of nutritional ketosis on fuel flow, appetite, and cravings; as well as the reduced inflammation that is triggered by modest levels of beta-hydroxybutyrate. Clearly humans following a long-term ketogenic diet can eventually remain weight stable by adjusting fat intake to balance daily fat use for fuel.  For those wishing to lose weight additional rather than remain weight stable, one’s goal should be to reduce dietary fat intake down to the margin of satiety (just enough, but not too much) and avoid or limit non-satiating energy sources such as alcohol.

"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."
Are you like Old Faithful when it comes to your morning walk or evening jog? Know this: The more you do an activity, the more your body adapts to it, so you burn fewer calories. If you want to light a fire under your metabolism, consider cross-training. For example, if you normally walk, try biking instead. "Since you're not used to working all those different muscles, it's a more intense workout, which can translate into a greater metabolic after-burn because your body is working harder to recover and get oxygen to all your tissues," says Carol Espel, M.S., an exercise physiologist for Equinox Fitness Clubs in New York City.
Since insulin sensitivity is at its highest in the first two weeks of the menstrual cycle, and carb intake is free to be at its highest, exercise can be more aerobic (long, moderate heart-rate-elevating cardio exercises). It is at this time that you can do your best high performance cardio training. Here you can challenge yourself with longer-term exercises that may be more “stressful” for your body, like long bike rides, tabata sprints, night-long dance sessions, and the like. It is at this time in your cycle that your body can handle the most aerobic stress.
