It’s generally accepted that the healthiest diets have carbs account for at least 45% of your diet. I wouldn’t trust a diet that tells you to neglect an entire food group.

LCHF diets have proven to be more effective for weight loss than other nutrient-based diets. However, this doesn't mean they are healthy.

The [Low Carb High Fat diet] (https://lowcarbdownunder.com.au/faq/what-is-a-low-carb-high-fat-diet/) essentially consists of eating fewer carbohydrates and more fats.

• The basic premise of weight-loss dieting is pretty simple: if you eat more calories than you burn, you gain weight & vice versa. No macro-nutrient group (fat, carbs, protein) will necessarily make you lose or gain weight. Eating too much of anything can result in a caloric increase.
• However, fat is [the most energy-dense] (https://healthyeating.sfgate.com/energydense-macronutrients-7432.html) of these nutrients — with 9 calories per gram compared to 4 calories per gram in carbs and protein.

Because of this, multiple studies have shown that consuming more fats and fewer carbs can aid weight loss.

• And weight loss can often be a healthy thing! It lessens the risk for conditions like heart disease and diabetes. However, health is perhaps most important in the long-term sense. There isn't much research on the effects of an LCHF diet over long periods, and what little there is [doesn't look promising] (https://atlasbiomed.com/blog/explained-low-carb-diets-have-health-risks/).
• In addition to this — there are many different kinds of carbs and fats, some better for you and [some worse] (https://www.healthline.com/health/heart-disease/good-fats-vs-bad-fats). Vilifying entire nutrient groups can result in restrictive and potentially unhealthy eating.
• It can also take a mental toll. Physical health is important and the food you eat makes up a large part of that. But dieting and stressing about food/nutrients can be harmful to mental wellbeing, resulting in issues like [orthorexia] (https://www.healthline.com/nutrition/orthorexia-nervosa-101).

if you want to lose weight you're going to need to either cut fat or cut carbs.
*Cutting fat for a long period is not sustainable as it leads to nutritionally deficiencies.

• Cutting carbs is a lot easier for some people but you need to know the science behind it and how to do it properly.
• A lot of people will neglect protein although ketones are protein sparing this will negatively impact you in the long run
• There are electrolyte imbalances that occur early on this causes most of the side effects people face.
• Any diet should focus on nutritionally density but there are still processed foods that are considered low carb and void of nutritional value
• The type of fat is the most important you should avoid omega 6 and processed seed oils.
• Low carb diets tend to eat a lot of fibre rich foods this can cause issues for some people in regards to gut mobility.
• There is heavy reliance on greens which cause lead to oxalate accumulation overtime similar with a vegan diet.
• Although this take is controversial and talking from experience. I believe this to be optimal for hypothyroid patients due to their poorer ability to process carbohydrates and while these diets can reduce active thyroid hormone T3 it does not lower metabolic rate and returns after eating carbohydrate. The only danger is a lot of low carb foods are goitrogenic .
• Ketogenic style diets have been shown to retard adaptive thermogenesis meaning you can lose weight while maintaining a higher metabolism.
