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.
Exercise will help you increase your metabolism and is key to how lose weight fast, It tones your body, tightens up excess skin, increases your stamina, gives you more energy, and makes you happier and healthier. And for those reasons it is important to rapid weight loss, but it’s not everything! It will help you stay on plan and stay motivated, so find an exercise you love and do it.
What I find very off-putting though is the complicated maths that seems to go with everything I’ve read on working out food ratios on this eating plan. I’m just cutting out all carbs, eating some protein, lots of green veg, a few berries occasionally and lots of good fats – olives, olive oil, MCT capsules, coconut oil, butter, avocados and nuts and seeds, and drinking lots of water. I’m not able to exercise presently, apart from walking a little, due to my injuries. I usually practise and teach yoga. Is it sufficient to approach it in this way?
I actually woke up this morning thinking that just as we plan our days, our social lives, our journeys so we need to really plan what we eat and – like a route map – and stick to it without deviation if we want to reach our goal. So that’s what I’m about to try. It is, however, all too easy, come the weekend, to be influenced by those around us who are not so bothered by their reflection in the mirror. But to be true to myself I am going to listen to my body and be strong in aiming for that end goal and not succumb to all those crisps with double gin and tonics(!), slices of toast with eggs for breakfast and snacks that I am given that I haven’t been in control of making. I’m going to ask if I am actually hungry or just bored or just being plain greedy. I will need to politely decline my husband’s pampering treats of cheese, pickle on brown bread – or offer to make a more healthy snack of my choice and making – crisp bread, crudités. Or perhaps I’ll simply half the snack and give my husband the other. I’ll listen to my body.
“I learned how to cook from scratch and experiment with flavors. The biggest change my husband Mark and I made was planning our meals for the week on Sundays. We also rely on food optimizing—using vegetables to bulk up our meals but still keep them low-calorie. It helped me lose 52 pounds and 8 dress sizes, while Mark lost 110 pounds.” —Amanda Gibbon, 46
"Order without looking at the menu. Almost every restaurant has the basics—veggies, grains, and protein. If you go in knowing what you want, I guarantee you'll be able to make a meal. If you're too uncomfortable to ask for what you need, tell a white lie: Say you're allergic. I know it's controversial to suggest this, but women in particular can really have trouble standing up for their own needs. So if you want the broccoli soup puréed without cream, tell the waiter you're lactose intolerant."
Scientists and nutrition experts like it too and are saying it’s the way of the future for losing and keeping weight off and new books and articles on the topic are being published daily including best selling books like ‘Eat Stop Eat’ and ‘The 8 Hour Diet’. Intermittent fasting is also popular with followers of the Paleo diet since our ancestors appear to have eaten this way for thousands of years.
