Many diet plans cut out entire food groups, which can create nutrient deficiencies as well as health problems. For instance, if the diet is very low in carbohydrates and you have type 1 diabetes or type 2 diabetes, it’s probably not a good fit. And if it’s too restrictive and you’re pregnant or breastfeeding, it’s not a good idea, either. Keep in mind that pregnancy is not a time for weight loss. Speak with your doctor before making any changes to your diet if you are pregnant or breast-feeding.

The claims made about the health implications of carbohydrates and protein are controversial. As with other fad diets, one nutrient is being made to look like the enemy (carbohydrates), while protein is made to look like the key to weight loss and health. Most diets that are against carbohydrates use the arguments that we consume less fat and more carbohydrates than we did 10 years ago, and obesity is on the rise. This is half true. We consume more carbohydrates, which means we consume more calories. Our fat intake remains above the recommendations, but the percent of our total calories from fat has come down because we are now consuming more calories. Again, research clearly shows that a balance of each of these nutrients is needed and that an excess or deficiency in any of them will cause problems. This diet can be difficult to stick with long-term, so weight regain can be an issue.
High blood sugar levels coupled with high blood ketones, on the other hand, will mean that you have a pathologically low level of insulin – something non-diabetics do not suffer from. This can lead to ketoacidosis – a potentially life-threatening condition. If this happens, you’ll need to inject more insulin; if you’re at all unsure of what to do, contact a medical professional. Coveting really high blood ketones for weight control is not worth the risk for type 1 diabetics.
Lastly, as I indicated, all my lifts are going up, but my weight (and even LBM, assuming my scale is even remotely accurate) so is it fair to say that strength gains are not directly related to muscle gains? Is this the “beginner” phase that you speak of frequently? The scale would indicate that muscle is going down….. But my presses, squats, deadlifts are all up.
